“…The above UK surplus heat database was also recently used in combination with information on the magnitude, temperature and location of the heat that is rejected by industrial sites in order to determine the potential for supplying district heating networks (DHNs) by Cooper et al [24]. This assessment was based on a number of relevant criteria: the maximum allowable distance between the heat sources and demands, the minimum heat density of the demands which were considered feasible, the heat losses that might occur, and the seasonal profile of the heat demands.…”

“…High and low estimates of the heat rejected by the industrial sites were compared. Domestic and non-domestic heat demands were also examined, and the latter was found to have marginally greater potential [24]. Only half of the heat which is rejected by industry could be utilised by DHNs, when the most appropriate distance and heat demand density criteria were employed.…”

“…• It seems probable that non-domestic demands will form the majority of the heat demands which are initially met by industrial surplus heat supplied via DHNs [24]. They are likely to present initially more feasible space heating opportunities that make good use of heat rejected by industrial sites.…”

“…However, domestic heat demands are greater overall, and so as district heating develops in the UK, they will represent the bulk of the heating requirements that might ultimately need to be supplied. But should the DHNs primarily be required to satisfy seasonally variable space heating loads, then industrial waste heat would need to be supplemented with other, more flexible, heat sources [24]. Obviously, the waste heat which is rejected by industry has many possible uses.…”

“…The method proposed here uses a systematic and easy approach (neither strong mathematical skills nor non-widely used software is required) and manages to propose an energy strategy for such a big region as EU-28 based mostly on available public data (with the exception of the plant data obtained through the GESTIS database by using the ArcGIS software). This is of great importance as other methods are network-oriented (district heating network); lack from massive surface applicability [6], being inadequate for such a big area as Europe; are limited to industrial sites [7]; or present assessments which need a district heating network taxonomy [8], information not available in the vast majority of the cases. As a consequence, they are not useful for the purposes of this paper.…”

Yearly, EU-28 conventional thermal generating plants reject a greater amount of energy than what ultimately is utilised by residential and commercial loads for heating and hot water. If this waste heat were to be used through district heating networks, given a previous energy valorisation, there would be a noticeable decrease in imported fossil fuels for heating. As a consequence, benefits in the form of an energy efficiency increase, an energy security improvement, and a minimisation of emitted greenhouse gases would occur. Given that it is not expected for heat demand to decrease significantly in the medium term, district heating networks show the greatest potential for the development of cogeneration. However, to make this happen, some barriers that are far from being technological but are mostly institutional and financial need to be removed. The purpose of this review is to provide information on the potential of using waste heat from conventional thermal power plants (subsequently converted into cogeneration plants) in district heating networks located in the EU-28. For this, a preliminary assessment is conducted in order to show an estimate of the cost of adopting an energy strategy in which district heating networks are a major player of the energy mix. From this assessment, it is possible to see that even though the energy strategy proposed in this paper, which is based on a dramatic increase in the joint use of district heating networks and cogeneration, is capital-intensive and would require an annual investment of roughly 300 billion euros, its adoption would result in a reduction of yearly fuel expenses in the order of 100 billion euros and a shortening of about 15% of the total final energy consumption, which makes it of paramount interest as an enabler of the legal basis of the "Secure, Clean and Efficient Energy" future enacted by the EU-28 Horizon 2020.

A review of modelling and optimisation techniques for district heating systems

Summary This article provides an extensive survey on the modelling and optimisation of district heating systems (DHSs) focused on the heat distribution network. For this purpose, the major components of a DHS have been described and discussed, and their modelling has been briefly reviewed, including numerical simulation models for heat sources, end‐users, and especially the distribution network. The main deterministic and heuristic optimisation techniques are briefly described. Additionally, a single‐objective and multiobjective optimisation problem is generally formulated, and the main optimisation criteria for the design and operation of the distribution network are synthesised and analysed. The state of the art in DHS optimisation has been also reviewed and categorised. Finally, some recommendations for future developments were included.
