The REFHYNE project is about to complete the construction of Europe’s largest PEM electrolyser. The starting shot for the production of green hydrogen on an industrial scale was fired on 2 July 2021.

The new electrolyser will have a peak power of 10 megawatts and will be able to produce up to 1,300 tonnes of hydrogen per year. This corresponds to the amount of hydrogen needed to drive about 16 million kilometres on a hydrogen bus, a distance equivalent to travelling around the globe 40 times.

With the installation of impressively large Venturi roofs by Frijns, the construction of the REFHYNE plant has reached another important milestone. .

Three special cranes were needed to hoist the two so-called Venturi roofs onto the system. The two modules cover a roof area of 25 by 18.5 metres and weigh 46 tonnes. The roof construction ensures that the production area is ventilated in an environmentally friendly and resource-saving way. There is no need for mechanical ventilation.

Frijns was responsible for supplying and assembling all the steelwork for the substructure, landings, handrails and Venturi roofs.

The roofs were covered with Kalzip sheeting and completely finished off with flashing.

Total tonnage approx. 90 tons
