Cornell University — Ithaca, NY
Developing ESG in conjunction with a district heating system is a part in Cornell University's Climate Action Plan for their Ithaca campus. The project began in 2018 with the preparatory phase to determine feasibility, gain funding and monitor baseline seismicity. The project reviewed $7.2 million in funding from the USDOE. The test well will be drilled in spring of 2021 at a depth of 2.5-5 km targeting rock with a temperature >85°C. The site is planned to supply 20% of the campus' annual heating load. Promising reservoirs have been proposed in the Trenton-Black River formation (2.2 km) or in basement crystalline rock (3.5km).

Since 2007 the university has committed to achieve net carbon neutrality by 2035 from the baseline 2008 emissions. Acting as the first Ivy league institution to take on such a sustainability goal. Cornell's Ithaca campus as of 2020 is powered by 6 solar farms, providing a total of 9.85 megawatts of power. In counterpart to Lake Source Cooling, heating needs plan to be met through the development of Earth Source Heating, a mid to low-grade enhanced geothermal system. The geothermal system is planed to supply 20% of campus heating demand. The Earth Source Heating project has received a $7.2 million grant from the DOE, and researchers plan to drill a test well in Spring of 2021 on Cornell land. The wells for Earth Source Heating will be 3-5 km deep reaching temperatures of >150°C. Waste biomass burning will be used to cover the estimates 20 'cold days' when the geothermal can not provide peak heating.
