Successful Test of World’s First 6 kW Direct Ammonia Fuel Cell System

Norway-based Alma Clean Power has successfully tested the world’s first 6 kW direct ammonia fuel cell system. The company is developing modularized Solid Oxide Fuel Cell (SOFC) systems for use in the ocean. The 6-kW unit is the first step towards a complete 100-kW SOFC module, and achieved an electrical efficiency of 61-67%. This achievement marks the highest power output ever demonstrated with direct ammonia solid oxide fuel cells.

Alma’s technology allows for direct feeding of ammonia into the fuel cell system, eliminating the need for energy-intensive pre-treatment to convert the fuel into hydrogen. Green ammonia, produced through renewable-powered electrolysis, is a carbon-free fuel with tremendous potential for decarbonizing the maritime industries.

The system is operating stably and generating consistent electricity, with testing set to continue throughout the summer to further optimize the setup. The next step is the assembly and testing of a complete 100-kW module, which will serve as the foundation for larger ship installations. Rune Tveit, Project Manager, describes the system’s operation as rewarding, noting that it operates seamlessly 24/7 and is remotely monitored with a sophisticated safety and control system. The SOFC modules are combustion-free and have no rotating parts, designed to operate autonomously with little to no maintenance required for extended periods.

Alma Clean Power’s successful test of the 6 kW direct ammonia fuel cell system represents a major milestone in developing cleaner and more efficient energy solutions for the maritime industry. The company’s innovative technology not only eliminates the need for energy-intensive pre-treatment processes, but also contributes to the decarbonization efforts in the sector. As the testing continues and the 100-kW module is assembled and tested, the potential for larger ship installations becomes more tangible. This achievement highlights the progress being made in transitioning towards sustainable energy sources and showcases the capabilities of direct ammonia fuel cells in delivering high power output and efficiency.
