Construction of hydrogen plant H2 Hollandia starts 

The H2 Hollandia project has reached financial close. This means that all contracts have been signed and all financing arrangements are in place. Construction of the hydrogen plant can now officially begin. 

H2 Hollandia directly connects the large-scale solar park Vloeivelden Hollandia to an electrolyser. The electrolyser will produce green hydrogen without placing an extra burden on the electricity grid. When completed in 2026, it will be the largest operational electrolyser in the Netherlands producing fully green hydrogen. The project has received €11.5 million in funding from GroenvermogenNL through the DEI+ scheme. 

“H₂ Hollandia demonstrates that green hydrogen not only helps to solve grid congestion, but also creates opportunities for sustainable growth and a future-proof energy system. This is real impact, and I’m proud that GroenvermogenNL has been able to contribute.” 

Marjan Oudeman, Chair of the Board, GroenvermogenNL 

Sustainable mobility and industry benefit 

The green hydrogen will be purchased by an industrial gas distributor and used for sustainable mobility and industry in the region. The system compresses the hydrogen to high pressure, after which it is collected by the distributor using tube trailers and delivered to end users. 

With H2 Hollandia, Novar and Avitec aim to bridge the gap between hydrogen supply and demand by making hydrogen available locally and accelerating the development of a decentralised hydrogen economy. 

“This project is a blueprint for how we can handle local sustainable energy production in the Netherlands. By making hydrogen available regionally, we can, for example, also make heavy transport more sustainable.” 

Ben Timmermans, Avitec 

Smart energy solution to grid congestion 

At the heart of H2 Hollandia is a 5 MW electrolyser connected to the 115 MWp Vloeivelden Hollandia solar park. The system will produce around 300,000 kilograms of green hydrogen per year from solar power. Because the electrolyser will share the same grid connection as the solar park, it will help prevent further overloading of the electricity network — a growing issue in the Netherlands. 

 Due to limited local grid capacity, the existing solar park cannot always feed all generated electricity into the grid during very sunny periods. Thanks to H2 Hollandia, this surplus energy can now be used to produce green hydrogen. This makes the solar park’s energy use much more efficient and contributes to a more stable and sustainable energy supply.
