Electrolyzer efficiently converts CO2 into renewable propane fuel
There’s no clear indication whether that would require some CO2 or a concentrated atmosphere of CO2 without O2. Extracting CO2 from the atmosphere at 0.4% is expensive.<p>If this is meant to use concentrated CO2 coming out from a furnace, would that need to be local, piped in over a long distance, or using bottles? Are there use cases where we must burn propane because we can’t replace that process with electricity?
