Socio-Techincal Aspects of Potential Future Use of Excess Heat from Kraft Pulp Mills
2009 (English)In: 22nd International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems: August 31 – September 3, 2009, Foz do Iguaçu, Paraná, Brazil, 2009Conference paper (Other academic)
The pulp and paper industry is one of the largest energy users in Sweden and in 2007 2.2 TWh of heat was delivered from pulp mills, mainly to district heating systems. In this study, two market kraft pulp mills and two energycompanies (ECOs) have been interviewed about their views on excess heat, energy efficiency and energy strategies.The interviews have been brought together with results from previous optimization studies concerning kraft pulp millexcess heat by the authors and results from other related work in a socio-technical synthesis that aims to provide amore comprehensive view on the factors that influence the utilization of kraft pulp mill excess heat than achieved inprevious studies. The results show that the kraft pulp mills are more positive towards sales of excess heat than theECOs, which can be related to the fact that the ECOs take a greater risk when entering a heat cooperation. Anotherbarrier to co-operations is the already existing utilities in the ECOs that compete with excess heat for the position asbase load in the district heating systems. Both internal and external use of excess heat can benefit from policymeasures. Other important factors are the view on energy-related investments in the mill, the level of communicationbetween the parties, and the goodwill qualities obtained through energy-efficient solutions.
