Funding has been awarded as part of the Longer Duration Energy Storage (LODES) Competition. The competition recognises the transition to increasing wind generated renewable energy, which presents growing opportunities for storage systems that support a secure, flexible, and reliable electrical power supply.

The PowerBundle concept will combine FLASC’s proprietary Hydro-Pneumatic Energy Storage (HPES) technology and Subsea 7’s proven subsea pipeline bundle technology, resulting in a scalable and robust offshore energy storage solution.

Liam Macintrye, Subsea 7 Strategic Director – Energy Transition, said: “We are very pleased to have our innovative solution recognised by BEIS, as it builds on our proactive participation in the energy transition. The development of energy storage solutions plays a crucial role in the future of intermittent renewable power sources, and the interconnectivity of our energy systems. We believe such systems will not only unlock additional grid connected offshore wind, but it could also play a valuable role in decarbonising oil and gas assets.”

Daniel Buhagiar, Co-Founder and CEO of FLASC B.V., said: “This funding support from UK BEIS provides a major boost to our technology development initiatives, and we are extremely proud to have been selected in this pioneering and highly-competitive funding programme; one of the first specifically targeting Longer Duration Energy Storage. Beyond the financial support, this also confirms our view that offshore energy storage technologies have a key place in the energy transition, working alongside onshore solutions towards a cleaner and more robust energy system.”

The competition will be delivered through two phases. In phase 1, projects will be expected to mobilise their proposed technologies to prepare for potential deployment on the UK energy system. Successful proposals will receive further funding for phase 2, to build and test a grid connected full-system demonstrator of the proposed technology and qualify it through testing. A formal stage gate review will take place between phase 1 and phase 2 of the competition. Work has already commenced for phase 1.

Greg Hands, Energy & Climate Change Minister, said: “Driving forward energy storage technologies will be vital in our transition towards cheap, clean, and secure renewable energy.

“It will allow us to extract the full benefit from our home-grown renewable energy sources, drive down costs and end our reliance on volatile and expensive fossil fuels. Through this competition we are making sure the country’s most innovative scientists and thinkers have our backing to make this ambition a reality.”
