The World's First Solar Road Is Open in
France

The first solar road has opened in Normandy, France. The kilometer-long stretch of road is
expected to generate enough electricity to power a nearby village of over 3000 people.
Solar roads are a controversial and mostly untested new technology. A solar bike path
wasbuilt two years ago in the Netherlandsand only managed to generate enough
electricity to power a single home. It was estimated that the cost of that bike path could
pay for over 100 times as much electricity from other sources.
The solar road in France has even more of an uphill battle. In Normandy, where the road
was built, there are typically less than two months of strong sunshine a year.
However, if this test produces as much power as it's expected to, and the company
building the roads, Wattway, can bring down the costs of future panels, it's possible solar
roads could become a good investment.
La France inaugure la première route
solaire au monde
Source URL: http://www.challenges.fr/entreprise/environnement/la-premiere-route-
solaire-au-monde-inauguree-en-normandie_444150
La première route solaire au monde a été inaugurée jeudi 22 décembre par la ministre
Ségolène Royal dans un village normand, une technologie en phase test, expérimentée en
France par la filiale de Bouygues, Colas, à laquelle travaillent également Néerlandais,
Américains et Allemands. A partir de jeudi, les 2.000 automobilistes qui empruntent en
moyenne chaque jour la RD5 pour sortir de Tourouvre rouleront pendant 1 km sur des
panneaux solaires collés sur la chaussée.
Ces 2.800 m2 de dalles aux allures de carrelage plastifié doivent permettre de produire
l'équivalent de l'éclairage public d'une ville de 5.000 habitants, selon la direction de
Wattway, le projet co-inventé par Colas et le CEA Tech. Elles sont fabriquées par la Scop
SNA à Tourouvre. L'ensemble des travaux est couvert par une subvention d'Etat de 5
millions d'euros hors taxe, précise le conseil départemental.
"Ce nouvel usage de l'énergie solaire permet de profiter des grandes surfaces
d'infrastructures routières, déjà utilisées aussi bien par les transports, voitures, vélos,
piétons, pour produire de l'électricité sans mobiliser de foncier supplémentaire", se félicite
le ministère dans un communiqué. Confiante dans cette technologie, Ségolène Royal a
annoncé un "plan de déploiement national des routes solaires". Ce plan se traduira par le
lancement d'un "appel d'offres innovation pour encourager le développement de
technologies solaires innovantes".
Depuis quelques mois, le concept est déjà expérimenté sur quatre sites pilotes (deux en
Vendée, un à Septèmes-les-Vallons, près de Marseille, un dans les Yvelines) sur des
parkings, ou devant des bâtiments publics. Les surfaces sont beaucoup plus petites, de
50 à 100 m2 de dalles solaires.
A la Roche-sur-Yon, par exemple, depuis juin, "pratiquement tous les week-ends des
voitures électriques viennent recharger leur batterie à la borne du complexe sportif et
culturel Vendéspace, alimentée par 50 m2 de dalles solaires. Les cellules photovoltaïques
n'ont pas bougé. Ca fonctionne parfaitement bien", assure à l'AFP le député LR de la
Vendée Alain Leboeuf qui préside le Syndicat départemental d'énergie (Sydev), partenaire
de cette expérimentation. Ailleurs, les dalles pourraient alimenter les aires d'autoroutes ou
les maisons isolées, précise Wattway.
"Première mondiale"
La route solaire ornaise est une "première mondiale", explique Jean-Charles Broizat,
directeur de Wattway, ce que confirment les concurrents. Au nord d'Amsterdam, une
piste cyclable solaire de 70 m est en service depuis deux ans, sur une voie où passent
quelques 2.000 vélos par jour. Si le revêtement a mal résisté au premier hiver, le problème
a été résolu depuis: la piste "SolaRoad" vient d'être prolongée de 20 mètres, assure TNO,
société à l'origine du projet. "Nous avons des projets de routes solaires publiques pour
2018", précise Sten de Wit, de TNO.
L'Allemagne est aussi sur les rangs. "Nous projetons une route test de 150 m près de
Cologne à l'été 2017, puis une route publique fin 2017", explique Donald Müller-Judex,
ingénieur à l'origine du projet Solmove, basé en Bavière.
Aux Etats-Unis, le Missouri "travaille" à l'installation d'environ 19 m2 sur un trottoir à
proximité de la Route 66, indique à l'AFP Tom Blair, ingénieur au ministère des Transports
de cet Etat (MoDOT) sans donner de date.
Avantages et inconvénients
A chaque fois, le concept est de coller sur la route des panneaux solaires protégés par
une résine pour produire de l'électricité. Avantage: la production d'électricité ne gêne
personne sur ces surfaces qui ne sont en moyenne occupées par les voitures que 20%
du temps, selon Colas. Avec un million de km de routes, la France pourrait ainsi en
théorie accéder à l'indépendance énergétique en pavant le quart de ses routes, met en
avant la société.
