Abstract

Biomass, including municipal solid waste, and solar energy are two of the inevitable sources for future decarbonized energy systems. Fresnel lens thermal collectors using cheap micro-structured foils is an interesting emerging medium-temperature solar thermal design that might be of high practical value, provided that its fluctuating output is managed. This study proposes a hybrid solar-waste solution using this type of collector for multi-generation via an Organic Rankine Cycle. The cycle is specially designed for supplying low-grade heat, power, and industrial heat (which is a very critical sector to be decarbonized) taking advantage of the generated stable solar-waste medium-temperature heat at zero emission level. To achieve this optimal design, the article conducts a thorough energy-exergy-economic-environment (4E) analysis of the system and employs the non-dominated sorting genetic algorithm (NSGA II) for the optimizations. A benchmarking analysis is also conducted to show the importance of industrial heat supply in this cycle. The results show that this hybridization, owing to the cheap and flexible heat delivery of the waste incinerator as well as the low cost of the solar collectors, is very effective for efficient and cheap multi-generation. Especially for industrial heat supply, the competitive levelized cost of energy (LCOE) of 23.96 €/MWh is obtained, which is way lower than today's achievable costs in the industry.
