Shipping must join hydrogen push

Launched at London International Shipping Week on 16 September, the company’s first maritime decarbonisation report, Deadlock: What’s Stopping Shipping’s Carbon-Neutral Fuel Transition?, argues that shipping alone cannot achieve net zero emissions by 2050 without pooling demand for green hydrogen with industries such as steel, power generation and fertiliser.

“Reaching net zero is not only about fuels or systems, but about forging a new paradigm of partnership,” said Accelleron chief executive Daniel Bischofberger in the report’s foreword. “Shipping has always overcome challenges through solidarity and pragmatism. Now we must do the same on a global scale.”

Accelleron’s analysis finds that efficiency measures, including vessel retrofits and digital solutions, could cut shipping emissions by over 30% by 2030, surpassing IMO targets. However, true decarbonisation will require an estimated 100–150 million tonnes of green hydrogen annually by 2050, far more than the 38 million tonnes currently in the pipeline.

The report emphasises the need to aggregate demand to drive investment in hydrogen infrastructure. “Rather than competing for fuels, we must build critical mass together,” said Bischofberger.

Shipping, aviation, steel, cement and agriculture collectively need 500 million tonnes of green hydrogen and US$9 trillion in investment, according to the study.

The report was presented alongside a stakeholder dialogue featuring leaders from the shipping and energy sectors, with Accelleron aiming to position the maritime industry as a driver in the global energy transition.
