Solar-driven pyrolysis and gasification measurements were conducted directly irradiating the samples in a 7 kW e high flux solar simulator and the released gases H 2 , CO, CO 2 and CH 4 and the sample temperature were continuously monitored. Solar-driven experiments showed that H 2 and CO evolved as important product gases demonstrating the high quality of syngas production for the three feedstocks. Straw is the more suitable feedstock for solar-driven processes due to the high gas production yields. Comparing the solar-driven experiments, gasification generates higher percentage of syngas (mix of CO and H 2 ) respect to total gas produced (sum of H 2 , CO, CO 2 and CH 4 ) than pyrolysis. Thus, solar-driven gasification generates better quality of syngas production than pyrolysis.Hydrogen Energy Publications LLC Three low-grade carbonaceous materials from biomass (Scenedesmus algae and wheat straw) and waste treatment (sewage sludge) have been selected as feedstock for solar-driven thermochemical processes.
