KenGen Risks Losing Olkaria Geothermal Wells Over Licence Error

KenGen Risks Losing Olkaria Wells Over 18-Year Licence Blunder Kenya Electricity Generating Company (KenGen) faces a serious legal and operational risk at Olkaria after an error in the coordinates of its geothermal licence left part of the company’s wells, steam infrastructure and other assets outside its legally recognised area. The licensing mistake, made nearly two decades ago, remains unresolved despite the Ministry of Energy and Petroleum acknowledging the problem in 2017.  The dispute has raised questions about the security of KenGen’s investments, the government’s management of geothermal resources and the potential consequences for Kenya’s electricity supply. Olkaria is the country’s most important geothermal centre and accounts for the overwhelming majority of Kenya’s installed geothermal generation capacity.  Licence Error Exposes Strategic Assets The problem dates back to September 19, 2008, when the Ministry of Energy and Petroleum issued KenGen a licence covering ...

Geothermal Data Centers: Rewriting the Water-Energy Equation

Thirsty Servers, Silent Reservoirs: Can Geothermal Power the Water-Smart Data Center Era?


The digital economy runs on an invisible infrastructure—rows of servers humming inside vast data centers, processing everything from financial transactions to artificial intelligence models. But beneath this digital revolution lies a growing, often overlooked tension:
water.

Recent projections warn that data centers could consume as much freshwater as tens of millions of people by 2030. Whether the exact figure is 30, 40, or 46 million, the signal is unmistakable: the world’s data infrastructure is becoming a major water consumer.

At the same time, a quieter force is emerging from beneath the Earth’s surface—geothermal energy—with the potential not only to power data centers, but to fundamentally reshape their water footprint.

This is not just a story about energy. It is a story about resource convergence—where water, heat, electricity, and digital demand collide—and how geothermal could unlock a radically different path forward.


The Hidden Water Cost of the Digital Age

When people think about data centers, they think about electricity. Rarely do they think about water.

Yet water is central to data center operations in two major ways:

1. Cooling the Heat

Modern data centers generate enormous heat. To maintain optimal operating temperatures, many facilities rely on evaporative cooling systems. These systems work by evaporating water to remove heat—but that process comes at a cost:
water is lost to the atmosphere, continuously.

In large hyperscale facilities, this can mean:

  • Millions of gallons of water per day
  • Significant strain on local water supplies, especially in arid regions

2. Powering the Power

Even when water isn’t used inside the data center, it is often used outside it—in the generation of electricity.

Thermal power plants (coal, gas, nuclear) require water for cooling, meaning:

  • A large portion of a data center’s true water footprint is indirect
  • In some cases, up to 70–75% of total water use is tied to electricity generation

The AI Acceleration Problem

The rise of artificial intelligence is supercharging this issue.

Training large AI models and running inference at scale:

  • Increases compute density
  • Raises thermal loads
  • Requires more aggressive cooling strategies

At the same time, data centers are increasingly being built in:

  • Hot climates
  • Water-stressed regions
  • Emerging digital hubs

This creates a paradox:

The regions most attractive for digital growth are often the least able to support its water demands.


Geothermal Energy: More Than Just Power

Geothermal energy is often framed as a clean, baseload power source. That alone makes it attractive for data centers, which require:

  • 24/7 reliability
  • Stable energy supply
  • Low carbon emissions

But geothermal’s real advantage goes deeper—it is uniquely positioned at the intersection of energy and water systems.


How Geothermal Reduces Water Consumption

1. Eliminating Evaporative Cooling Dependency

The single largest water consumer in data centers is evaporative cooling.

Geothermal enables:

  • Closed-loop cooling systems
  • Geothermal-assisted heat exchange
  • Absorption chilling using geothermal heat

Instead of evaporating water, these systems:

  • Transfer heat through sealed systems
  • Reuse fluids continuously

Impact:
Water losses can drop by 60–80% compared to conventional cooling towers.


2. Slashing Indirect Water Use from Electricity

Traditional electricity sources—especially thermal plants—are water-intensive.

Geothermal systems:

  • Reinject fluids back underground
  • Operate in closed or semi-closed loops
  • Require minimal freshwater withdrawal

Advanced closed-loop systems go even further:

  • No water loss to evaporation
  • No interaction with surface water systems

Impact:
A further 10–20% reduction in total water footprint through cleaner energy sourcing.


3. Leveraging Subsurface Thermal Stability

One of geothermal’s most underappreciated advantages is temperature stability.

Underground environments maintain relatively constant temperatures year-round. This allows:

  • Pre-cooling of air or fluids
  • Reduced reliance on energy- and water-intensive cooling cycles

Impact:
Lower overall cooling demand → reduced water usage.


4. Enabling Non-Freshwater Cooling Systems

In geothermal regions, operators can utilize:

  • Geothermal brine
  • Recycled wastewater
  • Industrial water streams

Impact:
Even when water is used, it does not compete with drinking water supplies.


