The widespread use of fossil fuels since the Industrial Revolution has caused CO2 concentrations in the atmosphere to rise exponentially, leading to severe ecological and social challenges. Large-scale renewable energy adoption is key to reducing carbon emissions, while sources like solar and wind are intermittent and variable. As a result, they require large-scale, long-duration energy storage systems. The low-temperature CO2 electrolyser addresses this issue by using renewable electricity to convert CO2 into fuels and chemicals, enabling both energy storage and CO2 valorization, and closing the loop on anthropogenic CO2 emissions...