Inconvénient: les panneaux à plat produisent moins d'électricité que les panneaux
inclinés. Pour "300 kWh installés", les dalles Wattway produisent "5 à 10 kW de moins"
que les toitures, selon M. Broizat. Les sceptiques attendent aussi de voir si les panneaux
résisteront effectivement, avec le temps, en dehors des laboratoires, au passage des
poids-lourds et aux intempéries.
Surtout, le modèle économique reste à trouver: "Aujourd'hui Wattway est à 17 euros le
watt-crête (unité de mesure de l'énergie solaire) raccordé", selon M. Broizat, contre 1,3
euro pour le solaire en grande toiture, selon le syndicat des énergies renouvelables (SER).
Mais Wattway compte d'ici à 2020, "rejoindre" le prix de production dusolaire classique.
Un objectif "ambitieux" mais "réaliste", selon Colas. Car le coût de production de
l'énergie solaire classique a diminué de 60% entre 2009 et 2015, selon le SER.

Prioritizing Upgrades for Smart Energy
Solutions
Source URL: http://www.iotevolutionworld.com/iiot/articles/428189-prioritizing-
upgrades-smart-energy-solutions.htm
By Special Guest Consuelo Azuaje December 20, 2016
There are over 3000 utilities companies supplying $400 billion dollars’ worth of electric
power in the US. The US power grid is so massive that it was coined “the largest machine
in the world” a few years ago by Bloomberg journalists Mark Chediak and Ken Wells.
Therefore, to say that updating legacy power grid infrastructure and adapting it to
increasingly demanding efficiency regulations and energy needs (such as bi-directional
power flow) would be challenging is an understatement. The Internet of Things (IoT) could
be used as a tool by power companies to gather and analyze the massive amounts of
data needed to yield smart energy results. Thus the IoT could be used to streamline
operations, eliminate inefficiencies, and ultimately modernize the power grid.
Smart energy applications go far beyond simple electrification and, ranging from top to
bottom, often have little in common beyond their shared use of a power source (e.g.,
HVAC monitoring of individual buildings, smart metering, fault detection, etc.). There are
scenarios that highlight the need for the IoT in the energy sector. Imagine the fallout of a
natural disaster wiping out large sections of powerlines and causing blackouts in a
number of different areas. Remember what Hurricane Sandy did in 2012? Or what
Hurricane Katrina did in 2005? In those cases, the IoT would be used for triage to quickly
sort out which areas—such as those with hospitals or senior care facilities—should have
their energy needs addressed first. The IoT would be used to bring back power as swiftly,
effectively, and efficiently as possible.
Applications aside, a smart power grid would—by nature—operate more efficiently than
traditional grids do. For a hundred years, power companies relied solely on human
workers to read meters, look for/inspect broken equipment, and monitor voltage. In a
smart grid, those tasks would be automated. Smart grids would perform constant self-
assessment to detect/respond to network disturbances and to restore grid operations
when needed. This saves power companies time and money; in a 2010 report, the Electric
Power Research Institute (EPRI) estimated annual losses due to power disturbances are
on the order of $100 billion. Smart grid maintenance, thus, would be much more targeted,
efficient, and effective (i.e. less broken equipment) than traditional grid maintenance.
Despite the capabilities and benefits it offers, however, figuring out where to start is a
daunting task owing to the complexity and cost of implementation. A smart grid would
automate and improve electricity generation, distribution, and use, but its construction
would demand the combined use of networking equipment, sensors, and
communications networks. The costs of implementing a smart grid in the U.S. are
staggering. The EPRI estimates it would cost $338-476 billion. The returns, however,
would be even greater—$1.3-2 trillion, according to EPRI estimates. 70% of that cost
would go solely to upgrading the infrastructure (i.e., meters, lines poles, substations, etc.).
If IoT is going to be used to improve operations, upgrades will have to start from the
bottom up. First, infrastructure must be modernized to improve operations. The power
grid infrastructure that we inherited from the past wasn’t designed for the types of
operations and demands that we have today, but we can’t start from scratch and build an
entirely new power grid. The only available option is to improve the existing technology.
After that, we can focus on enhancing efficiency and saving on cost by integrating digital
technology, distributed energy, and advances in renewable energy.
Having done these things, smart energy could begin to be used to offer value-added
services to consumers. Gridco is among those who have begun to fill the smart energy
gap. Gridco uses a Multitech gateway and embedded cellular modem to offer a utility-
scale solution that would provide more reliable, power and be able to operate with
distributed power sources, variable customer demands, increasing instances of cyber-
attacks, and increasingly demanding efficiency standards.
ElectriCities is another example of a power company stepping forward as a champion for
modern, smart energy. ElectriCities uses Digi LTE routers to obtain frequent, real-time
data—such as meter readings—on substations and generators in the field with a variety
of communications devices. Digi’s LTE routers, have saved ElectriCities over $300
thousand on telemetry charges by providing them an alternative to legacy copper
connections and fiber optics via software-defined multicarrier support enable Electricities
to switch between all North American carriers (e.g. AT&T, Verizon, etc.,) and provide
flexible, reliable service to its clients.
