Next-generation geothermal power

Reliable, low-carbon electricity is essential for energy security and decarbonisation. Next-generation geothermal projects are emerging across the U.S., delivering continuous baseload power with advanced drilling and surface power generation. One project is transitioning from concept to commercial reality, demonstrating how engineered innovation can make geothermal power a major force in clean energy.

This large-scale project demonstrates that next-generation geothermal can advance from pilot to full-scale, repeatable commercial deployment. By consistently delivering grid-scale electricity, it positions geothermal as foundational infrastructure for the clean energy transition and reinforces confidence in its scalability.

Engineering reliability into continuous power

Geothermal environments push rotating equipment and infrastructure to their limits. High temperatures and variable duty cycles demand that every system and component perform reliably around the clock, meeting strict uptime and maintenance targets.

To support this project, John Crane will provide a suite of sealing technologies for high-performance turbomachinery, along with dynamic testing services. These solutions support reliability and safety where uptime is critical.

The scope includes:

• Wet mechanical seals engineered for challenging process conditions
• Separation mechanical seals that protect critical equipment interfaces
• Couplings designed for efficient, reliable power transmission
• Dynamic testing services to validate performance under simulated operating conditions prior to full commercial deployment

Together, these technologies help ensure surface power generation systems operate as intended. They help reduce the risk of unplanned interruptions and support stable, continuous energy production.

Unlocking geothermal at scale

Unlike conventional geothermal systems that rely on naturally permeable reservoirs, next-generation geothermal applies advanced horizontal drilling and subsurface monitoring techniques. This approach accesses deeper, hotter rock formations. These techniques enable the development of productive geothermal systems in locations previously considered uneconomic. They expand the geographic potential of geothermal power. Continuous monitoring during drilling and operation helps optimise well placement, improve reservoir performance and support predictable, long-term energy production.

Geothermal energy delivers steady baseload power, very low lifecycle emissions, and extended asset longevity. This project leverages advanced drilling and state-of-the-art surface technology. It demonstrates how previously unreachable resources can become dependable electricity sources for decarbonisation and increased resilience.

Across the U.S., new geothermal projects reflect rising confidence in the technology’s commercial potential. Each deployment adds real-world operating data, strengthens utility confidence and helps establish geothermal as a commercially viable contributor to the U.S. energy mix.

Accessing deeper geothermal resources with different available energy levels (from low to high enthalpy applications) also introduces higher temperatures, increased pressures, different working fluids and more demanding surface conditions. Turbomachinery, sealing systems and rotating equipment must withstand continuous thermal loads while maintaining tight tolerances and operational stability. Surface infrastructure becomes a critical enabler of commercial success.

The key outcomes this development aims to support include:

• Expanded access to low-carbon electricity
• Improved energy security through continuous baseload generation
• Real-world demonstration of next-generation geothermal technologies

The sealing technologies and testing services provided for this project are designed to support:

• Stable, efficient operation of turbomachinery
• Protection of critical equipment interfaces
• Validation of performance before full-scale operation
• Long-term reliability in continuous service

Dedicated engineering and project management teams will oversee delivery. They will ensure rigorous testing, execution excellence and sustained operational performance. This level of technical oversight is essential to bringing advanced energy projects online safely and reliably.

Engineering expertise accelerating the energy transition

Specialised engineering is core to cleaner, more resilient energy. By applying proven flow control and rotating equipment expertise, this project demonstrates how trusted industrial capabilities can turn next-generation clean energy concepts into commercial realities.

This development also aligns with broader efforts to advance key energy transition markets, including geothermal, hydrogen, carbon capture and sustainable power generation. These sectors demand equipment that performs reliably in challenging environments while meeting evolving sustainability expectations.

A collaborative model for next-generation energy projects

Delivering advanced geothermal systems requires close coordination across disciplines. This ranges from subsurface development to surface equipment integration and long-term operational planning. Dedicated engineering and project management teams guide execution. They ensure solutions meet performance expectations while maintaining a strong focus on safety and reliability.

Dynamic testing services—checking equipment while it operates before full use—strengthen this approach by validating machinery under simulated operating conditions, enabling a smooth transition from commissioning to stable operation.

Advancing clean, reliable power through engineering

This project is a milestone in providing low-carbon power for the U.S. By combining innovative drilling, surface power and reliable turbomachinery, it demonstrates that advanced engineering can unlock geothermal resources and reinforce energy security.

By supplying a comprehensive suite of sealing technologies for high-performance turbomachinery, along with dynamic testing services, John Crane supports reliable, safe operation in technically demanding geothermal environments. In these environments, performance, precision and uptime are essential.
