“…District energy networks are already widely spread in Northern EU countries and China. An efficient district heating and/or cooling system has the potential to reduce the energy produced by fossil fuels with advantages both on environmental and economic aspects reducing both GHG emissions and costs of energy production [38,39]. The main advantage of district heating and cooling networks is the ability to combine different energy sources and systems including renewable energy sources, waste heat recovered by industrial plants, and cogeneration plants for the combined heat and power production (CHP) [40].…”

“…[12] describe District Energy (DE) technology and its potential for improvement. Efficiency can be improved by using energy saving equipment [13] and recovering industrial waste heat [14], and such measures usually reduce GHG and other emissions [13]. According to the U.S. Department of Energy [15], district heating can considerably reduce GHG emissions.…”

Background:District Energy (DE) is a technology capable of using renewable energy (e.g., solar thermal systems) and waste heat as energy sources efficiently. DE technology nonetheless has potential for improvement. Thermal Energy Storage (TES) can enhance DE performance significantly.Objective:An exergy analysis of a DE system which includes a solar thermal energy system and TES is performed, so as to improve understanding of its performance.Method:A case study based on the Friedrichshafen DE system in Germany is used to assess thermodynamically the role of solar energy and TES in a DE system. The system performance is separated into three modes: (1) fossil fuel is the only source of energy, (2) a discharging TES and fossil fuel provide heat for the DE system, and (3) solar energy and fossil fuels are the energy supplies. Exergy analyses are conducted for each performance mode and the overall DE system.Results:The results quantify the benefits of incorporating solar energy and TES on the performance of the Friedrichshafen DE system, and demonstrate that the overall exergy efficiency of the DE system increases from 23% to 27% with assistance of solar thermal collectors and TES, while the total energy efficiency increases from 83% to 87%.Conclusion:An increase of exergy efficiency is observed when TES is added to a DE system, due to a reduction in solar thermal energy loss by the TES, which allows more solar energy to be converted to useful energy to satisfy the DE system thermal energy demand.

“…Nevertheless, most is low-temperature grade heat, explaining why its most common use is warming of fluids for heating or other purposes [2][3][4]. Thermoelectric generation is a promising technology for recovering low-temperature grade heat [5,6], it presents attractive characteristics such as no moving parts, modularity, reliability, robustness and maintenance free [7].…”

Waste heat generation has a widespread presence into daily applications, however, due to the low-temperature grade which presents, its exploitation with the most common technologies is complicated. Thermoelectricity presents the possibility of harvesting any temperature grade heat; besides it also includes many other advantages which make thermoelectric generators perfect for generating electric power from waste heat. A prototype divided into two levels along the chimney which uses the waste heat of a combustion has been built. The experimentation has been used to determine the parameters that influence the generation and to validate a generic computational model able to predict the thermoelectric generation of any application, but specially applications where waste heat is harvested. The temperature and mass flow of the flue gases and the load resistance determine the generation, and consequently, these parameters have been included into the model, among many others. This computational model incorporates all the elements included into the generators (heat exchangers, ceramics, unions) and all the thermoelectric phenomena and
