Challenge and concept
The energy transition in Germany is in full swing. The associated expansion of wind power and photovoltaics will result in a considerably increasing rise of power available from fluctuating energy sources. With electrochemical syntheses the temporarily available excess in the electrical grid can be used for energy-intensive manufacturing operations.
When surplus electricity is used to balance out peaks of power supply to the grid as a consequence of intermittent, regenerative power generation, basic chemicals can be synthesized cost-effictively.
We investigate and evaluate gas diffusion electrodes for electrosynthesis in order to produce chemicals on site and to offset power peaks caused by fluctuating regenerative electricity supply, by converting flexibly the electric energy into basic chemicals.
To develop the process, scalable and adaptable continuous flow cells are available that enable a wide range of development tests by changing the gas diffusion layer.
