Abstract
Even though the renewable technologies are getting a gradually increasing share of the energy industry, the momentum of its growth is far away from outweighing the dominance of fossil fuel. Due to the concern for ozone depletion, global warming, and many more environmental hazards caused by fossil fuels, it is essential to substitute the conventional energy sources with renewables. Since this replacement cannot be done overnight, the conventional energy technologies should be integrated with renewables to minimize the pace of adverse effects on fossil fuel–based industries in the meantime. This way, the industries can be more efficient by utilizing waste heat, which accounts for 50% of the total energy generated now. This review paper outlines the role of solar energy in the generation of power and cooling systems that are capable of utilizing low-temperature heat sources below 400 °C. The review is primarily concentrated on line-focused concentrated solar power (CSP)-assisted solar technologies to be integrated with organic Rankine cycle (ORC) and absorption cooling systems. Photovoltaic and similar multigeneration systems are also discussed in brief.
