Low-grade heat sources possess the potential to play a pivotal role in sustainable energy systems, revolutionizing our approach to energy generation and utilization. The field of low-grade thermal energy utilization has emerged as a promising frontier in energy research and technology development .
In recent years, there has been a growing urgency for deep decarbonization and energy security, as well as a change to global economic conditions, which have sparked an increased interest in the utilization of low-grade thermal energy.
Commentary on collected papers and future research outlook included. Approximately half of the global primary energy consumption is wasted in the form of low-grade (i.e., low-temperature) thermal energy, which has been traditionally overlooked and rejected to the environment, leading to low overall energy utiliization efficiencies.
Ultrathin MEMS thermoelectric generator with Bi2Te3/ (Pt, Au) multilayers and Sb2Te3 legs. Norbornadiene-based photoswitches with exceptional combination of solar spectrum match and long-term energy storage. Liquid norbornadiene photoswitches for solar energy storage.
Effective integration with existing infrastructure is crucial for practical implementation. Additionally, many low-grade heat sources exhibit variability in their availability, which can impact the reliability of power cycles.
There is an urgent need for alternative compact technologies that can derive and store energy from the sun, especially the large amount of solar heat that is not effectively used for power generation.
Our results demonstrate that such a molecular thermal power generation system has a high potential to store and transfer solar power into electricity and is thus potentially independent of geographical restrictions.
