Heat demand in the German Industrial Sector The Combined heat and power (co-generation) Potential until 2030 and contribution to Flexibility

摘要

The development of the heat demand below 300°C and the development of available CHP technologies as well as the framework conditions all play a role in the future CHP potentials in industry. The changes in technologies are unexpectedly fast in parallel to the developments in wind and photovoltaics. In this way the perspective for operators of CHP plants, which can not be easily managed oriented only to the heat demand but as well as by the electricity prices in the markets. These prices have both chances and risks for CHP plants. The flexible operation of CHP plants is therefore a must also for industry changing their operation in the future as well and making CHP technologies more expensive per installed KW.These changes are a challenge for consultant engineers and CHP investors and operators. Finally they require a large technical knowledge as well as willingness for more complex configurations in order to make a contribution to the “Energiewende” or energy transition. Both the reduction of CHP-subsidies as well as the mere consideration of amortization times are fatal for the future potential investments. Changes in the political framework should be in line with the ambitious targets set.Historically the use of CHP technologies has been narrowly considered from the perspective of the insufficient use from existing heat sinks. In the long term this limitation on the heat side is complemented by the increasingly share of fluctuating electricity from renewable energy carriers. The technical flexibility of CHP plants perform a reasonale economic contribution also in the long term to the efficient supply of heat and electricity.
