Subsurface biotechnology

Turning depleted
reservoirs into hydrogen
production hubs

We engineer microbes that ferment residual hydrocarbons underground — using existing oilfield infrastructure to produce clean hydrogen at scale.

01 — Inject

Microbes + nitrogen

Injected into depleted reservoirs via existing well infrastructure. No new wells required.

02 — Ferment

Subsurface conversion

Bacteria convert residual hydrocarbons and N₂ into H₂ in oxygen-free, high-pressure conditions.

03 — Recover

Hydrogen to surface

Gas migrates toward collection points and is captured through standard production infrastructure.

Sixty years of oilfield biotech — redirected

Since the 1960s, oil companies have known that certain bacteria thrive deep underground. By injecting microbes into wells and feeding them simple sugars, operators converted nutrients into CO₂ and H₂ — gases that unlocked trapped hydrocarbons and pioneered microbial enhanced oil recovery.

We build on that foundation, redirecting the same biochemistry toward a different output: hydrogen, not oil.

Nature's cleanup crew, given a new job

Microbes have long been used to remediate oil spills and process paraffins in wells — digesting hydrocarbons through fermentation. We apply the same principle underground, engineering the output toward hydrogen rather than alcohols or organic acids.

In the oxygen-free environments of depleted reservoirs, naturally occurring or engineered bacteria ferment residual hydrocarbons into hydrogen gas — transforming stranded carbon into a renewable energy source.

Harnessing the most abundant gas in the atmosphere

Certain microbes convert N₂ directly into ammonia (NH₃), releasing hydrogen in the process. This reaction — driven by the nitrogenase enzyme — operates even under the oxygen-free, high-pressure conditions found in oil reservoirs, making it an ideal biological pathway for in-situ hydrogen generation.

Billions of dollars of injection capacity, already in place

Oil and gas operators already inject tons of nitrogen per day into depleted reservoirs to maintain pressure. We pair this existing infrastructure with microbial biotechnology — turning nitrogen from a cushion gas into a substrate for hydrogen production.

No new injection wells. No new compressor stations. Existing nitrogen injection programs become a dual-use platform for pressure maintenance and clean hydrogen generation.
