The hydrogen battery that can store power and produce hydrogen at highly efficient rates

Page last modified
August 4 2023

Battolyser Systems develops and manufactures an integrated battery/electrolyser product, the Battolyser® that can store electricity and produce hydrogen from renewable power to balance societal demand.

A Battolyser® offers a dual-purpose energy storage solution with a combined battery and electrolyser function that unlocks a complete new business model. This enables the use of only low-cost electricity or electricity from renewables; while in hours with high electricity price hours, no hydrogen is produced but rather the battery is discharged selling electrons. This allows for the production of hydrogen that is both affordable and truly "green". 

It is a new product category with breakthrough flexibility, robustness, efficiency using only abundant materials and easy to recycle.

Pro/con

Flexibility - Battolyser® can instantly switch back and forth between charging and discharging and can perfectly follow a renewables load curve
Efficient - Stack is 80-90% energy efficient
Sustainable - Technology is using only abundant available materials
Robust - Battery allows deep discharging and no risk of overcharging. The "overcharge" is what causes electrolysis
Versatile - System can arbitrage between power and hydrogen markets
Footprint - Due to the combined battery / electrolyser functionality, a Battolyser® has a larger footprint than a single electrolyser or battery system
