The GreenVoyage2050 Programme from the International Maritime Organization (IMO) and the International PtX Hub joined forces to train the next generation of maritime decarbonisation experts. The Train-of-Trainers programme, held in London in July 2025, equipped participants with the skills to deliver trainings on renewable PtX fuels for shipping in countries around the world.
Over the course of five days, more than 20 participants from across the globe gathered at the IMO’s headquarters in London to engage in interactive sessions covering the climate impact of international shipping, emerging fuel technologies, the strategic role of ports in the energy transition, and national fleet decarbonisation pathways. A strong emphasis was placed on practical training: participants learned how to deliver selected modules themselves, received peer feedback, and explored how to adapt training content to their national contexts.
This training is part of a deepening collaboration between the IMO and the International PtX Hub, aimed at supporting developing countries in preparing for a cleaner and more sustainable maritime future.
This programme is a critical enabler for cascading renewable PtX knowledge to national actors in the maritime sector. The shared learning and interactive methodology will empower our trainers to deliver impactful workshops that support the green shipping transition worldwide. We are building a community of trainers who can help share this knowledge across the world.

The training modules, co-created with the IMO, now offer a solid tool for scaling capacity development at the nexus of energy and shipping – a key area for climate action. By training experts from different countries, we are helping to turn global ambition into local action. These new trainers will now support their own countries to prepare for the future of shipping.

One participant summarised the programme as follows: “The most interesting aspect was to learn about the IMO Net-Zero Framework and how IMO might itself be a first mover as an UN organisation with this very innovative approach, including compliance targets and the revenues out of the Net-Zero Fund.” Another participant emphasised how the acquired skills will be useful in the future: “For me the most valuable takeaway would be the increase in confidence and development of training skills to deliver engaging and impactful trainings.”
All participants had previously completed a foundational course on Power-to-X, the PtX.Basic Training. After this advanced training in London, they are now ready to deliver tailored national workshops, contributing to broader efforts under the IMO’s GreenVoyage2050 Programme and the International PtX Hub’s mission to promote sustainable PtX solutions worldwide.
GreenVoyage2050 Programme
GreenVoyage2050 is a major technical cooperation programme initiated by the IMO to assist developing countries in reducing GHG emissions from shipping, aligning with the 2023 IMO GHG Strategy. Phase I of GreenVoyage2050 (2020-2023) supported partnering countries in developing policy frameworks and pilot projects to reduce GHG emissions from ships. Phase II (2024-2030) continues and expands this support, leveraging funding from the Governments of Denmark, Finland, France, Germany, the Netherlands, and Norway.
