High temperature heat pumps for space and process heating utilising geothermal energy.

Number: 0201

Author(s) : HEWITT N. J., TODD S.

Summary

Shallow and Deep Geothermal Heat has the capacity to make a significant contribution to the efficiency of space heating and process heating heat pumps. Geothermal Heat is a widely distributed resource, especially at lower temperatures not previously considered for energy applications. Initial borehole testing to deeper levels (about 2 km) have realised attractive temperatures of typically 50⁰C. However, modelling of the known strata in these parts of Northern Ireland reveals that the candidate layers on extraction of the heat from the aquifers will see a temperature drop to near 30⁰C. Nevertheless, the initial models reveal that this temperature can be maintained for 10 years in the first instance. Heat pump candidates are explored to make best use of this heat for a range of commercial and industrial space and process applications.
