The system stores and supplies electricity as a battery and, when charged, splits water into hydrogen and oxygen as an electrolyser. The technology is operational at a large-scale industrial gas power plant in the Netherlands and its commercial deployment is scheduled for 2024.
The first industrial-scale Battolyser system was installed at RWE’s Magnum power plant in the Netherlands earlier this year.
Battolyser says its technology is a good match for the intermittency of renewable energy sources like wind and solar. Compared with conventional electrolysers, the Battolyser can safely switch on and off instantly, allowing customers to produce affordable green hydrogen when power prices are beneficial or when renewable power is available.
The InvestEU programme that supports this EIB investment aims to mobilise over €372 billion in additional investment for EU policy priorities in the 2021–2027 period.
“This technology has the potential to really change how we manage our energy,” said EIB vice-president Kris Peeters. He pointed out that, while solar panels and wind farms are sometimes shut down or throttled to avoid overproduction, the Battolyser allows excess energy to be stored or converted into green hydrogen.
The technology was spun out from Delft University of Technology in 2018 and won investment in 2020 from Koolen Industries. Recently, Innovation Industries and Global Cleantech Capital have also invested in Battolyser.
