DESIRED is a high-risk high-return project, focused on establishing the technological feasibility and sustainability of a novel fuel production system – the DESIRED system – for direct coprocessing of, possibly atmospheric, CO2   and water to produce multi-carbon (C2+) energy-rich products using sunlight as primary energy source. The DESIRED system will produce C2+ solar fuels (without overlooking C1 species such as methanol or methane) by direct coprocessing of CO2 and water using novel and recyclable hybrid photo-electrocatalysts, supported on frustules or zeolites, in an innovative photoreactor design applying, for the first time.
