“…According to the clean heating action plan, the building area heated by solar thermal will achieve 50 million m 2 in 2021 [8], accounting for 0.18% of the total heated area. Based on the research findings on the potential for solar thermal in future energy systems in EU countries [45], the overall solar thermal potential across EU countries is in the range of 3% ~12% of the total heat production [46]. Considering the vast heating demand and the cheap land resources in north-west areas in China, the solar heated area would achieve 756 million m 2 with an assumption of 3% of the total heat demand.…”

Solar thermal has contributed little for space heating in China. In 2014, although China shared 75.8% of the total solar collector installations in the world, only less than 0.3% of the solar collectors were used for space heating. To promote solar district heating (SDH) in China, based on Danish experiences and Chinese clean heating transformation practices, a PEST (policy, economics, social, and technology) analysis and a SWOT (strengths, weaknesses, opportunities, and threats) analysis on SDH development in China were conducted. An extensive survey and on-site investigation were carried out to identify the applicability of SDH in rural areas. SDH development strategies, roadmap, and decision-making process for a SDH project are summarized. SDH has a broad application prospect in China with abundant solar resources and favorable policies. The solar heated floor area can achieve 756 million m 2 with an assumption of 3% coverage of the total heat demand of buildings. Particular areas with low population density, scarce resources, and strict environmental requirements, e.g., Tibet, should be given a high priority for SDH. Rural villages and small towns with a better infrastructure, e.g., district heating networks, are the best target market for SDH in the next five years. With the development of seasonal heat storage technologies and the accumulation of practical experience, SDH can be expanded to industrial parks, large residential communities in sparsely populated northwest China. Integration of solar heat with existing heating networks in big cities with central heating will be challenging in the long run. Highlights Solar district heating has a broad application prospect in China. The solar heated area can achieve 756 million m 2 with an assumption of 3% coverage of the total heat demand of buildings.  High-performance flat plate collectors will significantly increase the reliability and reduce the operation & maintenance cost of solar district heating systems.  A solar assisted ground source heat pump system is a reliable solution as a form of solar district heating.

“…Further, Østergaard points out that EnergyPLAN fulfils the requirements for integrated energy modelling, such as for modelling relations of PV and battery systems in an energy system and that EnergyPLAN has been widely used in the academic field. It has been used at all scales from continental analyses [40], over national systems [41] to cities and islands [42], [43]. It is intended for the simulation of user-defines systems as opposed to endogenous investment optimisation [44].…”

Highlights-EnergyPLAN simulations of residential and communal batteries in combination with PV -Residential PV and battery set-up enables higher self-supply and customer involvement -Communal battery set-up leads to higher share of electricity fed to the grid -PV and batteries improve demand side management, balancing and production planning Abstract This paper presents an analysis of small consumers' involvement in smart island energy systems with a focus on the technical feasibility of photovoltaic (PV) systems in combination with batteries. Two approaches may be observed in the literature: the optimization on a household level with the aim of being self-reliant versus coordinated and collective technologies with increased integration across sectors and energy carriers. Thus, for household systems, the placement of a batterywhether aggregated or residentialcreates the basis for this investigation. The study is based on the case of the Danish island Samsø for which the two battery approaches are simulated using the energy system simulation model EnergyPLAN. Results indicate a tendency towards aggregated batteries being more favourable from a systems perspectivewhile on the other hand, residential batteries are more motivating and involving the consumers. The importance of minimizing flows to and from the grid as a result from fluctuating energy sources is addressed in both approaches. While residential batteries improve the individual household electricity supply, a communal battery would further regulate other inputs and demands. * Corresponding author [2]

“…In the International Energy Agency report "The role of Solar thermal in Future Energy Systems" [25], it is concluded that the energy system design is crucial when implementing solar thermal, that globally, the solar thermal potential is around 3e12% of the heat production and that it can be a valid alternative to scarce renewable sources such as biomass. It also shows how integrating large-scale solar thermal systems in DH networks has a better socioeconomic result than implementing individual rooftop solar collectors.…”
