Delft University of Technology spin-off Battolyser Systems has installed its first industrial-scale Battolyser at RWE’s Magnum power plant in the Netherlands.
The Magnum power plant will use the hydrogen produced by the Battolyser system to cool its generators.
The project was realised thanks to a grant from the Wadden Fund and the consortium partners Vattenfall, Orsted, Yara, BASF and Pronton Ventures.
RWE joined the consortium when the power plant was acquired from Vattenfall.
A Battolyser is a combination of a battery and an electrolyser in one device.
As soon as the system’s battery is charged, the Battolyser can use the excess electricity to split water into hydrogen and oxygen.
The hydrogen can be used for industrial applications, for instance, to reduce greenhouse gas emissions.
If there are shortages on the grid, a Battolyser can also deliver the stored electricity back to the grid.
This makes the produced hydrogen greener and at the same time cheaper.
The setup at RWE will be used to simulate long-term volatile price scenarios.
When electricity prices remain low, the Battolyser will continue to charge and produce hydrogen and when prices rise, the Battolyser will immediately stop producing hydrogen and sell the stored electricity.
“It is a logical choice for us to invest with our consortium partners in the first industrial-scale Battolyser system.
“We are increasingly investing in renewable energy sources and see hydrogen as an essential link to the energy transition,” said Marinus Tabak, Head of Central Asset Management at RWE.
He added: “The technology of the Battolyser system enables a sustainable and more efficient energy system.
“This way we can reduce the dependency on fossil fuels and accelerate the transition to a more sustainable and efficient energy supply.”
