In this article, power generation using solar and geothermal sources when simultaneously operated as CHP plants for waste heat recovery (WHR) is reviewed with the focus on the current state of the art applications for this waste heat.
Using renewable heat energy sources, recovering the waste heat, and enhancing the processes and energy efficiency can reduce the electricity dependency of several industrial applications. Renewable and waste heat have a low-grade enthalpic level and should be combined with other technologies to bring it to a practical level.
Generators can be driven using solar energy or waste heat . ERC have several advantages over other heat-driven refrigeration systems, including high reliability, simplicity, operation using low-grade waste heat, and low cost .
Very few studies exist in the literature that focused on the utilization of waste heat from CSP-based power plants. Waste heat was mainly recovered by utilizing the heat for desalination, combining other thermodynamic cycles for power generation, or water heating applications.
By combining any of the above techniques, more heat from a thermal source is recoverable for useful purposes. Using waste heat as a co-product of electrical generation results in higher efficiencies, reduction of cost and a reduction in greenhouse gas (GHG) emissions per kWh of energy produced.
3. Since some renewable energy sources such as solar are season-dependent, producing only cooling or heating as a product may not meet the local demands of a region. In such cases, waste heat is typically not used efficiently during some months of the year.
