[ad_1] In a video call from the US, SolarPACES caught up with Ranga Pitchumani, Editor-in-Chief of Solar Energy, a leading journal in the field. Dr. Pitchumani was the Chief Scientist at the U.S. Department of Energy (DOE), SunShot Initiative, Founding Director of its Concentrating Solar Power (CSP) program, and Director of the Initiative’s Systems (Grid) Integration […]

[ad_1] A new paper from researchers at PROMES-CNRS in France presents a control strategy to reliably deliver a precise thermal power from concentrated solar to meet industrial heat requirements. The objective was to design a proof-of-concept algorithm for operating a concentrated solar plant, but one intended primarily to deliver heat, and deliver it from thermal

[ad_1] Abstract: The reverse water gas shift (RWGS) reaction is a key pathway for CO2 utilization, particularly within Power-to-X process chains aimed at sustainable fuel and chemical production. Countercurrent chemical looping (CL-RWGS) using non-stoichiometric oxides can overcome equilibrium limitations of conventional RWGS reactors, enabling significantly higher CO2 conversions. However, modeling the limiting performance of such

They used operating data from Synhelion’s

[ad_1] Abstract:Improving the operating temperature of the solar receiver can enhance power cycle efficiency in solar power towers by raising the turbine-inlet temperature. However, maintaining high efficiency and safety at ultra-high temperatures (>1573 K) remains challenging. Therefore, this work focuses on the design and optimization of an oval tungsten solar receiver. Firstly, the receiver performance under

With a degree in aerospace engineering from the University of Stuttgart and a doctorate in energy technology from RWTH Aachen, she contributes extensive technical expertise. During her doctoral research

[ad_1] solar tower sCO2 cycle calcination Solar calcination + sCO2 cycle In a year-round California-based study, a Chilean research team has continued to advance a potentially more cost-effective and efficient form of Concentrated Solar Power (CSP) that leverages limestone’s heat generation during calcination. In this new solar tower form of CSP, the solar receiver in

[ad_1] 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

[ad_1] Abstract:Decarbonisation of the energy sector is critical for climate change mitigation, with the power sector remaining a major contributor to global emissions. Concentrating solar power (CSP) technology combined with thermal energy storage (TES) presents a promising solution to overcome this challenge. TES systems, particularly those utilising phase change materials (PCMs), offer efficient energy storage

[ad_1] Abstract: The use of renewable energy in the context of green hydrogen production requires suitable energy storage technologies to compensate for intermittent wind and solar resources. High-temperature electrolysis is a promising way to produce hydrogen as it has the highest electrical efficiency by using steam instead of liquid water compared to low temperature electrolysis.
