Dismounted Soldier
System (DSS) power issues
• Soldiers carry too much
• Batteries contribution significant
• Future capability could increase
power demand
– more data = more power
• Need to reduce battery burden

What we don’t want
• Energy harvesting proposals that don’t
– improve state of the art
– compete with batteries over 2-3 day missions
– make reasonable assumptions for resource
• Battery or fuel cell proposals that don’t
– exceed COTS
– or utilise COTS systems in a novel way

Expected bid technical information
• Show an awareness of state of the art and
how the proposal claims to improve on this:
– Novel improved technology
– Novel use of a COTS technology
– Estimated performance
• Evidence or logic for estimates if possible
– Clearly defined deliverables

activities both foreign and
domestic consume significant
quantities of energy

• Well understood properties
• High energy density
• Relatively safe in an
operational environment
• Single source of energy
reduces logistical burden

Risks

– Reduced re-supply missions
• Reduces cost and exposure to
harm
– Increased autonomy of force

The Essential Role of Flexibility in our Energy Future

EMEX

It is widely recognised that increasing flexibility is key for the reliable operation of future power systems with very high penetration levels of variable renewable energy sources. The starting point of this webinar is the understanding of the flexibility requirements for enabling the transition to such power systems. A comprehensive assessment of the complete spectrum of flexibility options will be provided, identifying key barriers for their deployment. This analysis follows a study carried out by Ecofys for the European Copper Institute. http://www.leonardo-energy.org/webinar/can-we-achieve-100-renewables-flexibility-options-electricity-system

The Webinar presents the results of a research project on flexibility in the German power sector. It analyses the flexibility demand with a rising share of RES-E and compares different flexibility options. The project consists of a model-based scenario analysis for 2020, 2030 and 2050 and applies the electricity system model PowerFlex together with a European network model to analyze import and export as a flexibility option. Flexibility becomes an issue only in the scenario 2030 with 60 % RES-E. In 2020 additional flexibility can increase efficiency, but is not essential to run the system or to integrate RES-E. http://www.leonardo-energy.org/webinar/how-demand-flexibility-will-develop-german-power-system

Webinar recording at https://youtu.be/2A-aVb6OHTE The coordination between planners and operators of coupled energy systems will allow the further integration of renewable energy sources in the electricity network by storing energy in fuel form over long periods of time using power-to-gas, the recovery and more efficient use of heat, and the decarbonization of industrial processes and transportation modes that can’t be electrified. Energy networks, such as electricity grids and natural gas pipeline networks, have traditionally been planned and operated independently. In order to enhance the integration and coordination of different energy networks, they must be planned and operated in coupled ways. Different energy networks have historically been and are still modelled by different tools. In this presentation we will discuss the need model coupled energy systems in a single framework and we will introduce encoord’s Scenario Analysis Interface for Energy Systems (SAInt), a software application to model, plan, and operate coupled energy networks.

VIETNAM – MOIT PROPOSES EXTENSION OF CURRENT FiT RATE FOR WIND POWER PROJECTS

Dr. Oliver Massmann

More and more countries world-wide are targeting high shares of wind and solar photovoltaics in their electricity mix. To integrate high shares of these variable renewable energy sources, the electricity system needs to become more flexible in order to balance supply and demand at all times. The webinar will discuss key design features of future electricity markets, including incentives for more flexible fossil-fuel based and renewable-based power generation, modifications to the design of electricity markets, incentives for more flexible demand, and storage options.

DC4Cities: Following the Patterns of Renewable Power in a Smart City

DC4Cities Project: Environmentally Sustainable Data Centre for Smart Cities

The future urban energy systems can move to directions in which bioenergy will play a key role, for example as fuel for space heating, for (back-up) electricity generation, and for mobility (biofuels). A competitive deployment of bioenergy requires sufficient availability of biomass and acceptable costs. As result of the uncertainty in the price developments of bioenergy, the view on the future is uncertain as well. Also in the recent study "Urban electrification - impact of electrification of urban infrastructure on costs and carbon footprint" results were strongly dependent on assumptions on the availability and costs for bioenergy. In this interactive workshop, we sketched the landscape of bioenergy in relation to the urban energy system and develop a joint view on bioenergy availability and cost. The workshop covered the following aspects: * Which types of bioenergy carriers are most suitable in the urban energy system? * What could be the availability of those bioenergy carriers? * What would be typical costs per type of resource and what are the drivers and uncertainties? * What is the role of policy in the cost development of bioenergy and how can the cost gap be bridged?

V2X is an umbrella term to explain the use of Electric Vehicle (EV) batteries to provide energy services and derive additional value from the battery asset during times of non-use. V2X services aim to generate revenue from the battery asset through dynamic or bi-directional charge control to provide benefits to the electric grid or to reduce/flatten/shift peak energy consumption of buildings and can be classified in the following operating modes: · Vehicle-to-Grid (V2G): Using an EV battery to interact with/provide value to the electric grid · Vehicle-to Building (V2B): Operating EV batteries to optimize building energy consumption · Vehicle-to-Home (V2H): Optimizing home energy consumption or as emergency back-up power · Vehicle-to-Load (V2L): Any other instance of an EV battery providing energy to a load
