Rotterdam, Netherlands – Fortescue has partnered with the Green Hydrogen Organisation (GH2) and digital platform provider Trovio to complete the first-ever issuance of a digital fuel certificate for an ammonia-to-ship bunkering operation. The pilot marks a major step in advancing transparent and traceable green fuel supply systems for the maritime sector.
The transaction, carried out during a recent ammonia fuel transfer at the Port of Rotterdam to Fortescue’s Green Pioneer—the world’s first ocean-going, dual-fuel ammonia-powered vessel—was recorded on Trovio’s CorTenX registry platform. The platform captured verified data points, including fuel origin, handling, and environmental attributes, in an immutable digital format.
Milestone in Maritime Fuel Certification
The pilot is seen as a foundational development for future green fuel infrastructure, particularly in the maritime industry, which is under increasing pressure to decarbonise.
Andrew Hoare, Fortescue’s Head of Green Shipping, emphasised the importance of the pilot:
“This initiative demonstrates how digital systems can underpin trusted, auditable certification of next-generation marine fuels. Beyond just physical fuel delivery, platforms like CorTenX can ensure transparency, regulatory compliance, and robust emissions tracking.”
Trovio CEO Jon Deane added that CorTenX aims to be the backbone for digital certification of green fuels:
“We are proving that digitising the fuel lifecycle not only boosts trust and integrity but also streamlines compliance and supports faster adoption of low-emission fuels.”
Supporting Regulatory Goals and Market Readiness
The initiative aligns with the International Maritime Organization’s recent agreements to introduce mandatory emissions limits and greenhouse gas pricing. According to GH2 CEO Jonas Moberg, the need for credible systems that verify not only the volume but the sustainability attributes of green fuels—such as renewable e-ammonia—is urgent.
“The pilot shows we’re ready to track and certify these fuels as soon as they’re commercially deployed,” Moberg said.
CorTenX: A Digital Backbone for Clean Fuel Markets
The CorTenX platform was developed to meet the needs of environmental markets through a secure, API-driven registry capable of tracking detailed supply chain and emissions data. In this pilot, it captured vessel and port details, time-stamped the transaction, and recorded sustainability metrics that comply with global regulatory frameworks, including the Green Hydrogen Standard and IMO protocols.
Crucially, the platform also enables mass balance chain-of-custody methodologies, allowing for robust emissions accounting and facilitating claims for Scope 1 and Scope 3 emissions reductions across complex supply chains.
Laying the Groundwork for Scalable Green Fuel Deployment
While much of the conversation around green ammonia as a marine fuel has focused on technical feasibility and safety, this pilot highlights the equally important role of digital certification systems in scaling adoption. It offers a model for how traceability and verification infrastructure can be built into global bunkering operations, supporting both environmental goals and commercial transparency.
As the maritime sector faces mounting regulatory requirements and growing demand for low-carbon solutions, Fortescue, GH2, and Trovio are setting a precedent for how digital tools can bridge the gap between sustainability ambition and market implementation.