Utility-scale solutions are a first step towards unlocking IoT’s potential in smart energy.
From blackouts due to natural disaster to energy conservation (and cost savings) via
smart thermostats in buildings, smart energy has a lot of potential. Once a brave few start
on the path (and some already have) to smart energy the rest will inevitably follow to a
brighter, smarter future.

Edited by Alicia Young
Aria Systems, a subscription and usage-based revenue services provider, has announced
Aria for Connected Vehicles, a cloud-based offering for IoT-enabled connected cars,
heavy equipment, on-demand transportation as a service, telematics, and post-sale or
lease add-on services.
Manufacturers are shifting business models from a transactional sales focus to owning
long-term recurring customer relationships. To facilitate longer, more predictable revenue
streams, they are looking to become closer to their end customer, gain better feedback,
and align their offerings with customer choices, Aria said. Industry disruption is opening
up new opportunities for recurring revenue streams from services inside and outside the
vehicle.
Aria for Connected Vehicles is designed to be used by OEMs, third-party device
manufacturers, and service providers looking to rapidly create, introduce, test, and scale
IoT and digital products and services. It manages the monetization of innovative
subscription and usage-based IoT services without compromising enterprise-grade
scalability, performance, and security. With this platform, connected vehicle offerings can
be constructed into combinations of one-to-one and one-to-many permutations of users,
data services, and devices.
Possible through this solution is usage monitoring, monetization, and billing of on-board
diagnostics (ODB) data streams at both the IoT platform and application levels. It
integrates with smartphone apps, entitlement and provisioning systems, payment
processors, and existing accounting/GL systems to provide a single view of accounts,
activity, invoices, and accounting.
The connected vehicle moves cars, equipment, and machinery from a simple world of
isolated tasks to being interactive providers of information for end consumers of value-
added digital services that improve productivity, enable innovative practices, and increase
safety. The OEM capitalizes on these closer relationships through increased revenue from
digital services and stronger brand loyalty, leading to reuse and repurchase.
Aria for Connected Vehicles enables: on-demand access to cars, equipment, and
machinery by the hour; subscription to a pool of cars so users can swap out car types as
needed; road use and mileage tracking; giving customers access to expertise online
including rating, diagnostics, management tools, and marketing tools; recurring revenue;
data monetization via downstream analytics of driver patterns.
“IoT-enabled features have become strategic growth drivers for automobiles, farm
machinery, heavy equipment and even automobile insurance companies,” said Tom
Dibble, President & CEO, Aria Systems. “Aria for Connected Vehicles helps OEMs, third-
party providers and others monetize the tremendous opportunities arriving from the
wealth of valuable data streaming from vehicles.”
Could Cryogenic Energy Storage Solve
Renewable Energy’s Biggest Problem?
Source URL: http://www.allaboutcircuits.com/news/could-cryogenic-energy-storage-
solve-renewable-energys-biggest-problem/
One of the biggest challenges facing renewable energy as it becomes cheaper and more
ubiquitous is energy storage. A British energy storage company wants to scale up usage
of cryogenic energy storage using liquid air.
Cyrogenic energy storage (CES) utilizes low-temperature (cyrogenic) liquids as energy
storage, typically liquid air or liquid nitrogen. Scientists believe that cryogenic energy
storage and supply might help improve the usability of renewable energies.
Highview Power Storage, a company that designs and develops large-scale energy
storage for power systems, plans to construct the largest cryogenic energy storage plant
in the world. The plant will be built at a location close to Manchester, England, and will
use LAES or liquid air energy storage.
How Cryogenic Energy Storage Works
Cryogenic energy systems are broken down into three components: a charging
system, an energy store, and a discharging (or energy recovery) system.
Highview's plant will be fed electricity from land lines where the liquefaction plant will use
the electrical energy to draw in air from the surrounding environment. Once the air is
drawn in, liquid air (or, in some systems, liquid nitrogen) is generated through extremely
low-temperature refrigeration. The heat lost in this process is captured and stored until
the discharging stage. Meanwhile, the liquid air is pumped to insulated storage tanks
where it is kept at low pressure. The liquid air can be stored in these tanks for long-term
storage in large amounts as it takes up 1/700th the amount of space as ambient-
temperature air.
To discharge the stored energy, the liquid air is taken from the insulated storage tanks and
transported to a much higher-pressure area. Through the increase of pressure in the
liquid, energy is created.
Once pressurized, heat (or a higher temperature waste) is applied to the liquid air through
heat exchangers. The resulting high-pressure gas is then fed through a turbine to provide
electrical energy to the required source.
Below is an illustration of this process:

The Role of CES in Renewable Energy
The incredible thing about this process is its efficiency.
Solar and wind renewable energy sources cannot produce when there is no sunshine or
airflow, respectively. Similarly, CES isn't restrained geographically like hydropower is in
order to move water uphill. Cryogenic energy storage helps renewable energy sources to
sidestep the problem of environmental factors by allowing intermittent (and sometimes
unreliable) energy to be stored.
