Two British firms have tucked away £8 million from a government competition to back energy storage.
Viridor Waste Management and tech firm Highview Power Storage bagged the cash to develop a technology to store air in a liquid state.
This would then be used to supply electricity at times of high demand.
Climate Change Minister Greg Barker said: “Storing energy will become increasingly important in the move towards a low carbon economy and has the potential to save the energy system over £4 billion by 2050.”
Gareth Brett, CEO of Highview Power Storage said it was a chance to commercialise a “home grown” technology. His firm has been piloting the frozen air technique in Slough.
Mr Brett said: “The collaboration with Viridor will enable Highview to showcase the technology at larger scale, harvesting waste heat from landfill gas engines and demonstrating our readiness for deployment elsewhere.”
Viridor’s Landfill Energy Director, Ian Morrish said: “With ever growing pressure on natural resources, it is essential that we develop innovative and sustainable methods to generate and store energy not only to cut down our carbon footprint but to ensure long-term energy security.”
