Abstract: Hybrid concentrating solar power (CSP) plants with thermal energy storage (TES) and biomass backup enhance solar energy reliability and efficiency. TES provides energy during low sunlight or high demand, while biomass provides continuous heat generation when TES is depleted. Therefore, the current study developed three tree optimizers (fine, medium, and coarse) to predict the …
A new trigeneration study just published at Renewable Energy is a collaboration between Fatih Yilmaz from Isparta University of Applied Sciences in Turkiye, and Basharat Jamil from Spain’s IMDEA Energy Institute in Madrid. They have proposed a concept in which three power cycles would be deployed in sequence to supply electricity, heating, and freshwater generation …

Dear Colleagues, As the Conference Chair, it is my great pleasure to invite you to the 31st SolarPACES International Conference, which will be held in Almería, Spain, from September 23–26, 2025. Achieving full decarbonization of the energy sector, where two thirds of total demand is heat and one third is electricity, is a highly challenging …

Abstract Efficient utilization of full-spectrum solar photons is significant for improving the efficiency of solar energy conversion and thus alleviating energy shortage. In this work, a novel concentrated ordered conversion system based on a parabolic trough collector (PTC) that couples photocatalysis and Rankine cycle for hydrogen and electricity cogeneration to more efficiently use the full-spectrum …
Abstract Concentrated solar thermal (CST) systems, capable of driving high-temperature processes up to 2000 K, hold significant potential for chemical and industrial applications. This paper reviews methods for measuring concentrated solar flux, focusing on their role in calculating key optical performance metrics such as concentration ratio and optical efficiency. It also explores the challenges associated …
At each of the three towers at Ivanpah, heat from mirrors concentrating sunlight is focused up to a solar receiver. Water transfers the heat to a steam cycle power block at each base. PG&E has moved to cut short its 25 year contract with the Ivanpah tower solar project, which comprises three Concentrated Solar Power …
