Scaling and heating will drive low-temperature CO<sub>2</sub> electrolysers to operate at higher temperatures
Nature Energy, Published online: 28 April 2025; doi:10.1038/s41560-025-01745-5Low-temperature CO2 electrolysers are often tested at ambient temperature, yet this may not be optimal for larger-scale systems. In this Perspective Pelzer et al. argue that heat generation, due to the energy inefficiency of electrolysers, will favour elevated operating temperatures of 40–70 °C.
