Our product

We provide clean power systems for ocean industries, enabling zero emissions. We have developed a highly efficient power solution based on solid oxide high-temperature fuel cells that can run on multiple fuels.

In a time where future fuel availability is uncertain, our technology allows ship owners to reduce risk by choosing the engine, not the fuel type. Check out our current projects.

Alma Clean Power Modules

Our modules are designed for very high efficiency and can operate 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. Power and heat are generated silently and with no vibrations in a combustion-free process that ensures low or zero emissions. The containerized power modules include all balance of plant equipment and safety systems according to maritime requirements. Our solution is developed over 30+ years of research, testing and verifications.

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 globally, and IMO aims to reach net-zero GHG emissions from international shipping by 2050. Most of the maritime emissions come from deep-sea shipping, which is also the most difficult segment to decarbonize. The fuel-flexible Alma technology enables 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 emission-free for up to 3,000 hours annually.

Despite its eventual phase-out, the oil & gas sector will remain highly active for decades, making it a priority market for Alma to offer decarbonizing solutions. Replacing gas turbines with fuel cells can potentially cut offshore emissions by up to 90%. Fuel cells can double the efficiency of natural gas usage compared to gas turbines and, when combined with carbon capture, render offshore installations self-sufficient in electricity. Many platforms already have injection systems available, making CO2 storage relatively easy to implement.

Encompassing more than 70% of the Earth's surface, our oceans offer immense potential for a variety of subsea installations. In these remote aquatic environments, the need for efficient and reliable energy sources is paramount. Solid Oxide Fuel Cells (SOFC) stand out as a game-changing solution, delivering consistent and sustainable power to unlock the vast opportunities beneath the waves.

As consumer markets increasingly demand sustainably harvested proteins, fish farmers are prompted to innovate and consider alternatives like moving their farms offshore. In these remote settings, there's a need for a highly efficient, compact, and clean power system. By integrating SOFC technology, offshore fish farms can ensure sustainable and reliable operations, aligning with consumer expectations and driving forward eco-conscious practices.

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 cost-effective manner. The result is zero emission energy from natural gas and significantly reduced operational costs.


First of its kind test facility

Alma is proud to be one of the four core partners and investors involved in the Energy House, a state-of-the-art test facility dedicated to advancing the use of new and sustainable fuels. Located at Stord, Norway, this ground-breaking center is the world's first full-scale test facility of its kind. With a fuel infrastructure capable of handling an array of potential future fuels such as H2, NH3, LOHC, methanol, ethanol, and LNG, it will be possible to test up to 3 MW on a variety of powertrains. The Energy House will be Alma’s fast-track path towards commercial fuel cells for the ocean space.
