H2SITE’s AMMONIA to H2POWER technology for ammonia cracking onboard has been approved in principle by Lloyd’s Register (LR). The technology is a containerized solution that uses ammonia to produce fuel-cell-quality hydrogen, which can be used by hydrogen fuel cells for the vessel’s electrical power or consumed directly in an internal combustion engine.
Ammonia cracking is gaining momentum as a potential hydrogen carrier for onboard applications, and this system is based on H2SITE’s hydrogen-selective membranes. These membranes overcome the thermodynamic limitations of the ammonia cracking reaction by recovering hydrogen continuously, resulting in virtually complete ammonia conversion and higher efficiencies at lower temperatures, reducing overall energy consumption and footprint.
H2SITE operationally demonstrated its ammonia to hydrogen power technology last November when the Zumaia Offshore’s Bertha B vessel carried the technology onboard, validating its performance in actual offshore conditions. “We are proud to have achieved this milestone, as it validates the design and safety of our onboard ammonia cracking technology for decarbonizing maritime applications based on membrane reactors,” said Jose Medrano Technical Director at H2SITE.
The AMMONIA to H2POWER systems will be integrated with both propulsion systems and auxiliary power units to serve a range of vessels, from offshore platforms to tankers and gas carriers.
