enabling large-scale
offshore energy storage
Hydro-Pneumatic Liquid Piston Technology
addressing two of the biggest challenges problems opportunities in the energy industry
Temporal Mismatch

- Offshore wind generation is intermittent and can only be used when there is immediate demand
- Offshore wind developers need a suitable buffer to store energy that is otherwise wasted during periods of low demand.
Spatial Mismatch

- When the onshore grid is constrained, offshore power cannot be delivered where needed and ends up being wasted.
- Offshore wind developers need a suitable buffer to store energy and deliver it when the grid is available.
FLASC addresses client-specific Pain Points
bridging the gap for offshore wind developers
- Developers are currently exposed to wind intermittency, demand fluctuations, grid congestion and market volatility.
- A FLASC energy storage system within the windfarm introduces flexibility to the energy supply, increasing profitability which will enable a scale-up in new offshore windfarm deployments.
- FLASC is unique when compared to other offshore energy storage concepts because it is compact and less expensive, has a lower environmental impact, and can be co-located in shallower waters within the footprint of the windfarm.
