BaroMar selects Jacobs for energy storage pilot
BaroMar has selected Jacobs to develop the preliminary design for a first-of-its-kind underwater large-scale, long-duration energy storage pilot project off the coast of Cyprus.
Utilising existing mature technology in power, energy, and marine engineering, combined with the hydrostatic pressure of the seawater, the system aims to achieve relatively low installation costs and the lowest levelized cost of storage (LCOS), with a goal of round-trip efficiency of up to 70 per cent.
The technology is claimed to address the challenges of relying on intermittent renewable sources and the capital costs of supporting infrastructure.
“This project requires extensive geophysical, geotechnical and bathymetric surveying, investigation, feasibility studying and permitting for tank installation at deep depths for onshore mechanical and electrical equipment needs,” Jacobs vice president Fiachra Ó Cléirigh said in a statement.
The basis of the 4MWh pilot project relies on storing compressed air in large rigid tanks that are ballasted on the seabed. The tanks are designed to resist loads imposed by the marine environment as well as the compressed air and hydrostatic water pressure, during installation and operational conditions.
