A philanthropic fund connecting industry, government, and academia to responsibly and rapidly scale geologic hydrogen by the 2030s.

A natural gas. Without the carbon.

Generation pathways

The Earth makes hydrogen in more than 30 ways.

Different geologies generate hydrogen under different conditions — that is why the potential spans every continent.

WATER IN IRON-RICH ROCK HYDROGEN OUT U Th K WATER IN RADIOACTIVE ROCK HYDROGEN OUT

We focus on two of them.

Serpentinization

Water reacts with iron-rich rock deep underground, oxidizing the iron and releasing hydrogen gas.

Radiolysis

Radioactive elements in rocks—such as uranium, thorium, and potassium—emit alpha, beta, and gamma radiation that breaks apart underground water (H₂O) molecules.

Generation + Recovery

NATURAL ACCUMULATION

The Earth's own timeline.

Infiltrating water contacts rock at depth. In iron-rich rock, water oxidizes ferrous iron and forms hydrogen (e.g., serpentinization). In older basement rock, radiation from uranium, thorium, and potassium breaks water molecules apart (i.e., radiolysis). H₂ from these processes can migrate via fracture networks and accumulate beneath a caprock seal, over geologic time.

ENGINEERED RECOVERY

Natural processes accelerated.

Injecting a water-based solution into iron-rich rock may accelerate the same reaction on demand — effectively turning suitable formations into hydrogen generators. The first commercial pilots are underway in Quebec, building on prior research in the laboratory.

Heavy industry

Low-cost H₂ can directly reduce iron ore in steel production and provide zero-emissions, high-temperature heat in industrial processes where electrification is impractical.
