OverviewEconomic assessment of StEnSeaDevelopment historyPhysical principlePotential installation sitesMedia coverage
StEnSea is a modular high capacity energy storage technology. It''s profitability depends on installed units (concrete hollows) per facility (causing scale effects), on the realized arbitrages on the energy market and it depends on the operating hours per year. As well as on the investment and operation cost. In the following chart the relevant economic parameters for an economic assessment are pictured. About 800 to 1000 full operation cycles per annum are required.
