Method of energy storage and power generationJun Yao
The present invention is a method of combination of hydraulic power generation and floating-body power generation, which could be applied directly into current energy storage system, or could be applied as an independent power generation unit which could directly generate power to grid or store in electrical batteries.
It works well as weather-proof solutions where there is seasonal water flow shortage or during drought disaster. Moreover, it could be a robust backup during routine maintenances or malfunction of existing system.
This robust system could be built on the places where there are liquid flow available and elevation differences preferred.
Moreover, investor could use retired carriers which transported crude, oil products or LNG as oil-storage tanks when they generate power profits.

This document discusses alternative energy sources that could help power an offshore platform in Australia. It evaluates wind (horizontal and vertical axis turbines), wave (Pelamis, PowerBuoy, Wave Dragon devices), and solar (SolarBeam dishes and SunPower photovoltaic cells) technologies.

"Pony Express" electrification of long haul trucks using tractor swappingRoger Bedell
Roger Bedell of Furrer+Frey Opbrid proposes a tractor swapping model to electrify long-haul trucks using automated high power charging stations. This "Pony Express" model involves trucks arriving with low battery charges and swapping fully charged tractor units in under 3 minutes, allowing trucks to continue trips without lengthy charging stops. The model requires 400 kWh battery packs per tractor that can charge at 400 kW in under an hour between swaps. It could save up to €84,240 per year in fuel costs compared to diesel trucks and support electrifying freight transport to reduce emissions. Potential challenges include traffic delays and coordinating charger and tractor availability but the system may be feasible with proper logistics software.

The document discusses renewable energy experiences in the Canary Islands and their potential application elsewhere. It makes three key points:
1) The outermost regions (ORs) of Europe, including the Canary Islands, are ideal test platforms for developing and demonstrating renewable energy technologies due to their isolated systems and natural resources. This can benefit both other island and continental regions.
2) The Canary Islands in particular have abundant wind and solar resources and are fully committed to innovative energy technologies. They are deploying specialized technology parks and projects to maximize renewable energy penetration and transfer technologies to developing countries.

The document discusses research into optimizing the size and placement of battery storage systems in high voltage grids to better integrate renewable energy sources. The research aims to increase grid stability while reducing costs by using batteries to store excess renewable energy and supply power when renewable output is low. Linear programming is used to model the transmission grid and determine the optimal battery deployment to minimize generation and curtailment costs subject to operational constraints. Test cases on modified IEEE networks show storage can significantly reduce renewable curtailment and relieve transmission line congestion.

Pressure buffering hydropower introduction, Bogorodsky Power Co.Andrew Bogorodsky
The document describes a new type of hydropower plant called pressure buffering hydropower. It utilizes buoys in the ocean that are pushed up and down by wave motion, which pumps water through pipes to a storage reservoir located above the buoys. The pressurized water is then released through turbines to generate electricity. This design aims to provide stable renewable energy production while being scalable and able to operate without electricity in seawater. The document outlines the market opportunity and competitive advantages of this technology over other renewable energy sources.

