Our product

Alma provides clean power systems for ocean industries and other remotely located power needs, enabling zero emissions. Alma has developed a highly efficient energy solution based on solid oxide high-temperature fuel cell technology with the ability to run on multiple fuels. In a time where future green fuel availability is uncertain, Alma clean power technology allows ship owners to reduce risk by choosing the engine, not the fuel type.

Alma Clean Power Modules

Our modules are specially designed for very high efficiency capable of operating on a wide variety of fuels. The core building block – the Solid Oxide Fuel Cell stack box – can be multiplied for use in MW-size units. We are currently building containerized power modules that include all balance of plant equipment and safety systems according to maritime requirements, and preparing for world-leading zero emission MW-size demonstrations in commercial vessels.

Technology Highlights


Safe & compliant

Developed to comply with maritime safety rules & regulations for operation in maritime


Fuel flexible

High temperature fuel cells can run on multiple fuels such as ammonia, hydrogen, LOHC, LNG,LPG, methanol, ethanol, etc.


Maritime DNA

Compact design requirement for remote maritime and offshore sectors



Superior efficiency (>60% electrical efficiency + valuable heat)



Solution developed over 30+ years of research, testing and verifications


OPEX reduction

End-user cost savings due to lower fuel consumption, high efficiency and less regular maintenance

Applicable sectors

Flexibility in terms of size, power and fuel type, makes it possible to use our highly efficient clean power modules for most applications.



The shipping sector is responsible for ~3% of CO2 emissions, 13% of SOx emissions and 12% of NOx emissions globally. IMO 2030 targets to reach at least 50% reduction by 2050. Most of the emissions come from deep-sea shipping, which is also the most difficult segment to decarbonize. The Alma technology can eliminate all three emission types, enabling zero emission deep-sea shipping. The picture shows Viking Energy which will be retrofitted with 2 MW Alma fuel cells running on ammonia, allowing it to sail solely on the clean fuel for up to 3,000 hours annually.

Although this sector will be phased out eventually, many decades with high activity remains. This makes the oil & gas sector a market with high priority for Alma to provide decarbonizing technology. Replacing gas turbines with fuel cells has the potential to reduce emissions offshore by up to 90%. Gas turbines exploit roughly one third of the energy in natural gas whereas a fuel cell can double the efficiency, while producing concentrated heat. Fuel cell systems with carbon capture will make offshore installations independent from electricity cables to land. Many platforms already have injection systems available, making CO2 storage relatively easy to implement.

Subsea is the definition of a remote area in the ocean industries. More than 70% of the Earth’s surface is covered by water, subsea installations for a variety of applications has huge potential.

Sustainably harvested proteins is demanded by the consumer markets, pushing fish farmers to rethink their conventional way of harvesting, such as moving the fish farms offshore. Highly efficient and compact clean power system is needed at such remote locations.

LNG operated power plants with fuel cells can contribute to reduce emissions from power generation in the transition phase towards only renewable energy sources. Our high temperature fuel cells can produce electricity and heat from natural gas. The system has very high efficiency levels compared to conventional power plants and the possibility to capture CO2 in a very cost-effective manner. The result is zero emission energy from natural gas and significantly reduced operational costs.

The ShipFC project will demonstrate that long-range zero-emission voyages with high power on larger ships is possible. Viking Energy is the world’s first ammonia operated vessel with a Solid Oxide fuel cell system provided by Alma Clean Power.
