H2SITE Launches Norwegian Subsidiary to Accelerate Ammonia-to-Power and Maritime Decarbonisation

BILBAO, Spain & BERGEN, Norway — H2SITE launched H2SITE Norway ASa new subsidiary based in Bergen, to power the future of marine hydrogen solutions. The company’s presence in Norway reflects its intention to work closely with the marine and offshore industry and to support the effective deployment of hydrogen-based solutions for shipboarding.

which can be supplied directly to fuel cells or integrated into engines. This capability is particularly important in marine and offshore applications, where operational reliability, system integration and fuel efficiency are critical.

in this technology. The country combines a strong maritime heritage with clear climate ambitions and a rational approach, focused on innovative goals and first-of-a-kind projects. Norway is already testing the use of commercial ammonia ships. With a local presence, H2SITE aims to work directly with Norwegian ship owners, shipyards and technical partners to adapt its systems to real ship profiles and operating conditions.

H2SITE believes that the commercial and regulatory risks of delaying decarbonisation now outweigh the risks associated with adopting new technologies. Ammonia, when used as an energy carrier and combined with efficient conversion systems, provides a reliable route to zero-emission vessels and long-term compliance rather than short-term mitigation.

As of 2023, H2SITE built and operated ammonia crackers for more than

including ongoing ongoing operations in appropriate areas. Ocean-focused projects like

have faced integration with fuel cells and engines. In parallel, H2SITE builds

and has reached the production capacity needed to support the first commercial projects.

Vessel types such as RoRo, bulk carriers, platform supply vessels and tankers face technical and operational constraints. While ammonia-to-power 4-stroke engines are approaching commercial readiness, challenges remain at low loads, including ammonia slip and fuel demand. Fracking allows ship owners to benefit from liquid ammonia storage and innovation while producing hydrogen which improves combustion and enables the use of fuel cells for more efficient auxiliary power. Hybrid solutions, along with fuel-cell propulsion, offer practical paths to zero-ammonia ships.

While international frameworks such as IMO regulations continue to evolve, the FuelEU Maritime and EU Emissions Trading System are already shaping investment decisions and will gradually strengthen over time.

The next step is pilot and demonstration projects that allow systems to be integrated and used under real-world conditions.

deploying systems to real work sites, collecting operational data and refining solutions in close cooperation with the Norwegian maritime industry. This strategic move highlights H2SITE’s commitment to addressing one of the key challenges in marine decarbonisation: enabling efficient and economical on-board hydrogen production. By making hydrogen available at sea for both propulsion and auxiliary systems, we are actively supporting the transition to a cleaner and more competitive future in the shipping industry.
