Onshore Applications
LONG-DURATION ENERGY STORAGE (LDES) Powered BY WATER
Engineered for harsh offshore conditions and autonomous operation, FLASC now brings its proprietary energy storage technology onshore: to inland and coastal sites with direct access to water.
WHERE FLASC FITS
Where there’s water, a new class of energy storage becomes possible
FLASC turns suitable water-connected sites and existing infrastructure into powerful opportunities for long-duration energy storage.
Lakes and Reservoirs
Natural or engineered water bodies near the grid
Ports and Coasts
Harbours and coastal industrial zones
River-Adjacent Sites
Industrial areas along major waterways
Industrial Basins
Cooling ponds, treatment facilities and engineered reservoirs
The Water Advantage
One Core Technology,
Two Deployment Environments
Water enables FLASC’s near-isothermal compression and expansion process.
From offshore waters to inland and coastal sites, FLASC applies the same hydro-pneumatic storage principle wherever suitable water access is available.
