Decarbonizing District Heating in EU-27 + UK: How Much Excess Heat Is Available from Industrial Sites?

摘要: Energy-intensive industries across the EU-28 release unused heat into environment. This excess can be utilized for district heating systems. However, this is exception today, and potential contribution to decarbonization of not well quantified. An estimation heat, based on industrial processes, spatial matching areas necessary. We present a georeferenced database with annual production potentials at different temperature levels matched current possible areas. Our results show total 960 PJ/a (267 TWh/a) when exhaust gases are cooled down 25 °C, 47% 1.608 studied sites inside or within 10 km distance The calculated reveal that currently 230 (64 available areas, about 17% today’s demand buildings heating. In future, widespread low-temperature increase 258 (72 55 °C 679 (189 °C. substantially contribute decarbonize heating, however, major share will need supplied by renewables.