5. Powering Desalination and Water Recycling

Geothermal energy can support:

  • Desalination plants
  • Advanced water treatment systems

By providing both heat and electricity, geothermal enables:

  • Lower-cost desalination
  • Continuous water recycling loops

This opens the door to:

  • Water-neutral or even water-positive data centers

Can Geothermal Really Achieve 85% Water Reduction?

The often-cited 85% reduction is not a baseline—it is a best-case scenario.

It becomes achievable when multiple strategies are integrated:

Component Water Reduction Contribution
Eliminating evaporative cooling 60–80%
Switching to geothermal power 10–20%
Recycling & efficiency gains 5–10%

Total potential reduction:
👉 Up to ~85%, in optimized systems


Designing the Next-Generation Data Center

The real opportunity is not incremental improvement—it is system redesign.

A geothermal-powered, water-smart data center would look like this:

Energy

  • 100% geothermal baseload power
  • Zero reliance on water-intensive thermal plants

Cooling

  • Air-cooled or hybrid systems
  • Geothermal-assisted thermal regulation
  • No cooling towers

Water

  • Recycled wastewater loops
  • Desalinated supply (if needed)
  • Minimal freshwater intake

Heat Reuse

  • Waste heat redirected to:
    • Agriculture
    • District heating
    • Industrial processes

Strategic Opportunity: Africa and the Rift Valley

For regions like East Africa, this is more than theory—it is a competitive advantage.

The Great Rift Valley hosts some of the world’s richest geothermal resources, creating a unique opportunity to:

  • Build data centers powered by geothermal from day one
  • Avoid the legacy inefficiencies of water-intensive designs
  • Position the region as a hub for sustainable digital infrastructure

Challenges That Cannot Be Ignored

Geothermal is powerful—but not a silver bullet.

1. High Upfront Costs

Drilling and exploration require:

  • Significant capital
  • Geological risk

2. Location Constraints

Geothermal resources are:

  • Site-specific
  • Not evenly distributed globally

3. Infrastructure Integration

Designing integrated systems requires:

  • Cross-sector collaboration
  • New engineering approaches

The Bigger Picture: Resource Convergence

What we are witnessing is not just a data center problem. It is a systems challenge:

  • Energy demand is rising
  • Water stress is increasing
  • Digital infrastructure is expanding

These trends are converging.

Geothermal stands out because it addresses multiple constraints simultaneously:

  • Clean energy
  • Low water use
  • Thermal stability
  • Circular resource potential

Conclusion: From Water-Intensive to Water-Intelligent

The warning that data centers could rival the water use of tens of millions of people is not alarmist—it is directionally accurate.

But it is not inevitable.

With geothermal, the narrative can shift:

  • From consumption to efficiency
  • From competition to coexistence
  • From linear use to circular systems

The future data center will not just be powered differently—it will be designed differently.

And in that redesign, geothermal is not just an energy source.

It is a foundational technology for a water-smart digital age.

Jicarilla Apache Geothermal Study Wins $2.5 Million Grant

Jicarilla Apache Nation Launches $2.5 Million Geothermal Feasibility Study The Jicarilla Apache Nation in northern New Mexico has launched a major investigation into its geothermal energy potential after receiving a $2.5 million grant from the State of New Mexico. The funding will support a detailed feasibility study examining whether underground heat resources on tribal lands could be developed for electricity generation, direct heating, or other energy applications. The initiative represents an important step in the Nation’s efforts to understand and diversify its energy resources. Although the Jicarilla Apache Nation has not yet committed to building a geothermal facility, the study could provide the geological, technical, and economic information required for future investment decisions. The project is particularly significant because the Nation already has extensive experience with subsurface exploration through its oil and gas activities. Existing geological records, drilling inf...

Ijen vs Zanskar: Blind Geothermal Energy Discovery and Development

Ijen’s Blind Geothermal System vs. Zanskar’s AI-Discovered Resources: Two Models for Finding Hidden Heat The geothermal industry is entering a new phase in which the most valuable resources may no longer be the fields marked by obvious hot springs, geysers, fumaroles, or steaming ground. Increasingly, developers are targeting “blind” or hidden geothermal systems,reservoirs that lack clear surface expressions but can still contain the temperature, permeability, and fluid needed for commercial power generation. Two examples illustrate how different parts of the industry are approaching this challenge. In Indonesia, the Blawan-Ijen geothermal field in East Java was developed through geological interpretation, magnetotelluric imaging, conceptual modelling, and drilling. The project is now operating commercially, with its first phase delivering approximately 35 MW to the Java grid under a 30-year power purchase agreement.  In the United States, Zanskar Geothermal & Minerals is using...

Through its Vercana subsidiary, the company is also using electric drilling equipment designed to support the development of its Lionheart project in Germany’s Upper Rhine Valley. The approach differs from the conventional geothermal model represented by Ormat Technologies, whose core business remains geothermal power generation, equipment, project development and energy storage rather than commercial lithium recovery from geothermal brine.  The economic question is broader than whether an electric drilling rig costs less to operate than a diesel rig. The more important issue is whether electric drilling, geothermal energy and direct lithium extraction can create a more valuable integrated project than a conventional geotherm...