Gareth Brett, CEO of Highview Power Storage told BBC Science: "Anywhere that needs
large-scale long-duration storage—that might be to help integrate an offshore wind farm
—a system like ours can help achieve that."
Thus far, other forms of renewable storage, such as used for solar, can get costly as the
size of the plant increases due to batteries. With LAES, this is not the case, giving it an
advantage among renewable energy storage systems. CES also doesn't require any
harmful or toxic metals that are so often associated with large-scale battery systems.
Below is a rendering of the proposed gigaplant that is projected to produce
200MW/1.2GWh:
Rendering of the proposed gigaplant. Image courtesy of Highview Power Storage
Another advantage to this LAES system is that it is able to use its own excess waste heat
(and cold, as well) as from other systems. The proposed power plant will be located next
to the Pilsworth landfill gas generation site. The Pilsworth plant puts out methane gas as it
decomposes trash, which is used to generate electrical energy. The LAES plant will
collect this waste heat from the methane and boost the efficiency of the cryogenic
process.
As renewable energy becomes cheaper, it will need better infrastructure to store and
discharge the power it harvests. LAES could be pivotal in helping renewable energy
sources truly claim their place in the energy industry.
IoT Connected Lighting in Commercial
Buildings
Source URL: http://www.iotevolutionworld.com/smart-home/articles/428194-iot-
connected-lighting-commercial-buildings.htm
By Special GuestAlex Pop, Alex Pop is a writer on behalf of The Window Experts
December 20, 2016
Smart lighting allows individuals to control lights in imaginative ways, and use them as
valuable information points for collecting and sharing information about one’s facilities.
With smart lighting poised to revolutionize both the lighting and networking industries,
some business owners are finding it a boon, while others are still finding it complicated
and are, understandably, resistant to change.
Let There be Light
One need only look at Cisco’s innovation center to find that the future of commercial
smart lighting is already here. The Berlin-based, 100 person office has no light switches;
instead, over 5,000 sensors control lighting and climate - feeding this data into Cisco’s
central IT systems - where the company can do some pretty cool things with it.
Smart Lighting: A Boon
With all the lights in the building connected to motion sensors, the company is harvesting
data about its 13,000 square foot facility through lights connected to motion sensors. The
ceiling panels respond to network commands for on/off, brightness, color, and color
temperature. Cisco claims these modern improvements have helped curtail costs as they
only turn on when they need to be in use. They also help to highlight the high-traffic areas
of the building, offering data on building occupancy, while creating a more ergonomic
work environment for its workers, putting to use low-traffic zones, while minimizing
congestion in other areas.
Cisco is leading by example; LEDs Magazine finds that the hardware and telecom
company has already implemented IoT connected lighting in its San Jose headquarters
and regional center in Toronto. Its UK headquarters in London will soon follow, while the
Berlin office will double the amount of sensors from 5,000 to 10,000 (Source).
Smart Lighting: A Bane
Meanwhile, individuals and business owners may be asking themselves what all the
hoopla is about. For residents and small businesses who may not have the electrical
wiring and networking know-how to replace one’s existing light bulbs - and run the
complex APIs necessary to link smart lights to other “smart systems” of the house - the
feat can seem daunting and disadvantageous.
A funny tweet managed to capture the frustration of going from light switches to WiFi
controlled light switches (Source). Cisco is a global company with individuals talented
enough to implement these Power over Ethernet solutions; the rest of us still need to play
catch up.
It’s safe to say that unless you, the business owner or manager, have a large, 10,000
square foot facility, then you don’t need to shell out the upfront costs that will replace your
dumb lights with smart ones. Similarly, you may not be ready to implement these changes
if you do nothing with the data these motion sensor activated lights collect.
Final Thoughts
Smart lighting is currently a multi-billion dollar market, with applications in residential,
office, shop, hospitality, industrial, outdoor, and architectural (Source). One Harvard chief,
heavily into research and development claims that the entire lighting industry supply chain
needs to get on board with the IoT and advanced lighting controls or be left behind
(Source). One thing is for sure, however: more money will be placed into lighting controls
and connected bulbs as part of a smart-home or smart-business.
3D Printed Trees Harvest Energy From
Sun, Wind, & Temperature

sun-wind-temperature/
December 17th, 2016 by Steve Hanley
Originally published on SolarLove
Can a 3D printed solar tree capture energy from the sun? Yes, say researchers at the VTT
Technical Research Centre of Finland. Not only do these little powerhouses make
electricity from the sun, they also harvest energy from the wind and changes in
temperature. VTT is the largest multi-technological applied research organization in
northern Europe. It is part of the Finnish Ministry of Employment and Economy.
The tiny leaves are made of 3D printed organic solar cells. They react to sunlight to make
enough electricity to power a cell phone or other small device. The flexible cells also
make electricity when they vibrate, which happens when the wind blows or changes in
temperature occur. The cells not only make electricity but can store it as well.
