Effect of the use of industrial excess heat in district heating on greenhouse gas emissions: A systems perspective
2015 (English)In: Resources, Conservation and Recycling, ISSN 0921-3449, Vol. 100, 81-87 p.Article in journal (Refereed) Published
European policy promotes increased use of excess heat as a means to increase the efficiency of resourceuse. By studying possible effects on greenhouse gases, this article aims to analyze and discuss systemaspects of the use of industrial excess heat in district heating. Effects on greenhouse gas emissions arestudied by applying different energy market conditions with different system boundaries in time andspace. First, life cycle assessment is used to assess the introduction of excess heat in district heating in acontemporary system with different geographical system boundaries. Thereafter, future energy marketscenarios for Europe are investigated to explore possible future outcomes. This study concludes that boththe heat production system and the energy market conditions affect the system emission effects of usingexcess heat in district heating. Industrial excess heat in district heating can be beneficial even if it leadsto reduced local electricity production when unused biomass can be used to replace fossil fuels. It isrecommended that a strengthened EU policy should encourage the use of biomass where it has the mostfavorable effects from a systems perspective to ensure emission reductions when industrial excess heatis used in district heating.
