Wärtsilä joins EU-funded consortium to further accelerate zero-carbon shipping for long-distance vessels in International Shipping News , Shipping: Emission Possible 07/05/2026 Technology group Wärtsilä has joined H4PERION, an EU-funded Horizon Europe project led by the University of Vaasa in Finland, to help accelerate the transition to zero-carbon long-distance shipping. The four-year project will develop and demonstrate solutions to improve engine efficiency and significantly reduce greenhouse gas emissions. Wärtsilä will contribute by developing a combustion concept that enables internal combustion engines to operate safely and efficiently on a blend of hydrogen and biomethane, with the aim of achieving up to 100% hydrogen operation in open-sea conditions. “Several low‑carbon fuels are being explored within the industry, and hydrogen is considered one potential zero‑carbon option. By focusing on its practical application and safety in maritime contexts, the H4PERION project aims to advance innovation and set new standards for the industry. Collaboration across Europe will be key in achieving these outcomes,” says University of Vaasa’s Research and Development Director, Henri Karimäki. In addition, Wärtsilä will develop a catalyst system to reduce methane slip and other emissions, supporting a lower overall lifecycle carbon footprint. Wärtsilä will demonstrate selected technologies onboard Wasaline’s ferry ‘Aurora Botnia’, with a focus on reducing the vessel’s emissions – particularly methane slip. The project also includes training programmes for crew and port workers and activities to support the safe use of sustainable fuels.
