Mijnwater starts drilling for new heat source on Terhoevenderweg in Heerlen New source expands Parkstad’s district heating and cooling network Mijnwater has started drilling work for a new heat source at Terhoevenderweg in Heerlen, marking another important step in the expansion of its sustainable heating and cooling network in Parkstad. After a period of preparation, work began this week and is expected to continue for three to four weeks. Because the operation must be completed safely and efficiently, the drilling is taking place 24 hours a day, seven days a week. The project is part of Mijnwater’s broader effort to strengthen a low-carbon energy system for the region. The new source will tap warm groundwater in a former mine passage deep underground and feed that energy into the company’s network. For Heerlen and the surrounding area, this means further development of a district energy system that draws value from the region’s mining past while supporting a more sustainable energy ...
The Heat Beneath Our Feet: How Canada’s First National Geothermal Roadmap Could Redefine Clean Energy
The Heat Beneath Our Feet: Canada Invests in First National Geothermal Energy Roadmap
By: Robert Buluma
With a conditional investment of $468,000 through Natural Resources Canada’s Energy Innovation Program, the government is backing the Canadian Deep Geothermal Roadmap project. Led by the Canadian Deep Geothermal Coalition and supported by the Cascade Institute as the secretariat, this initiative aims to create a cohesive, evidence-based strategy to unlock the potential of next-generation geothermal energy across the nation.
While conventional geothermal has long been a reliable renewable source in volcanic regions like Iceland and New Zealand, Canada is setting its sights on a more ambitious prize: tapping into deep geothermal heat using technologies borrowed from the oil and gas sector. This roadmap is not merely an academic exercise; it is a strategic blueprint intended to de-risk investment, foster innovation, and position Canada as a modern energy superpower.
The Quiet Revolution: Why Deep Geothermal?
To understand the significance of this roadmap, one must first understand the difference between conventional and deep geothermal energy.
Conventional geothermal systems typically rely on specific geological conditions—namely, permeable rock, abundant water, and heat close to the surface, usually within one to two kilometers. These sites are often marked by hot springs or geysers. Canada, while rich in geological diversity, has few naturally occurring conventional sites.
Deep geothermal, or next-generation geothermal, changes the equation. It involves drilling wells to depths of three to ten kilometers, where temperatures consistently reach 150 to 300 degrees Celsius, regardless of surface location. This means that geothermal energy is not a regional luxury but a national possibility. From the sedimentary basins of Alberta to the ancient Canadian Shield in Ontario and Quebec, deep heat exists everywhere. The only variable is the cost and technology required to reach it.
The Quiet Before the Heat: Why Now?
Canada has one of the most decarbonized electricity grids in the world, thanks largely to hydroelectric power. This success has inadvertently created a "green energy trap," where the perceived sufficiency of the status quo has historically stifled innovation in other renewables like geothermal.
Yet, the energy landscape is shifting. The rise of artificial intelligence data centers, the electrification of transportation, and the need to replace retiring fossil fuel baseload have forced a reckoning: hydro and intermittent wind and solar may not be enough to guarantee twenty-four-seven grid stability. Droughts have already reduced hydro output in parts of British Columbia and Manitoba, exposing the vulnerability of over-reliance on a single renewable source.
This is where deep geothermal enters the conversation. Unlike solar and wind, a geothermal plant operates with a capacity factor exceeding ninety percent, acting as an always-on, zero-emission baseload provider that enhances, rather than destabilizes, the grid. It occupies a tiny land footprint—roughly one-tenth that of solar per megawatt—and produces no combustion byproducts. For a country committed to net-zero by 2050, geothermal offers a rare combination of reliability, cleanliness, and dispatchability.
