Hysolar electrolyser on KWR site will supply yearly 250 tons of green hydrogen

Producing and distributing hydrogen with locally generated electricity

Starting next year, the 3 million euro installation on the KWR site will split water into oxygen and hydrogen, producing 250 tons of green hydrogen a year. Solar panels on-site will power the installation with green energy. The residual heat will be supplied to a nearby industrial laundry.

Supply is welcome

The customers for green hydrogen are ready for this supply. In Nieuwegein, on the site of the constructing company Jos Scholman, Hysolar built a filling tank station, which was officially opened on 8 October. The filling station mainly aims at heavy vehicles. Currently, the filling station supplies green hydrogen from HyGear in Arnhem, but Hysolar will produce its green hydrogen at the KWR site next year. Jos Boere, director of Allied Waters: ‘We will produce and distribute hydrogen locally, using locally generated electricity. We can supply 250 tonnes of hydrogen a year at full capacity: enough to power 750 cars or 25 buses. But inland navigation is also a significant potential market, where we can contribute to green transportation’.

Allied Waters

Hysolar is an initiative of KWR spin-off Allied Waters and contracting firm Jos Scholman, reinforced with strategic partners Van Kessel Groep and Scholt Energy. The green hydrogen filling station in Nieuwegein is the first in the Province of Utrecht. The Province of Utrecht aims to take a leadership role and set up a network of hydrogen hubs for mobility and logistics. The ‘Covenant on Hydrogen in Mobility for the Province of Utrecht’, developed by the Province and with KWR is the first step. The ambition is to build 5 to 10 more green hydrogen filling station by 2025.

Hydrogen and disseminating knowledge

Hysolar Innovation & Advice takes developments beyond the production of hydrogen. Hysolar aims to disseminate the knowledge acquired in Nieuwegein and generate new technologies,’ says Boere.  For example, we are investigating the possibility of producing water from purified effluent from sewage plants instead of demineralised water or biogas from sludge fermentation. All options that are interesting for the water sector.


The electrolyser is part of the LIFE NEW HYTS project, which has received funding from the LIFE Programme of the European Union, under Grant Agreement LIFE20 CCM/NL/001664
