Direct cycle supercritical carbon dioxide (CO2) in Concentrated Solar Power (CSP) plant with molten salt storage : a dynamic simulation using TRNSYS

Likewise, the world is trying to find clean and sustainable solutions that provide a constant flow of energy as well as combat greenhouse gases (GHGs). Pakistan too is facing this challenge and thus a model is developed and simulated to utilize the solar potential of Pakistan. This article addresses a very new and promising technology in CSP. Supercritical carbon dioxide (s-CO2) in a direct cycle can provide large amounts of power with little compressibility. This advantage along with its possible and imminent integration in the upcoming years with molten salt storage can also remove short term transients and provide stable power generation during the night. Finally, the effect of mass flow rate, pressure, and temperature is investigated in detail in a dynamic environment using TRNSYS with a a feasibility analysis for Pakistan.
