“…Biogas combustion for co-generation has been considered in the past [25,[42][43][44][45], but availability, transportation and mechanical constraints have prevented it replacing natural gas CHP. Biogas is a strong solution to a critical problem for CHP, as it incorporates a renewable fuel source into co-generation and reduces waste [46,47]. Most CHP schemes will have a finance plan across 20-30 years, Energies 2019, 12, 310 6 of 21 meaning this "dirty" energy production is unlikely to shift without incentive.…”

District heating uptake has grown with the increasing need for cleaner and more efficient energy supply. This has resulted in a rising number of new developments signing up to a district heating scheme, typically powered by Combined Heat and Power (CHP) boilers or biomass boilers with supplemental electrical or gas grid connections. These schemes have advanced rapidly in recent years, with much of the research focus targeting lower carbon technologies, improved load prediction and peak demand management. We assess the current status of District Heating Networks (DHNs) in the United Kingdom using published case studies and suggest next steps to improvement. Our findings show that the United Kingdom has good potential for uptake of district energy given the current political climate and government incentives, however significant improvements must be made to further penetrate the heating market.

“…Heating comprises nearly half of the final energy consumption within the European Union (EU) and Austria [1]. Among various heating technologies, district heating (DH) grids stand out as an appealing choice for ensuring a consistent provision of space heating and domestic hot water (DHW) for buildings or industry.…”

District heating (DH) systems play a crucial role in meeting heating demands across the European Union (EU) and Austria, with significant potential for energy efficiency improvements and decarbonization. However, the transition towards climate neutrality by 2040 poses significant challenges, particularly in decarbonizing existing DH systems and integrating renewable energy sources. This work explores the application of absorption technologies, specifically absorption heat exchangers (AHX), absorption chillers (AC), and absorption heat pumps (AHP), in optimizing DH systems. The study investigates the utilization of AHX as transfer substations to increase heat capacity within existing grids by up to 30%, facilitating the integration of renewables and reducing distribution heat losses. Additionally, AC implementation for cooling supply demonstrates efficiency improvements through dynamic operation modes, renewable energy integration, and reduced electricity demand. Furthermore, AHP for waste heat utilization in DH power plants showcases environmental benefits, cost savings, and enhanced energy security. Through detailed techno-economic analyses and case studies, the paper evaluates the viability and economic feasibility of absorption technologies in DH applications. Challenges such as system integration, spatial requirements, and driving energy optimization are addressed, offering insights into overcoming barriers to adoption. Overall, the research highlights the transformative potential of absorption technologies in enhancing the efficiency, sustainability, and resilience of DH systems. By leveraging these technologies, DH operators and stakeholders can navigate the transition towards climate neutrality, while ensuring reliable and cost-effective heating and cooling solutions for urban areas.

“…The growing demand for cooling carries the problem of sourcing the necessary primary energy to drive the refrigeration cycles. Church [3] proposed a ranking scheme based on the assumption that the maximum effectiveness is obtained for low-grade input energy, as is the case of polluting agents or waste. According to this ranking, pollutants like solid waste, waste oil and sawmill residue are considered of the utmost priority, followed by waste heat from commercial and industrial environments, which scored second.…”

“…Here the water from the evaporator is reabsorbed into the liquid solution to reestablish the original salt concentration, while the generated absorption heat is discharged to facilitate the process. The resulting liquid solution is then pumped to the high-pressure side of the cycle (1-2), where it is preheated in the solution heat exchanger (2-3) and finally enters the heater (3)(4)(5)(6)(7), where the cycle is reiterated.…”
