Abstract: Carbon-neutral fuels are key to decarbonizing hard-to-abate sectors. Solar redox cycles can produce them by creating oxygen vacancies in a metal oxide capable of splitting water and CO2. The resulting synthesis gas can be processed into a liquid fuel like methanol. To close the carbon cycle, feedstock CO2 can be captured from the atmosphere …

Abstract: The Performances of direct absorption solar collectors (DASC) are limited by the stability of the nanofluid’s optical properties. This study investigates the performance and long-term stability of a graphene-based nanofluid under real on-sun operating conditions using an experimental parabolic trough pilot. The on-sun experiments were complemented with a detailed off-sun experimental evaluation of the …
