Process input
Core Technology
Built by a team with decades of nuclear-sector engineering experience.
A controlled reaction between recycled aluminum and water produces heat, hydrogen, and alumina in a single process. Factory-built in standard modules; typical commissioning takes 12–24 months depending on site, configuration and approvals.
How it works
Three outputs.
One controlled reaction.
Inputs
Recycled aluminum
Graded metal feedstock
Reaction
Aluminum-Water Reactor
A controlled exothermic chemical process.
Outputs
Thermal energy & power
Heat recovered for direct use or conversion.
Hydrogen
Gas produced alongside the thermal output.
Alumina trihydrate
Solid material recovered for polishing.
Feedstock in
The reactor runs on recycled and scrap aluminum, graded to specification. Aluminum is abundant, stable at ambient conditions, and supported by mature recycling and logistics networks.
The reaction
Inside the reactor barrel, aluminum reacts with water under controlled temperature and pressure. Nothing burns. Output is governed to follow site demand.
Three outputs
A single reaction yields three streams: thermal energy, hydrogen gas, and alumina trihydrate. They are products of one chemical process, captured in parallel.
Power conversion
Each module provides 1 MW of heat and 1 MW of hydrogen energy, convertible to on-site electricity through fuel cells or generators. Hydrogen may also be captured for delivery under offtake.
Alumina recovery
Alumina trihydrate is captured in solid form rather than vented or landfilled. It leaves the reactor as feedstock for the polishing line.
Core technology
Four systems.
One modular platform.
Barrel reactorarchitecture
The core reaction vessel, and the unit on which all capacity scaling is based.
Reactioncontrol
Controls the reaction rate so system output can follow the site's load.
Thermal recoveryand power conversion
Captures reaction heat for steam or conversion to on-site electricity through fuel cells or generators. Electrical output remains pending validation.
Alumina recoveryand polishing
Captures the alumina stream for upgrading. Engineered to target specification. Samples available for customer qualification.
Patent details pending final disclosure review.
System overview
One barrel.
Two megawatts.
One barrel is one 2MW reactor module, factory-built and containerized to a standard footprint. Capacity is added by adding modules rather than engineering to a fixed site load. Start at the capacity required today and add units as demand proves out. A complete installation pairs reactor modules with feedstock storage, hydrogen handling, and alumina collection.

Safety and licensing
What “reactor” means here.
No fissile material
The Aluminum-Water Reactor contains no fissile material and no radiological inventory. It is not subject to nuclear licensing. The name describes a controlled chemical reaction.
Engineering experience
Built by a team with decades of nuclear-sector engineering experience. This does not imply nuclear-system certification.
Hydrogen handling
Hydrogen is produced, stored, and handled in purpose-designed containment systems. Applicable codes remain subject to final disclosure review.
Permitting
Deployment requires pressure vessel certification, electrical inspection, and hydrogen storage permitting. No nuclear licensing pathway applies.
The second product line
From byproduct to targeted material grades.
The aluminum-water reaction produces alumina trihydrate. GH Power's proprietary polishing line is engineered to target alumina oxide specifications for high-technology manufacturing. Samples are available for customer qualification.
Recovery
Alumina trihydrate captured from the reactor stream.
Purification
Impurities removed to target specification.
Calcination
Conversion to alumina oxide.
Sizing
Particle size and morphology controlled to customer specification.
