Abstract Particle heating receiver (PHR) based concentrating solar power (CSP) is widely recognized as the preferred path to reliable and cost-effective solar power. Use of solid particles rather than conventional fluids such as molten salts as collection and storage media, enables the operation of the PHR-based CSP plant at elevated temperatures (∼1000°C). This advantage leads to higher efficiency and lower levelized cost of energy (LCOE) produced by PHR-based CSP plants. However, designing and integrating the commercial solar power plant at high operating temperatures (∼1000°C), is a substantial challenge which has been overcome. Our research teams at King Saud University (KSU) and the Georgia Institute of Technology (GIT) have been working on the design and development of high temperature key sub-systems in PHR-based CSP plants. The proposed 1.3 MWe pre-commercial demonstration (PPCD) plant will incorporate the design evolved from our risk-reducing research activities performed at 300kW test facility at KSU and GIT. The DS-PHR of the PPCD will incorporate the KSU’s patented discrete-structured design in which the receiver will be enclosed in a cavity to minimize radiative and convective heat losses. Each PHR panel will have efficient particle flow control system for uniform particles outlet temperatures. Low-cost particulate materials with enhanced solar absorptance and resilience at high-temperatures have been identified to be used as heat collection and storage media. Inexpensive thermal energy storage (TES) bins will accommodate sand with temperatures ∼ 1000 °C. Multiple layered design of the TES bins will limit the heat loss to less than 1% per day (at scale). The current TES design allows easy access to the high-temperature bins for experimental observation and for future modifications. A patent pending skip hoist particle lift system design will be used for particle conveyance with expected mechanical efficiency of 75–85 %. Our lift design is simple, demonstrates autonomous operation with minimal mechanical complexity, minimized heat loss, and reduced maintenance. The heat exchanger proposed is a multi-pass shell-tubes design with high heat transfer coefficient. The design features discussed in this paper will lead to large scale commercial plants and similar small-scale designs for off-grid and remote applications at our anticipated service location which is in Saudi Arabia, and in Mideast and North Africa (MENA) region.

Potential Map

This study aims to build a potential map for the installation of a central receiver concentrated solar power plant in Chile under the terms of the average net present cost of electricity generation during its lifetime. This is also called the levelized cost of electricity, which is a function of electricity production, capital costs, operational costs and financial parameters. The electricity production, capital and operational costs were defined as a function of the location through the Chilean territory. Solar resources and atmospheric conditions for each site were determined. A 130 MWe concentrated solar power plant was modeled to estimate annual electricity production for each site. The capital and operational costs were identified as a function of location. The electricity supplied by the power plant was tested, quantifying the potential of the solar resources, as well as technical and economic variables. The results reveal areas with great potential for the development of large-scale central receiver concentrated solar power plants, therefore accomplishing a low levelized cost of energy. The best zone is located among the Arica and Parinacota region and the northern part of the Coquimbo region, which shows an average cost of 89 USD/MWh, with a minimum of 76 USD/MWh near Copiapó.
