“…They conclude that the wide variety of allocation methods makes comparison with other fuels extremely difficult. Rosen (2008) presents six allocation methods in detail and then argues that a common methodology would benefit cogeneration, as it would simplify evaluation of environmental impact. Beretta et al (2012) present four common allocation methods and argue that a new method is required, as the common ones do not take local conditions into account.…”

“…In that method, the different characteristics of heat and electricity are not accounted for. According to Rosen (2008), allocation should instead be based on exergy content; in other words, the energy quality should be taken into account. The exergy allocation principle reflects that electricity is more useful than heat.…”

“…There are also several previous studies of the consequences of applying different system boundaries (see for example Borrion et al,2012;Grönkvist et al, 2003 andWetterlund et al, 2010) and GHG emission allocation methods (see for example Beretta et al, 2012, Jungmeier et al, 1998and Rosen, 2008, with regard to heat as well as other energy carriers. In this paper we complement previous research by applying different methodologies to a DH system with CHP production and industrial excess heat, thus illuminating the difficulties that appear when assessing the two great potential heat sources in the EU.…”

Heat demand is a large contributor to greenhouse gas (GHG) emissions in the European Union (EU), as heat is largely produced using fossil fuel resources. Extended use of district heating (DH) could reduce climate impact, as DH systems can distribute heat produced in efficient combined heat and power (CHP) plants and industrial excess heat, thus utilising heat that would otherwise be wasted. The difficulty to estimate and compare GHG emissions from DH systems can however constitute an obstacle to an expanded implementation of DH. There are several methods for GHG emission assessments that may be used with varying assumptions and system boundaries. The aim of this paper is to illuminate how methodological choices affect the results of studies estimating GHG emissions from DH systems, and to suggest how awareness of this can be used to identify possibilities for GHG emission reductions. DH systems with CHP production and industrial excess heat are analysed and discussed in a systems approach. We apply different methods for allocating GHG emissions between products and combine them with different system boundaries. In addition, we discuss the impact of resource efficiency on GHG emissions, using the framework of industrial symbiosis (IS). We conclude that assessments of the climate impact of DH systems should take local conditions and requirements into account. In order for heat from CHP production and industrial excess heat to be comparable, heat should be considered a by-product regardless of its origin. That could also reveal opportunities for GHG emission reductions.

“…Holmberg et al [5] studied the allocation of fuel costs and CO 2 -emissions to heat and power in a CHP plant producing heat to an integrated pulp and paper mill and electricity, by using the energy, exergy and market based methods [6]. The results of this study indicated that depending on the emission factor and efficiency of alternative energy production form, the market based method or the exergy method allocate the lowest CO 2 -emissions to heat.…”

SUMMARYThe study deals with the energetic and exergetic analyses of a cogeneration (combined heat and power, CHP) system installed in a ceramic factory, located in Izmir, Turkey. This system has three gas turbines with a total capacity of 13 MW, six spray dryers and two heat exchangers. In the analysis, actual operational data over one-month period are utilized. The so-called CogeNNexT code is written in C11 and developed to analyze energetic and exergetic data from a database. This code is also used to analyze turbines, spray dryers and heat exchangers in this factory. Specifications of some parts of system components have been collected from the factory. Based on the 720 h data pattern (including 43 200 data), the mean energetic and exergetic efficiency values of the cogeneration system are found to be 82.3 and 34.7%, respectively.
