Practice What You Preach: H2sea Team Members Drive Hydrogen

H2sea CEO Edwin van Drunen and Marketing Director Marika van Pol refuelling their hydrogen-powered vehicles at hydrogen refuelling stations in the Netherlands.

At H2sea, we don’t just work on the hydrogen transition – we actively participate in it. 

Both H2sea founder and CEO Edwin van Drunen and Marketing Director Marika van Pol drive hydrogen-powered vehicles in their daily lives, reflecting their confidence in hydrogen as an important part of the future energy mix.

Together, they have already driven more than 80,000 kilometres on hydrogen, gaining valuable first-hand experience with hydrogen mobility in everyday use.

As professionals working in the hydrogen sector, we see every day how hydrogen can contribute to decarbonising industry, supporting renewable energy integration, and providing solutions for sectors that are difficult to electrify. We believe hydrogen will play a significant role in future energy systems, not only as a feedstock and energy carrier for industrial applications, but also in transportation.

The hydrogen mobility infrastructure in the Netherlands continues to expand. Today, hydrogen refuelling stations are available in almost all major cities. Edwin regularly refuels in Rotterdam, The Hague, Utrecht and Amsterdam, while Marika uses stations in Breda, Dordrecht, Eindhoven and Roosendaal. Refuelling takes only about two minutes – comparable to filling up a conventional petrol vehicle – making zero-emission driving both practical and convenient. 

For us, this is about more than just technology. At H2sea, we believe in leading by example. The hydrogen transition starts with our own choices.

H2sea awarded engineering role in OMG-H2 project

Impression of the Offshore Midsize Green Hydrogen (OMG-H2) Platform, a concept for green hydrogen production integrated with offshore wind energy

Green hydrogen developer H2DO (Hydrogen of Dutch Origin) has awarded part of the engineering scope for the OMG-H2 (Offshore Midsized Green) Hydrogen Feasibility and Concept Study to H2sea.

The OMG-H2 project is supported through a grant awarded under the Dutch Government’s Topsector Energy (TSE) programme for Hydrogen and Green Chemistry.

The feasibility study focuses on the conceptual design, installation and operation of a 30–50 MW offshore green hydrogen production facility in the Dutch North Sea.

H2sea will start with the Hydrogen Facility Design work package, focusing on subsystem engineering. The objective of this work package is to mature subsystem analysis to an acceptable Technology Readiness Level (TRL) and integrate the findings into the overall installation design.

This will support the technical feasibility and robustness of the offshore hydrogen concept, while also helping to identify scalability potential and support future project decision-making.

As a worldwide frontrunner in offshore hydrogen engineering, H2sea will bring its extensive expertise and lessons learned from previous offshore hydrogen projects into the OMG-H2 study, supporting the further development of scalable and practical offshore hydrogen solutions for the North Sea.

Strong Interest and Royal Presence at World Hydrogen Summit

The H2sea team posing at the H2sea exhibition stand during the World Hydrogen Summit in Rotterdam, showcasing offshore hydrogen solutions and onshore hydrogen modules.

H2sea experienced a strong first exhibition day at the World Hydrogen Summit in Rotterdam, with strong interest in both its offshore hydrogen concepts and recently introduced onshore hydrogen modules.

A special highlight of the day was the presence of His Majesty King Willem-Alexander of the Netherlands at the Japan Pavilion, located opposite the H2sea stand, where H2sea was invited to participate in the seminar programme focused on international hydrogen cooperation and innovation.

In the evening, H2sea CEO Edwin van Drunen and CTO Tom Evertse attended an official reception hosted by the Japanese Ambassador for a select group of invited World Hydrogen Summit guests, underlining the importance of international collaboration in accelerating the hydrogen economy.

H2sea pitches Solution to Energy Trilemma at WindEurope 2026

H2sea pitches solution for Energy Trilemma at WindEurope 2026

At WindEurope 2026 in Madrid, H2sea attracted strong interest at the Netherlands Pavilion, where Tom Evertse delivered a sharp pitch focused on the energy trilemma: balancing sustainability, affordability, and energy security.

As offshore wind scales rapidly, system limitations are becoming clear. Grid congestion and curtailment are leading to lost renewable energy, while large parts of the energy system still depend on fossil-based fuels. Electricity alone is not enough to drive the transition.

Rather than treating offshore wind as a standalone power source, Tom positioned it as a cornerstone of an integrated energy system—one that connects electrons and molecules, and unlocks the full value of renewable generation.

The takeaway: the energy is already there. The opportunity lies in using it more effectively to solve the energy trilemma.
H2sea already delivers these solutions—integrating offshore wind with hydrogen production, offering offshore hydrogen platforms across 50–1000 MW to onshore hydrogen production modules.

H2sea introduces Onshore Hydrogen Modules in Tokyo

Onshore hydrogen production modules

This week, H2sea is introducing its new onshore hydrogen modules in Tokyo.

With this step, H2sea is extending its portfolio of offshore hydrogen platforms with scalable onshore solutions for industrial and urban applications. The hydrogen modules are designed as flexible building blocks, allowing projects to be tailored to specific production capacities and site conditions.

During their visit to Tokyo, CEO Edwin van Drunen and CTO Tom Evertse are holding several meetings with Japanese utilities at the Tokyo Innovation Base, followed by the EU Business Mission programme and participation in Smart Energy Week.

“Japan is the perfect market for introducing our onshore hydrogen modules,” says Edwin van Drunen. “As a highly innovative and technology-driven energy market, Japan is actively investing in hydrogen as a cornerstone of its energy transition and is looking for high-quality, scalable solutions. The growing demand for hydrogen applications on land makes it a strong match for H2sea’s modular hydrogen production solutions.”

With this development, H2sea continues to build on its mission to accelerate the large-scale deployment of hydrogen production solutions that support the global energy transition.
