Dutch climate tech company Battolyser Systems has secured a €40mn ($42mn) financing deal from the European Investment Bank (EIB) to scale up production of its integrated electricity storage and electrolyser solution.
The company will be able to bring its Rotterdam factory towards mass production through the funding, Battolyser said.
Battolyser's technology combines alkaline electrolyser with charged electrodes that allow the system to behave like a battery, chief executive Mattijs Slee told Argus on the sidelines of the World Hydrogen Congress in Rotterdam.
The technology increases flexibility for renewable power producers to follow the economics of the power market and use the intermittency of renewable power generation in their favour, according to Slee. This reduces the need for power purchase agreements, Slee said, because operators can decide when its more profitable to sell energy back to the grid or when it would be better used in production of hydrogen.
Battolyser, thanks to its system's on-and-off feature, helps operators be aligned with the EU's requirement of temporal correlation for renewable hydrogen production, he said.
"We are introducing a new business model as well as a new technology," Slee said.
Because excess energy can be stored or converted into renewable hydrogen, Battolyser "reduces what is called the cost of ‘missed energy' in our grid," said EIB's vice-president Kris Peeters.
All the materials used in Battolyser's product come from Europe, Peeters added, which aligns with the EU's goal of reducing its dependency from resources from outside, he said.
Battolyser's technology is currently in use at a large-scale Dutch industrial gas power plant and wider commercialisation should start from next year.
The company is developing its product in three sizes. A 250kW product is in construction and orders for this have already been placed, while a 500kW model is under development. They will be ready for delivery next year. It is also doing research for a 1MW model that is scheduled for delivery in 2025.
