Abstract

Ubiquitous low-grade heat energy is usually wasted without use, which could be valuable for converting it into electricity. Energy conversion from primary energy carriers to the final energy of use is subject to considerable losses equivalent to about 70% of the global primary energy consumption. The major loss is identified as waste heat and 63% of them are regarded as low-grade heat below 100°C. Moreover, all of the waste heat in food processing, and commercial and building sectors almost belongs to the low-grade waste heat. How to effectively and economically recover the low-grade heat is critical to improve the overall energy efficiency and alleviate heat island effects for a sustainable future. Conversion is however still a great challenge because converting low-grade heat to electricity is inefficient due to the low-temperature differential and the distributed nature of the heat sources.