The flexibility of Alstom Grid’s high voltage solution - Think Grid n°9Joël Devautour
Ships produce air pollution that is thousands of times dirtier than vehicle emissions. To reduce this, the EU requires ships to use lower-sulfur fuel by 2020 in European waters. An alternative is for docked ships to shut off their engines and receive power from the electrical grid via heavy cables, eliminating emissions and saving fuel costs. However, this "cold ironing" requires infrastructure investments and standardization, as ships use different voltages and frequencies. Alstom Grid developed a modular high-voltage shore connection solution to address these challenges.
IRJET- Transmission of Ac Power from Offshore to Onshore by using Low Frequen...IRJET Journal
This document discusses the transmission of AC power from offshore wind farms to onshore grids using low frequency AC transmission. Some key points:
1) Offshore wind farms generate power at medium voltage DC which is converted to low frequency AC (e.g. 20Hz) using cycloconverters for transmission through undersea cables.
2) At the receiving end, the low frequency AC is converted back to standard grid frequency AC using phase shift transformers before connecting to the onshore grid.
3) Low frequency AC transmission allows use of the same undersea cable designs as used for standard frequency but increases transmission capacity and distance. It provides an alternative to HVAC and HVDC transmission for medium length offshore connections.
Excipio Energy offshore renewables 2016Roy Robinson
Excipio Energy aims to harness offshore renewable energy, starting with steady ocean currents in the Gulf of Mexico using existing oil and gas infrastructure. Its mission is to make offshore renewable energy the most profitable, safe and reliable global energy source. It plans to initially generate power from ocean currents and later expand to technologies like offshore wind, waves and OTEC. Excipio believes offshore renewable platforms can serve as bases for aquaculture and research while avoiding many risks associated with oil and gas extraction.
There are the following global challenges:
• lack of energy
• lack of fresh water
• environmental problem
• saving the climate and life on the planet
The existing technology does not allow to avoid the potential disaster in 2050-2100. Suggested technology (Air Hydro Electric Station, Artificial Hydro Power) is perhaps the only one way that allows to avoid this.
Water Cycle is the most powerful process in Nature – about 1/4 of Sun’s Energy. Since the annual precipitation is about 1 m of rainfall, it matches a huge power ~ 800 TW that is more than 60 times greater than all the current needs of humanity and more than 400 times greater than all electrical power stations.
Why the usual Hydro power gives so little from Water Cycle power? Because the flow of all rivers is 11 times less than all precipitation and all rivers power is 200 times less than Cloud Power.
How to avoid this power loss?
• Collect water in place where it condenses really, i.e. directly in clouds
• Use all possible hydro power head in any place of land or ocean
We suggest the technology for realization this idea – Air HES, that allows to get water directly from clouds (by using a fog collector technology) in order to create artificial Hydro Power anywhere worldwide.
Major trend is the transition to renewable energy sources. It then becomes clear that resources are only sufficient for sun and (possibly) wind. Traditional hydro power does not have enough resources. However, the use of cloud energy changes this assessment.
Principally it results from economics. All three methods of conversion (PV, wind, clouds) are the same order of magnitude of the energy density (~ 100 W/m2) , but only for Air HES all this energy with virtually no loss can be merged into one point (pipe/turbine), making part of the proportional m2 far cheaper than other alternatives. This implies ROI > 1000% that allows quickly rebuild the energetics and successfully pass the collapse of energy & climate in 2050.
This document summarizes a presentation on increasing the energy, power, and efficiency of ultracapacitors. It describes the need for energy storage and harvesting applications without batteries.

The document analyzes converting diesel rubber-tired gantry cranes (RTGs) at the Durban Container Terminal in South Africa to electric RTGs (E-RTGs) to reduce costs and environmental impacts. RTGs currently use diesel which is expensive and polluting. E-RTGs can reduce fuel and maintenance costs by 70% and reduce emissions by 60-80% compared to diesel RTGs. The document discusses three methods for converting RTGs to electric systems: bus bar systems, overhead conductor systems, and cable reel systems. It concludes that converting to E-RTGs would help Durban Container Terminal lower costs, improve air quality, reduce emissions in line with international standards, and make the terminal more environment

It describes several technologies that could help drive this transition, including thermal energy storage systems, container-based energy storage for rail transportation of electricity, and wave energy generation. The key is developing market incentives and financial models to make non-carbon technologies economically appealing to users and spur a large-scale paradigm shift away from carbon.
The Long-Term Energy Storage Conundrum and its Impact on the Clean Energy Tra...BXD
A key factor holding back the transition from CO2 intensive fossil fuel based power generation to clean (green) energy-based sustainable production is that of how to store energy that is essentially
intermittently produced.
In an exclusive interview with BXD, Mark Howitt, CTO of Manchester, UK, based Storelectric, discusses the current state of the clean energy transition worldwide, the need for long-duration energy storage, the place for hydrogen in national grids, and a way to eliminate the renewable
energy intermittency issue, reduce energy wastage and increase efficiency.
Hydrogen is perfect for the gas grid: up to 10-15% mix with natural gas can be achieved with minimal network modifications and upgrades. Beyond that, it's inappropriate until you hit 100%. That's because a mix is only useful where it's being burned. But the applications for which hydrogen is best suited require 100% purity – applications such as fuel cells, transportation, fuel and chemical synthesis, iron smelting, steel production, and so on.

