Researchers at Ryerson University are collaborating with McClymont and Rak (MCR) geotechnical engineersto develop a new sustainable thermal storage technology that addresses the main challenges that have preventedgeoexchange adoption in a meaningful way in Ontario. An innovative thermal storage medium, based on aconstruction slurry will be developed and used as an underground thermal storage medium, coupled to a groundsource heat pump, to provide high-performance building heating and cooling. This new, inexpensivetechnology will be able to be effectively integrated with solar heating, making it more cost competitive withnatural gas, leading to increased adoption and considerable CO2 emissions reduction in the building sector.The newness of this proposed research is the inclusion of phase change material in bentonite l for use in theunderground storage medium. MCR geotechnical engineers will be building and testing a full-scale prototype.At the conclusion of this project, the team will have developed a new underground thermal storage and groundsource heat pump product and service offering that will be ready for full scale implementation.
