Abstract: Wind loads are a major driver of heliostat cost. Standardized methods and tools are needed for a more detailed understanding of the static and dynamic loads of a heliostat design. This will enable cost reduction of wind-dependent heliostats to avoid unnecessarily conservative heliostat designs and increase field efficiency and reliability to reduce the risk …
High-temperature liquid sodium receivers able to run at over 700°C may allow use of modular multi-tower system configurations similar to that being developed by the Australian firm Vast Solar (now Vast) for next-generation sodium-based concentrating solar power (CSP). Unlike today’s one tall central tower encircled by one large heliostat field, a liquid sodium-based CSP system …
Mars Petcare will use this kind of parabolic trough concentrated solar thermal (CST) collectors for direct solar industrial heat and a thermal energy storage system also heated by electricity from Victoria’s solar-rich grid Mars petcare factory to tap sunlight for CST heat plus leverage Victoria’s world-leading renewable grid to electrically heat thermal energy storage. …

Abstract: Two-step thermochemical fuel production cycles powered using concentrating solar systems offer a route to convert solar energy to chemical fuels. In this work, we offer a critical assessment of the state of the art, a detailed technical analysis of this technology in terms of theoretical limitations and potential performance, and potential paths forward in …
Abstract: The reformation of methane to hydrogen and steam in a falling particle solar reactor (FPSR) is a promising method to use the solar energy, which converts solar energy into chemical energy. FPSR has higher operation temperature, higher pressure bearing capacity and more direct heat energy storage than those of traditional reactor. However, due to …
Abstract: The reactor is the core component of the hydrogen production system. Although hydrogen production using solar energy as the heat source can effectively reduce carbon emissions, the reactor faces the problem of uneven heating caused by the collector, and the uneven temperature distribution will significantly affect the hydrogen production process. A key characteristic of …
Manuel Romero and Aldo Steinfeld receive the SolarPACES Lifetime Achievement Award from Robert Pitz-Paal On the closing day of the SolarPACES 2024 conference in Rome, Aldo Steinfeld and Manuel Romero were jointly awarded the Lifetime Achievement Award, in recognition of their over 20 years collaboration in pioneering and developing the use of concentrated solar thermal …
Heat from solar for a hydrogen production system working like a conveyor belt MIT’s Heat-based solar hydrogen from a train of solar reactors boasts 70% heat recovery and heat-to-hydrogen from 10% to 40% In solar reactors that use solar-heated thermo-chemistry to produce hydrogen from water, heat recovery is needed to increase efficiency and, thus, lower …

Abstract Direct air capture (DAC) of CO2 has gained attention as a sustainable carbon source. One of the most promising technologies currently available is liquid solvent DAC (L-DAC), but the significant fraction of fossil CO2 in the output stream hinders its utilization in carbon-neutral fuels and chemicals. Fossil CO2 is generated and captured during the …
