2012: Technology Innovation Needs Assessment (TINA) for Electricity Networks & Storage report estimates:• 7-59GW of grid connected storage by 2050.• Energy storage innovation potential to save the

energy system > £4bn by 2050.• UK energy storage industry growth potential

estimated to reach £11.5bn by 2050.

2012: DECC report ‘Electricity System: Assessment of Future Challenges’,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”.

2013:Energy storage identified by the Government as one of the UK’s current 8 “great technologies” in which the country has world-leading research and have the potential to support UK growth.

2012: Prof Strbac and Imperial College’s work for Carbon Trust on the Role and Value of Energy Storage Systems in the UK Low Carbon Energy Future, noted that it is “essential to demonstrate and evaluate a range of storage technologies”.

UK Innovation Support for Storage

Aim of DECC Energy Storage Innovation Competitions:

• 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.
