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 exhibitor at WindEurope 2026 Madrid

H2sea exhibiting at WindEurope 2026 Madrid - Dutch Pavilion stand g-G20

From 21–23 April, H2sea will be present at WindEurope 2026 in Madrid. You can find us in the Innovation Quarter of the Dutch Pavilion (stand 9-G20).

We will be showcasing our green hydrogen solutions across the complete value chain, ranging from our newly introduced onshore hydrogen production modules to complete offshore hydrogen platforms.

Our approach ensures a balanced and integrated system design, with a strong focus on balance of stack engineering. In addition, we address key system interfaces such as pipeline integration, grid stabilisation and off-grid solutions.

On behalf of H2sea ,Tom Evertse, Technical Consultant, will be present at our booth. If you are looking for expertise for your hydrogen project, feel free to reach out via t.evertse@H2sea.n to connect or schedule a meeting in advance.

Looking forward to meet you in Madrid!

H2sea exhibits at Smart Energy Week Tokyo

H2sea exhibits at Smart Energy Week Tokyo

H2sea is proud to participate in the Smart Energy Week in Tokyo as part of the EU Business Hub Japan mission.

Taking place at Tokyo Big Sight from 17-19 March, this major 3-day event brings together around 1,600 exhibitors and 70,000 visitors, making it one of Asia’s most important green energy and hydrogen exhibitions.

H2sea is represented on site by CEO Edwin van Drunen and CTO Tom Evertse, showcasing its extended product portfolio for both onshore hydrogen modules and offshore hydrogen platforms at the EU Pavilion.

“Today marks the final day of the exhibition. Smart Energy Week has been a valuable experience, opening the door to promising new partnerships and future collaboration. We would like to thank the EU Business Hub Japan team for their excellent organisation and support throughout the mission,” said Edwin van Drunen.

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.

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.
