Saudi Arabia Vouches on Red Sea Geothermal Rich Area To Meet Its Energy Demands

Unlocking Geothermal Energy in Saudi Arabia: From Geology to Techno-Economic Analysis

By: Robert Buluma


Saudi Arabia is poised to become a global leader in renewable energy, with geothermal energy emerging as a viable and sustainable option. While the Kingdom has long relied on fossil fuels, the nation's ambitious Vision 2030 plan highlights a shift towards clean energy, such as wind, solar, and now geothermal power.

The Untapped Potential of Geothermal Energy in KSA

Geologically, Saudi Arabia is endowed with significant geothermal energy resources, particularly along the Red Sea Rift Basin. This area is characterized by high heat flow from the Earth's depths, offering an ideal setting for geothermal energy development. These resources can provide sustainable baseload energy for various applications, including electricity generation, district heating and cooling, and water desalination—critical in a region where water scarcity is a pressing issue.

By tapping into geothermal resources, Saudi Arabia can reduce its reliance on oil for power generation, a move that aligns with the country's goal of lowering carbon emissions and advancing a circular carbon economy. Notably, geothermal energy, when combined with Carbon Capture, Utilization, and Storage (CCUS) technology, can create a dual benefit: clean energy production and efficient carbon management.

Innovative Research at KAUST

At the forefront of this initiative is the Computational Earthquake Seismology (CES) Research Group at King Abdullah University of Science and Technology (KAUST). The group is focused on unlocking geothermal energy potential along the Red Sea by leveraging advanced tools to create 3D geological models and conduct simulations. Their research targets key locations like Al-Lith and Al-Wajh, as well as sites near the Kingdom’s visionary Giga Projects, including the Red Sea Development Project and NEOM.

Embedded in the Circular Carbon Initiative at KAUST, the CES team collaborates with prominent experts and research centers such as ANPERC to explore sustainable ways to harness low-to-medium temperature hydrothermal resources. By combining geology with techno-economic analysis, they aim to provide cost-efficient and environmentally friendly energy solutions.

The Strategic Importance of Geothermal Energy

Saudi Arabia's reliance on fossil fuels for electricity generation and water desalination has long been unsustainable, both economically and environmentally. As the country faces rapid socio-economic growth and increasing water demand, alternative solutions are imperative. Geothermal energy offers several strategic advantages:  


1. Baseload Energy Supply: Unlike solar and wind energy, geothermal provides a continuous energy supply, reducing reliance on fossil fuels.

2. Water Desalination: With the Red Sea as a natural resource, geothermal energy can support large-scale desalination projects, ensuring a sustainable water supply.

3. Climate Action: By reducing carbon emissions and integrating with CCUS, geothermal energy supports the Kingdom's global commitments to climate change mitigation.

Techno-Economic Feasibility

One of the CES team’s landmark projects is the evaluation of a hydrothermal doublet system in Al-Wajh. This system assesses both the technical and economic feasibility of extracting and utilizing geothermal resources. By modeling the 3D thermal structure and reservoir characteristics, researchers can determine optimal drilling locations and energy outputs, ensuring maximum efficiency and sustainability.

A Visionary Future

The shift towards geothermal energy is more than just a scientific pursuit; it is a testament to Saudi Arabia's commitment to innovation and sustainability. As the Kingdom pioneers geothermal development in the region, the potential for economic diversification, environmental conservation, and energy security becomes a tangible reality.

KAUST’s efforts embody the late King Abdullah’s vision of being a "beacon for peace, hope, and reconciliation" by addressing global challenges through science and engineering. With state-of-the-art research and collaboration, Saudi Arabia is not only embracing renewable energy but also setting a precedent for sustainable development in the Middle East and beyond.

GA Drilling: Advanced Geothermal Drilling Technology, Deep Rock Innovation, and Clean Energy Financing

GA Drilling : Deep Drilling Technology, Financing, and Geothermal Scale-Up Image: A GA Drilling Bit GA Drilling is one of the more important technology companies in the geothermal sector because it is trying to solve a problem that has limited geothermal growth for decades: the cost, complexity, and risk of drilling deep wells in hard rock. Rather than operating a geothermal power plant itself, the company focuses on the drilling side of the value chain, developing technologies that can make deep geothermal wells faster, cheaper, and more reliable to build. That positioning gives it a different role from most geothermal developers, and it also makes it strategically significant for the future of clean baseload energy. The geothermal industry has always been constrained by subsurface uncertainty. Developers know where the heat is in a general sense, but they still must drill through high-temperature, abrasive, fractured, and often unpredictable rock to get there. In many projects, dril...

EGS Market Size and Investment Outlook

Enhanced Geothermal Systems (EGS) Market Size and Investment Outlook to 2034 Enhanced Geothermal Systems are at an inflection point. For years, EGS sat in the “promising but pre‑commercial” category of clean technologies, constrained by drilling cost, subsurface risk, and limited policy attention. That picture is now changing as next‑generation geothermal developers raise larger rounds, sign serious offtake agreements, and move projects from concept to execution.   At the same time, global demand for firm, low‑carbon power is rising faster than conventional geothermal can supply. Thermal plants are retiring, grids need 24/7 clean electricity, and policymakers are discovering that weather‑dependent renewables cannot carry the entire load alone. EGS is emerging as one of the few technologies capable of delivering baseload clean power using a resource available almost everywhere: deep, hot rock. Current EGS Market Size – Small but Strategic In absolute terms, the EGS market is s...

