Modelling of hydrogen production by alkaline water electrolysis powered by an unstable power source

Popis výsledku v původním jazyce

Alkaline water electrolysis (AWE) is the oldest and most developed water electrolysis technology widely used around the world. Research is focused on further development of AWE. One of the research approaches is mathematical modelling. It can be used to predict behavior of an electrolyser in dependence on the operating conditions and power supply. The relation between minimum operating requirements and the power output of the unstable power source must be assessed to estimate the electrolyser size for maximal utilization of both the produced electricity and the electrolyser. A simple mathematical model for AWE powered from an unstable power source was developed. The electrolyser has variable size and operational settings. Power inputs for the model are a photovoltaic power-plant and energy recuperated by braking trains. The output of the model is hydrogen production, total time of production and percentual load in time. These results help estimate the ideal electrolyser size used for given power source. Acknowledgment: This work was supported from the grant of Specific university research – grant No. A2_FCHT_2022_001. This project is financed by the Technology Agency of the Czech Republic under grant TO01000324, in the frame of the KAPPA programme, with funding from EEA Grants and Norway Grants.
