Subhydro AS is working on the development and commercialisation of disruptive technology for large-scale electricity storage. Our patent-pending innovation involves proprietary technology for the construction of a subsea pumped hydroelectric plant. We combine state-of-the-art technology from the hydro power and offshore oil and gas industry to open up new possibilities for pumped hydro storage at offshore locations.
Government funded industry innovation project
Subhydro AS has teamed with world leading industry partners and research organisations to perform a research project and was recently granted project funding from the Research Council of Norway. Our team includes global engineering consultant COWI, offshore EPC specialist KVAERNER and hydro power specialist DynaVec. The project team is complemented with scientific experts from three institutes of SINTEF, the largest independent research organisation in Scandinavia: SINTEF Energy Research, SINTEF MARINTEK and SINTEF Building and Infrastructure.
Subhydro AS is based in Oslo, Norway, and is privately owned. Interested industry partners and investors can contact us under info.@.subhydro..com.
Over 99% of world-wide electricity energy storage is provided by mature pumped hydro technology. Subhydro AS aims to expand the application of this existing technology into deep water offshore locations. Subsea pumped hydro storage avoids many planning and permitting problems, which often delay new onshore hydro power projects. The global potential for new subsea pumped hydro storage is significant.
Low cost grid storage for transmission system operators and utilities
Depending on available water depth our technology offers gigawatt hours of storage on a 100 - 1000 MW scale at over 80% roundtrip efficiency. Customers can expect all benefits of a modern variable speed pumped hydro plant, including primary control power. Capital cost are expected to be comparable to existing onshore hydro power projects.
Offshore wind and electrification of oil and gas platforms
Combined with renewable energy sources such as deep sea offshore wind, subsea pumped hydro storage enables the autonomous electrification of offshore oil and gas platforms. This application has potential to significantly reduce CO2 emissions in the offshore oil and gas industry, which typically relies on gas turbine generators as electricity supply.
