Subsea Energy Storage

Oil and gas operations as well as the global shipping industry need to identify and implement technologies and processes to reduce or even eliminate CO₂ emissions and HSE risks. It opens the need for new, innovative subsea technologies related to the use of e-fuel as a source of energy combined with new regulations and requirements for the safe installation and operations of such systems on the seabed.

The Subsea Energy Storage System is designed to store subsea large quantity (up to 10 000m3 units with cluster carrying up to 5 units) of e-fuel such as liquid ammonia and e-methanol to either support subsea oil and gas production replacing conventional gas turbines or as a refueling station for ships, tankers, carriers as ammonia and e-methanol engines are becoming readily available.

The chemicals are stored separately in Subsea Storage Unit at ambient pressure and temperature in a compatible flexible membrane, protected and secured to the seabed by external structure. The use-specific system shall comprise also topside distribution booster, power, control and monitoring either on the platform or on a buoy/bunkering station and can be virtually installed anywhere subsea, at any water depth thanks to already qualified flexible pipes and downlines. The system qualified for 10 years can also be picked up and redeployed making it economically and environmentally sustainable

25 000m3 of liquid ammonia provides almost 100 MWh, enough to power a platform for over 2 months or powering a large number of ships providing a solution with a clear environmental impact.

Philip Brachet

Graduated from the University of Strathclyde in 2005 with a PhD degree in Engineering. From there, started a career at SINTEF in Oslo as a researcher in polymers and composite before moving to the Oil and Gas industry with specialising first in Subsea insulation and non metallic materials for subsea tie-in and structures to working now on innovative solutions such as subsea storage technology
