Geothermal Energy Costs: Why Drilling Discipline Decides Bankable Megawatts

Geothermal Isn't Expensive: The Reservoir Always Has the Final Say Somewhere beneath a volcanic ridge, a drill bit is turning through rock that has not moved in two million years. It costs money every second it turns. And nobody on the surface — not the engineer, not the financier, not the minister who announced the megawatts — knows yet whether that well will produce steam or silence. That single moment explains almost everything people get wrong about geothermal energy. Geothermal is routinely described as expensive, slow, capital-hungry and haunted by drilling risk. Investors are reminded that tens of millions can disappear underground before a single megawatt reaches a grid. All of that is true. But it is not the whole truth. The uncomfortable question the industry keeps avoiding is this: is geothermal expensive, or is the way we develop geothermal making it expensive? Those are two completely different problems. One is geology. The other is us. Why Geothermal Refuses to Be...

UK Bolsters Grenada's Geothermal Ambition With €10 Million Investment

UK Allocates £10 Million to Accelerate Grenada’s Green Energy Transition

By: Robert Buluma



Grenada has received a significant boost in its journey toward sustainable energy solutions, thanks to a £10 million investment from the UK government. The announcement was made during a meeting between Baroness Chapman, the UK Minister for Latin America and the Caribbean, and Grenadian Prime Minister Dickon Mitchell in St. George’s.  

This funding will be directed toward Grenada’s Geothermal Energy Development Project, which aims to explore the viability of the country’s geothermal resources. If successful, this initiative could reduce Grenada’s heavy reliance on imported fossil fuels and lay the groundwork for locally sourced, cost-effective, and climate-resilient energy solutions.  

A Major Step Toward Energy Independence  

Baroness Chapman emphasized the importance of this investment, stating, *“I am thrilled to announce £10m in new funding, which is supporting Grenada’s efforts to reduce its reliance on fossil fuels and transition to a more sustainable, locally sourced energy future. The investment in geothermal energy will not only help to lower energy costs for households and businesses, but will also lead to lower carbon emissions, an essential step in tackling the climate crisis.”

For Caribbean nations like Grenada, which heavily depend on expensive imported fossil fuels, this investment comes at a crucial time. The average Caribbean household pays double the energy costs of consumers in the United States, a burden that stifles economic growth and leaves the region vulnerable to global energy price fluctuations.  

Prime Minister Mitchell expressed gratitude for the UK’s support, saying, “This funding will allow us to assess the geothermal potential of Grenada and take further steps toward building a clean, sustainable, and more affordable energy system for our country. We are excited about the possibilities this project holds for our country’s future.”

Unlocking Grenada’s Geothermal Potential  

The £10 million investment will fund critical assessments of geothermal resource viability, including drilling rotary exploratory wells. This phase is vital for de-risking the project and attracting private sector investments. Successful exploration could lead to the establishment of a geothermal power plant capable of displacing up to 55% of Grenada’s electricity generation from diesel, significantly enhancing energy security and reducing tariffs for businesses and households.  

Geothermal energy presents vast untapped potential in the Caribbean. However, high upfront exploration costs remain a significant barrier to private investment. Public funding, such as this, is essential to jumpstart geothermal initiatives, paving the way for greener and more affordable energy solutions.  

 A Broader Commitment to Climate Action  

This announcement is part of a larger £19.3 million renewable energy initiative by the UK across six Caribbean countries, including Grenada, Antigua and Barbuda, Dominica, Saint Lucia, and St. Vincent and the Grenadines. Since 2015, the UK has supported renewable energy and energy efficiency projects across the region.  

Baroness Chapman reiterated the UK’s dedication to combating climate change globally, stating, “Partnerships like this drive progress on the global ambition needed to keep global warming to no more than 1.5 degrees as called for by the Paris Climate Agreement.”

A Green Energy Future for Grenada  

Grenada’s geothermal project represents an opportunity to transition to a clean energy future while addressing pressing economic challenges. By reducing dependence on fossil fuels and fostering energy independence, the country can make strides toward a sustainable and climate-resilient economy.  

This collaboration between the UK and Grenada highlights the importance of international partnerships in achieving green energy goals. With continued investments in renewable energy, Grenada is poised to become a model for sustainability in the Caribbean region.  

With the latest findings from International Energy Agency, Its evident Geothermal is poised to be the most sought after source of clean and sustainable energy.

This is a key moment for Grenada and the Caribbean as a whole. As Grenada embarks on this transformative journey, the success of this project could inspire similar initiatives across the region. What do you think about Grenada’s geothermal energy potential?

