H2SITE validates on-board ammonia cracking system generating high-purity hydrogen coupled with PEM fuel cell

H2SITE has validated the first ammonia cracker to produce high-purity hydrogen for onboard power generation using a PEM fuel cell. An integrated membrane reactor has been installed and operated on board of the BERTHA B supply ship, sailing the shores of the Gulf of Biscay.

Maritime transport is responsible for 2% of global greenhouse gas emissions, presenting significant potential for emission reduction by transitioning from hydrocarbons to green fuel options, such as hydrogen.

Ammonia is gaining traction as a potential hydrogen carrier for onboard applications. It can be used directly in engines, or it can be cracked into hydrogen and used in fuel cells. Before hydrogen is used, purification is necessary, especially if traces of ammonia are present.

H2SITE’s membrane reactors ensure all the ammonia is transformed, while delivering a high-purity hydrogen to the fuel cell in a single process step. During navigation, as part of the H2OCEAN project, H2SITE’s cracker has successfully powered the ship’s auxiliary services. This accomplishment was made possible due to the collaboration with players active in the maritime decarbonization segment such as Zumaia Offshore, Erhardt Offshore, Ajusa, and TECNALIA, along with the participation of Enagas and ABS.

H2SITE was established in 2020 and possesses technology for reactors and separators, facilitating the conversion of various feedstocks into hydrogen. These include ammonia, methanol, or synthetic gas, as well as the separation of hydrogen from gaseous mixtures in low concentrations for applications in salt caverns or geological hydrogen.



I like HTPEM in the application as they are far less fussy about trace impurities.
SOFC would also do the job, but are also an immature technology,
