Electricity from waste heat
March 2013 – "Waste heat is one of the largest unused potential sources of energy in Germany", explains Frank Eckert, Managing Director of Dürr Cyplan. Nowadays, in the era of the energy turnaround in Germany, this is no longer acceptable. Primarily waste heat from industry, firing systems, and the use of geothermal heat sources are especially attractive application options for the ORC technology by Dürr Cyplan. Organic Rankine Cycle is a procedure that uses waste heat to produce electricity with the aid of an evaporation process.
The demand for ORC systems is increasing. Currently, the German Groß-Gerau Versorgungs-GmbH is investing in this technology. A biogas system of this municipal utility company has been converting biomass to biogas in order to fire two CHP units. The newly integrated ORC system has now been commissioned. It increases the efficiency of electricity generation and improves the heat utilization concept.
The total of the electricity generated has been increased from 8.3 to more than 8.7 million kilowatt-hours (kWh). Now, electricity can be supplied to 360 additional persons.
The energy-efficient technology by Dürr is suitable for a wide range of applications, since ORC can be coupled with the most diverse combustion engines and industrial waste-heat sources. More and more customers become aware of this potential: Last year, with marketing yet in its earliest stages, Dürr Cyplan already won five contracts for ORC systems.