The federal funding is designed to solve a critical market failure: Canada lacks a cohesive data and policy ecosystem to de-risk private investment. The Canadian Deep Geothermal Coalition, launched in 2025, brings together nearly two dozen organizations—including developers, utilities, research institutions, and Indigenous communities—to address the "clear, shared path" that has been conspicuously absent. The roadmap they will produce is intended to answer three fundamental questions: where are the best resources, what technologies are most suitable, and what policy instruments are needed to bridge the gap between potential and production.
The Technology: Borrowing from the Oil Patch
The true insight of Canada's geothermal push lies not in reinventing the wheel, but in repurposing the internal combustion engine for a clean energy future. The expertise required for deep geothermal is, to a large degree, identical to that of the oil and gas sector: directional drilling, subsurface mapping, reservoir engineering, and well stimulation.
Canada has spent a century perfecting these crafts. Tens of thousands of oil and gas workers possess transferable skills that are directly applicable to geothermal development. The roadmap explicitly recognizes this synergy as a competitive advantage. Rather than treating geothermal as a replacement for fossil fuel jobs, it positions geothermal as a destination for those same workers as the energy transition accelerates.
Next-generation geothermal systems overcome the limitations of conventional methods, which rely on naturally occurring hot water reservoirs. Two technology families are central to Canada's roadmap.
The first is Enhanced Geothermal Systems, which borrow hydraulic fracturing techniques to create artificial reservoirs in hot, dry rock. Water is injected at high pressure to open existing fractures, creating a subsurface heat exchanger. Production wells then circulate fluid through this stimulated volume, extracting heat to generate electricity on the surface.
The second is Advanced Geothermal Systems, exemplified by closed-loop designs that use sealed circuits of fluid circulating within a wellbore. These systems require no fracturing, produce no induced seismicity risks, and can operate in virtually any geological setting. Because the working fluid never contacts rock, corrosion and scaling issues are dramatically reduced. Several Canadian companies have already deployed pilot-scale closed-loop systems, proving the concept in harsh northern conditions.
Both approaches share a common economic challenge: high upfront capital costs and near-zero fuel costs. Once a well is drilled, the heat is free. But drilling deep wells—three and a half to six and a half kilometers, or even down to ten kilometers—can cost tens of millions of dollars per well, with no guarantee of success. This risk profile is exactly what the roadmap aims to address through risk mitigation strategies, data sharing, and innovative financing mechanisms.
The Economic Calculus: Powering Millions of Homes
The scale of Canada's potential is genuinely staggering. Industry estimates suggest Canada has the latent capacity to generate enough geothermal electricity to power five million homes. The western sedimentary basin alone, spanning northeastern British Columbia, Alberta, and southern Saskatchewan, holds thermal resources that could yield thousands of megawatts of power. The Cordillera region—a belt of mountainous terrain running from British Columbia into Yukon—contains high heat flow and fault systems that are ideal for conventional geothermal.
But the opportunity extends beyond electricity. Direct-use geothermal—employing heat directly for industrial processes, greenhouse agriculture, district heating, or mineral extraction—represents an even larger near-term market. The oil sands, for example, require massive amounts of steam to extract bitumen. That steam is currently produced by burning natural gas. Substituting geothermal steam would slash emissions from one of Canada's most carbon-intensive industries while reducing operating costs over the long term.
The financial opportunity is immense. The roadmap will focus on building a world-class, Canadian-headquartered geothermal value chain. This includes not only power plant operators but also drill rig manufacturers, casing suppliers, downhole tool fabricators, consulting engineers, and financial services. For a country that has historically exported raw energy resources, geothermal offers a chance to export technology, expertise, and equipment to the dozens of other nations with similar deep-heat geology.
The Indigenous Dimension: Rights Holders, Not Just Stakeholders
Perhaps the most forward-thinking aspect of the coalition's initiative is its framing of Indigenous engagement. The roadmap process explicitly commits to engaging Indigenous communities not merely as "stakeholders" to be consulted, but as rights holders, owners, and decision-makers.
