New electrolysis technology paves the way for decentralized hydrogen production

Nordic Hydrogen has developed a new electrolysis prototype that makes it possible to produce green hydrogen locally.

It may be a small plant, but it could have a big impact on the green transition. Nordic Hydrogen has developed and tested a new electrolysis prototype that demonstrates the potential for decentralized hydrogen production close to the source of renewable energy.

The new technology takes up less space and weighs less than conventional electrolysis plants and is developed with fewer materials. Yet it delivers hydrogen in both quantity and purity that meets the technical requirements – and this opens up new opportunities for local production outside the central electricity grid.

- We want to make it easier to produce green hydrogen where the power is – outside the central grid and large, central plants, says Sarah Groot Shapel, founder and CEO of Nordic Hydrogen.

While many players in the hydrogen sector focus on large, central plants, Nordic Hydrogen is going in a different direction: decentralized, mobile and scalable systems.  

And although the technology is intended for offshore use in the long term – for example integrated into or at wind turbine towers – it is assessed that container-based plants close to energy sources on land are a more realistic solution in the short term.

With the prototype and the upcoming 150 kW plant, Nordic Hydrogen is well on its way to making hydrogen an integrated part of the flexible and decentralized energy system, where surplus electricity gains new value as green hydrogen.

The first version has a capacity of 2 kW and was developed in the innovation project Tower-2-X in collaboration with Force Technology and facilitated by Energy Cluster Denmark. The project is supported by the EU and the Danish Business Development Agency.

The prototype has been crucial in documenting the technology and paving the way for upscaling. The next step is a 150 kW plant that matches the needs of smaller electricity producers with surplus energy.

Nordic Hydrogen has already sought support from Innovation Fund Norway and Mission Green Fuels to realize this next phase.

- Our ambition is to make green hydrogen production available to more players. This does not require large factories, but a new approach with small, flexible and scalable solutions, says Sarah Groot Shapel.
