Published at Royal Society of Chemistry – Catalytic enhancement of production of solar thermochemical fuels: opportunities and limitations

Abstract: Solar thermochemical fuels are a promising low-carbon alternative to conventional fossil fuels, which must be swiftly phased out to mitigate the consequences of climate change. Thermochemical cycles powered by concentrating solar energy at high temperatures have demonstrated efficiency in the conversion of solar to chemical energy exceeding 5% and have been assayed in pilot …

Published at Energy Conversion and Management – Thermodynamic and economic analysis of a multi-energy complementary distributed CCHP system coupled with solar thermochemistry and active energy storage regulation process

Abstract: The combination of distributed energy systems (DES) and solar energy is considered a vital measure to save the usage of fossil energy. A new distributed combined cooling, heating and power (CCHP) system integrated with solar thermochemistry (STC) and energy storage (ES) units is proposed. The methane steam reforming (MSR) reaction is driven by solar …

Published at Next Energy – Direct solar-driven thermochemical CO2-to-fuel conversion with efficiency over 39 % employing hierarchical triply periodic minimal surfaces biomimetic foam reactors

Abstract: Solar-driven CO2 reforming of CH4 is considered a promising approach for achieving CO2 emission reduction and clean energy utilization simultaneously. However, reactors suffer from uneven temperature distribution and severe carbon deposition, leading to low solar-to-fuel efficiency. This study introduces a novel strategy for highly efficient solar-driven thermochemical CO2-to-fuel conversion based on hierarchical triply periodic …

Published at Crystals – Manufacturing and Thermal Shock Resistance of 3D-Printed Porous Black Zirconia for Concentrated Solar Applications

Abstract: A novel approach for manufacturing porous materials, foreseen as solar receivers for concentrated sun radiation, used in the power tower technology is presented. In such applications, materials are subjected to steep thermal gradients and thousands of cycles. Yet, materials consisting of honeycombs and ceramic foams showed insufficient thermal performance. By using the fused filament …

Published at Solar Energy – Techno-economic assessment of a numbering-up approach for a 100 MWe third generation sodium-salt CSP system

Abstract: This work presents the design and techno-economic analysis of a 100 MWe concentrated solar power (CSP) system using a supercritical CO2 power block with 700 °C input temperature. Aiming to leverage the relatively higher efficiency of small heliostat fields and potential multi-build discounts, a numbering-up approach is examined, developing four alternative configurations (1×100, 2×50, …

Published at Energy Conversion and Management – Selection of iron-based oxygen carriers for two-step solar thermochemical splitting of carbon dioxide

Abstract: The two-step solar thermochemical cycle is a prospective clean energy technology that enables the direct splitting of water and carbon dioxide for solar fuel production. However, immature oxygen carriers fundamentally restrict the solar-to-fuel conversion efficiency and thus prevent this technology from immediate industrial uptake. Focusing on the conventional iron-based oxygen carriers, this study intends …
