Deltamarin contributes to advancing hydrogen-powered shipping in new EU-funded H4PERION project in Shipbuilding News 14/05/2026 Deltamarin joins H4PERION, a new EU-funded Horizon Europe project coordinated by the University of Vaasa, aiming to accelerate the transition towards zero-carbon long-distance shipping through hydrogen-based technologies. The four-year project brings together 16 partners from seven European countries across the maritime value chain – from ship design and engine development to vessel operation, classification, and research. The objective is to develop and demonstrate practical solutions that significantly reduce greenhouse gas emissions while maintaining the high reliability required for long-distance maritime transport. Taking hydrogen from concept to real-world maritime application Decarbonising long-distance shipping remains a major challenge, requiring solutions that combine high energy capacity with operational reliability. Hydrogen is increasingly seen as a promising zero-carbon fuel, but its practical application at sea still needs to be proven. H4PERION addresses this by developing and demonstrating a hydrogen-capable internal combustion engine at full scale. The project brings together key elements such as fuel-flexible engine concepts, hydrogen supply systems and advanced emissions control. These technologies will be tested both onboard Wasaline’s ferry Aurora Botnia and in parallel full-scale laboratory conditions, with the results feeding into future vessel and system development. Collaboration driving maritime decarbonisation Beyond technological development, H4PERION also addresses the broader ecosystem required for hydrogen adoption in shipping. The project includes activities related to safety, regulatory development, and training for crew and port personnel, supporting the safe and efficient implementation of new fuels in maritime operations. By combining expertise from across Europe, the project aims to establish new indust
