This paper presents near-term and forward looking paths to produce solar fuels using concentrated solar energy as the source of process heat to drive thermochemical processes. Solar gasification of biomass is presented as an important stepping stone toward the goal of thermochemical metal oxide redox cycles to split water and carbon dioxide.7 pagesPDFen© 2015 University of PretoriaPetroleum-derived fuelsRenewable solar fuelsAnthropogenic emissionsSolar fuelsConcentrated solar energyPresentation
