==== Hydrogen is a foundational element for clean energy, industrial processes, and advanced digital infrastructure. However, existing hydrogen separation and production technologies are constrained by high energy consumption, thermal stress, material degradation, and dependence on centralized electrical grids. ====

This XPRIZE Challenge seeks to catalyze a new class of hydrogen systems that leverage hydrostatic pressure as a primary driving force, reducing reliance on heat and grid-intensive energy inputs while improving durability, maintainability, and system longevity.

==== Teams are invited to design, build, and demonstrate a pressure-driven hydrogen separation system that uses hydrostatic pressure differentials—natural or engineered—to separate hydrogen through ceramic or ceramic-composite membranes under low-temperature conditions. ====

Solutions must demonstrate continuous, stable operation and be designed for real-world deployment rather than laboratory optimization.

==== ### ====
* Hydrostatic pressure (≥50 bar) must be the dominant driver of hydrogen transport or separation.
* Operating temperature must remain below 80 °C.

===== - Membranes must be ceramic or ceramic-composite based. =====
* Designs must prioritize mechanical robustness, low brittleness, and chemical stability.
* Use of precious metals is discouraged.

===== - Systems must operate continuously for a minimum of 1,000 hours under sustained pressure differentials. =====
* Structural integrity must be maintained without catastrophic failure or performance collapse.

===== - Systems must demonstrate in-situ cleaning, regeneration, or pressure-based recovery without membrane replacement. =====
* Maintenance procedures must be practical and repeatable.

==== Teams will be evaluated on: ====
* Hydrogen selectivity (≥99%)
* Sustained hydrogen flux over time
* Energy efficiency relative to thermal ceramic membrane benchmarks
* Stability under continuous operation
* System simplicity and scalability

Additional recognition will be given for:
* Modular architectures
* Depth-scalable performance
* Operation in off-grid or submerged environments

==== By shifting the engineering paradigm from thermal intensity to pressure leverage, this challenge aims to unlock: ====
* Lower-energy hydrogen separation pathways
* Durable systems suitable for remote and infrastructure-constrained regions
* New approaches to long-duration industrial and computational infrastructure
* Reduced lifecycle costs and improved resilience

This challenge aligns with XPRIZE’s mission to advance breakthrough solutions that are scalable, sustainable, and globally relevant.

==== XPRIZE rewards innovations that: ====
* Reframe existing constraints
* Deliver measurable, real-world performance
* Enable long-term impact rather than short-term optimization

The Pressure-Driven Hydrogen Challenge invites teams to rethink how fundamental physical forces—such as gravity and pressure—can be engineered into practical, high-impact solutions.

==== Hydrostatic pressure is continuous, abundant, and globally available. ====
This challenge asks whether it can be transformed into a reliable industrial asset.

If you want next, I can:
* align this exactly with prior XPRIZE call formats
* draft a technical rulebook appendix
* or create a one-slide executive summary for sponsors

No spectacle.
Just engineering.