The “trunk” of the tree is manufactured from the byproducts created when real trees are
harvested and made into lumber, so the trees even smell like real wood. The tiny trees can
be used outdoors or indoors. The more “leaves” the solar tree has, the more power it
generates.
Each “leaf” is just 0.2 millimeters thick and consists of electrodes and polymer layers. The
engineers at VTT actually made them look like real leaves — well, sort of, if you squint a
little and let your imagination roam free. VTT claims 200 of its leaves are good for 3.2
amperes of electricity. It they are placed on an outdoor location, one square meter of
leaves can generate 10.4 watts in direct sunshine. Each “leaf” has its own micro-
converter built in.
The 3D printed leaves have a useful life of 2 to 3 years. VTT says they can be fully
recyclable so new ones can be produced with old materials. Thanks to their roll-to-roll
manufacturing method, they can produce up to 100 meters of leaf rolls per minute.
Innovative thinking about solar power is taking place all around the world. In
India, researchers have unveiled asolar power treethey claim can produce 5 kilowatts of
electricity while using only 4 square feet of land. For areas where open land is at a
premium, the solar trees could produce significant energy in far less space than a
conventional solar panel installation would require. Creative people are finding new ways
to harvest the free power of sunlight every day.

  • 2. The World's First Solar Road Is Open in France Source URL: http://www.popularmechanics.com/science/green-tech/a24468/first-solar- road/ Christophe Petit Tesson/EPA The first solar road has opened in Normandy, France. The kilometer-long stretch of road is expected to generate enough electricity to power a nearby village of over 3000 people. Solar roads are a controversial and mostly untested new technology. A solar bike path wasbuilt two years ago in the Netherlandsand only managed to generate enough electricity to power a single home. It was estimated that the cost of that bike path could pay for over 100 times as much electricity from other sources. The solar road in France has even more of an uphill battle. In Normandy, where the road was built, there are typically less than two months of strong sunshine a year. However, if this test produces as much power as it's expected to, and the company building the roads, Wattway, can bring down the costs of future panels, it's possible solar roads could become a good investment. La France inaugure la première route solaire au monde Source URL: http://www.challenges.fr/entreprise/environnement/la-premiere-route- solaire-au-monde-inauguree-en-normandie_444150 La première route solaire au monde a été inaugurée jeudi 22 décembre par la ministre Ségolène Royal dans un village normand, une technologie en phase test, expérimentée en France par la filiale de Bouygues, Colas, à laquelle travaillent également Néerlandais, Américains et Allemands. A partir de jeudi, les 2.000 automobilistes qui empruntent en moyenne chaque jour la RD5 pour sortir de Tourouvre rouleront pendant 1 km sur des panneaux solaires collés sur la chaussée. Ces 2.800 m2 de dalles aux allures de carrelage plastifié doivent permettre de produire l'équivalent de l'éclairage public d'une ville de 5.000 habitants, selon la direction de Wattway, le projet co-inventé par Colas et le CEA Tech. Elles sont fabriquées par la Scop SNA à Tourouvre. L'ensemble des travaux est couvert par une subvention d'Etat de 5 millions d'euros hors taxe, précise le conseil départemental. "Ce nouvel usage de l'énergie solaire permet de profiter des grandes surfaces d'infrastructures routières, déjà utilisées aussi bien par les transports, voitures, vélos, piétons, pour produire de l'électricité sans mobiliser de foncier supplémentaire", se félicite le ministère dans un communiqué. Confiante dans cette technologie, Ségolène Royal a annoncé un "plan de déploiement national des routes solaires". Ce plan se traduira par le
  • 3. lancement d'un "appel d'offres innovation pour encourager le développement de technologies solaires innovantes". Depuis quelques mois, le concept est déjà expérimenté sur quatre sites pilotes (deux en Vendée, un à Septèmes-les-Vallons, près de Marseille, un dans les Yvelines) sur des parkings, ou devant des bâtiments publics. Les surfaces sont beaucoup plus petites, de 50 à 100 m2 de dalles solaires. A la Roche-sur-Yon, par exemple, depuis juin, "pratiquement tous les week-ends des voitures électriques viennent recharger leur batterie à la borne du complexe sportif et culturel Vendéspace, alimentée par 50 m2 de dalles solaires. Les cellules photovoltaïques n'ont pas bougé. Ca fonctionne parfaitement bien", assure à l'AFP le député LR de la Vendée Alain Leboeuf qui préside le Syndicat départemental d'énergie (Sydev), partenaire de cette expérimentation. Ailleurs, les dalles pourraient alimenter les aires d'autoroutes ou les maisons isolées, précise Wattway. "Première mondiale" La route solaire ornaise est une "première mondiale", explique Jean-Charles Broizat, directeur de Wattway, ce que confirment les concurrents. Au nord d'Amsterdam, une piste cyclable solaire de 70 m est en service depuis deux ans, sur une voie où passent quelques 2.000 vélos par jour. Si le revêtement a mal résisté au premier hiver, le problème a été résolu depuis: la piste "SolaRoad" vient d'être prolongée de 20 mètres, assure TNO, société à l'origine du projet. "Nous avons des projets de routes solaires publiques pour 2018", précise Sten de Wit, de TNO. L'Allemagne est aussi sur les rangs. "Nous projetons une route test de 150 m près de Cologne à l'été 2017, puis une route publique fin 2017", explique Donald Müller-Judex, ingénieur à l'origine du projet Solmove, basé en Bavière. Aux Etats-Unis, le Missouri "travaille" à l'installation