Abstract

Methanol is a promising liquid energy carrier for the storage of renewable energy. The comparison with hydrogen shows a lower total energy efficiency for methanol. But methanol is easy to handle within the existing transport and storage capacities of the petrol industry. Therefore it causes low investment costs for the infrastructure of a global renewable energy network. For the storage of small amounts of energy like in individual traffic and for the distribution of energy in low populated regions methanol is even the most efficient alternative. Beside hydrogen, a basic component for the synthesis of methanol is CO2. The recovery of CO2 from atmosphere will avoid an infrastructure for CO2-transport to the place where methanol is generated. With solar energy as the energy source a lower energy demand for the recovery of CO2 from atmosphere than from combustion fluegases can be achieved. An integration of biomass as basic product for the synthesis of methanol improves the conversion efficiency from solar energy to methanol.

    Fossil fuels are the primary energy source for the ever-growing transportation sector, and their consumption has led to an increasing demand on energy supplies and has raised concerns about harmful CO2 emissions. As a clean-burning renewable fuel [1], methanol has been widely used in internal combustion engines both as a neat fuel, in blends, and as an additive because of its tendency to lower soot and NOx emissions [2]. Engine studies [3–5] have explored the effect of methanol addition on exhaust emissions and the auto-ignition characteristics of fuels.

    These include CO2 capture, electrolysis of CO2 and H2O, and fuel synthesis [252]. The electrolysis of CO2 and H2O has been carried out in solid oxide cells to produce syngas [268–272]. However, the process had the disadvantage of producing CO2 and O2 together in the anode compartment of the electrolysis cell, thus, there was a need for subsequent gas-phase separation [273,274].
