Solihull/ Twickenham (20/07/18) – Energy SRS and partners have secured funding of £727,000 for a second phase development of gravity storage research project. The project combines the knowledge of current industry players and academics to deliver a working gravitational storage prototype.


Since its formation in 2013, Energy SRS has been working on the development of sustainable energy storage based solutions to help support the management of power system inertia.


The GENSSIS Project has received £727,000 of Grant Funding from Innovate UK, the UK’s innovation agency. As the grid continues to decarbonise with increasing renewables on the system, there is a need to have a diversity of reliable back up power. Storage technology will be the linchpin technology of the future.


The project involves five partners alongside the lead partner, Energy SRS. The project was established in 2015 and has developed the concept. Phase 1 was completed in March of 2018. The current phase 2 of the project commenced at the start of July and will prepare advanced designs to enable a 1.2 MWh prototype for testing next year.


The GENSSIS project works on a simple principle; raise a large mass using electrical power (surplus power when available) thus storing energy, and lower it when the stored energy is required to regenerate electricity. This weight is lowered under gravity, to create kinetic energy which can be converted into electricity. The theory is simple, however development, construction, testing, and commercialisation of a viable, large scale, utility, installation will require new knowledge, skills and processes.


The additional five partners UK Power Reserve Ltd, PR Marriott Drilling Ltd, Caley Offshore Systems Ltd, Bayliss Consulting Ltd, The University of Bristol have all provided knowledge and guidance to the project. This multi-disciplined industrial and academic partnership has given the project the theoretical and practical grounding to ensure phase one was successfully completed to allow phase two to begin.


Brendan McGrath, of Energy SRS said “This innovation funding will give the project the cash injection it needs to prove this is a viable technology. The UK is a world leader in the storage market and delivering new and innovative solutions will be key to unlocking its full potential. Intermittent renewables give the grid new challenges and I believe our innovation will give the system a new solution to this problem.


“I’m grateful to the project’s partners for their input in the process so far and excited to see phase two kick off. This wouldn’t be possible without Innovate UK who drive innovation in the UK.”
