Subsea + FLASC among energy storage competition winners

24 February 2022

Subsea 7 and technology partner FLASC have won a UK Government grant for £471,760 to develop an offshore energy storage system. Their joint submission was one of the winners in the UK Government’s £6.7mn “Longer Duration Energy Storage” competition. They were named February 24. 

As wind-generated renewable energy grows, so will the need for systems that support a secure, flexible and reliable electrical power supply.

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

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

The competition has two phases. First, projects will ready their proposed technologies to prepare for potential use on the UK energy system. Successful proposals will then receive further funding for phase 2.

Subsea 7 said systems such as the one under development will not only unlock additional grid connected offshore wind, but could also play a valuable role in decarbonising oil and gas assets. They play “a crucial role in the future of intermittent renewable power sources.”
