Prometheus Hyperscale’s Geothermal Strategy: 2025 Analysis of a Hybrid Energy Pivot

Industry Adoption: How Prometheus Hyperscale Is Commercializing Its Hybrid Energy Model

Prometheus Hyperscale has shifted from a general sustainable infrastructure developer to a pragmatic provider focused on speed-to-market for AI clients, using a hybrid energy model that leverages natural gas and carbon capture under a “geothermal” brand.

• Between 2021 and 2024, the company, formerly Wyoming Hyperscale, promoted a vision centered on co-locating data centers with dedicated clean energy, highlighting a “proprietary geothermal technology” for zero-water cooling and a non-binding letter of intent with Oklo for nuclear power.
• In 2025, this strategy materialized into a more concrete, hybrid approach; the 1.2 GW flagship project in Evanston, Wyoming, is explicitly powered by natural gas from PureWest Energy combined with carbon capture, utilization, and storage (CCUS) from Frontier Carbon Solutions to achieve a “zero-carbon” goal.
• This model was replicated for its Texas expansion, where a partnership with Conduit Power will deploy up to 300 MW of behind-the-meter natural gas and battery solutions as a “bridge” power source to accelerate market entry ahead of grid-scale renewable integration.
• The company’s “geothermal” branding brilliantly conflates its innovative water-free liquid cooling system with baseload power generation, successfully projecting an image of 100% clean energy while pragmatically using fossil fuels with offsets to meet immediate AI power demands.

Geographic Focus: Prometheus Hyperscale’s Strategy in Wyoming and Texas

Prometheus Hyperscale has concentrated its development activities in Wyoming and Texas, selecting these states for their favorable energy resources and regulatory environments.

• From 2021 to 2024, the company’s entire focus was on its flagship Evanston, Wyoming, project, establishing the state as its strategic cornerstone for developing massive, energy-integrated data infrastructure.
• In 2025, Prometheus Hyperscale expanded aggressively into Texas through a key partnership with ENGIE to co-locate data centers with existing renewable energy assets, signaling a strategy of entering markets with established clean energy infrastructure.
• Wyoming remains the hub for its most ambitious projects, including the 1.2 GW campus in Evanston and the 1.5 GW carbon-negative project in Casper, leveraging the state’s natural gas reserves and potential for carbon sequestration.
• The move into Texas, a water-scarce region, validates the strategic value of the company’s zero-water geothermal cooling technology, which serves as a key enabler for market entry where competitors face environmental constraints.

Technology Maturity: Validating Geothermal Cooling and Hybrid Power at Scale

Prometheus Hyperscale’s core technology is its proprietary water-free cooling system, which has now moved from a conceptual advantage to a commercially validated enabler for its hybrid energy projects.

• During the 2021-2024 period, the company’s “proprietary geothermal technology” was primarily a marketing and branding tool, presented as a core part of its future sustainable data centers but without detailed public validation.
• By 2025, the technology has been clearly defined in commercial agreements as a ground-source heat exchange or aquifer-based *cooling* solution, not a power source, enabling zero water use in its facilities.
• The maturity of this cooling system is validated by its central role in the Texas expansion strategy, where water conservation is a critical operational and regulatory concern, giving Prometheus Hyperscale a distinct competitive advantage.
• Simultaneously, the company is deploying mature, market-ready energy technologies like natural gas generation and CCUS as its primary power source, demonstrating a pragmatic approach that prioritizes immediate project execution over reliance on nascent power technologies.

Forward-Looking Insights: 2025 Outlook for Prometheus Hyperscale

The critical action to monitor for Prometheus Hyperscale is the execution of its natural gas-plus-CCUS power model in Wyoming, as its success will validate the company’s entire strategy of providing rapid, gigawatt-scale capacity for the AI industry.

• Watch for construction milestones on the 1.2 GW Evanston campus, specifically the deployment of natural gas power infrastructure and the initial operational results from Frontier Carbon Solutions’ CCUS facilities.
• The deployment of the first 300 MW of “bridge” power in Texas by Conduit Power will be a key indicator of the company’s ability to execute its speed-to-market strategy in a new geography.
• Progress on the 1.5 GW carbon-negative data center with Spiritus will signal whether integrating direct air capture with data center operations is a commercially viable model for deep decarbonization.
• The successful pilot of XL Batteries’ organic flow battery technology would validate a crucial component of the long-term vision for achieving 24/7 renewable power and trigger offtake agreements for 2028.

Frequently Asked Questions

Is Prometheus Hyperscale actually using geothermal energy to power its data centers?
No, not for primary power generation. The company uses the ‘geothermal’ brand to refer to its proprietary water-free cooling system, which utilizes ground-source heat exchange. For power, its 2025 strategy explicitly relies on a hybrid model, using natural gas from partners like PureWest Energy combined with carbon capture, utilization, and storage (CCUS) to achieve its ‘zero-carbon’ power goals.

How can Prometheus claim to be ‘zero-carbon’ or ‘carbon-negative’ while using natural gas?
The company achieves its ‘zero-carbon’ goal by pairing its natural gas power generation with carbon capture, utilization, and storage (CCUS) services from partners like Frontier Carbon Solutions, which is intended to sequester the emissions. The ‘carbon-negative’ claim applies to its Casper project with Spiritus, which plans to integrate direct air capture (DAC) technology to remove more carbon from the atmosphere than the facility emits.

What is Prometheus Hyperscale’s ‘hybrid energy model’?
It is a pragmatic strategy designed to provide power to AI data centers with speed-to-market. Instead of waiting for grid upgrades or future clean energy sources, the model uses immediately deployable, behind-the-meter natural gas generation as a ‘bridge’ power source. To align with sustainability goals, this is combined with technologies like carbon capture (CCUS) and battery storage, bypassing grid limitations while working towards a net-zero footprint.

Why is the company focusing its developments in Wyoming and Texas?
These states are chosen for their strategic energy advantages. Wyoming offers abundant natural gas reserves and geology suitable for carbon sequestration, which are essential for the company’s hybrid power model. Texas provides access to established renewable energy portfolios (via partners like ENGIE) and is a water-scarce region, which makes Prometheus’s zero-water cooling technology a key competitive advantage for market entry.

What are the main risks associated with Prometheus Hyperscale’s strategy in 2025?
According to the analysis, the primary risks are tied to execution and reputation. The success of its ‘zero-carbon’ model depends heavily on its partners’ ability to deliver on large-scale carbon capture projects (e.g., Frontier Carbon Solutions). There is also a reputational risk if its ‘green’ branding is challenged due to its reliance on natural gas, and it faces potential regulatory threats that could affect natural gas or CCUS viability.
