System Generates Real-World Data to Accelerate Commercial Deployment
Titusville, FL, February 11, 2026 — GenH2 Corp, a Path2 Hydrogen Company (FRA: PTHH.DE) and a leader in liquid hydrogen (LH₂) infrastructure solutions, announced the successful commissioning and validation of its Cryostat CS900 Liquid Hydrogen (LH₂) Simulation Test Platform, marking a significant milestone in advancing deployable, zero-loss liquid hydrogen infrastructure.
The Cryostat CS900 LH₂ Simulation Test Platform integrates hydrogen liquefaction, Controlled Storage and transfer within a unified LH₂ infrastructure environment. The platform is capable of generating real-world performance and behavior data for materials, systems, and processes essential to equipment supporting liquid hydrogen infrastructure solutions.
Since November 2024, GenH2 has been utilizing the test platform to liquefy, store and transfer, hydrogen for use in various performance scenarios, all without loss, generating first-of-its-kind data. The valuable insight gained from these capabilities provides a unique advantage in developing the next generation of technology that will serve as the backbone for a clean energy infrastructure.
“The CS900 delivers the real-world data to help mitigate technical risk and allow liquid hydrogen to function as a practical energy carrier for widespread commercial use”, said James E. Fesmire, Chief Architect and Co-Founder of GenH2. “This platform provides unprecedented insight that allows us to accelerate innovation and establish new standards for liquefaction, storage and transfer of hydrogen without loss.”
The Cryostat CS900 platform is based on technology pioneered by Fesmire during his career at NASA’s Kennedy Space Center, where he developed advanced engineering systems to evaluate thermal performance under extreme cryogenic conditions. The CS900 replicates real-world operating conditions to evaluate thermal behavior, storage stability, and controlled liquid hydrogen transfer in relevant conditions.
Data generated on the platform is applied directly to the engineering design of GenH2’s liquefaction, Controlled Storage, and zero-loss transfer products, accelerating the deployment of standardized LH₂ infrastructure solutions while reducing technical and commercial risk. The platform also supports key industry initiatives, including projects with companies such as Shell (Department of Energy funded) and other LH₂ pipeline technology component manufacturers.
Examples of testing and analysis that have been conducted on the Cryostat CS900 Platform include performance and behavior of:
- Hydrogen liquefaction, re-liquefaction and condensation
- Ground-based storage tanks and onboard vehicle tanks
- Heat lift technology and sub-cooling of liquid hydrogen
- Zero-loss controlled storage and transfer components
- Instrumentation, sensing, and feedback technologies
- Validation of design parameters, analytical models and system safety
This milestone is the culmination of decades of innovation in the practical use of LH₂. Going forward, the CS900 platform will continue to be a critical component in product development, enabling GenH2 to design and develop liquid hydrogen technology that is unparallelled in the industry.
