“…Abokersch et al, studied a DH network coupled with solar-assisted heat pumps, which led to an 80-83 % reduction of the environmental impact, with respect to the conventional technologies [55]. Maximov et al, assessed the use of a solar DH network with a seasonal thermal energy storage that provides space heating to the users in two locations in Chile [56]. Dynamic simulations were used to estimate the time-dependent thermal energy demand.…”

With the prevalent energy crisis and climate changes, decarbonising energy sector has become the need of the hour. An environmentally friendly way is the utilisation of solar energy which mainly involves the deployment of photovoltaic (PV) and/or solar thermal technology. Unlike electricity generation, the application of photovoltaics for the district heating & cooling (DHC) is relatively new. Also, this energy route is yet to be fully explored. This paper aims to provide an overview of the photovoltaic applications in the context of DHC sector. At first, the utilisation of solar energy in the DHC sector is briefly described and then the review of the available literature is carried out. It was understood that PV integration in the district heating and/or district cooling system can take place in different topologies such as PV technology, energy storage, and system configuration (centralized/distributed). On one side, this technology options support design flexibility based on local scenarios (i.e., climatic conditions, building types, energy cost). On the other side, selecting the best configuration remains a challenging task for design and planning engineers. The research database on the studied topic needs to be enhanced, with a focus on PV’s role in district cooling (DC). It is deduced that right technical and economic boundary conditions in the chosen region is important for the accelerated photovoltaic integration. Also, lower environmental impact throughout the whole life cycle of solar PV integrated DHC system is reported. PV assisted DC systems have the potential to revolutionize cooling sector, especially in the places where daytime electricity costs are high. Based on the SWOT analysis, it is concluded that there is an enormous opportunity for PV integration in the DHC sector with the upgradations in DH networks, developing DC networks and rising adoption of HPs. This overview is expected to be beneficial to researchers, policymakers and other stakeholders of district energy sector.

“…Raluy et al [28] applied the life cycle assessment method in estimating the environmental burden through the whole life cycle of the central solar heating plants with the seasonal storage system. Maximov et al [29] performed a multi-objective optimization of a solar heating system with seasonal thermal storage based on costs and greenhouse gas emissions as the objectives. Results show that STES improves the system performance by decreasing the emissions by 90% and only increasing the levelized cost of energy (LCOE) by less than 20% compared with a gas-heated system.…”

“…The shortterm storage TES has a charging and discharging cycle of hours to several days, which is called diurnal thermal energy storage. The long-term storage TES can store heat for several months and is called seasonal TES (Dahash et al, 2019;Renaldi and Friedrich, 2019;Maximov et al, 2021). The principle of seasonal TES is to store heat energy through heating equipment in summer, and then discharge it for space heating in winter (Kubiński and Szabłowski, 2020).…”

As the use of fossil fuels has led to global climate change due to global warming, most countries are aiming to reduce greenhouse gas emissions through the application of renewable energies. Due to the distributed and seasonal heating demand, the decarbonisation of heating is more challenging, especially for countries that are cold in winters. Electrically powered heat pumps are considered as an attractive solution for decarbonising heating sector. Since grid-powered heat pumps may significantly increase the power demand of the grid, this paper considers using local renewable energy to provide power for heat pumps, which is known as the grid independent renewable heating system including photovoltaic, wind turbine, battery storage system and thermal energy storage. This paper investigates a complete renewable heating system (RHS) framework and sizing the components to decarbonise building heating. The relationship between the reduction of gas consumption and the requirement of battery storage system (BSS) under the corresponding installation capacity of renewable components is analysed with their technical requirements. Then, according to different investment plans, this paper uses the particle swarm optimisation algorithm for optimal sizing of each component in the RHS to find a solution to minimise CO2 emissions. The results verify that the RHS with optimal sizing can minimise CO2 emissions and reduce the operational cost of natural gas. This work provides a feasible solution of how to invest the RHS to replace the existing heating system based on gas boilers and CHPs.
