Ammonia cracking is gaining momentum as a potential hydrogen carrier for onboard applications and this system is based on H2SITE’s hydrogen selective membranes which overcome the thermodynamic limitations of the ammonia cracking reaction. ammonia by continuously recovering hydrogen and resulting in virtually complete conversion of ammonia and higher yields at lower temperatures, thereby reducing overall energy consumption and carbon footprint.
As part of the grant of Approval in Principle, the assessment of the design and arrangement included an overall review of fundamental aspects of the design and compliance with LR rules and regulations for ship classification using gases or other low flash point fuels. A preliminary assessment of the rules was undertaken, followed by a risk assessment to ensure that the risks arising from the use of ammonia and hydrogen are taken into account in accordance with the ShipRight procedure for risk-based certification by LR.
H2SITE operationally demonstrated its ammonia-to-hydrogen conversion technology last November when Zumaia Offshore’s Bertha B vessel embarked on AMMONIA to H2POWER technology, validating its performance in real offshore conditions.
We are proud to have reached this important milestone, as it validates the design and safety of our onboard ammonia cracking technology for the decarbonization of membrane reactor-based maritime applications. After commissioning our first cracking and fuel cell unit last year aboard the supply vessel Bertha B, we are now developing the technology and designing MW scale units declares Jose Medrano, Technical Director, H2SITE.
These AMMONIA to H2POWER systems will be integrated into both propulsion systems and auxiliary power units to serve a wide range of boats, offshore platforms, oil tankers and gas tankers.
Mark Darley, Head of Operations, Lloyd’s Registeradds: H2SITE’s AMMONIA to H2POWER technology represents a promising opportunity for shipowners to convert ammonia, and other feedstocks such as methanol, into hydrogen on board their vessels without the use of additional gas separation technology.
We are pleased to grant this approval in principle to this new solution, and we remain committed to working with the maritime value chain to deliver zero-emission energy solutions that can contribute to a greener and more sustainable future.
About H2SITE
H2SITE was created in 2020 and has exclusive reactor and separator technology for the conversion of different raw materials into hydrogen, including ammonia, methanol or synthetic gas, in addition to hydrogen separation from low concentration gas mixtures for applications in saline cavities or geological hydrogen.
