H2SITE has successfully implemented the first system to produce hydrogen from ammonia on board a ship, using membrane reactor technology to generate electricity for the ship’s auxiliary consumption.
This advancement represents a significant milestone for the company, allowing it to further scale its integrated membrane reactor technology as a solution to address the challenge of decarbonization in shipping . The operation took place on November 18 on the supply ship “Bertha B”, which set sail from the Port of Bermeo and sailed along the coasts of the Bay of Bizkaia.
About the H2SITE system
During navigation, the installed system transforms ammonia into high-purity hydrogen , which then powers the fuel cell to produce electricity for the vessel’s auxiliary services. The initiative, known as H2OCEAN , had the collaboration of prominent international actors in the field of maritime decarbonization, including its partner TECNALIA, as well as Zumaia Offshore, Erhardt Offshore, Ajusa, Enagas and ABS.
José Medrano, technical director of the company explains: “Our membrane reactor technology not only improves system efficiency, but also makes the unit more compact. “This is especially important in applications where space is limited, such as on board a ship.” And he adds that “we have focused our design efforts on minimizing ammonia consumption, which will be key for the expansion to higher power units.””.
Shipping contributes 2% of global greenhouse gas emissions, offering significant potential for emissions reductions by switching from hydrocarbons to green fuel options, such as hydrogen.
Ammonia stands out as one of the candidates for the production of hydrogen in onboard applications, because its supply chain is widely known (being the most transported liquid worldwide) and it can be used both directly in engines and transformed into hydrogen for use in fuel cells.
