WebAbstract. Given the future importance of solid carbonaceous feedstocks such as coal, coke, biomass, bitumen, and carbon-containing wastes for the power and chemical industries, gasification technologies for their thermochemical conversion into fluid fuels are developing rapidly. Solar-driven gasification, in which concentrated solar radiation is supplied as the … WebCharcoal, wood and paper have ben gasified in a packed-bed reactor using steam and solar energy. The steam was generated by spraying water directly on to the surface of the fuel and, at the same time, heating the fuel at the focus of a solar furnace. Half of the steam reacted with carbon and 30 pct of the incident solar energy was stored as chemical …

WebSolar thermal cracking, reforming, and gasification integrate carbonaceous fuel to produce synthesis gas and hydrogen and therefore are not emission-free. The concentrated solar power technologies require further development and cost reductions before they can be scaled up to have a meaningful impact on renewable energy targets towards 2050.
WebUncertainty in the price of conventional energy sources, such as oil and natural gas, along with increasing evidence of climate change have rekindled great interest in the development of processes that can produce clean synthetic gasses (hydrogen and carbon monoxide).