This distinction is critical. Across Canada, many Indigenous communities live in remote, diesel-dependent locations. They pay some of the highest energy prices in the country and suffer from the pollution and logistical risks of fuel deliveries. Geothermal offers a pathway to energy sovereignty: a reliable, locally controlled, zero-emission resource that does not require long transmission lines or volatile fuel shipments.
Several Indigenous communities are already leading the charge. One nation in British Columbia is advancing a project aiming to become one of Canada's first purely electricity-generating geothermal facilities. Another in the same province has received feasibility funding to explore geothermal resources on its traditional territory, signaling a model of clean energy sovereignty. The roadmap intends to follow the principles laid out in various Indigenous energy declarations, ensuring that perspectives which are often an afterthought become foundational to Canada's geothermal future.
The economic co-benefits are substantial. Geothermal plants have long operational lives—typically thirty to fifty years—providing stable royalty revenues, local employment, and capacity-building opportunities. For communities seeking to move away from resource extraction royalties that fluctuate with global commodity prices, geothermal offers a predictable, inflation-linked revenue stream.
The Roadblocks: Capital, Legislation, and Grid Dynamics
Despite the optimism, significant headwinds remain. The primary barrier is capital. Upfront drilling costs for deep wells are immense, running into the hundreds of millions of dollars for a commercial-scale project. The risk of a dry well—or a well that does not achieve sufficient flow or temperature—is non-trivial. Early-stage geothermal projects face a "valley of death" where exploration and confirmation drilling costs are too high for venture capital yet the projects are too risky for traditional project finance.
Current federal investment tax credits often exclude these specific drilling expenses, creating a distortion that leaves geothermal at a disadvantage compared to other renewables. Solar and wind projects, which face lower upfront risks, have benefited from generous tax incentives, while geothermal—arguably more valuable from a grid reliability perspective—has been left in a policy blind spot. The roadmap is expected to recommend targeted fiscal measures, such as exploration tax credits, loan guarantees, or a geothermal-specific production incentive.
Legislative fragmentation is another major hurdle. Only a handful of provinces have geothermal-specific legislation, leaving most of the country in a regulatory vacuum that chills investment. In provinces without a regulatory framework, it is unclear whether geothermal is classified as mining, oil and gas, or renewable electricity generation. Each classification carries different royalty regimes, environmental assessment processes, and land access rules. The roadmap will call for model legislation that provinces can adopt, reducing regulatory uncertainty and creating a consistent national playing field.
Grid integration presents a third challenge. In provinces dominated by cheap natural gas and subsidized hydro, geothermal struggles to compete on price without a carbon pricing mechanism that fully values its zero-emission baseload attributes. While federal carbon pricing exists, its trajectory beyond 2030 remains politically contested. Geothermal proponents argue that the resource should be compensated not only for the electricity it generates but for the reliability services it provides—frequency regulation, voltage support, and capacity reserves—which variable renewables cannot offer.
Finally, public perception and induced seismicity remain live issues. Enhanced Geothermal Systems, which involve hydraulic stimulation, can trigger small earthquakes. While these events are typically imperceptible at the surface, the experience of a handful of projects internationally has generated caution among regulators and nearby residents. Closed-loop systems avoid this risk entirely, but they are also more expensive per megawatt. The roadmap will need to navigate this trade-off transparently, recommending different technology pathways for different geological and social contexts.
The Cascade Institute's Role: Secretariat as Sense-Maker
The Cascade Institute, serving as the roadmap's secretariat, brings a unique interdisciplinary lens to the process. The institute specializes in complex, multi-stakeholder problems that span technology, policy, and social systems. Its executive director has framed the roadmap as an exercise in "translating Canada's strengths into real projects and long-term sector growth."
What this means in practice is that the roadmap will not be a static document. It will be a living strategy, updated as drilling results come in, as technology costs fall, and as policy windows open. The secretariat will coordinate working groups, synthesize technical reports, and facilitate consensus among competing interests—utilities that want power, drillers that want contracts, communities that want sovereignty, and governments that want emissions reductions.
