H2sea Re-Selected for EU Business Hub Japan Mission

H2sea re-selected for EU business mission Japan

H2sea has again been selected to join the EU Business Hub mission to Japan, marking the second time the company will participate in this EU-funded initiative supporting collaboration between European innovators and Japanese industry.

The upcoming mission will take place from 15–19 March 2026 during Smart Energy Week Spring 2026 at International Exhibition Center Tokyo Big Sight in Tokyo. As part of the programme, H2sea will exhibit at the EU Pavilion alongside other European companies and participate in B2B matchmaking, networking events, sector briefings and knowledge exchange sessions. In total, 50 companies from 19 EU countries will join the delegation.

The mission takes place within the broader framework of EU–Japan cooperation in the energy sector centered around the Green Alliance, the Energy Dialogue and the Memorandum of Cooperation on Hydrogen. This continued collaboration provides H2sea with opportunities to further strengthen relationships in Japan’s growing energy transition market and explore future partnerships in offshore hydrogen.

H2sea presents H2PD project at Carbon Trust Knowledge Sprint

H2sea presents at Knowledge Sprint hosted by the Carbon Trust's Integrator programme

During the “Knowledge Sprint” hosted by the Carbon Trust’s Integrator programme last month, H2sea presented the final results of the H2PD (Offshore Hydrogen Production Platform Design) project.

The event was attended by participants from EnBW Energie Baden-Württemberg AG, Shell, SSE Renewables, ScottishPower Renewables, TotalEnergies, and Vattenfall, all part of the Integrator programme – a collaborative industry initiative focused on maximising offshore wind’s contribution to a low-cost, flexible, and predictable energy system.

The H2PD concept is being developed for potential deployment in UK and German waters. The study encompassed four phases: a market screening phase, a technical design phase, a regulatory phase, and an advisory phase.

In addition to the technical designs for a 500 MW offshore hydrogen production platform, H2sea’s presentation focused on cost efficiency, safe operation, transport and installation strategies, including the selection of suitable vessels. The concept combines H2sea’s offshore engineering expertise with practical solutions for enabling scalable, safe, and commercially viable offshore hydrogen production as part of Europe’s future energy mix.

A team of five offshore hydrogen engineers from H2sea participated in the event. Alongside H2sea, Gasunie and TenneT also presented at the Knowledge Sprint, which was organised for the second time by the Carbon Trust.

The Knowledge Sprint provides a valuable platform for sharing technical insights, aligning cross-sector ambitions, and strengthening collaboration on the integration of offshore wind and hydrogen infrastructure.

H2sea Presents at DMEC Deep Dive on Offshore Green Hydrogen

H2sea gives presentation at DMEC during Deep Dive on Offshore Green Hydrogen

H2sea was invited to present at the DMEC Deep Dive, a quarterly international forum hosted by the Dutch Marine Energy Centre (DMEC). DMEC serves as an accelerator and knowledge hub for offshore renewable energy innovation.

The June edition, held on 17 June, focused on offshore green hydrogen, bringing together key stakeholders to explore the latest developments, technological maturity, and market readiness of this rapidly evolving sector. Discussions also addressed the challenges and opportunities of integrating green hydrogen into existing offshore energy infrastructure.

Mohool Misra, project engineer hydrogen at H2sea, shared insights from H2sea’s current research projects and future vision for offshore hydrogen production. Other speakers included Bureau Veritas, the OASIS project, Eindhoven University of Technology, and DMEC itself.

We thank DMEC for the opportunity and look forward to continued collaboration in advancing offshore hydrogen solutions.

H2SEA shares expertise in panel during World Hydrogen Summit

At a panel session during the World Hydrogen Summit, Edwin van Drunen, Managing Director of H2SEA, offered insights on the economic viability of offshore hydrogen initiatives. 

As a distinguished panelist at the HEROW side event, Edwin shared H2SEA’s research insights on the scalability of offshore hydrogen projects.

Joining H2SEA on the panel were representatives from prominent organizations such as Shell, RWE, Eneco, and TNO, the latter also serving as the co-organizer of the HEROW event. HEROW, an acronym for Hydrogen Empowering Revolutionary Offshore Wind, convened industry leaders to explore advancements in offshore hydrogen technologies.

H2SEA carries out assessment on monopile based structures for hydrogen WTG

In co-operation with Delft University of Technology, H2SEA has carried out a structural assessment of monopile-based support structures for offshore hydrogen WTG’s (Wind Turbine Generators).

One of the main questions during the assessment was if decentral hydrogen production on a monopile-based support structure of an offshore wind turbine would be structurally feasible.

The goal of the research was to define the differences in support structure geometry and assess the changes in the design methodology of an offshore wind turbine support structure, including a decentralized hydrogen production platform. Looking into future developments, a 15 MW reference turbine was selected for a water depth of 45 m in the F3 sector of the North Sea.

H2SEA carries out assessment on monopiles for H2 WTG

To obtain platform mass, dimensions, and rotational inertia, all required systems were selected, listed and an optimised platform layout and mass estimation were made. For the design of the platform support beams, gravitational loads and extreme wind gust loads were taken into account. The selection of the support structure concept was performed using a multi-criteria analysis.

For fatigue assessment, an analytical fully dynamical model was constructed in Maple. The structure was simulated by the equations of motions, including airy wave force, rotor damping, topside and platform mass and rotational inertia, embedded length, and homogeneous soil stiffness. The Maple model was used to simulate dynamic behavior of both structures, determine first and second natural frequency, and present displacements and overturning moments in these two mode shapes. 

Finally, a fatigue damage calculation including 500 combinations of wave height and period is performed, for a 25-year lifetime.
