Van Staveren and Tolsma-Grisnich are set to launch the STG-H2UB sustainable energy project on 1 July

Van Staveren and Tolsma-Grisnich are opening a zero-emission energy hub on Wednesday 1 July. STG-H2UB, as the project is called, has been jointly developed by the two companies on Tolsma-Grisnich’s site on Cavalier in Emmeloord.
STG-H2UB has been developed in close collaboration between refuelling and charging station operator Van Staveren and Tolsma-Grisnich, a manufacturer of systems for the storage, processing and packaging of arable crops, particularly potatoes, onions and carrots. The hub, which operates completely emission-free, combines multiple technologies into a single integrated energy system and is set to supply Tolsma-Grisnich with sustainable electricity. The energy hub comprises hydrogen technology, three battery storage systems of 220 kWh each, 1,200 solar panels, a grid connection of three times 80 A and an energy management system (EMS) that controls and optimises all energy flows.
Hydrogen trailer
Van Staveren recently installed a hydrogen trailer for the project. This will be responsible for the supply, storage and buffering of hydrogen on site. The hydrogen generator converts hydrogen into electricity, without combustion or emissions and with high efficiency. Once STG-H2UB is commissioned, it will supply energy to the Tolsma-Grinich office, the production area, the heat pumps and the vehicle charging station.
“Together, we are demonstrating how smart technologies can contribute to a future-proof energy supply,” said Van Staveren.
The opening will take place on 1 July and will be performed by Jitha van Staveren of Van Staveren and Dim Jan de Visser of Tolsma-Grinich. Van Staveren operates 35 petrol stations in the centre of the Netherlands: sixteen under its own Tank S brand, and the remaining nineteen under the Shell banner.
