FLASC B.V.

FLASC is a start-up working on non-battery energy storage for offshore applications. It is tackling a fundamental problem: the mismatch between renewable energy supply and consumer demand. Renewable energy is not stable and predictable and neither is the demand. Integrating storage with renewables can be a solution to this problem. It is the first solution tailored for co-location with offshore wind. It is based on an advanced hydro-pneumatic liquid piston concept where electricity is stored by pumping a liquid to compress a volume of air. We have now shifted to the Open-Gas Cycle technology, which embodies the latest developments in performance and energy density. No sea-water is used in this cycle. Using a patented pre-charging concept, and the marine environment itself as a natural heatsink, the compression process is optimised to achieve very high efficiencies, resulting in an offshore solution that is cost-competitive with land-based storage. With a co-located FLASC system, offshore wind farms can become an active provider of grid flexibility when using energy storage. Recent studies show that this can add 10-30% more value to the wind farm output by improving the way it is monetised. The FLASC technology is covered by international patents, received a Statement of Feasibility from DNV and recently selected for funding under the prestigious EIC Accelerator.
