Feasibility analysis of CSP Technology coupled with TES system for power generation in industrial plants of Bangladesh

Abstract

Different technologies and approaches to diverse methodology may be used to convert solar energy into electrical power, making it an important renewable energy source across the world. Photovoltaic (PV) conversion and Concentrating Solar Power (CSP) are two separate technologies for converting solar energy into electricity. In the realm of solar energy harvesting, Concentrating Solar Power (CSP) is seen as a key future option. It is more efficient and lasts longer than PV cells. CSP plants with integrated thermal energy storage (TES) technology can provide up to 12 hours of power reserve under optimal circumstances. We sought to find the optimum place in Bangladesh for a feasibility study based on the place's high average temperature and the amount of flat land that was available. Following our comparisons, we believe Kushtia may be the location we've been seeking. As part of this project, we built and optimized a 10 MW Power Tower Molten Salt-based stand-alone CSP power plant with 12 hours of thermal storage for Kushtia in System Advisory Model (SAM). It was decided that the stated site should have a DNI design point value of 950 W/m2. With a power cycle efficiency of 40.58 percent, the optimized plant's gross power cycle output is determined. There are two key obstacles for developing any CSP-based power plant: cost and the overall area it covers. The break-even threshold for this specific plant against conventional unit cost has been calculated in this study using extensive numerical analysis. The proposed power station is compared to a standard 10 MW steam power plant to evaluate its environmental and economic benefits and drawbacks. Future CSP researchers will benefit from this paper's thorough overview of the technology and research in this area. Additionally, Bangladesh's solar thermal power plant development and innovation is encouraged by this plant's feasibility study.