d'environ 19 m2 sur un trottoir à proximité de la Route 66, indique à l'AFP Tom Blair, ingénieur au ministère des Transports de cet Etat (MoDOT) sans donner de date. Avantages et inconvénients A chaque fois, le concept est de coller sur la route des panneaux solaires protégés par une résine pour produire de l'électricité. Avantage: la production d'électricité ne gêne personne sur ces surfaces qui ne sont en moyenne occupées par les voitures que 20% du temps, selon Colas. Avec un million de km de routes, la France pourrait ainsi en théorie accéder à l'indépendance énergétique en pavant le quart de ses routes, met en avant la société. Inconvénient: les panneaux à plat produisent moins d'électricité que les panneaux inclinés. Pour "300 kWh installés", les dalles Wattway produisent "5 à 10 kW de moins" que les toitures, selon M. Broizat. Les sceptiques attendent aussi de voir si les panneaux résisteront effectivement, avec le temps, en dehors des laboratoires, au passage des poids-lourds et aux intempéries. Surtout, le modèle économique reste à trouver: "Aujourd'hui Wattway est à 17 euros le watt-crête (unité de mesure de l'énergie solaire) raccordé", selon M. Broizat, contre 1,3
  • 4. euro pour le solaire en grande toiture, selon le syndicat des énergies renouvelables (SER). Mais Wattway compte d'ici à 2020, "rejoindre" le prix de production dusolaire classique. Un objectif "ambitieux" mais "réaliste", selon Colas. Car le coût de production de l'énergie solaire classique a diminué de 60% entre 2009 et 2015, selon le SER. (Avec AFP) Prioritizing Upgrades for Smart Energy Solutions Source URL: http://www.iotevolutionworld.com/iiot/articles/428189-prioritizing- upgrades-smart-energy-solutions.htm By Special Guest Consuelo Azuaje December 20, 2016 There are over 3000 utilities companies supplying $400 billion dollars’ worth of electric power in the US. The US power grid is so massive that it was coined “the largest machine in the world” a few years ago by Bloomberg journalists Mark Chediak and Ken Wells. Therefore, to say that updating legacy power grid infrastructure and adapting it to increasingly demanding efficiency regulations and energy needs (such as bi-directional power flow) would be challenging is an understatement. The Internet of Things (IoT) could be used as a tool by power companies to gather and analyze the massive amounts of data needed to yield smart energy results. Thus the IoT could be used to streamline operations, eliminate inefficiencies, and ultimately modernize the power grid. Smart energy applications go far beyond simple electrification and, ranging from top to bottom, often have little in common beyond their shared use of a power source (e.g., HVAC monitoring of individual buildings, smart metering, fault detection, etc.). There are scenarios that highlight the need for the IoT in the energy sector. Imagine the fallout of a natural disaster wiping out large sections of powerlines and causing blackouts in a number of different areas. Remember what Hurricane Sandy did in 2012? Or what Hurricane Katrina did in 2005? In those cases, the IoT would be used for triage to quickly sort out which areas—such as those with hospitals or senior care facilities—should have their energy needs addressed first. The IoT would be used to bring back power as swiftly, effectively, and efficiently as possible. Applications aside, a smart power grid would—by nature—operate more efficiently than traditional grids do. For a hundred years, power companies relied solely on human workers to read meters, look for/inspect broken equipment, and monitor voltage. In a smart grid, those tasks would be automated. Smart grids would perform constant self- assessment to detect/respond to network disturbances and to restore grid operations when needed. This saves power companies time and money; in a 2010 report, the Electric Power Research Institute (EPRI) estimated annual losses due to power disturbances are on the order of $100 billion. Smart grid maintenance, thus, would be much more targeted, efficient, and effective (i.e. less broken equipment) than traditional grid maintenance. Despite the capabilities and benefits it offers, however, figuring out where to start is a
  • 5. daunting task owing to the complexity and cost of implementation. A smart grid would automate and improve electricity generation, distribution, and use, but its construction would demand the combined use of networking equipment, sensors, and communications networks. The costs of implementing a smart grid in the U.S. are staggering. The EPRI estimates it would cost $338-476 billion. The returns, however, would be even greater—$1.3-2 trillion, according to EPRI estimates. 70% of that cost would go solely to upgrading the infrastructure (i.e., meters, lines poles, substations, etc.). If IoT is going to be used to improve operations, upgrades will have to start from the bottom up. First, infrastructure must be modernized to improve operations. The power grid infrastructure that we inherited from the past wasn’t designed for the types of operations and demands that we have today, but we can’t start from scratch and build an entirely new power grid. The only available option is to improve the existing technology. After that, we can focus on enhancing efficiency and saving on cost by integrating digital technology, distributed energy, and advances in renewable energy. Having done these things, smart energy could begin to be used to offer value-added services to consumers. Gridco is among those who have begun to fill the smart energy gap. Gridco uses a Multitech gateway and embedded cellular modem to offer a utility- scale solution that would provide more reliable, power and be able to operate with distributed power sources, variable customer demands, increasing instances of cyber- attacks, and