2 UK Energy Generation Mix UK Electricity Generation 2014 Source: UK Energy Statistics, 2014 & Q ( 3 October 2015 Potential Future UK Energy Generation Changes to electricity demand, demand profile and generation mix, for example.. Higher electricity demand (Carbon Plan: up by around 30% to 60% by 2050) and higher levels of 600 renewable, more intermittent electricity expected Electricity imports 500 TWh / year Non-thermal renewable generation Nuclear power Carbon Capture Storage (CCS) Unabated thermal generation Domestic demand Source: Higher renewables; more energy efficiency 2050 pathway, The Carbon Plan: Delivering our low carbon Future, 2011 Such changes have implications for overall operation of the electricity system and the secure, efficient transfer of electricity from generation to point of use. 4 Trilateral Energy Storage Workshop October

3 Energy Storage Policy Issues A DECC report Electricity System: Assessment of Future Challenges, published August 2012, concluded that: increasingly, technologies that can be used to help balance the supply and demand of electricity (demand side response (DSR), electricity storage and interconnection) and smarter networks are likely to be required to help match the supply and demand of electricity efficiently and cost-effectively under the changing generation and demand profiles. DECC believes that the extent of deployment of storage will depend on the composition of future electricity systems both supply and demand as well as the cost and availability of storage and the other balancing technologies - including DSR, interconnection and more dynamic use of electricity networks. Challenge is expected to arise beyond 2020: There will be different types of generation in different places.as well as increased demand and different load patterns This will pose significant challenges to networks and the balancing of the system. 5 October 2015 UK Low Carbon Innovation Policy The Low Carbon Innovation Coordination Group (LCICG), which includes the Department of Energy and Climate Change and the other major publicsector backed organisations that invest in low carbon technology innovation, published a Strategic Framework in February 2014 ( ork/overview/ ), which prioritises future innovation needs in 11 key technology areas including electricity storage. Public Sector Innovation Support Energy storage has been a key focus for low carbon innovation support in the UK in the last few years. The UK Department of Energy and Climate Change, the UK Research Councils and the Energy Technologies Institute have committed more than 65m ( 90m) to energy storage research, development and demonstration since October

4 Aim of DECC Energy Storage Innovation Competitions: Support innovation in large-scale storage technologies Secure cost reduction Enable wider deployment of energy storage Bring the technologies closer to market DECC innovation aims: To help deliver our 2050 climate change targets and energy security objectives cost-effectively by. ensuring that the right energy innovation happens. We focus on technologies where there are clear market failures and programmes where intervention will have the greatest impact on meeting the climate change and energy objectives. DECC s Energy Storage Innovation Programme was launched in 2012: Technology Demonstration Competition: SBRI competition offering up to 17m for pre-commercial procurement of energy storage demonstration projects 4 large-scale demonstration projects underway all due for completion in 2016; Component Research & Feasibility Study Scheme: up to 3m grant funding available; 7 projects underway; all due for completion by April Energy Storage Technology Demonstration Competition Technology Title & outline of proposed energy storage demonstration project Li-ion batteries Moixa Technology Ltd : Distributed energy storage for consumer, distribution network and grid-scale needs. Install & demonstrate deployment of 0.5MW/0.5MWh of distributed storage across 250 domestic sites. Grid-connected via aggregator. Li-ion batteries, including recycled EV batteries Vanadium Redox Flow Battery EVEREST Consortium (Electric Vehicle Embedded Renewable Energy Storage and Transmission) Project to develop and demonstrate a 150kW modular battery storage solution partly using recycled batteries from electric vehicles to provide Plug-In-Vehicle and rapid charging infrastructure. Demonstrator can be charged using local renewable generation (small solar array and wind turbine) or from the grid. REDT UK Ltd: Project to build and test a 1.2MWh flow battery storage system on the Isle of Gigha (Scotland) to store surplus wind energy for use in the island s own electricity network when required. Liquid Air Energy Storage Highview Ltd and Viridor Waste Management Ltd: 5MW/12MWh liquid air demonstrator system; using waste heat to improve efficiency. The system will provide balancing services in the commercial markets (via an aggregator). 8 October

6 Other UK innovation support for storage Since 2010, Ofgem, the UK s energy markets regulator, has provided more than 100m ( 138m) to the UK DNOs through its Low Carbon Network Fund for network innovation projects which include testing energy storage in the distribution networks. 11 What next? New DECC Smart Energy team is looking into barriers to the deployment of energy storage and how we can best address them. All UK Government Departments, including DECC, are currently waiting the outcome of the HM Treasury-led Comprehensive Spending Review this will set budgets for We will know the (high level) outcome of the Spending Review in late November. Depending on the outcome of the Spending Review, we will then start developing future energy innovation programmes in detail. 12 October

7 Further Information The Good Practice Guide on Electrical Energy Storage, published December 2014, provides an overview of recent UK energy storage innovation projects and draws out good practice from these demonstration projects.
