Producing syngas
If a mixture of CO2 and H2O is fed to the electrolyzer, the result is a mixture of H2 and CO, which is called syngas. Syngas is widely used in the chemical industry and can be used to produce synthetic fuels.
The process is driven by electricity and heat.
High temperature electrolysis
High temperature electrolysis uses heat to evaporate water, reducing the amount of heat electricity required to split the steam into hydrogen and oxygen. The heat can be obtained from various sources, for instance combined heat and power plants.
Traditional electrolysis plants operating at lower temperatures are less efficient, as a substantial amount of electricity is required to split water.