increasingly demanding efficiency standards. ElectriCities is another example of a power company stepping forward as a champion for modern, smart energy. ElectriCities uses Digi LTE routers to obtain frequent, real-time data—such as meter readings—on substations and generators in the field with a variety of communications devices. Digi’s LTE routers, have saved ElectriCities over $300 thousand on telemetry charges by providing them an alternative to legacy copper connections and fiber optics via software-defined multicarrier support enable Electricities to switch between all North American carriers (e.g. AT&T, Verizon, etc.,) and provide flexible, reliable service to its clients. Utility-scale solutions are a first step towards unlocking IoT’s potential in smart energy. From blackouts due to natural disaster to energy conservation (and cost savings) via smart thermostats in buildings, smart energy has a lot of potential. Once a brave few start on the path (and some already have) to smart energy the rest will inevitably follow to a brighter, smarter future.

  • 7. Source URL: http://www.allaboutcircuits.com/news/could-cryogenic-energy-storage- solve-renewable-energys-biggest-problem/ One of the biggest challenges facing renewable energy as it becomes cheaper and more ubiquitous is energy storage. A British energy storage company wants to scale up usage of cryogenic energy storage using liquid air. Cyrogenic energy storage (CES) utilizes low-temperature (cyrogenic) liquids as energy storage, typically liquid air or liquid nitrogen. Scientists believe that cryogenic energy storage and supply might help improve the usability of renewable energies. Highview Power Storage, a company that designs and develops large-scale energy storage for power systems, plans to construct the largest cryogenic energy storage plant in the world. The plant will be built at a location close to Manchester, England, and will use LAES or liquid air energy storage. How Cryogenic Energy Storage Works Cryogenic energy systems are broken down into three components: a charging system, an energy store, and a discharging (or energy recovery) system. Highview's plant will be fed electricity from land lines where the liquefaction plant will use the electrical energy to draw in air from the surrounding environment. Once the air is drawn in, liquid air (or, in some systems, liquid nitrogen) is generated through extremely low-temperature refrigeration. The heat lost in this process is captured and stored until the discharging stage. Meanwhile, the liquid air is pumped to insulated storage tanks where it is kept at low pressure. The liquid air can be stored in these tanks for long-term storage in large amounts as it takes up 1/700th the amount of space as ambient- temperature air. To discharge the stored energy, the liquid air is taken from the insulated storage tanks and transported to a much higher-pressure area. Through the increase of pressure in the liquid, energy is created. Once pressurized, heat (or a higher temperature waste) is applied to the liquid air through heat exchangers. The resulting high-pressure gas is then fed through a turbine to provide electrical energy to the required source. Below is an illustration of this process:
  • 8. Image courtesy of Highview Power Storage The Role of CES in Renewable Energy The incredible thing about this process is its efficiency. Solar and wind renewable energy sources cannot produce when there is no sunshine or airflow, respectively. Similarly, CES isn't restrained geographically like hydropower is in order to move water uphill. Cryogenic energy storage helps renewable energy sources to sidestep the problem of environmental factors by allowing intermittent (and sometimes unreliable) energy to be stored. Gareth Brett, CEO of Highview Power Storage told BBC Science: "Anywhere that needs large-scale long-duration storage—that might be to help integrate an offshore wind farm —a system like ours can help achieve that." Thus far, other forms of renewable storage, such as used for solar, can get costly as the size of the plant increases due to batteries. With LAES, this is not the case, giving it an advantage among renewable energy storage systems. CES also doesn't require any harmful or toxic metals that are so often associated with large-scale battery systems. Below is a rendering of the proposed gigaplant that is projected to produce 200MW/1.2GWh:
  • 9. Rendering of the proposed gigaplant. Image courtesy of Highview Power Storage Another advantage to this LAES system is that it is able to use its own excess waste heat (and cold, as well) as from other systems. The proposed power plant will be located next to the Pilsworth landfill gas generation site. The Pilsworth plant puts out methane gas as it decomposes trash, which is used to generate electrical energy. The LAES plant will collect this waste heat from the methane and boost the efficiency of the cryogenic process. As renewable energy becomes cheaper, it will need better infrastructure to store and discharge the power it harvests. LAES could be pivotal in helping renewable energy sources truly claim their place in the energy industry. IoT Connected Lighting in Commercial Buildings Source URL: http://www.iotevolutionworld.com/smart-home/articles/428194-iot- connected-lighting-commercial-buildings.htm By Special GuestAlex Pop, Alex Pop is a writer on behalf of The Window Experts December 20, 2016 Smart lighting allows individuals to control lights in imaginative ways, and use them as valuable information points for collecting and sharing information about one’s facilities. With smart lighting poised to revolutionize both the lighting and networking industries, some business owners are finding it a boon, while others are still finding it complicated and are, understandably, resistant to change.