This is a non-trivial governance challenge. The coalition includes actors with divergent incentives. An oil sands operator may want geothermal for steam-assisted gravity drainage, prioritizing temperature over electricity. A utility may want baseload power, prioritizing flow rate over temperature. An Indigenous community may want local control, prioritizing scale and ownership structure over technical optimization. The secretariat's job is to find overlapping zones of agreement and translate them into actionable recommendations.
International Context: Canada as Follower or Leader?
Globally, geothermal energy is experiencing a renaissance. The United States, through its own advanced geothermal research programs, has committed substantial funding to demonstration projects in Nevada, Utah, and Oregon. Germany, Japan, and Australia have all launched national geothermal roadmaps in the past five years. Private investment is flowing into startups developing millimeter-wave drilling, plasma pulse technology, and closed-loop systems.
Canada enters this race from behind but with distinct advantages. No other country has as deep a bench of cold-climate drilling expertise. No other country has as many oil and gas workers seeking transitional employment. And few countries have as large a gap between their clean energy goals and their baseload reliability needs. The roadmap is Canada's opportunity to leapfrog from zero to next-generation, rather than retracing the incremental steps taken by conventional geothermal leaders.
But timing is everything. If the roadmap takes too long to produce, or if its recommendations are ignored, Canadian firms will lose their first-mover advantage. The global geothermal supply chain is still nascent; the companies that build the first commercial deep geothermal plants in Canada will be well-positioned to export that model to the dozens of other nations with similar geology. Conversely, if Canada hesitates, those same export markets will be captured by American, Australian, or European competitors.
What Success Looks Like
The coalition has set an ambitious timeline. A draft roadmap is expected to be presented at a major international geothermal conference, with a final version released shortly thereafter. Success will be measured not by the document's publication but by what follows.
In the near term, success means the launch of at least two commercial-scale deep geothermal demonstration projects within three years of the roadmap's release. These projects would be co-funded by federal and provincial governments, with private sector cost-sharing. They would serve as learning laboratories, reducing drilling costs, validating resource assessment techniques, and building supply chain capacity.
In the medium term, success means the creation of a Canadian geothermal industry association, the adoption of model geothermal legislation by several provinces, and the inclusion of geothermal in federal clean electricity regulations as a qualifying resource. It also means the training of the first cohort of geothermal specialists through colleges and universities, building on existing petroleum engineering programs.
In the long term, success means geothermal providing five to ten percent of Canada's electricity by 2050, along with substantial direct-use heat for industrial decarbonization. It means Canadian geothermal technology and expertise being exported to countries across the globe, from Chile to Indonesia to Kenya. And it means the thousands of oil and gas workers who fear being left behind by the energy transition finding stable, well-paid careers in a sector that harnesses the planet's own internal furnace.
Conclusion: The Heat Beneath Our Feet
Canada's investment in a national geothermal roadmap is a tacit admission that the clean energy transition cannot rely on hydro and wind alone. It requires the gritty, deep-earth reliability that only geothermal can provide—the capacity to deliver power through calm nights, windless days, and drought-stricken river basins.
By formalizing this roadmap, backed by the Cascade Institute and the Canadian Deep Geothermal Coalition, Canada is finally aligning its world-class technical talent with a twenty-four-seven low-carbon future. The conversation around geothermal has shifted from "if" to "when" and from "how much" to "how fast."
The success of this initiative will depend on whether the government matches this planning with the substantial financial firepower required to drill deep. Roadmaps are necessary but not sufficient. They must be followed by budgets, by regulatory reforms, and by the political will to take risks on unproven resources. For an energy superpower facing a net-zero deadline, the heat beneath our feet is no longer just a geological curiosity. It is the next logical step in the nation's industrial evolution—a step that Canada has finally decided to take.
