H2SITE joins Ocean Hyway Cluster

Jan 23

We are excited to welcome H2SITE as our newest member and have them onboard a community that spans the full maritime and energy ecosystem.

Their membership strengthens our growing international network - especially between Norway and Spain within the maritime energy transition, and we are eager to explore new collaborative opportunities.

Bringing breakthrough ammonia-to-hydrogen technology to the maritime sector

As H2SITE joins OHC, the company steps further into a rapidly evolving maritime landscape where hydrogen and ammonia are emerging as essential fuels for the future. With several business lines under its umbrella, H2SITE is currently placing particular emphasis on the maritime sector - and especially on the development of onboard and port-side ammonia cracking technology. This technology enables ships and ports to produce high-purity hydrogen directly from ammonia, opening the door to zero-emission propulsion and auxiliary power systems.

H2SITE is advancing both onboard and onshore applications, with early deployments and pilot projects already underway. These initiatives are designed to accelerate commercial-scale adoption and demonstrate how maritime hydrogen solutions can become a practical reality rather than a distant ambition.

Here you can see the Approved in Principle (Lloyd’s Register), the world’s first on-board ammonia cracking system, producing high-purity hydrogen to power a PEM fuel cell.

A market full of opportunity - and a few challenges

The company sees enourmous potential in the maritime industry’s accelerating push toward decarbonization. Ammonia is gaining traction as a hydrogen carrier thanks to its high energy density and well-established global transport infrastructure.

Tomas Crespo, Maritime Business Development Manager at H2SITE explains that Norway represents a particular promising environment: a mature maritime ecosystem, strong political commitment to green innovation, and access to real-world pilot fleets create ideal conditions for early adoption.

But opportunity comes with challenges. The biggest hurdle is ensuring that ammonia-to-hydrogen conversion remains both efficient and cost-competitive. H2SITE is tackling this head-on with its patented integrated membrane reactor technology, capable of producing 99.97 % pure hydrogen in a single step at 425 °C. This approach delivers an average of 22 % cost reduction compared to conventional systems - a significant advantage in a market where cost and efficiency determine scalability.

Sustainability at the core

For H2SITE, sustainability isn’t a side project - it’s at the core of the company’s mission.

Their technology directly supports zero-emission maritime operatations, enabling clean hydrogen use without relying on fossil fuels. The company’s sustainability priorities include:

Reducing greenhouse-gas emissions from shipping
Improving energy efficiency through single-step conversion processes
Supporting the transition toward hydrogen and ammonia as long-term maritime fuels
Aligning innovation with globale climate goals

By focusing on these areas, H2SITE aims to contribute meaningfully to a cleaner, more resilient maritime sector.

A new pilot project on the horizon

Looking ahead, H2SITE is preparing an exciting new pilot project in Norway. The initiative will demonstrate continuous onboard hydrogen production for PSV vessels operating along the Western Coast. The project aims to validate a 2 MW ammonia-to-hydrogen system under real maritime conditions, developed in collaboration with Norwegian shipowners and technology partners.

Successful execution of this pilot will mark a major milestone - not only for H2SITE, but for the maritime hydrogen sector as a whole. It has the potential to position Norway as one of the first markets to adopt large-scale onboard ammonia cracking systems.

Why Ocean Hyway Cluster?

Joining OHC was a strategic decision.

«As Norway’s leading network for the hydrogen and ammonia value chain, the cluster brings together shipowners, technology developers, designers, and public stakeholders - all of whom align closely with H2SITE’s target markets. Membership offers access to collaboration opportunities, knowledge sharing, and accelerated pilot deployment. These elements are essential for scaling hydrogen solutions and ensuring that new technologies reach vessels, real ports, and real operations» says Tomas Crespo.
