A tulip forcing company in the Netherlands is breaking new ground in clean energy.
Rainbow Colors, based in Andijk in North Holland, has installed a solid oxide electrolyser to produce green hydrogen. Project partners say it is the first agricultural business in the world to apply this advanced technology. With a capacity of one megawatt, the system is also among the largest operational solid oxide electrolysers currently in use, marking a major step forward for hydrogen development in North Holland North.
The project is being delivered in partnership with Danish technology firm Dynelectro, while Dutch company Ekinetix is responsible for building the required infrastructure. The installation forms part of the regional programme Fieldlab Waterstof in de Agri, which focuses on creating a hydrogen network tailored to the agricultural sector.
Rainbow Colors has been involved in the initiative since 2023 as a pilot site for hydrogen production. By using surplus solar energy along with battery storage, the company aims to ensure a steady and reliable supply of hydrogen. The technology partners explain that solid oxide electrolysers are more efficient and experience less wear than conventional systems. Their longer operational life and improved performance are expected to lower the overall cost of hydrogen production. The system also offers a practical response to grid congestion, while increasing access to clean energy within the region.
The installation is described as pioneering not only because it is the first of its kind in agriculture, but also because it ranks as the third largest operational unit of this type worldwide. It is expected to serve as a model for other agricultural businesses seeking solutions to high energy costs and limited grid capacity.
Beau Broen, project leader at New Energy Coalition and coordinator of the hydrogen pilot projects within Fieldlab Waterstof in de Agri, said: "It is impressive to see how international innovation comes together in this project. By implementing Dynelectro's electrolyser at project partner Rainbow Colors, the region is taking an important step towards decentralized hydrogen production. It also provides an economic boost by making affordable green hydrogen available. The project underlines the innovative role North Holland North plays in the energy transition."
With this facility now operational, locally produced green hydrogen becomes available in the Netherlands, helping to address the balance between supply and demand. By using surplus renewable electricity, hydrogen can be produced for less than ten euros per kilogram and used locally. The wider programme brings together businesses and knowledge institutions across North Holland North, positioning the province as a leading hydrogen region and showing that emission free energy solutions are already within reach for agriculture.
