was determined as 10 to 20% for with fossile gasoline operated vehicles with internal combustion engine, as 15 to 29% for with fossile gasoline operated full electric hybrid vehicles with internal combustion engine, as 13 to 25% for with fossile Diesel operated vehicles with internal combustion engine, as 12 to 21% for with fossile CNG operated vehicles with internal combustion engine, as 20 to 29% for fuel cell vehicles (e.g. fossile hydrogen or methanol) and as 59 to 80% for battery electric vehicles. In German study "Agora Energiewende" different drive technologies by using renewable electricity for fuel production were examined and a WTW efficiency of 13% for vehicles with internal combustion engine (operated with synthetic fuel like OME), 26% for fuel cell vehicles (operated with hydrogen) and 69% for battery electric vehicles was determined. If renewable hydrogen is used the Well-to-Wheel efficiency for a hydrogen fuel cell car amounts to about 14 to 30%. If renewable e-Methanol is produced from directly available CO2 the Well-to-Wheel efficiency amounts to about 11 to 21% for a vehicle with internal combustion engine which is operated with this e-Methanol and to about 18 to 29% for a fuel cell vehicle which is operated with this e-Methanol. If renewable e-Methanol is produced from CO2 of Direct Air Capture the Well-to-Wheel efficiency amounts to about 9 to 19% for a vehicle with internal combustion engine which is operated with this e-Methanol and to about 15 to 26% for a fuel cell vehicle which is operated with this e-Methanol (status of 2021). Cost comparison Methanol economy vs. Hydrogen economy Fuel costs: Methanol is cheaper than hydrogen. For large amounts (tank) price for fossile methanol is about 0.3 to 0.6 USD/L. One liter of Methanol has the same energy content as 0.13 kg hydrogen. Price for 0.13 kg of fossile hydrogen is currently about 1.2 to 1.3 USD for large amounts (about 9.5 USD/kg at hydrogen refuelling stations). For middle scale amounts (delivery in IBC container with 1000 L methanol) price for fossile methanol is usually about 0.5 to 0.7 USD/L, for biomethanol about 0.7 to 2.0 USD/L and for e-Methanol from CO2 about 0.8 to 2.0 USD/L plus deposit for IBC container. For middle scale amounts of hydrogen (bundle of gas cylinders) price for 0.13 kg of fossile hydrogen is usually about 5 to 12 USD plus rental fee for the cylinders. The significantly higher price for
