FLASC is developing a hydro-pneumatic energy storage system tailored for offshore applications. The objective is to bridge the gap between intermittent renewable energy production and a fluctuating consumer demand. This allows, for example, large offshore wind farms to improve the quality of the power that they provide to consumer grids, and also to supply reliable power in remote offshore locations, such as oil & gas infrastructure. Energy is stored using a hydro-pneumatic liquid piston, pumping seawater to compress a fixed volume of air. Using our patented dual-chamber technology, we have optimised this process to achieve very high efficiencies, making it a commercially viable solution. It is built on established supply chains and well-proven concepts already used in the offshore oil and gas industry. FLASC has been prototyped and tested, and has received a Statement of Feasibility from DNV-GL. Our unique solution is best-suited for the offshore market, where conventional battery technologies struggle due to their short lifetime, along with safety and environmental issues. On the other hand, the FLASC technology embodies the core principles of offshore, it is: safe, reliable and cost-effective.
