The company H2Flexx was formed from the merger of the Dutch companies H2Fuel and HydroFlex. It has scheduled its market launch for May 7, 2026. The focus is on the product H2Easy: a patented powder based on sodium borohydride (NaBH₄), which, according to the company, can safely store, transport, and release hydrogen on-site. According to H2Flexx, the energy density is 216 kilograms of hydrogen per tonne. The powder is intended to be handled at ambient temperature and low pressure.
Cycle between H2Easy and H2Spent
After hydrogen release, the residual material H2Spent remains, according to the company. This is to be reprocessed into H2Easy through a mechanical process. The company states that this process requires significantly less energy than established processes like the Brown-Schlesinger process. This creates a closed cycle that becomes more economical with increasing scale.
Market approach: Alternative to grid connection
H2Flexx positions the product as a response to grid bottlenecks in the Netherlands. Industrial parks, hospitals, distribution centers, data centers, and agricultural operations can thus switch their energy supply without having to wait for a new grid connection. The company also sees H2Easy as a storage option for weeks or months without energy loss – unlike batteries, which are only suitable for hourly buffering.
“The Netherlands has a power grid that can no longer keep up. Companies wait years for a connection, while the energy transition has no time to lose. H2Easy solves this problem: hydrogen as a powder, usable without grid expansion, scalable from one location to thousands,” says Sander Castel, CCO of H2Flexx and founder of HydroFlex.
International pilot projects planned
According to the company, initial pilot projects are underway. Strategic discussions with market participants in Europe, the Middle East, and India are ongoing. For markets with low electricity prices like India and the Middle East, H2Flexx sees potential in local production of H2Easy followed by export to import regions such as the EU.
“The merger brings together two complementary paths: deep technological development and practical application. By combining knowledge, patents, and experience, we accelerate not only our own development but also that of the hydrogen economy in the Netherlands and beyond,” says Koos-Jan van Brouwershaven, CEO of H2Flexx and H2Fuel.
