H2SITE’s AMMONIA to H2POWER Technology Receives Approval in Principle From Lloyd’s Register

Ammonia cracking is gaining momentum as a potential hydrogen carrier for onboard applications and this system is based on H2SITE’s hydrogen-selective membranes that overcome the thermodynamic limitations of the ammonia cracking reaction by recovering hydrogen continuously and resulting in virtually complete ammonia conversion and higher efficiencies at lower temperatures, reducing overall energy consumption and footprint.

In awarding the AIP, the design and arrangement evaluation included an overall examination of fundamental aspects of the design and compliance with LR’s Rules and Regulations for the Classification of Ships using Gases or other Low-flashpoint Fuels. A preliminary appraisal of rules was undertaken, followed by a risk assessment conducted to ensure that the risks arising from the use of ammonia and hydrogen are addressed according to LR’s ShipRight Procedure for Risk-Based Certification (RBC).

H2SITE operationally demonstrated its ammonia to hydrogen power technology last November when the Zumaia Offshore’s Bertha B vessel carried onboard AMMONIA to H2POWER technology, 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. Having commissioned our first cracker and fuel cell unit last year aboard the supply vessel Bertha B, we are currently scaling up the technology and designing MW-scale units." according to Jose Medrano Technical Director at H2SITE.

These 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.

Mark Darley, Chief Operations Officer, Lloyd’s Register added: “H2SITE's AMMONIA to H2POWER technology represents an exciting opportunity for shipowners to convert ammonia, and other feedstocks such as methanol, to hydrogen onboard their vessels without using additional gas separation technology”.

“We are pleased to award the AiP for this novel solution, and we remain dedicated to working with the maritime value chain to provide zero-emission power solutions that can contribute towards a greener, more sustainable future.”

About H2SITE

H2SITE was created in 2020 and has an exclusive technology of reactors and separators for the conversion of different feedstocks into hydrogen, among which are ammonia, methanol, or synthetic gas, in addition to the separation of hydrogen from gaseous mixtures in low concentration for applications in salt caverns or geologic hydrogen.