The key is developing market incentives and financial models to make non-carbon technologies economically appealing to users and spur a large-scale paradigm shift away from carbon.
The Long-Term Energy Storage Conundrum and its Impact on the Clean Energy Tra...BXD
A key factor holding back the transition from CO2 intensive fossil fuel based power generation to clean (green) energy-based sustainable production is that of how to store energy that is essentially
intermittently produced.
In an exclusive interview with BXD, Mark Howitt, CTO of Manchester, UK, based Storelectric, discusses the current state of the clean energy transition worldwide, the need for long-duration energy storage, the place for hydrogen in national grids, and a way to eliminate the renewable
energy intermittency issue, reduce energy wastage and increase efficiency.
Hydrogen is perfect for the gas grid: up to 10-15% mix with natural gas can be achieved with minimal network modifications and upgrades. Beyond that, it's inappropriate until you hit 100%. That's because a mix is only useful where it's being burned. But the applications for which hydrogen is best suited require 100% purity – applications such as fuel cells, transportation, fuel and chemical synthesis, iron smelting, steel production, and so on.
This document discusses various desalination processes and their energy requirements and costs. It provides details on membrane-based processes like forward osmosis, reverse osmosis, and membrane distillation. Forward osmosis uses osmotic pressure to purify water and has potential applications in water treatment, energy production, and life sciences. The document outlines several pilot projects using forward osmosis and membrane distillation technologies and discusses the benefits and challenges of these innovative approaches to desalination.
This document discusses the history and types of batteries. It begins with defining batteries and describing their invention by Volta in 1800. It then discusses the increasing demand for batteries to power electronics and electric vehicles. The document outlines several recent advances in batteries, including sodium-ion and solid-state designs that improve safety. It concludes that continued research in nanoscience and new materials could enable breakthroughs in sustainable battery technologies.
Exhibit C HSH - Operations in a Desert Environment-2015.pdfJustin Sutton
The Hydrogen Super Highway elevated rail system is ideally suited for operations in harsh desert conditions. Compared to traditional steel wheel rail infrastructure, the HSH will be more reliable and have a longer and much broader value and return on investment. The HSH enables the reconstitution of arid land into useable farm land.
The document discusses the construction of a wave energy converter in Greece. It proposes building an overtopping breakwater in the harbor of Heraklion, Crete that would serve the dual purpose of protecting the harbor from waves while also producing electricity from wave energy. The breakwater would work by exploiting running-up waves that overtop into a reservoir and are then returned to the ocean through low-head turbines to generate an estimated 290 MWh of electricity per year, enough to power 83 households. The design is intended to reduce costs compared to conventional breakwaters while helping Greece achieve its renewable energy goals.
The document describes a new e-propulsion system for boats developed by Innovanautic. The system uses electric motors powered by batteries and/or generators for propulsion.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Teaser OGRES
1. Who we are?
Sink Float Solutions is a European company, created in 2014 by Christophe Stevens, inventor,
in order to promote the development of a new energy storage system (OGRES) to solve the
intermittency problem or renewable energies with an economically viable cost.
Since 2013, several persons were involved in the project and contributed to increase its
maturity (technical experts and funding). After several years of research, conceptualization
and patents applications, the technology is ready for a demonstration.
Ocean Gravitational
Energy Storage (OGRES)
Why is it important to reduce the cost of energy storage?
In 2015, several storage solutions exist, but they are still too expensive to be combined to large
scale wind or solar farms. For that reason, when there is no wind or no sun, the electricity
consumer is usually served by thermal power stations.
Those power plants usually burn fossil fuels (gas, coal), and then the development of
renewable energies contribute to global warming.
Why the conventional storage solutions are and will remain expensive?
Conventional storage solutions tackle economical
and technological barriers.
The cost of batteries depend on the cost of raw
materials (lead, lithium, etc), and their life time is
limited (3 to 10 years). The cost of pumped-
storage hydroelectricity, depend of the
topographic environment, and the best locations
are already installed. The other solutions are
even more expensive (flywheel, compressed air,
hydrogen, capacitors)
Those economical barriers can be demonstrated
by using physical and chemical laws.

2. The OGRES energy storage technology solves the intermittency issue
of wind and solar farms at an unbeatable price.
We offer a solution 5 to 20 times cheaper than the most competitive conventional
storage systems (batteries and pumped-storage hydroelectricity).
This technology works like a big battery, settled near the cosat line and connected to the
grid with a submarine electric cable.
Simplicity: our technology uses the gravitational potential energy by using important
elevation differences between the sea surface and the seabed.
During the reloading phase, the system raises concrete weights one by one with a simple
lifting hoist cable device with an electric motor on a barge. And during the energy production
stage, the system descends the weights one by one and run an electric generator.
The system is reloaded, the weights hang
near the sea surface.
The system is unloaded, the weights are
on the seabed.
Generator mode,
When there is no wind,
the system releases the
weights and produces
electricity for the
consumer.
Motor mode,
When there is a lot of
wind, the excess of
electricity is used to
reload the system, the
hoist raises the weights
one by one.

