Optimizing Geothermal Energy Production and Utilization Technology

Alberta possesses a vast low enthalpy geothermal resource (below 100 °C); however, it is currently not financially viable to convert this resource to electricity. 


Stirling engines are externally heated, closed-cycle heat engines capable of running at 0.5ºC temperature differences. With unconventional engine materials functional near 100ºC, Stirling engines present a financially sound solution to producing electricity from low enthalpy resources. 


The aim of this project is to develop engines for conversion of low grade heat into electricity. Candidate unit designs will first be manufactured at the bench scale, to gain experience and compare options. Successful unit designs will be mechanically coupled to form engines, and electrically coupled to form modular power stations.
