Prometheus Hyperscale, Spiritus, and Casper Carbon Capture partner to build carbon-negative data halls and energy infrastructure in Wyoming (U.S.)

10/8/2025

Prometheus Hyperscale, Spiritus, and Casper Carbon Capture have announced a strategic partnership to develop a pioneering carbon-negative digital infrastructure campus in Wyoming. The project is expected to include a minimum of $500 MM in initial investment and deliver up to 1.5 gigawatt (GW) of IT-ready capacity over multiple phases, making it one of the largest AI-focused infrastructure developments in the Rocky Mountain region. First IT-ready power is targeted for 2026.

Project overview and strategic vision. The Casper project and strategic partnership is designed to meet accelerating demand for AI compute capacity while embedding carbon removal into the project's core. It unifies three pillars:

  • Data Infrastructure — Prometheus Hyperscale will design and finance high-density compute halls using proprietary aquifer, non-consumptive water-cooling systems to maximize energy efficiency.
  • Energy Systems — Spiritus builds on its work in Wyoming with its new platform Orchard Power, which will deliver 1.5 GW of onsite firm power fueled by natural gas, integrated point-source and direct air capture (DAC) to drive fast, affordable, carbon-negative operations.
  • Carbon Sequestration — Casper Carbon Capture will provide land, rights-of-way, and access to permitted CO₂ sequestration wells in Natrona and Converse Counties, ensuring permanent storage of captured emissions.

Prometheus Hyperscale: Proven track record in Wyoming and Texas. This new data center development builds on Prometheus' initiatives in Wyoming and Texas:

  • Evanston, Wyoming Flagship Project: Scaling toward 1 GW+ IT capacity, with partnerships for low-carbon natural gas, nuclear SMR power, and organic flow battery systems.
  • Texas Projects: Partnerships with ENGIE North America and Conduit Power to co-locate AI data centers alongside renewable and hybrid power systems across the I-35 corridor.

The Casper project stands as one of the most significant digital infrastructure initiatives in Wyoming's history, with a multi-phase buildout planned to deliver up to 1.5 GW of IT load. This development is expected to generate hundreds of construction jobs during the building phase and create dozens of long-term technical positions upon completion. The project will also expand the tax base by generating new property, utility, and infrastructure revenues for Natrona and Converse Counties. In addition, it will position Wyoming as a national leader in AI infrastructure, power, and carbon removal technologies, reinforcing the state's reputation for energy and carbon leadership.

Trenton Thornock, Founder and CEO of Prometheus Hyperscale, commented: "We're excited to develop another project in Wyoming. The Casper project and this partnership with Spiritus and Casper Carbon Capture further enables Prometheus' vision of developing the future of digital infrastructure sustainably."

Charles Cadieu, CEO and co-founder of Spiritus commented: "AI companies can't wait years for power. By partnering with Prometheus, we're delivering firm capacity to meet the urgency the market demands. Orchard Power gives tenants reliable, affordable, carbon negative electricity at hyperscale, when and where it's needed."

Jess Foshee, CEO and co-founder of Casper Carbon Capture, commented: "By bringing world-class partners together, we're showing that Wyoming's land, resources, and people can power the future while we keep our commitment to stewardship and community at the center."
