MAIRE announces that NEXTCHEM and Siemens Energy have signed a Memorandum of Understanding to jointly develop and commercialize a modular high-temperature methanol fuel cell for maritime applications. The solution targets high-end yachts initially, with plans to expand into industrial, stationary, and off-grid energy markets, enabling efficient, net-zero onboard power generation.
NEXTCHEM will design and supply the advanced methanol fuel cell modules, while Siemens Energy will provide onboard system integration, electrification, and energy management. The fuel cell reforms low-carbon methanol into hydrogen, powering vessels while eliminating emissions of nitrous and sulphur oxides and reducing reliance on fossil marine diesel.
Operational Details:
The first industrial-scale installation is planned for a flagship net-zero yacht currently under construction. The modular fuel cell design allows scalability, adaptability, and application across diverse markets, including data centers, industrial processes, and remote power generation, ensuring a flexible path to net-zero energy solutions.

Strategic Significance:
Fabio Fritelli, Managing Director of NEXTCHEM, emphasized the modular solution covers the entire low-carbon methanol value chain, promoting wider adoption and accelerating demand for sustainable fuels. Giuseppe Sachero of Siemens Energy highlighted the collaboration’s potential to leverage expertise across the energy transition ecosystem, integrating fuel cells into clean fuel technology solutions globally.
