A Review on Full Life Cycle Research of Organic Rankine Cycle Technology
Organic Rankine cycle(ORC)technology can be used for low-grade thermal power generation,and has broad application prospects in renewable energy development and waste heat recovery.With the"double carbon"goal proposed,low-carbon energy and power system has become an inevitable trend.Therefore,the environmental performance index of ORC technology is more and more important.This paper summarizes the research status of the environmental protection performance of the ORC technology in the whole life cycle,summarizes the analysis process of the life cycle assessment(LCA)of the ORC technology,classifies the relevant research according to the type of heat source,summarizes its environmental impact characteristics,evaluates the environmental protection performance of common working fluids,and finally discusses the development trend of the life cycle research of the ORC technology.The study found that the existing inventory data in life cycle assessment is mostly secondary data,and the Recipe method is the most commonly applied evaluation method.The equipment production and substance leakage in the ORC system are important factors affecting its environmental performance.
