Finnish naval architecture and engineering company Deltamarin has joined H4PERION, a Horizon Europe project funded by the European Union and coordinated by the University of Vaasa, with the objective of accelerating hydrogen-based solutions for zero-carbon long-distance shipping.
The four-year initiative brings together 16 partners from seven European countries representing multiple areas of the maritime industry, including ship design, engine manufacturing, vessel operations, classification societies and research organisations.
The programme aims to develop and demonstrate practical technologies capable of reducing greenhouse gas emissions while maintaining the operational reliability required for long-distance maritime transport.
At the centre of the H4PERION project is the development and validation of a full-scale hydrogen-capable internal combustion engine. The programme will also focus on fuel-flexible engine concepts, hydrogen supply systems and advanced emissions control technologies designed to support future low-carbon vessel operations.
Several technologies developed through the project will be tested both onboard Wasaline’s ferry Aurora Botnia and in full-scale laboratory environments. The results are expected to contribute to future vessel and system development across the maritime sector.
Beyond propulsion technology itself, the project also addresses broader industry requirements linked to hydrogen adoption, including safety procedures, regulatory frameworks and training programmes for seafarers and port personnel. The objective is to help establish the operational and institutional foundations needed for the wider introduction of alternative fuels at sea.
Within the programme, Deltamarin will focus on two main areas. The company will contribute to the integration and design of onboard installations while also supporting validation of the project’s key performance indicators. In addition, the firm will evaluate how the technologies developed through H4PERION could be transferred across multiple vessel categories to improve scalability and commercial adoption.
According to the company, the goal is to ensure that the project delivers solutions suitable for broader commercial shipping applications rather than remaining isolated demonstration concepts.
The initiative targets one of the shipping industry’s most pressing decarbonisation challenges: finding fuels capable of supporting long-distance operations while delivering high energy density and dependable operational performance.
Hydrogen is increasingly viewed as one of the leading candidates for achieving those goals, although large-scale practical deployment still faces significant technical and operational hurdles.
By prioritising full-scale demonstrations and collaboration across the maritime value chain, H4PERION aims to move hydrogen technologies closer to commercial reality and support the shipping industry’s long-term climate ambitions.
