Preliminary design and performance of a solar tower plant based on supercritical CO2 under the weather conditions of La Guajira, Colombia

Thermo-solar energy technology offers a promising potential for future sustainable power generation, especially those ones based en central tower receivers which can achieve higher temperatures for a higher thermal efficiency. Currently, these power plants still have obstacles and limitations which difficult its competition against fossil fuel based systems. For this reason, more efficient thermodynamic cycles are essential for the future of this installations, since this reduces the Levelized Cost of Electricity (LCOE) and facilitates the adoption of these new production methods. In the present work, a recompression cycle based on supercritical CO2 is adapted for its implementation in CSP plan with a central tower receiver exposed to the weather conditions in the Guajira region, in northern Colombia. The plant operation is evaluated according to the first law of thermodynamics and theoretical results obtained show the performance, thermal efficiency, annual energy produced and its availability during 3 years. For start, they indicate an improvement in the amount of energy per area produced and present the critical components which behaviour can be adapted for the production optimization
