It says the Faradaic efficiency is 90%, which unfortunately is not the total energy efficiency. Total energy efficiency also includes thermodynamic and practical constraints. https://en.wikipedia.org/wiki/Faraday_efficiency#Faradaic_loss_vs._voltage_and_energy_efficiency https://en.wikipedia.org/wiki/Faraday_efficiency#Faradaic_lo... However that's still a great figure. I'm in awe that a carbon-substrate catalyst converts CO2 so well without degrading itself.
