In this communication, we give the following corrigendum to the original paper, “A comparison between renewable transport fuels that can supplement or replace biofuels in a 100% renewable energy system” , to correct some typos and a figure which could mislead the readers: • Firstly, the incorrect figure was inserted as Fig. 9. The existing Fig. 9 was part of the supplementary information and it represents the hydrogenation of carbon dioxide using co-electrolysis. The correct Fig. 9 is provided below, which is meant to represent the hydrogenation of carbon dioxide using steam electrolysis. • Furthermore, the stoichiometric equations provided contain two errors relating to the energy densities provided. Firstly, the energy density used for methane in the calculations was 890 kJ/mol and not the 800 kJ/mol presented in the paper. The energy density of methane can vary across this range , but the issue is that the energy density assumed in the calculations is 890 kJ/mol, and not the 800 kJ/mol reported. • Finally, the energy density reported here for carbon monoxide is incorrect. It should be 283 kJ/mol, instead of the 393 kJ/mol reported. Again, the correct energy density is used in the calculations, which is 283 kJ/mol, so this is a reporting error.
