SYSTEMS ANALYSIS AND CO2 REDUCTIONS USING INDUSTRIAL EXCESS HEAT
2013 (English)Conference paper, Presentation (Other academic)
The adopted Energy Efficiency Directive stresses the importance of using excess heat as a way to reach the EU target of primary energy consumption. Utilization of industrial excess heat may result in decreased energy demand, CO2 emissions reduction, and economic gains. In this study, an energy systems analysis is performed with the aim of investigating how excess heat should be used, and the impact of global CO2 emissions. The manner in which the heat is recovered will affect the system. The influence of excess heat recovery and the trade-off between heat recovery for heating or cooling applications and electricity production has been investigated using the energy systems modeling tool reMIND. The model has been optimized with regard to system cost. The results show that it is favorable to recover the available excess heat in all the investigated energy market scenarios, and that electricity production is not a part of the optimal solution. The trade-off between utilization of excess heat in the heating or cooling system depends on the energy market prices and the type of heat production. The introduction of excess heat also reduces the CO2 emissions in the system for all the studied energy market scenarios.
