Published at Industrial & Engineering Chemistry Research – Solar Thermochemical Production of Syngas from H2O and CO2─Experimental Parametric Study, Control, and Automation

Abstract: We report on an experimental parametric study performed on a modular and fully automated solar fuel system for the solar-driven thermochemical splitting of CO2 and H2O. Concentrated solar energy is used as the source of high-temperature process heat for effecting a ceria-based redox cycle, producing syngas with a tailored H2/CO ratio. We determine the influence …

CSP technologies …

Published at Applied Energy – A review of solar thermochemical cycles for fuel production

Abstract: Solar-driven CO2/H2O splitting via a two-step solar thermochemical cycle is a promising approach for fuel production and carbon neutrality to address the intermittent instability and low energy density of solar energy while taking advantage of its clean and nonpolluting nature. However, current experimental efficiencies are still below theoretical levels due to various limitations such …

Published at Joule – Ultra-long-duration energy storage anywhere: Methanol with carbon cycling

Abstract: Wind and solar generation are rapidly expanding around the globe as their costs come down and societal pressure to reduce greenhouse gas emissions rises. To supply a high fraction of electricity demand with variable sources, different types of storage are needed to balance daily, weekly, seasonal, and interannual weather fluctuations. Battery storage can bridge …

Published at Journal of Cleaner Production – Sustainable assessment of an integrated energy system coupled with solar thermochemical cycle

Abstract The energy transition globally makes the development of carbon-free and low-carbon fuels obligatory as these fuels cannot only be utilized as energy carriers but also for long-term energy storage. This paper presents the energy, technoeconomic, and environmental assessment of a new hybrid renewable energy integrated system with a novel concept of the thermochemical cycle …
