Prometheus Hyperscale’s Liquid Cooling Strategy: A 2025 Analysis of Gigawatt-Scale AI Data Centers
Prometheus Hyperscale’s Commercial Projects Validate Liquid Cooling for AI in 2025
Prometheus Hyperscale transitioned from planning large-scale liquid cooling projects in 2024 to executing a multi-state, gigawatt-scale deployment strategy in 2025, validating its technology through commercial projects with major energy and carbon management partners.
- Between 2021 and 2024, the company, then known as Wyoming Hyperscale, focused on a single flagship project in Evanston, Wyoming, expanding its planned capacity from 120 MW to 1 GW and securing a non-binding letter of intent with Oklo for nuclear power. This period established the foundational concept of a massive, sustainably powered data center campus built around its proprietary cooling technology.
- In 2025, the company’s strategy materialized through a series of definitive commercial actions, including solidifying a zero-carbon power solution for its 1.2 GW Evanston campus with PureWest Energy and Frontier Carbon Solutions. It also announced a new 1.5 GW carbon-negative campus in Casper, Wyoming, and a major expansion into Texas with partners ENGIE and Conduit Power to develop sites up to 300 MW each.
- This rapid acceleration from a single conceptual project to a multi-project, multi-state pipeline in 2025 demonstrates increasing market validation for its liquid cooling solution. The diverse partnership portfolio, spanning renewables, low-carbon natural gas with carbon capture, and direct air capture, signals a pragmatic and flexible approach to securing the massive power and sustainability credentials required for AI infrastructure.

Prometheus Hyperscale’s Geographic Strategy: Wyoming and Texas Lead Liquid Cooling Expansion
Prometheus Hyperscale expanded its operational footprint from a singular focus on Wyoming between 2021 and 2024 to a multi-state strategy in 2025, adding Texas as a key growth market to diversify its geographic risk and access different energy ecosystems.
- From 2021 to 2024, all company activity was centered on developing its flagship project in Evanston, Wyoming. This location was chosen to leverage the state’s favorable climate for cooling, access to energy resources, and the founder’s existing land assets.
- In 2025, Prometheus Hyperscale solidified its dominant position in Wyoming by advancing its 1.2 GW Evanston campus and announcing a new 1.5 GW campus in Casper. Concurrently, it launched a significant expansion into Texas, partnering with ENGIE to develop data centers near Dallas.
- This two-state strategy is complementary. Wyoming serves as the company’s foundation, offering a favorable regulatory environment and access to low-carbon natural gas with carbon capture potential. Texas provides access to a large, competitive renewable energy market and major connectivity hubs, demonstrating a deliberate plan to operate and scale within diverse energy and economic landscapes.
Prometheus Hyperscale’s Liquid Cooling Moves from Concept to Commercial Scale
In 2025, Prometheus Hyperscale’s proprietary liquid cooling technology advanced from a conceptual framework in 2024 to the brink of commercial-scale deployment, validated by gigawatt-scale project commitments and strategic partnerships for integrated energy solutions.
- During the 2021-2024 period, the company’s technology was primarily defined by its ambitious performance claims, including up to 50% reduction in facility energy consumption and zero water use for cooling. Its viability was theoretical, supported by plans for the Evanston project and a non-binding agreement with Oklo.
- The year 2025 marked a turn toward tangible application, with the technology specified as the core of both the 1.2 GW Evanston and 1.5 GW Casper projects. The system was described in greater detail as a “proprietary, non-consumptive, aquifer-based water-cooling system,” also referred to as a geothermal technology, and its technical leadership was reinforced by the appointment of liquid cooling expert John Gross as CTO.
- The technology’s maturation is further validated by the ecosystem being built around it. A pilot with XL Batteries to deploy a 333 kW organic flow battery demonstrates a move toward integrated energy resilience. The commitment of major energy partners like ENGIE and PureWest to gigawatt-scale projects built around this cooling system serves as strong external validation from the energy industry.
SWOT Analysis: Prometheus Hyperscale’s Liquid Cooling Position in 2025
Table: Strategic Analysis of Prometheus Hyperscale’s Market Position
| SWOT Category | 2021 – 2024 | 2025 | What Changed / Resolved / Validated |
|---|---|---|---|
| Strengths | Proprietary liquid cooling concept with strong efficiency claims. Land assets for a flagship project in Wyoming. | A confirmed multi-gigawatt project pipeline (1.2 GW Evanston, 1.5 GW Casper). Strategic partnerships across energy (ENGIE, PureWest), technology (XL Batteries), and leadership (Bernard Looney). | The company’s strategy evolved from a single-project concept to a validated, multi-state plan backed by a strong partner ecosystem and experienced leadership, adding significant credibility. |
| Weaknesses | Unproven technology at commercial scale. Dependence on a single, large-scale project and non-binding agreements (e.g., Oklo LOI). | High capital intensity requiring significant external funding. Execution risk associated with developing multiple gigawatt-scale projects simultaneously. Reliance on partners’ emerging technologies (SMRs, CCS). | The scale of ambition has amplified the execution and financial risk. The core technology remains to be proven in a live, gigawatt-scale environment, shifting the key challenge from concept to execution. |
| Opportunities | Growing demand for data centers driven by cloud computing and big data. | Explosive demand for high-density AI infrastructure that traditional air cooling cannot support. Intense pressure on the industry to address its massive energy and water consumption. | The market’s need for Prometheus Hyperscale’s specific solution, high-density and sustainable cooling, became acute due to the AI boom, dramatically expanding its total addressable market. |
| Threats | General competition from established data center developers. | Potential delays in partner technology deployment (Oklo’s SMRs, Frontier’s CCS). Grid interconnection delays in key markets like Texas. Capital market fluctuations impacting project financing. | Threats became more specific, tied directly to the execution of its complex, multi-partner strategy rather than general market competition. Success is now contingent on its partners’ parallel success. |
Future Outlook: Prometheus Hyperscale’s Execution on Gigawatt Projects is Key for 2026
The primary focus for Prometheus Hyperscale in the year ahead will be the physical execution of its initial data center projects in Wyoming and Texas, as successful construction and operation are critical to validating its integrated technology and energy model at commercial scale.
- The first Texas data center sites, co-located with ENGIE’s renewable assets, are scheduled to go live in 2026. Progress on their construction will be the first critical test of the company’s ability to execute its model outside its home state of Wyoming.
- Development of the 1.5 GW carbon-negative campus in Casper, Wyoming, will be closely monitored. The successful integration of direct air capture technology from partner Spiritus would set a new benchmark for sustainable digital infrastructure and provide a powerful proof point for the company’s environmental claims.
- The planned 2027 installation of the 333 kW demonstration battery from XL Batteries will be a key milestone. It will validate the use of non-lithium, long-duration energy storage as a viable solution for providing resilient power to AI data centers.
- Future announcements detailing the locations and energy strategies for the company’s pipeline of four additional data center sites will indicate the pace of its expansion and the market’s confidence in its technology and business model.
