“…This system met the designed solar fraction (50%) by covering 57% of the annual demand for 7000 m 2 floor area. However, the heat loss from this system was high due to a relative small storage volume [80].…”

a b s t r a c tApplication of seasonal thermal energy storage with heat pumps for heating and cooling buildings has received much consideration in recent decades, as it can help to cover gaps between energy availability and demand, e.g. from summer to winter. This has the potential to reduce the large proportion of energy consumed by buildings, especially in colder climate countries. The problem with seasonal storage, however, is heat loss. This can be reduced by low-temperature storage but a heat pump is then recommended to adjust temperatures as needed by buildings in use. The aim of this paper was to compare different seasonal thermal energy storage methods using a heat pump in terms of coefficient of performance (COP) of heat pump and solar fraction, and further, to investigate the relationship between those factors and the size of the system, i.e. collector area and storage volume based on past building projects including residences, offices and schools.

“…In Germany, 25 plants are currently in operation . Of these, many were installed in the period 1995–2005, stimulated by the 10‐year long governmental programme Solarthermie‐2000, launched in 1993 . Smaller markets in terms of installed collector area exist in Spain (16 plants), France (15), Greece (14), Poland (14), and Switzerland (9)…”

“…Heller reviewed 15 years of R&D for central solar heating in Denmark. Likewise, in Fisch and Küble, a review of solar‐assisted district heating plants in Germany is carried out, and in Lottner et al the project Solarthermie‐2000 is reviewed. Additionally in Lund and Lund et al, the penetration of solar district heating in Finland under different conditions is studied.…”

Summary Both district heating and solar collector systems have been known and implemented for many years. However, the combination of the two, with solar collectors supplying heat to the district heating network, is relatively new, and no comprehensive review of scientific publications on this topic could be found. Thus, this paper summarizes the literature available on solar district heating and presents the state of the art and real experiences in this field. Given the lack of a generally accepted convention on the classification of solar district heating systems, this paper distinguishes centralized and decentralized solar district heating as well as block heating. For the different technologies, the paper describes commonly adopted control strategies, system configurations, types of installation, and integration. Real‐world examples are also given to provide a more detailed insight into how solar thermal technology can be integrated with district heating. Solar thermal technology combined with thermally driven chillers to provide cooling for cooling networks is also included in this paper. In order for a technology to spread successfully, not only technical but also economic issues need to be tackled. Hence, the paper identifies and describes different types of ownership and financing schemes currently used in this field.

“…The third generation of DH systems, in 1970's, was using pressurized water of low temperatures (below 100°C) and instead of petrol oil various local fuels like coal, biomass or waste were used. Currently, RE sources such as solar and geothermal systems, are progressively incorporated into DH networks [9][10][11][12][13]. Nowadays, the trend is towards lower distribution temperatures of water between 30-70°C [14].…”

There is a considerable diversity of district heating (DH) technologies, components and interaction in EU countries. The trends and developments of DH are investigated in this paper. Research of four areas related to DH systems and their interaction with: fossil fuels, renewable energy (RE) sources, energy efficiency of the systems and the impact on the environment and the human health are described in the following content. The key conclusion obtained from this review is that the DH development requires more flexible energy systems with building automations, more significant contribution of RE sources, more dynamic prosumers' participation, and integration with mix fuel energy systems, as part of smart energy sustainable systems in smart cities. These are the main issues that Europe has to address in order to establish sustainable DH systems across its countries.
