The objective of the AlkaliBoost project is to develop and test new alkaline water electrolyzer designs that allow operation at higher current densities, reducing the effective costs of the electrochemical stack to less than 100 €/kW. The focus is on minimizing the ohmic resistance, which in addition to the diaphragm resistance is mainly determined by the structure of the electrodes and the gas bubbles formed. If this goal is achieved, it may be possible to reduce the investment costs for large-scale water electrolysis (1 GW+) to a level of 350 €/kW in 2030, making it comparable to SMR in terms of investment costs.