  • 10. Let There be Light One need only look at Cisco’s innovation center to find that the future of commercial smart lighting is already here. The Berlin-based, 100 person office has no light switches; instead, over 5,000 sensors control lighting and climate - feeding this data into Cisco’s central IT systems - where the company can do some pretty cool things with it. Smart Lighting: A Boon With all the lights in the building connected to motion sensors, the company is harvesting data about its 13,000 square foot facility through lights connected to motion sensors. The ceiling panels respond to network commands for on/off, brightness, color, and color temperature. Cisco claims these modern improvements have helped curtail costs as they only turn on when they need to be in use. They also help to highlight the high-traffic areas of the building, offering data on building occupancy, while creating a more ergonomic work environment for its workers, putting to use low-traffic zones, while minimizing congestion in other areas. Cisco is leading by example; LEDs Magazine finds that the hardware and telecom company has already implemented IoT connected lighting in its San Jose headquarters and regional center in Toronto. Its UK headquarters in London will soon follow, while the Berlin office will double the amount of sensors from 5,000 to 10,000 (Source). Smart Lighting: A Bane Meanwhile, individuals and business owners may be asking themselves what all the hoopla is about. For residents and small businesses who may not have the electrical wiring and networking know-how to replace one’s existing light bulbs - and run the complex APIs necessary to link smart lights to other “smart systems” of the house - the feat can seem daunting and disadvantageous. A funny tweet managed to capture the frustration of going from light switches to WiFi controlled light switches (Source). Cisco is a global company with individuals talented enough to implement these Power over Ethernet solutions; the rest of us still need to play catch up. It’s safe to say that unless you, the business owner or manager, have a large, 10,000 square foot facility, then you don’t need to shell out the upfront costs that will replace your dumb lights with smart ones. Similarly, you may not be ready to implement these changes if you do nothing with the data these motion sensor activated lights collect. Final Thoughts Smart lighting is currently a multi-billion dollar market, with applications in residential, office, shop, hospitality, industrial, outdoor, and architectural (Source). One Harvard chief, heavily into research and development claims that the entire lighting industry supply chain needs to get on board with the IoT and advanced lighting controls or be left behind (Source). One thing is for sure, however: more money will be placed into lighting controls and connected bulbs as part of a smart-home or smart-business. 3D Printed Trees Harvest Energy From Sun, Wind, & Temperature
  • 11. Source URL: https://cleantechnica.com/2016/12/17/3d-printed-trees-harvest-energy- sun-wind-temperature/ December 17th, 2016 by Steve Hanley Originally published on SolarLove Can a 3D printed solar tree capture energy from the sun? Yes, say researchers at the VTT Technical Research Centre of Finland. Not only do these little powerhouses make electricity from the sun, they also harvest energy from the wind and changes in temperature. VTT is the largest multi-technological applied research organization in northern Europe. It is part of the Finnish Ministry of Employment and Economy. The tiny leaves are made of 3D printed organic solar cells. They react to sunlight to make enough electricity to power a cell phone or other small device. The flexible cells also make electricity when they vibrate, which happens when the wind blows or changes in temperature occur. The cells not only make electricity but can store it as well. The “trunk” of the tree is manufactured from the byproducts created when real trees are harvested and made into lumber, so the trees even smell like real wood. The tiny trees can be used outdoors or indoors. The more “leaves” the solar tree has, the more power it generates. Each “leaf” is just 0.2 millimeters thick and consists of electrodes and polymer layers. The engineers at VTT actually made them look like real leaves — well, sort of, if you squint a little and let your imagination roam free. VTT claims 200 of its leaves are good for 3.2 amperes of electricity. It they are placed on an outdoor location, one square meter of leaves can generate 10.4 watts in direct sunshine. Each “leaf” has its own micro- converter built in. The 3D printed leaves have a useful life of 2 to 3 years. VTT says they can be fully recyclable so new ones can be produced with old materials. Thanks to their roll-to-roll manufacturing method, they can produce up to 100 meters of leaf rolls per minute.
  • 12. Innovative thinking about solar power is taking place all around the world. In India, researchers have unveiled asolar power treethey claim can produce 5 kilowatts of electricity while using only 4 square feet of land. For areas where open land is at a premium, the solar trees could produce significant energy in far less space than a conventional solar panel installation would require. Creative people are finding new ways to harvest the free power of sunlight every day.
