Abstract Heliostat fields represent the primary energy input for concentrating solar-thermal power based on power tower technology. They typically account for 40 %–50 % of the implementation cost of a power tower plant. Therefore, it is essential to optimize the solar...
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...
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 concentrated solar firm Vast for next-generation sodium-based concentrating solar power...

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...
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...
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...
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,...
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...
Abstract Concentrating solar power plants are a clean energy source capable of competitive electricity generation even during night time, as well as the production of carbon-neutral fuels, offering a complementary role alongside photovoltaic plants. In these power...
Abstract Solar thermochemical hydrogen production using redox-active metal oxides is a promising pathway for the production of green hydrogen and synthetic fuel precursors. Herein, the perovskite material (La0.6Sr0.4)0.95Mn0.8Ga0.2O3−δ (LSMG6482) is identified as a...
NREL's Sand-based 100-hour long-duration thermal energy storage technology moves to demonstration phase at 10 hours Four years ago, researchers at the National Renewable Energy Laboratory (NREL) won Department of Energy (DOE) ARPA-E funding to invent a new...
We are pleased to share that this year the "𝗢𝘂𝘁𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴 𝗣𝗮𝗽𝗲𝗿 𝗔𝘄𝗮𝗿𝗱" from the ASME (The American Society of Mechanical Engineers) goes to a team at our institute! This was announced during the 18th International hashtag#Conference on Energy Sustainability in Anaheim,...
Abstract Hydrogen holds promise as a clean energy carrier, but its industrial utilization is currently constrained by the challenges of green production and efficient cross-regional delivery. To this end, a novel integrated hydrogen energy system considering the...
Abstract The van’t Hoff method is a standard approach for determining reaction enthalpies and entropies, e.g., in the thermochemical reduction of oxides, which is an important process for solar thermochemical fuels and numerous other applications. However, by...
Abstract Ammonia synthesis via the catalytic Haber–Bosch process is characterized by its high pressures and low single-pass conversions, as well as by the energy-intensive production of the precursors H2 and N2 and their concomitant greenhouse gas emissions....
Climate policy in the US Inflation Reduction Act (IRA) provides powerful incentives to generate renewable energy and phase out fossil fuel production. One way is to repurpose old fossil fuel infrastructure as clean energy. Laws already require that oil and gas...
[Ed: Addendum: As of March 2025, the Redstone project is completing the commissioning stage with commercial inauguration expected soon.] The California start-up SolarReserve had initially developed the project in 2014, competing during the early years of South...
Successful Projects Will help lower cost of CSP and support the next generation of highly trained solar field workers Heliostats, the large mirrors that track the sun to reflect and direct its rays to heat a solar receiver— are critical for efficient, cost-effective...
