Solar Fuels

Solar Fuels

A future energy economy can hardly be envisioned without the use of gaseous or liquid fuels. Fuels as chemical energy carriers provide the advantage of high energy content, easy transport and storage, as well as reasonable conversion efficiencies. In addition, fuels generated from renewable but discontinuous primary energy sources as e.g. solar and wind energy (solar fuels, for example) allow balancing the fluctuations in the electric power production from these sources by easy storage and transport.

Therefore, specifically designed fuels (designer fuels) can be more frequently used for power trains and transport. However, fuel production from renewable primary energy sources and their utilisation offer so far a mostly unsolved challenge for a novel energy system.

The given scientific and engineering limitations of an efficient and economic solar fuel cycle define the research objectives of this research field:

  • • The efficient production of H2 from discontinuously available primary energy carrier
  • • The efficient conversion of CO2 with H2 to methanol and related hydrocarbons
  • • The development of adapted combustion and converter technologies
