Energy storage will be essential for grid stability as an increasing amount of intermittent renewable energy (such as offshore wind or solar) is brought on-line. Currently accepted storage solutions are limited by opportunity (pumped hydro) or by limitations on strategic materials such as vanadium, cobalt and lithium. The ECO system does not suffer from these limitations and it is scalable into the gigawatt-hour ange using an extrapolation of available offshore technology at a cost low enough to be financially viable using just arbitrage on the daily retail energy market using any combination of wind and solar power. Beyond this, the system has the potential to scale up to provide strategic levels of grid storage for longer averaging periods. This paper will present the technical design of an efficient and viable offshore compressed air energy system.
