Increasing energy demand and shrinking fossil resources make it necessary to improve
the efficiency of existing power-consuming processes and to tap into energy
sources that have not been used widely until now. Low temperature heat sources
such as waste heat and geothermal energy in the range from 100 to 200 C are
widely available and their potential is largely untapped. In addition large amounts
of heat are rejected to the atmosphere every day by industry, wasting energy. The
rising cost of energy creates a need for society to be more efficient with energy,
and in-house power generation using this waste heat is an interesting option.
