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.
Green hydrogen company H2SEA has completed a study showing that the costs for ESS (Energy Storage Systems) on offshore hydrogen platforms can be reduced by 75%.
H2SEA investigated different cost reduction scenarios for offshore green hydrogen production with a connection to an off-grid windfarm for the power supply.
Due to an extensive network of technology partners, H2SEA has access to accurate data of hydrogen building blocks. Different configurations have been evaluated, taking both grid stability and cost implications in mind.
One of the cost reduction strategies involves the integration of different transformers optimising space and cost per megavolt-amperes/m2, and the use of a smart ESS.
Further, a different configuration of the energy storage and electrolyser system can reduce infrastructure requirements.
One of the configurations that H2SEA has modelled, leads to a 75% decrease in costs of the ESS, which is quite a significant part of CAPEX investment, making green offshore hydrogen production a feasible economic option as renewable fuel in the future.
H2SEA is exhibiting on technology trade fair & conference ZIE 2024 in Rotterdam on 4 April.
The event is set up to connect high tech companies with fabrication industry, knowledge institutes and government in the province of South Holland, the Netherlands.
Together the different organisations can play a key role in the field of digitalization, the energy transition and the circular economy. One of the focal point of the ZIE 2024 summit is hydrogen.

Edwin van Drunen, MD of H2SEA, was interviewed on Dutch television for the program Building the Future about the possibilities of hydrogen and how this can play an important part in the Energy Transition.
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.

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.
