Published in the December Issue of Applied Thermal Engineering Abstract This paper reports on the development of a hierarchical control strategy for a multi-generation solar plant. The plant includes a linear Fresnel reflector, an organic Rankine cycle, an absorption chiller, a thermal storage tank, circulation pumps, and valves. The hierarchical control strategy consists of three …

Numerical modeling and simulation are necessary to design and optimize processes that include concentrating solar power (CSP) and industrial chemical processes; however, no co-simulation environment have been used or suggested in the literature for such plants. This paper suggests a promising approach to build a user-friendly simulation framework using open-source tools. DWSIM simulator was leveraged …

Published in the December 2022 issue of Energies Abstract It is difficult to measure the concentrated solar radiation flux (CSRF) inside a cavity receiver directly due to the complex geometry of cavity receivers. At present, most reports measure the CSRF at the aperture plane (generally coinciding with the focal plane of solar concentrators) of the …
To be published in the February 2023 issue of the Journal of Energy Storage Abstract High-temperature molten salt systems are employed in a wide variety of industrial applications, linked to energy production and storage, such as concentrated solar power, waste heat recovery, storage plants, fuel cells nuclear, etc. The reactivity of these salts is one …

Cspservices has entered into a license agreement for hydrogen mitigation technology that was developed by the renowned U.S. Department of Energy’s NREL: The system uses a palladium alloy membrane to separate and isolate hydrogen, which is then transferred via vacuum pumps into a catalytic oxidizer to be discharged as water vapor. A full-scale system was …

Layout of the solar field of mirrors to be installed near the current land application area to make nitrogen for fertilizer from biosolids – using solar thermal energy to dry the biosolids IMAGE@Ryan Shininger, Solar Dynamics In 2023, a wastewater treatment plant in New Mexico will begin making nitrogen for fertilizer from biosolids, using solar …
Working with member countries, SolarPACES—Solar Power and Chemical Energy Systems—has compiled data on concentrating solar power (CSP) projects around the world that have plants that are either operational, under construction, or under development. CSP technologies include parabolic trough, linear Fresnel reflector, power tower, and dish/engine systems. For individual concentrating solar power projects, you will …