Exergy Gemini Turbine vs Ormat Ormega100: Geothermal Binary Power Comparison

Exergy Gemini Turbine vs Ormat Ormega100: Two Different Paths to Geothermal Scale image : a thematic view of a geothermal turbine "blade" Geothermal power is entering a new phase. Two of the most important announcements in the sector point to larger, more standardized, and more commercially viable binary geothermal systems: Exergy’s Gemini Turbine and Ormat’s Ormega100 . At first glance, both machines promise major gains in scale, but they are not trying to solve the same problem in exactly the same way. Gemini is built around a high-capacity radial outflow turbine architecture that can deliver up to 60 MWe per shaft, while Ormega100 is designed as a 100 MW binary surface power unit intended to accelerate enhanced geothermal system commercialization. For project developers, utilities, and data-center buyers looking for firm clean power, the comparison matters because it reveals two competing ideas about how geothermal should grow. Exergy is emphasizing turbine architectur...

Enhanced Geothermal Systems (EGS) Induced Seismicity: Can We Engineer Earthquakes Safely?

Enhanced geothermal systems are one of the few realistic paths to firm zero carbon power at scale, but they work by deliberately changing stresses in the crust, so induced seismicity is not a bug; it is a built‑in consequence that we have to manage, not eliminate. Image: geothermal wells of power The real question is whether we can design and regulate EGS so that most earthquakes stay tiny and useful as a reservoir diagnostic, and rare felt events stay within a risk envelope society will accept, with clear rules on who pays when something still goes wrong. EGS and induced seismicity Enhanced geothermal systems increase permeability in hot but relatively tight rock by injecting fluid under pressure, which raises pore pressure and shifts effective stresses on pre‑existing fractures and faults. When those faults are close to failure, even modest pressure changes can trigger slip, generating induced seismic events that range from microquakes only instruments detect to felt earthquakes like...

Geothermal Project Finance Structuring: SPVs, Mezzanine Debt, Blended DFI Finance and Contingent Capital for Drilling Risk

Geothermal Project Finance Structuring: SPVs, Mezzanine Debt and Blended Capital for Drilling Risk Image : A depiction of a geothermal complete project  Geothermal power sits in an awkward place on the project finance spectrum. It behaves like long‑lived infrastructure once it’s operating, but it looks like frontier exploration during the early drilling phase. To build bankable deals in that environment, developers and investors have had to invent a toolkit of SPV structures, mezzanine drilling tranches, blended public–private finance and contingent instruments that allocate subsurface risk without blowing up returns. This is not just a technicality for lawyers and bankers. The way geothermal deals are structured determines whether otherwise viable resources ever reach financial close. It also shapes how much upside sponsors keep via GP carry, how quickly equity can recycle, and how development platforms position themselves in a crowded clean‑energy pipeline. Why geothermal is stru...

How AI-Powered Digital Twins Are Transforming Geothermal Reservoir Management

Geothermal Reservoir Digital Twins: How AI Is Transforming Reservoir Management Image : Thematic image of a geothermal heat pump Artificial intelligence and digital twins are quietly rewriting the playbook for geothermal reservoir management. They turn scattered subsurface data into living, predictive models that help operators boost output, cut drilling risk, and extend the productive time. How Geothermal Digital Twins Are Making Reservoirs Smarter, Safer, and More Profitable For decades, geothermal development has been constrained by one brutal fact: you can’t see 3 km underground. You infer, you model, you hope—and sometimes you drill into a dry or underperforming reservoir. AI‑powered geothermal digital twins change that equation by continuously updating subsurface models with real‑time data, making the invisible reservoir behave like a transparent, responsive system. In practice, geothermal digital twins are dynamic software replicas of wells, reservoirs, and surface facilities th...

The "Heat-as-a-Service" (HaaS) Business Model: Geothermal Without the CAPEX Nightmare

Heat-as-a-Service takes geothermal from a capital-intensive power project to a financeable, contract-based heat utility: instead of selling electrons, you sell stable, decarbonized heat under long-term contracts that match what industrial customers and investors actually want. Image: A thematic picture of a geothermal power plant By shifting risk and ownership away from end users and toward specialised developers and infrastructure capital, it can unlock geothermal in markets where electricity tariffs are low but demand for reliable, low-carbon process heat is strong. From kWh to “heat-as-a-service” Traditional geothermal projects earn revenue by selling electricity into a grid, often at wholesale prices that barely cover high up-front drilling and plant costs unless there is a feed-in tariff or premium.Many industrial users, however, do not need electricity; they need heat for processes like brewing, greenhouse climate control or pulp and paper production, and they currently buy that ...