Western Geothermal Power Transmission Roadmap Toward 2030

Geothermal Power in the Western United States: A Transmission and Planning Roadmap to 2030 Introduction The Western United States is approaching a decisive period for geothermal power. Electricity demand is rising because of data centers, industrial electrification, population growth, electric vehicles and the replacement of retiring fossil-fuel generation. At the same time, utilities are under growing pressure to add clean resources that can operate reliably when solar and wind output declines. Geothermal power is well positioned to fill this role. Unlike weather-dependent generation, geothermal plants can provide firm electricity for long periods, support grid reliability and reduce the amount of storage required in deeply decarbonized power systems. However, the industry’s expansion will depend on more than subsurface heat and drilling technology. By 2030, transmission access, resource planning, project finance, permitting and utility procurement will determine whether geothermal be...

Billionaire Families Bet on Advanced Geothermal Energy Investments

Billionaire Geothermal Families Bet on Geothermal Billionaire families and private investment offices are placing increasingly large bets on geothermal energy, especially on technologies designed to make the resource available in more locations. Their investments are helping finance enhanced geothermal systems, advanced drilling, closed-loop designs, and other approaches that could transform geothermal from a regionally concentrated power source into a globally scalable clean-energy industry. The investment surge reflects a broader change in the energy market. Electricity demand is rising because of artificial intelligence, data centers, industrial electrification, electric vehicles, and the expansion of digital infrastructure. At the same time, utilities and large corporations need power that is reliable around the clock. Solar and wind remain essential to the clean-energy transition, but their output varies with weather and time of day. Geothermal could complement these technologies ...

Next-Gen Geothermal Funding 2026: VCs, Banks, Government Capital

Who Is Really Funding Next-Gen Geothermal in 2026? Next-generation geothermal has moved beyond laboratory research into a capital-intensive commercialization phase. In 2026, the most important financing is no longer coming from one investor category: venture capital funds are financing drilling, subsurface modelling and hardware; strategic energy companies are providing equipment, project access and market credibility; banks are beginning to lend against contracted projects; and governments are absorbing exploration and first-of-a-kind technology risk. The strongest financing activity is concentrated in the United States and Canada, but Europe is becoming increasingly important through Germany-based deployment, European Union grants, UK innovation support, and strategic participation from European energy companies. The central investment question is changing from “Can this technology work?” to “Can the developer deliver repeatable, financeable projects at commercial cost?” The 2026 fun...

Alberta Geothermal Startup Phase Secures Funding for High-Temperature Drilling Sensors

Alberta’s Phase Targets a Critical Geothermal Drilling Barrier With High-Temperature Sensors Alberta is using its deep oil-and-gas expertise to pursue a new opportunity beneath the surface: geothermal energy. Among the companies receiving support through Emissions Reduction Alberta’s Drilling Technology Challenge is Edmonton-based Phase Advanced Sensor Systems Corp., which is developing a high-temperature downhole pressure sensor for enhanced geothermal systems. The project addresses a problem that could determine whether deep geothermal energy becomes commercially viable: operators need reliable, accurate information from wells exposed to extreme heat and pressure. Phase plans to demonstrate a sensor capable of operating at temperatures above 200°C, with testing planned at 200°C, 250°C and 275°C.  The project has a total value of approximately C$1.57 million, including C$420,000 in ERA funding, according to Alberta’s project information.  Dealroom reported the award as approx...

Unlocking Impermeable Geothermal Reservoirs: Hydraulic Stimulation, Menengai and Olkaria

Unlocking the Impermeable Reservoir: Lessons from a 30-Year Reservoir Engineer An Alphaxioms interview with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Context: Menengai East and Olkaria Central. Every geothermal developer knows the moment.  The rig is gone and the money is spent. The well is drilled to depth, the temperature is there, and then the well will not flow. The heat is real, but the connection between the well and the reservoir is not. Wells like this sit at the centre of one of the most important questions in geothermal development: what do you do with a tight reservoir? Walk away and drill again, or find a way to unlock what is already there? To explore the question, Alphaxioms spoke with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Richard brings 30 years of global experience in geothermal energy.  We framed our questions around two settings, Menengai East and Olkaria Central, and asked him how ...

Menengai Geothermal Project Delays Expose Kenya’s Broken Steam Supply Model

Menengai’s Broken Promise: How Kenya’s Geothermal Model Lost the Steam Thematic image of the Olkaria Geothermal Field  Kenya’s Menengai geothermal project was sold as a model of modern public-private partnership. The state would carry the difficult and expensive burden of geothermal exploration and drilling. Private power producers would then build, own and operate power plants. Geothermal Development Company would supply the steam; the independent power producers would convert it into electricity; Kenya Power would buy the output. On paper, the arrangement was elegant. In practice, Menengai has exposed a far more uncomfortable reality: Kenya’s public steam-supply model is not delivering the certainty it promised. Menengai Phase I was designed to produce 105 megawatts from three 35 MW plants. GDC’s own project page says the three plants were awarded to Globeleq Menengai Geothermal, Sosian Menengai Geothermal Power and OrPower Twenty Two under a build-own-operate structure. Yet the ...
