Integrated energy systems analysis of industries and utilities: Potential for cooperationconcerning district cooling and industrial excess heat
(English)Manuscript (preprint) (Other academic)
Global warming and higher prices of fuel and electricity have increased the importance of energy efficiency measures in industry. Conversions of compression cooling to heat-driven cooling, and introduction of industrial excess heat in district heating systems, are two measures that can contribute to more sustainable energy systems. In the Södertälje energy systems, there is a potential for conversion of the cooling system due to the large industrial cooling loads. Heat-driven cooling processes such as absorption and adsorption cooling create a larger heat demand for combined heat and power (CHP), thus generating a larger production of electricity. Another option is to invest in free cooling, using lake water, and at the same time increase electricity production in the power plant through shifting to condensing mode. The increased use of fuel resources caused by the increased operation of the CHP plant can be reduced through introduction of industrial excess heat at peak loads to reduce the use of oil boilers and thereby further reduce the carbon dioxide emissions. The combination of reducing the electricity use from compression chillers, increased electricity production in the CHP plant, and increased use of industrial excess heat could thus reduce carbon dioxide emissions while at the same time reducing the system cost of the studied energy systems as a whole.
