Report from the GH2 Maritime Decarbonisation Roundtable, 10 March 2025, London

On 10 March 2025, the Green Hydrogen Organisation (GH2) and the Skies and Seas Hydrogen-fuels Accelerator Coalition (SASHA) hosted the International Maritime Decarbonisation Roundtable in London, alongside a visit aboard the Green Pioneer. With the International Maritime Organization (IMO) set to decide on greenhouse gas (GHG) pricing mechanisms in April, discussions focused on the need for a strong business case for green fuels to avoid reliance on transitional solutions like LNG or biofuels. Dr Andrew Forrest, Executive Chairman of Fortescue, highlighted that green ammonia-powered shipping is already feasible and urged regulators to fast-track the adoption of Real Zero fuel standards.

Key takeaways from the event emphasized that a universal levy is the most effective way to scale green fuel production and reduce costs, while credit trading schemes could create instability and deter long-term investment. Without clear incentives, shipowners may opt for incremental fixes that delay real decarbonisation. The discussion also underscored the risks for Small Island Developing States (SIDS) and Least Developed Countries (LDCs), which need predictable funding to support their transition.
