Saving the World, One Hot Well at a Time Leading Geothermal Expertise in Prominent Canadian Energy Developments
The subsurface scientists and engineers at RESPEC have supported geothermal development projects around the world. Our experts engage in geothermal exploration and development for geothermal power, as well as direct-use resource evaluation, due diligence, project management, exploration, geophysics, geochemistry, reservoir engineering, and drilling. As Canada has moved toward a renewable energy portfolio, geothermal power and heat have come to the forefront. RESPEC has become a leading geothermal expert and consultant in Canada by holding a prominent position on three of the six major geothermal development and research projects in the country. These historical projects are challenging on many levels, from science and engineering to
sociopolitical factors to regulatory and funding requirements. The Canadian government and private entities are investing millions of dollars to get geothermal power kicked off, and RESPEC has worked on projects with more than $70 million in combined grant funding.
We have sited a characterization well doublet and developed a well-testing plan. The reservoir models that will be needed for a bankable feasibility report, feasibility forecasting, and engineering design work are also being developed.
Clarke Lake
Qulliq Energy Corporation
British Columbia is seeking alternative energy solutions for electricity and heat, and geothermal resources will play a significant role in the province’s future renewable energy strategy. The depleted natural-gas reservoir Clarke Lake is being assessed by RESPEC as a potential site for the first geothermal power plant in British Columbia. The project is being developed under proponent the Fort Nelson First Nation, and RESPEC is teaming with Barkley Project Group Ltd. and Power Engineers.
A team headed by RESPEC performed the Phase I Nunavut geothermal feasibility study in 2018 for Qulliq Energy Corporation (QEC) as the first phase in identifying potential geothermal resources to offset the use of diesel for electricity and heat in isolated communities in the far northern territory of Nunavut. RESPEC was recently awarded Phase II and is managing all of the geothermal development for QEC. As a part of Phase II, RESPEC is leading a geothermal exploration program in the communities of Baker Lake, Resolute Bay, and Cambridge Bay that includes drilling an 800-meter-deep, temperature-gradient borehole in the Canadian Shield and designing a deep-drilling exploration program.

Hydrogen and Energy Storage for the Future Evolving With the Energy Industry and Its Demand
The global energy industry has undeniably experienced significant changes in the recent past and will continue to rapidly evolve based on a complex set of internal and external factors. Conventional energy sources will remain a critical component of our global energy mixture, but alternative energy sources will progressively contribute to the world’s growing energy needs. The increasing energy demand combined with an evolving energy-source portfolio puts significant pressure on industry to provide reliable and economical energy while addressing societal concerns. Energy storage has become crucial to alleviate this pressure and ensure a successful energy future. Energy storage has long been an important element of the energy industry; however, recent factors have renewed interest in the benefits provided by energy storage, such as: » Addressing the fluctuating market pressure and disruptions, as recently emphasized by the COVID-19 pandemic. » Providing functional flexibility for conventional energy sources to bridge the gap between operational limitations and changing energy demands. » Integrating variable renewable energy (VRE) (e.g., wind and solar) as a reliable energy source. » Incorporating hydrogen as an additional component of our global energy portfolio. VRE integration has been driving the need for new uses of energy storage to address challenges in bringing these technologies into

the fold. Because the energy produced by wind and solar sources cannot be easily controlled, VREs often produce excess energy when the wind is blowing and the sun is shining but fail to meet energy demands when the wind is calm and conditions are cloudy. To smooth out these fluctuations, energy storage can be used to capture energy when production exceeds demand and release that energy when production does not meet demands. Although several storage technologies exist, the need for long-term, bulk storage has shifted the focus toward compressed-air energy storage (CAES) and hydrogen storage in the subsurface. CAES involves using excess energy to compress and store air within specially engineered subsurface structures (e.g., salt caverns or mined excavations). When energy demand exceeds production, the compressed air can be withdrawn and converted back into electrical energy. Recent advancements in adiabatic technology have allowed CAES to be emissionsfree while efficiently providing hundreds of megawatts of energy for days.

Hydrogen produced from water electrolysis (i.e., green hydrogen) or hydrocarbon feedstock (i.e., blue hydrogen) can fundamentally be viewed in the same way as conventional energy sources (e.g., natural gas) where the hydrogen can be transported, stored, and converted into useful thermal or electrical energy. The critical advantage of hydrogen is that water is the only byproduct when hydrogen is converted into useful energy; therefore, hydrogen is developing into a technology that bridges the gap between our existing, conventional energy industry and the need to meet energy supply and demand imbalances while considering social pressures. At RESPEC, our storage solutions have typically focused on the subsurface bulk storage of liquid and gaseous hydrocarbons in salt caverns and mined caverns for the conventional energy industry; however, we have been evolving with the energy industry to build our experience with CAES and hydrogen storage in the subsurface. Although our experience with CAES dates to our pioneering U.S. Department of Energy research in the 1970s, we are continuing to expand our experience by providing engineering services for CAES projects across three continents and hydrogen storage projects in the United States and Canada. These services include initial geologic screening and project siting, exploratory drilling and coring, laboratory testing and analysis, and geomechanical and thermodynamic studies of storage design. In concert with hydrogen production and storage, we are involved with CO2 sequestration projects in the United States and Canada and are leading U.S. Department of Energy research into innovative CO2 sequestration technologies. The results and guidance provided by these services have led to several CAES and hydrogen storage projects that are advancing toward construction. As the energy industry continues to change and evolve, RESPEC’s engineers and scientists will be at the forefront to ensure that energy storage is positioned for the future.

