Global Geothermal Power: Policies, Funding, Wells, Strengths, Opportunities and Barriers Geothermal is moving into a broader investment cycle. In 2026, the story is no longer limited to volcanic power plants in a few classic markets; it now includes enhanced geothermal systems, closed-loop designs, district heating, superhot rock, lithium from brines and industrial heat. Across the United States, Canada, Germany, the United Kingdom, Australia, New Zealand, Japan, Iceland, France and Italy, the sector is being shaped by a simple question: who is de-risking the first wells, and who is ready to finance the next ones? United States: the next-generation testbed The United States has the broadest geothermal innovation ecosystem in this group, with a mature conventional base in the West and a fast-growing next-generation pipeline. The main policy signal in 2026 is the Department of Energy’s US$171.5 million funding opportunity for next-generation geothermal field-scale tests, exploration...
Taiwan’s geothermal story is moving from possibility to execution, and the COWI-Sinotech collaboration is a sign that the sector is entering a more serious phase of development. The partnership is focused on unlocking super-hot geothermal resources, which could improve project economics and expand the country’s clean-energy options.
Introduction
Geothermal has long been one of Taiwan’s most intriguing renewable resources because the island sits on active tectonic terrain with strong heat potential. What has held the sector back is not a lack of heat, but the difficulty of converting that heat into bankable projects at scale. The new collaboration between COWI and Sinotech points to a more technical, internationally connected approach to solving that problem.
Why Taiwan Matters
Taiwan has ambitious decarbonization goals, and geothermal fits neatly into the need for firm, low-carbon power. Unlike solar and wind, geothermal can deliver electricity around the clock, which makes it especially attractive in a system that needs reliability as well as renewables.
The country also has a strong industrial base and deep engineering capability, which matters for drilling, surface infrastructure, and project integration. That combination of market need and technical capacity makes Taiwan more than just another geothermal prospect; it is a potential test case for broader Asian geothermal development.
“Super-hot” geothermal resources refer to very high-temperature underground conditions that can deliver much more energy per well than conventional geothermal systems. That matters because one of geothermal’s biggest challenges is cost, and higher temperatures can improve efficiency and potentially reduce the number of wells needed for a project.
This is where the Taiwan opportunity becomes especially interesting. If super-hot resources can be proven and developed successfully, they could change the economics of geothermal in a way that conventional projects often cannot.
Role of COWI
COWI brings international geothermal experience and a strong engineering profile to the table. Its broader renewable-energy track record in Taiwan and elsewhere suggests it is positioning itself as a technical partner for difficult infrastructure and energy projects. The company has highlighted decades of infrastructure work in Taiwan and geothermal experience across many countries, including major projects in Iceland.
That background matters because geothermal development is not just about drilling a hole and producing steam. It requires subsurface analysis, plant design, grid integration, civil works, and long-term project management. A firm with deep engineering credentials can help reduce execution risk, which is often one of the biggest barriers in geothermal finance.
Role of Sinotech
Sinotech’s involvement is equally important because local expertise can make or break geothermal projects. Taiwan-specific geological knowledge, permitting familiarity, and on-the-ground implementation capability are essential in a sector that depends heavily on site conditions and stakeholder coordination. A local partner can also help bridge the gap between international technical concepts and domestic project realities.
That combination of global and local capability is often what investors want to see. It signals that the project is not just technically ambitious, but also grounded in practical delivery.
Even with strong resource potential, geothermal projects are capital-intensive and slow to develop. Exploration drilling is expensive and risky, and many projects never move beyond the early stage because subsurface uncertainty makes lenders cautious. This is one reason geothermal has often lagged behind solar and wind in deployment, despite its attractive operating profile.
A collaboration like this can help by reducing technical uncertainty and improving project credibility. When a project has experienced engineering partners, better resource evaluation, and a clearer development pathway, it becomes easier to attract financing and investor interest. In geothermal, confidence is often as important as temperature.
Taiwan’s energy transition creates a natural opening for geothermal. The country needs cleaner baseload power, and geothermal can support grid stability in a way intermittent renewables cannot. That makes it strategically useful, not just environmentally desirable.
There is also a broader regional signal here. If Taiwan can establish workable models for super-hot geothermal development, other Asian markets with similar geological promise may take notice. That could help create a pipeline of projects, suppliers, and service providers around advanced geothermal technologies.
The opportunity is real, but the technical risks are also significant. Super-hot geothermal environments can be extremely challenging for drilling tools, well materials, and long-term plant operation. High temperatures and harsh underground conditions increase engineering complexity and can push costs higher if not managed carefully.
That is why partnerships like COWI and Sinotech matter. These projects require not just optimism, but detailed subsurface studies, robust engineering design, and practical risk management. In geothermal, the difference between a promising site and a working plant is usually found in the details.
Broader Industry Meaning
This partnership reflects a larger shift in geothermal development worldwide. The industry is moving beyond traditional hydrothermal fields toward next-generation systems that aim to unlock hotter, deeper, and more difficult resources. Taiwan’s super-hot prospect sits directly inside that trend.
For developers, investors, and policymakers, the message is clear: geothermal is becoming more advanced, more technical, and potentially more scalable. If the Taiwan initiative progresses well, it could strengthen the case for super-hot geothermal as a serious clean-power pathway rather than a niche concept.
Conclusion
The COWI-Sinotech partnership is important because it brings together international engineering depth and local market knowledge at a moment when Taiwan is looking for dependable clean energy. Its focus on super-hot geothermal resources could help move the sector from theory toward investable reality.
For Taiwan, this is about more than one project. It is about proving that advanced geothermal can work in a challenging market and become part of a broader low-carbon power strategy.
