Projects

RGRL has identified reservoirs with fluids at suitable temperature and composition and with proven fluid deliverability that can be exploited at scale for geothermal energy AND these same fluids contain lithium and other metals present in economic concentrations.

RGRL currently has 143 sections (36,608 Ha) of geothermal rights and 261 sections (166,781 Ha) of Lithium mineral rights in the Hinton and Edson areas of Alberta.

RGRL also has interest in additional geothermal, lithium and CO2 sequestration leases of equal reservoir quality in western Canada. In essence the 165°C geothermal brines will be produced to generate electricity using an Organic Rankine Cycle (ORC) system and Lithium extracted from the brines before the brines are re-injected back into the formation of origin.

Green Lithium

Hinton & Edson areas of Alberta

  • RGRL’s geothermal brines have lithium and other valuable elements that can be exploited in tandem with generation of  geothermal energy
  • RGRL has secured a strategic number of Geothermal Leases from the Alberta Government with tested and known brine fluid temperatures exceeding 165°C with exceptional flow rates to support between 24 MW and 384 MW of uninterruptible emission free renewable energy.

Geothermal Emission Free, Base Load Electricity

Hinton & Edson areas of Alberta

  • Geothermal energy → the opportunity to produce base load power with zero greenhouse gas emissions
  • RGRL has identified reservoirs with brines of 165°C temperatures with proven fluid deliverability that can be produced and exploited at scale for significant quantities of geothermal energy
  • RGRL will develop multiple 24 MW geothermal facilities using proven ORC technology that can be scalable to greater than 384 MW of uninterruptible emission free renewable energy

Geothermal Energy From Hot Brines

Flow Rate Requirement

Input energy in geothermal power plants is defined as the product of the total mass of fluid and the average enthalpy.

Output Energy of Power Plant

Output energy determined from an estimate of the efficiency of the power plant.  The efficiencies for geothermal power plants are reported as a function of produced enthalpy, which is a function of temperature and fluid type.

Brine Requirements for Binary Power Plants

Turboden, using our data and using their 2 layer system (ORC) calculates 300 L/s to generate 24 MW gross.

Velika Ciglena ORC Geothermal:

Existing Geothermal Project Analogous to RGRL’s Project

Velika Ciglena project in Croatia began producing electricity in 2018 from a reservoir similar to RGRL’s geothermal reservoir in Alberta. Brine at 170°C is used to produce electricity to feed the local grid.

Turboden designed and manufactured a single 17.5 MW turbine for their project. Production and injection wells produce/inject a total of 222 L/s brine from a depth of 3000 m. Velika Ciglena geothermal field is a porous carbonate rock – not unlike RGRL’s reservoir.

In 1 year a 72 MW Geothermal Power Plant will displace 0.43 megatonnes of CO2 by not using a coal fired plant.
The produced brine from three geothermal units (72 MW) will be able to produce 20,000 tonnes of battery grade lithium per year.

Geothermal-Lithium Projects

Vulcan Energy Resources

have a large lithium resource in Germany (15.85 mt) LCE. Vulcan’s goal is to produce lithium hydroxide using geothermal energy, without using evaporation or fossil fuels. Vulcan has partnered with DuPont to access its DLE technology solutions.

Controlled Thermal Resources (CTR)

is developing the Hell’s Kitchen lithium and power project in Imperial Valley, California. CTR plans to produce 49.9 MW of geothermal power and lithium extraction of 20,000 tpa. CTR has joint ventured with Lilac Solutions using an ion exchange technology.
