SOFC-based power supply from ammonia, hydrogen, methanol

Providing reliable, environmentally friendly power in remote regions is a significant challenge. Traditional diesel generators are not only less environmentally friendly but also operate with limited efficiency. To address this issue, we are working on a more efficient and sustainable alternative that can utilize various energy carriers. In cooperation with Hydro-Québec​, a Canadian electric utility, and its research institute (Institut de recherche d‘Hydro-Québec – IREQ) we delivered and operated a test bench in Varennes to develop greener power generation systems for northern communities that are not connected to the main grid.

The SOFC stack developed at Fraunhofer IKTS offers many degrees of freedom for efficient operation thanks to its high operating temperatures, which offers simple fuel treatment. Robust stack technology supports the use of various fuels and demonstrates tolerance to partial internal cracking when using ammonia, thus contributing to a durable and reliable system design. Our SOFC laboratory test bench can be powered by ammonia, methanol, or hydrogen. Particular attention was paid to the fuel treatment (cracking/reforming), systems integration and thermal management. All topics related to system development, safety, controls implementation, adaptation to applicable standards and lab integration were addressed in this project.

The compact SOFC-based system generates power and heat in a single unit – without CO₂ emissions when using ammonia or hydrogen, and without other harmful byproducts. Initial tests show that its efficiency and eco-friendliness can surpass traditional systems, potentially influencing the future of energy supply in a sustainable way.
