The vast majority of power generation in the United States today is produced through the same processes as it was in the late-1800s: heat is applied to water to generate steam, which turns a turbine, which turns a generator, generating electrical power. Researchers today are developing solid-state power generation processes that are more befitting the 21st

Customer ServiceIn this study, a novel looped heat pipe battery (LHPB) was proposed to achieve the aforementioned function. By absorbing heat through the evaporator of the proposed LHPB, the working fluid was transformed into high-speed vapor and blasted the generator rotor sealed in the LHPB condenser, which directly converted waste heat into electricity.
The recovery of waste heat for power is a largely untapped type of combined heat and power (CHP), which is the use of a single fuel source to generate both thermal energy (i.e., heating or cooling) and electricity.
In the charging process, the mass flow rate of the waste heat increases from 296.02 kg/s to 352.93 kg/s because of the arrangement of the HP recuperator in the PR-PTES system and the R-PTES system. Then the amount of water stored in the heat storage system is boosted, and the COP of the HP cycle can be increased by 0.47.
By absorbing heat through the evaporator of the proposed LHPB, the working fluid was transformed into high-speed vapor and blasted the generator rotor sealed in the LHPB condenser, which directly converted waste heat into electricity. The proposed LHPB can realize excellent thermal management and effective waste heat recovery simultaneously.
Nevertheless, the low-grade waste heat, defined as the available energy contained in the liquid (< 90 °C), gas (< 200 °C), and solid (< 400 °C) , accounting for 66 % of the total waste heat loss and the recovery technologies are very limited caused by the wide distribution and the low quality .
Waste heat to power (WHP) is the process of capturing heat discarded by an existing thermal process and using that heat to generate power (see Figure 1).