making Eva Creek Wind Farm possible Accessing Remote Alaskan Wilderness to Help Harness Energy
In November 2012, Golden Valley Electric Association (GVEA) began generating power at a new, 24.6 megawatt (MW) wind farm near the small community of Ferry, Alaska, 15 miles north of Healy. This major accomplishment to address the energy needs of Interior Alaska was made possible in part by the RESPEC-designed road to Eva Creek. As of July 2011, access to this remote area of the Alaskan wilderness was via a single-lane mining road best traversed by an all-terrain vehicle (ATV), four-wheel-drive pickup truck, or helicopter. Just 2 months later, construction began to turn the rugged, 10-mile road into an access corridor capable of handling 380,000-pound loads; 150-foot-long wind-turbine blades; and all of the construction traffic to build 12 large wind-turbine generators. The 10 miles of access road and 6 miles of ridge-top road provided the necessary
access to the turbine sites and were designed to minimize ongoing maintenance (snow drifting) of the route and impacts to the surrounding fragile, alpine environment. As a design consultant to Michels (a leading wind energy contractor), RESPEC provided the civil design and land surveying services for the access roads; civil and structural design for the turbine foundations; and full engineering services (civil, structural, mechanical, and electrical) for the operations and maintenance and garage/warmstorage buildings.
For detailed information, please contact RESPEC’s Keith Hanneman, Transportation Lead Keith.Hanneman@respec.com
RESPEC designed the following elements of this project: » Improvements to the railroad-siding loading area at Ferry, Alaska » Upgrades to approximately 10 miles of Ferry Road/trail » Approximately 6 miles of new roadway from the end of existing roads to the turbine sites at Eva Creek Wind Farm » Foundations and gravel pads for the 12 wind turbines » Construction camp » Material sites and a concrete batch plant » Temporary laydown yards » Operations and maintenance building at Eva Creek » Garage/warm-storage building near the railroad siding at Ferry.

Providing the raw materials for alternative energy It Starts With Mining
RESPEC is a key provider of technical expertise to multiple companies working to supply the required raw materials for alternative energy. The future of alternative energy hinges on the development and mass production of reliable and economical energy storage solutions. The cost and power density of lithium-ion batteries, which typically use some combination of lithium, nickel, manganese, and cobalt, has reached the point that electric vehicles and variable renewable energy installations (VRE) (e.g., wind and solar) are attractive alternatives to fossil fuels. Adding cobalt to lithium-ion batteries improves both the power

density and life span of the battery. Most cobalt is currently sourced from the Democratic Republic of the Congo using mining methods that have raised numerous environmental and humanitarian concerns. To avoid these challenges and stabilize their supply lines, battery producers have begun seeking alternative cobalt sources with high social and environmental standards. One project that meets this need is the Iron Creek cobalt-copper project near Salmon, Idaho, owned by First Cobalt. RESPEC’s Mine Development Associates division recently completed an updated mineral resource estimate that shows the project could possibly contain over 24 million pounds of cobalt (12.3 million pounds Indicated and 12.7 million pounds Inferred), as well as considerable amounts of copper. That amount of cobalt is enough for millions of batteries for electric vehicles or VRE installations. Exploration that could expand the resource is ongoing at the Iron Creek property, including a geophysics survey announced in
October 2020 and additional drilling planned for 2021. First Cobalt also has a cobalt refinery in eastern Ontario that it plans to have operational as early as 2021, ensuring a 100% North American based cobalt source for battery manufacturers. Another element critical to the development of alternative energy is vanadium. While vanadium is best known as an additive to steel to improve its strength, another developing use for vanadium is redox flow batteries, which use vanadium in multiple oxidation states to store electricity. Vanadium batteries have several stability and safety advantages over lithium-ion batteries, which makes them ideal for stationary energy storage to support electrical grids or VRE installations. Victory Metals is currently developing a vanadium project called the Iron Point project near Winnemucca, Nevada, with technical advice from Mine Development Associates, a division of RESPEC, including exploration target recommendations and guidance on initiating a mineral resource estimation. The development of alternative energy sources will lead to a boom in the mining of numerous commodities at scales not currently supported by known resources. RESPEC has the technical ability and commitment to innovation to see new projects through from resource to production and will continue to be a leading contributor to the growth of alternative energy.

New Copper Mine in Arizona Achieves Production
Low-Cost and Environmentally Friendly Copper Extraction
Excelsior Mining Corp. announced on December 21, 2020, that its first copper cathode production has been achieved at the Gunnison Copper project in Arizona. This low-cost and environmentally friendly, in situ recovery (ISR) copper-extraction project is permitted to 125 million pounds per year of copper cathode production. The feasibility study projected an after-tax net present value of USD$807 million and an internal rate of return of 40 percent using a USD$2.75 per pound copper price and a 7.5 percent discount rate. The Gunnison Copper project is unique and cutting edge because of its ISR mining method. In this noninvasive method, boreholes or delivery wells are drilled into an orebody through which a dilute solution is pumped to dissolve the targeted minerals or metals. The solution moves through the rock in a controlled manner to nearby recovery wells, where the solution is pumped back to the surface for processing. Differential pumping rates or natural impermeable barriers are used to control the movement of the solution through the rock. Combined with wellfield design, this technique prevents solution from exiting the mine area. The pumping action of the recovery wells ensures that all of the pregnant solution is collected from the delivery well. In ISR mining of copper-oxide ores, the dissolving solution is usually weak sulfuric acid, which is the same acid used in open-pit and dump or heap-leach operations around the world. The boreholes or wells effectively become the mine access and the leach pad is left underground. Processing is generally done by chemical precipitation or solvent extraction/electrowinning
