All the units designed can process the same CO2 input, from the 700 Nm 3 /h produced by the biogas plant on average. However, due to the different process efficiencies and range of the engines, the distance that can be driven with the same CO22 input is significantly different for the four processes. The various distances that can be driven with the products of the four process configurations is shown in figure . The range for FCEV is similar for methanol and methane storage, with approximately 400 km per hour of CO2 production. The driven range with BEV is much higher, with ca. 800 km for the methanol storage and 1180 km for methane storage. Hence, the larger cost for the equipment required to store electricity than H2 is largely compensated by the higher final output in terms of final output. This reconfirms what elucidated in the previous sections and what described in literature .
