Excess heat from energy-intensive industries is often suitable for use in district heating systems but is usually unutilized. A detailed overview of the potentials available in the EU is now provided by a database of the sEEnergies project. In Germany, 29 petajoules of excess heat from industrial sites could be used, which corresponds to the demand of more than half a million households. The information is available as maps and downloadable datasets.
In a recently published Communication the European Commission proposes an EU heating and cooling strategy that aims to reduce the high share of fossil fuels which makes up about 75% of primary energy demand in the European heating and cooling sector.
Here renewable energy accounts for only 18% and
natural gas is the single major fuel with about 46%. The sector is extremely important: Heating
and cooling is responsible for 50% of the EU’s final energy demand. All in all,
this makes heating and cooling a major cause of the gas crises in 2006 and
2009. Reducing gas demand for heating and cooling can contribute substantially
to lowering the risk of future gas crises. These and similar figures that provide the
basis for the EU’s strategy document have been calculated in an ongoing project
by a consortium which involves the FORECAST team. The model FORECAST was used
for industry (Fraunhofer and IREES) and service sector (TEP Energy)
calculations while the residential energy demand was calculated using
INVERT/ee-lab (TU Vienna). Until this project has been finalized, we will
use both models to calculate scenarios for future energy demand for heating and
cooling and provide policy recommendations.