COWI and Sinotech Advance Taiwan’s Super-Hot Geothermal Potential

COWI and Sinotech Team Up on Taiwan’s Super-Hot Geothermal Potential 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, geot...

GEL Technical Grade Lithium Milestone Boosts UK Geothermal Supply

GEL’s Technical-Grade Lithium Milestone Could Reshape UK Critical Minerals Supply Geothermal Engineering Ltd’s latest announcement is an important step for the UK’s lithium ambitions. The company says lithium carbonate produced from deep geothermal brine at United Downs now meets the 99.3% purity threshold for technical-grade material, which means it can be sold directly to battery supply chains without further refining.   Why this milestone matters This is significant because it moves geothermal lithium closer to commercial relevance, not just technical proof. A material that already meets market specification is much easier to integrate into downstream battery and industrial supply chains. It also strengthens the case that geothermal brines can support both clean power generation and critical minerals production from the same asset base.   For the UK, the timing is especially relevant. The government has set a target of meeting 10% of domestic critical mineral de...

Quaise Energy’s Project Obsidian in Oregon: The World’s First Commercial Superhot Geothermal Plant

The New Energy Frontier: Quaise Energy’s Superhot Geothermal Gambit in Oregon By Alphaxioms Editorial Team | September 4, 2026 In the high desert of Central Oregon, a project with implications far beyond Deschutes County is taking shape. Quaise Energy, now backed by a total of $280 million in funding, is advancing Project Obsidian, which it describes as the world’s first commercial superhot geothermal power plant . The company says the first phase is designed to deliver 50 MW by 2030, with a pathway toward 250 MW and ultimately more than 1 GW . Before the first megawatt reaches the grid, however, the project faces a local policy test: whether Deschutes County should grant a five-year property tax abatement under Oregon’s Rural Renewable Energy Development Zone Program. That decision is more than a routine incentive request. It is a referendum on how rural counties choose to support next-generation energy infrastructure and whether older incentive frameworks can accommodate a technolog...

Saudi Arabia AI Data Centers Adopt Strataphy PrimeLoop Cooling Technology

Strataphy Partners With HUMAIN to Deploy PrimeLoop Cooling Across Saudi Arabia’s AI Data Centers Saudi Arabia is moving rapidly to establish itself as a global artificial intelligence and data-center powerhouse, and one of the most important challenges facing that ambition is not simply how much computing capacity can be installed, but how efficiently that computing capacity can be cooled. At LEAP 2026, Strataphy announced a partnership with HUMAIN to deploy its PrimeLoop® cooling technology across HUMAIN’s data-center infrastructure in the Kingdom of Saudi Arabia. According to the announcement, the engagement represents the first deployment of its kind for PrimeLoop® in Saudi Arabia and is designed to address one of the fundamental constraints of large-scale AI infrastructure: thermal management. The partnership comes as HUMAIN works toward a target of approximately 6 GW of AI compute. At that scale, cooling becomes a strategic infrastructure issue rather than a conventional dat...

Mazama Energy Athena Drilling Milestone Boosts Superhot Rock Geothermal Economics

Mazama Energy’s Athena drilling milestone points to a new phase for superhot rock geothermal Mazama Energy says its Athena well at Newberry, Oregon reached 10,350 feet in 15 drilling days, cutting the drilling time to the same depth by 80% versus its 2025 result. The company says the performance supports a broader case for superhot rock geothermal as a lower-cost, scalable source of firm power.   A faster drilling result Mazama’s update is important because drilling speed is one of the biggest cost drivers in geothermal development. Reaching the same depth in 15 days instead of the much longer 2025 campaign suggests the team is learning quickly and improving operational efficiency. The company also reported instantaneous rates of penetration above 350 feet per hour and sustained rates above 130 feet per hour over extended intervals.   That matters because geothermal economics often hinge on whether drilling can be made predictable, repeatable, and cheaper over time. ...

Ireland’s Deep Heat: Surveying Geothermal Potential Beneath Dublin

Dublin’s seismic survey will map deep underground geology to assess geothermal potential, reduce uncertainty, and support future clean, local energy development Dublin is about to become a live laboratory for one of the clean energy questions of the decade: can the heat stored deep beneath the city help warm homes, offices, schools, and hospitals? The answer is not known yet, but the Dublin Seismic Survey is designed to find out by mapping the geology 2 to 3 kilometres underground with a safe, non-invasive method that has already been used successfully in other European cities . A city listening underground At street level, the survey may look deceptively simple: a specialist truck pauses at intervals, presses a vibration plate to the road, and sends controlled energy into the ground. That energy bounces off different rock layers and structures, then returns to sensors along the route, where it is recorded and processed into images of the subsurface . The process is built around precis...