3. By taking into account the floats, the anchoring cables, the barge, the hoist lifting system
with a 13,000 feet cable, the control system and the submarine power cable, the total
investment cost will vary from $ 30 to $ 90 /kWh depending on the location (distance to
shore, depth), storage time (quantity of weight for each barge), and the maturity level of
the system (prototype vs. Industrial development).
A solution robust, easy and fast to implement because using well known
components already existing (industrial maturity for many decades). The suppliers can offer
a warranty (10 to 20 years lifespan). The material availability is unlimited and generate poor
contamination: mainly steel cables, cement, iron, reinforced concrete and 10 kg of PVC for
each ton of floating capacity, which correspond lifting bag high quality standard required
notably by oil and gas offshore industry.
An economical advantage easy
to demonstrate:
Like pumped storage hydroelectricity
(PSH), our system uses the
gravitational potential energy, but
instead of transferring water between
two reservoirs with an average
elevation difference of 600 feet, we
propose to transfer solid weights
(concrete) by using 6,000 to 25,000
feet elevation differences (available in
the Ocean).
By using such elevation differences, it
is possible to store the same quantity
of energy in one ton of concrete than
in one ton of battery.
Example: With 13,000 feet depth (which is the average depth of the sea), it is possible to
store 10 kWh with one ton of concrete (less than $ 100). This figure can be easily
demonstrated with the potential energy formula (Epot = MxGxH). By comparison, the most
competitive battery (Tesla) will be sold for $ 3500 for the same energy storage capacity.
In other words, for 10 kWh of storage capacity, the concrete weight will be 30 times
cheaper and with a lifespan at least 2 times higher.

4. Viable also for small scale barges: Despite some fixed cost respect to power (submarine power
cable implementation and ROV operations), our system is economicaly viable from 1 to 10 MW
according to location characteristics. In the most favorable situation, it is equivalent of a diesel
generator. In the worst situation (distance > 250 km) our system is competitive for power higher
than 20 MW. est compétitif pour des puissances de 20 MW et au delà, which is much lower than a
thermal power plant (gas, coal).
Assumption: The cost include investment, lifespan, O&M. Wind: investment ) 1 million dollar / MWp,
capacity factor 25%, Storage: capacity 24 hours, barge power = 0,7x nameplate wind farm power,
energy losses due to storage = 20%, barge investment = 0,5 million dollar / MWp, weights = 30
$/kWh and 10 years lifetime, O&M < 5% capital/yr. Submarine electric cable: investment = 160
k$/mile + 5 k$/mile/MW.

10 miles
4 MWp = 2 wind turbines
This example shows that our storage system, combined with wind turbine farms can serve the
consumer with a competitive price, and without using the public grid, including for
small markets (2 wind turbines for 1,000 inhabitants), and for important distances between
the wind farme and the storage barges. Islands simulations show even more competitive
situation (for examble: Hawaii, Reunion island, Dominican Republic, etc.)

5. Total flexibility
The ratio capacity/power (MWh/MW) can be adapted to every need: from 3 hours (nuclear
power) to 12 hours (solar) and to 24, 48 hours (wind turbines). The « power » components
(the barge, MW) and the «energy storage capacity » (the weights, MWh) are completely
separated. .The number of weights for each barge, can be adapted to each situation and even
be modified after the first investment. The system can also be sold and relocated somewhere
else to adapt to the market evolutions, because the transport cost (towing) and electric cable
implementation are low.
The deployment potential is unlimited, unless the eligible sites for pumped-storage
hydroelectricity.
An outstanding energy efficiency (70 to 90%), because the energy losses are low
(hydrodynamic friction due to the vertical movement of weights) => 3 to 15 miles/hour.
Many technical solutions will make possible to operate the system even with
rough sea conditions and without increasing the costs.
The weights hanging and releasing operations
can be done by using smooth lanyards* for each
phase: generator/motor mode and up/down
storage position.
This allows to use ROV (conventional
submarine robot), also for hundreds of tons
weights.

6. The economical performance presented in this document, was calculated for low power
barge (1 MWp) and small weights (50 tons). Important scale economies are possible by using
bigger weights and barge because their wind and flow exposure (surface) increase slower
than the storage capacity (volume).
Important economies can also be done by accepting operating rates below 100%, for
example, when the weather conditions are exceptional. In such situations, backup should be
available in order to supply the consumer. Diesel generators with a low capacity factor (1 to
5%) can be used with a very small economical and environmental impact. An economical
calculation could be done for each situation.

In upper position, the weights and their main floats are stored several tens of meters
beneath the sea surface. At such a depth, the current flow generated by the wind is strongly
reduced. Thus it is possible to reduce the cost of anchoring cable for which length
(proportional to depth) is expensive.

