Utilization of low-temperature heat sources for heat and power production

Low-temperature heat sources are available in many applications, ranging from waste heat from marine diesel engines, industries and refrigeration plants to biomass, geothermal and solar heat sources. There is a great potential for enhancing the utilization of these heat sources by novel thermodynamic cycle and cycle design, and use of multi-component working fluids.

These advancements will not only improve the performance of existing technologies, but also enable the utilization of low temperature heat sources, which are currently not utilized due to technical or economical infeasibility.Both power production and heat pumps may benefit from the development as both technologies utilize a heat source.

This makes it possible to cover the complete temperature range of low temperature sources. The development may contribute to significantly lower energy consumption in Danish industry and shipping. This will provide the scientific basis and devise potential innovations needed for implementation of technologies utilizing lowtemperature energy sources in Denmark.

Thereby, contributing to the development of the future society with no use of fossil fuels and with high shares of intermittent, renewable energy sources with electricity being the main energy carrier.
