Geothermal Energy: Solutions for a Zero-Emissions Sustainable Energy Future
Presented by Lauren Boyd, Geothermal Technologies Office, US Department of Energy
Rocks of intermediate depth (100-1000 m) and those in the deep (greater than 1 km) subsurface represent an environmental resource to aid the energy transition and to achieve improved environmental outcomes. Porous and permeable sediments can be used to store fluid and solid wastes through processes of injection. Suitable porosity and permeability are needed for fluids disposal (CO2, waste water, acid gas), and slurried solids may be disposed in sediments through fracture injection, a process that has been taking place in the oil industry for over 40 years. Particular emphasise is placed on the potential for sedimentary rocks to accommodate injection and to dissipate pressures, but caution is warranted: the huge volumes of CO2 proposed for injection will exceed the sediments’ capacities in many areas, leading to regional pressurization and increased escape risks.
Part 2 of the Geothermal Series from the CSEG Emerging Professionals Program. Guest speaker Katie Huang, G.I.T. The topic is the summary and geological overview of the Alberta No. 1 project, and how we assessed the temperature of target formations.
Part 1 of the Geothermal Series from the CSEG Emerging Professionals Program. Guest speaker Dr. Catherine Hickson, P.Geo. The Alberta No. 1 project in the context of renewables in Alberta's energy mix, why we are pursuing geothermal, and what hurdles the project is facing.

Geothermal gradient in NWT = 20°C - 60°C per kilometer of depth. At 5 km, temperature could be between 100°C and 300°C.

The Four Geothermal Pillars
1. High-grade geothermal where steam is generated to drive turbines: ~T>140°C
2. Warm fluids in porous and permeable strata: ~T = 70-140°C
3. EGS – Enhanced Geothermal Systems, warm, low permeability: ~T = 70-140°C
4. Shallow, heat-pump based geoexchange, storage of heat in the upper ~500 m Below ~70°C – “district heating” or direct use of heat for drying, greenhouses, etc.

Deep geothermal needs a high enough T for co-generation – power + heat. And we need to drill at least 3-4 km deep to get 60-70°C. Shallow geothermal (GSHP) becomes inefficient because the ground cools more and more each year. But if the shallow ground T is OK and is maintained annually – heat pumps have a COP of 3 to 4!! Good use of power.

Direct Utilization of Geothermal Energy From Coast to Coast: a Review of Current Applications and Research in Canada (2015)
An invited lecture given to the McGill Energy Association in Montreal, Canada on Nov 6, 2014. The lecture covers: geothermal electricity production, direct-use applications and a discussion of career opportunities in the geothermal industry. Ryan Libbey is a founder of the Canadian Geothermal Research Council (CanGRC) and a Lead Geologist for Adage Geothermal Inc.