The main float will follow the weights during
the descent phase, in order to avoid to rise
on the surface and be in contact with the
wind and the surface current flow. Its volume
(and then its floating capacity) will decrease
expontentially with the depth, with the
pressure increasing.
Pression x Volume = Constant
40 meters: 72 Psi => 50 m3 (100%)
400 meters: 495 Psi => 6 m3 (12%)
4000 meters: 5800 Psi => 0,1 m3 (1%)
With 4000 meters depth, and a 8 km/h
speed (5mph), a 50 tons weight can generate
or absorb 1 MegaWatt of power during 30
minutes. Each weight of 50 tons can store
500 kWh of energy.
Halfway, (after 15 minutes) the two hooks will cross, and guide
systems including conventional submarine robotics will avoid
giratory movements and improve the accuracy of the
dropping/hanging operations.
Numerous variants, not presented in this document, will ease
the control of horizontal and vertical weights movements, the
position of the barge, will improve the hydrodynamic design by
reducing the cost and improving the lifespan, Automation et
each phase, maintenance cost improvements, ensure a constant
or variable power as a function of the need in real time.

Billions dollars markets
Despite their high cost (> 200 $/kWh), their poor energy efficiency (65 to 70%) et their
environmental impact, pumped-storage hydroelectricity (PSH) is the only solution to have
been developed on an industrial scale for transmission system grid. More than 120 GWe PSH
were implemented in the world (tens of billions of dollars investment), often for being
combined to nuclear power plants. However their cost remain too high for them to be
developed together with renewable intermitent energies (solar and wind) because those
require much more than 3 hours of storage capacity.
The huge cost reduction of our storage system make 100% renewable energy mixes can be
competitive in numerous markets.
The market share will not be taken only on other conventional storage solutions (PHS,
batteries), but also on thermal power plants (coal, gas).
Example for a 100 MWp wind turbine farm
For a 100 MWp wind turbine farm, with a 25% capacity factor (220 GWh/year) and with a 24
hours storage capacity, and a storage (barge) power equivalent to 70% of the nameplate wind
farm, 70 MW of barge and 600 MWh of weights would be necessary, which represent a 75
millions dollars turnover for the storage solution (barge and weights) and 120 millions dollars
for the wind turbines.
Example for the german market
In 2014, in the world, 140 Gwe of renewable new capacities were implemented, which
represent 400 MW every day. In a country like Germany (less than 3% of electricity world
market), where renewable share of electricity mix is reaching a critical point regarding the
intermittency challenge, le development of OGRES storage technology would generate a 7
billions dollars turnover every year.

9. Stage 1 : To guarantee an exclusivity to our future sharehoder
Since 2014, several patent were applied for regarding all variants allowing to use the
principle of OGRES. The first conclusions of the search reports confirm the results of our
anteriority studies, by considering as new all the claims. Complementary patent applications
were carried out regarding technical solutions allowing to improve the costs.
Stage 2: To provide proofs to our future customers.
Because of the huge cost reduction by comparison with conventional solutions and despite
the simplicity of OGRES, it is essential to do a demonstration. The next step is ongoing:
Assembling a full prototype big enough to validate performance criteria with 2 main
objectives:
1) Cost validation: Components and assembly (proof = invoices)
2) Working validation: including with rough sea conditions.
(proof = video of several cycles with incrasing rough sea conditions and performance
records: weight changing dead time, energy efficiency, mechanical constraints, etc)
Stage 3: energy transition acceleration
OGRES technology marketing can be done by selling patent rights and/or royalties on
geographic perimeters and/or project wind/solar farms. Or by delivering turnkey solutions
(barges, weights) to customer.
The industrialization stage can be fast because all components are standards and can be
manufactured by existing industrial plants. Assembly can be done by shipbuliding facilities
in many places. Each component (gear reducer, motor/generator, ROV, lifting bags and
other floating omponents, polyester or steel cables, etc) are available on brochure by many
suppliers and offer an important reliability since they are used for many decades.
Page 9-10 PublicSink Float Solutions - All Rights Reserved - 2016
In order to validate the operations in rough
sea conditions, the prototypes will have a
minimal size but will make possible to
overcome scale extrapolation calculation
and thus ease the proof understanding.
Complementary trials will be carried out
with high capacity lanyards and rental
material (high capacity barges, heavy duty
conventional ROV’s) in order to validate the
critical functions with high capacity scale (>
50 MWe/barge) and by using standard
components certified for the grid.
