Solar decomposition of fossil fuels as an option for sustainability

This paper presents an overview on solar-thermal decomposition of fossil fuels as a viable option for transition path from todayʹs permanent dependency on fossil fuels to tomorrowʹs solar fuels via solar thermochemical technology. The paper focuses on the thermochemical hydrogen generation technologies from concentrated solar energy and gives an assessment of the recent advancements in the hydrogen producing solar reactors. The advantages and obstacles of hydrogen generation via solar cracking and solar reforming are presented along with some discussions on the feasibility of industrial scaling of these technologies. Solar cracking and solar reforming processes are discussed as promising hybrid solar/fossil technologies to take considerable share during transition from fossil fuel dependency to clean energy based sustainability.
