Navantia Seanergies couples with H2SITE to develop commercial systems to produce high purity hydrogen on board.

Navantia Seanergies, the green energy division of Navantia, and H2SITE, a pioneer in hydrogen production technology, have signed a strategic agreement to promote the development of on-board hydrogen-based power generation systems for commercial marine applications.

Navantia, which has already developed hydrogen-based power generation technology for the S80 class submarines, is looking to launch new marketable solutions based on green hydrogen-derived fuels - ammonia and methanol - which are set to be the solution for the decarbonisation of ships with high performance and autonomy demands.

H2SITE has a technology that transforms ammonia and methanol into high purity hydrogen (which meets fuel cell requirements). This domestic technology achieves high conversion efficiency due to its one-step reaction and separation, which is a substantial improvement over other conversion technologies. These systems have already been tested on land and maritime applications on a pilot scale, and are now being scaled up for larger applications thanks to strategic collaborations such as the one just signed.

This collaboration between H2SITE and Navantia Seanergies will enable the development of on-board membrane reactor systems capable of storing ammonia and methanol and of producing hydrogen on board from these elements, using processes known as "cracking" in the case of ammonia and "reforming" in the case of methanol. Both processes split these molecules to produce high-purity hydrogen, optimal for powering a fuel cell. This on-board technology will contribute to cleaner propulsion for the maritime sector and the decarbonisation process.
