Clean Highly Efficient Offshore Power (CHEOP)

Prototech is building a robust 10kW solid oxide fuel cell (SOFC) stack ideal for offshore use, while simultaneously designing a MW-scale system for future applications where the SOFC stack will be one of the basic building blocks.

Clean Highly Efficient Offshore Power (CHEOP)

For the offshore industry to reduce emissions, increase power efficiency and limit the need for long power cables to remote offshore locations, a fuel cell system developed for offshore power is an ideal candidate. With electric efficiencies of 60%, the fuel consumption and CO2 emissions can be reduced to 50% of the original values. The long-term vision is zero emission power production by including carbon capture and storage (CCS).

For topside utilization (see concept image), the goal is replacing the existing gas turbines with fuel cells. Due to the importance of footprint and mass on offshore facilities, a key element is to keep the fuel cell modules compact without the need for extended structures.


A result of a pre-project proved that the fuel cells also can be placed subsea and produce the power necessary for an increasing number of subsea factories, in situ. Local natural gas resources will be utilized as fuel, and air will be drawn from the surface through a long snorkel. The Subsea Fuel Cell will hence remove the need for additional power in subsea factories, both from land cables and from floating platforms.

The project is funded by the Research Council of Norway (RCN), through the PETROMAKS2 program. Industrial partners are Statoil Petroleum AS and AS Norske Shell.
