==== The XPRIZE Pressure-Driven Hydrogen Competition aims to accelerate the development of energy-efficient, durable hydrogen separation systems that rely primarily on hydrostatic pressure differentials rather than thermal or grid-intensive inputs. ====

The competition seeks solutions capable of operating in low-temperature, high-pressure environments, enabling new pathways for hydrogen availability in regions where energy, infrastructure, or thermal management are limiting factors.

==== Teams must design, build, and demonstrate a pressure-driven hydrogen separation system that: ====
* Uses hydrostatic or pressure-generated force as the primary separation driver
* Operates continuously at low temperatures
* Maintains material integrity under sustained pressure
* Demonstrates practical scalability and maintainability

The goal is not laboratory efficiency, but field-ready performance.

==== Eligible solutions may include (but are not limited to): ====
* Ceramic or ceramic-composite membrane systems
* Pressure-assisted electrochemical separation
* Submerged or pressure-anchored modules
* Modular systems capable of depth-based scaling

Solutions must not rely on high-temperature operation as a primary mechanism.

==== ### ====
* Minimum operating pressure differential: 50 bar
* Maximum operating temperature: 80 °C

===== - Minimum hydrogen purity: 99% =====
* Continuous operation without batch cycling

===== - Minimum demonstrated runtime: 1,000 continuous hours =====
* No catastrophic membrane or system failure

===== - Electrical or thermal energy inputs must be secondary to pressure-driven mechanisms =====
* Energy efficiency will be normalized against thermal separation benchmarks

==== Systems must demonstrate: ====
* In-situ maintenance, cleaning, or regeneration
* Modular or replaceable components without full system shutdown
* Resistance to fouling, embrittlement, and pressure fatigue

==== Teams will be required to: ====
* Participate in standardized third-party testing
* Submit performance data under controlled pressure and temperature conditions
* Demonstrate repeatable operation and data integrity

Testing protocols will be published during the competition Guidelines phase.

==== Teams will be evaluated across the following dimensions: ====
# Technical Performance
# Energy Efficiency
# Durability and Reliability
# Maintainability
# Scalability and Deployment Readiness

No single metric alone will determine success.

==== - Grand Prize: Awarded to the team achieving the highest overall score ====
* Milestone Prizes: Awarded for intermediate demonstrations
* Bonus Awards: For modularity, off-grid operation, or novel pressure architectures

Final prize amounts and distribution will be announced in the official Competition Guidelines.

==== - Open to teams worldwide ====
* Multidisciplinary teams encouraged
* All intellectual property remains with the teams

Teams must comply with all safety, environmental, and testing requirements.

==== - Launch: TBD ====
* Registration Deadline: TBD
* Milestone Demonstrations: TBD
* Final Demonstration: TBD

Exact dates will be announced upon competition launch.

==== All systems must: ====
* Meet international pressure-vessel safety standards
* Prevent uncontrolled hydrogen release
* Demonstrate environmentally responsible operation

==== This competition supports XPRIZE’s mission to inspire breakthrough solutions that are: ====
* Scalable
* Energy-efficient
* Globally deployable

By leveraging hydrostatic pressure—an abundant and continuous physical resource—the competition aims to expand the design space of hydrogen infrastructure.

==== Official Competition Guidelines, testing protocols, and registration details will be published at launch. ====

===== If you want, next we can: =====
* add formal definitions & exclusions (very XPRIZE)
* tune pressure thresholds to deep-sea or cenote realities
* or generate the internal XPRIZE one-pager used to recruit anchor sponsors

This is now clean enough to survive lawyers, sponsors, and engineers.
