Subterra

Why Hydrogen?

Natural hydrogen is a clean, renewable energy source generated continuously by geological processes in the Earth’s crust. Unlike manufactured hydrogen, it requires no carbon-intensive production and can be tapped directly from subsurface reservoirs. Unlocking natural hydrogen could transform the global energy landscape—delivering low-cost, low-emission energy at scale.

Why Microbiology?

The subsurface is alive. Microbial life thrives kilometers beneath the surface and plays an active role in the chemistry and behavior of underground reservoirs. In hydrogen storage and exploration, these invisible ecosystems can consume hydrogen, alter reservoir properties, produce corrosive byproducts like hydrogen sulfide, and jeopardize caprock integrity. Ignoring microbiology means ignoring a key risk factor that can compromise safety, reduce recoverable hydrogen, and inflate costs.

Why Subterra?

Subterra is the first company to tackle the hidden biological risks in subsurface energy systems. We combine microbiology, geoscience, and AI to help clients safely explore and store hydrogen, CO₂, and natural gas. Our software, Biosphera, models the underground biosphere to predict microbial behavior, assess risks, and support decision-making. With Subterra, you don’t just see the geology—you understand the life within it.

Looking ahead

Subterra is building the future of subsurface intelligence. As hydrogen, carbon storage, and natural gas reshape the global energy landscape, understanding the biological dimension will be essential. Our vision is to make microbiology a standard part of subsurface operations—reducing risk, improving efficiency, and enabling cleaner, safer energy systems. By unlocking the deep biosphere, we’re opening new frontiers for sustainable energy.

Our solution: Biosphera

Biopshera is Subterra’s GeoBiological Software to de-risk industry investments in Natural Hydrogen prospecting and Underground Hydrogen storage

Biosphera is Subterra’s revolutionary web application—designed to bring the invisible world of subsurface microbiology into the hands of energy professionals. Built on cutting-edge science and proprietary data, Biosphera allows clients to assess the presence and impact of microbial life in geological reservoirs. It models the expected size, diversity, and activity of microbial communities, simulates hydrogen consumption under real-world conditions, and calculates risk indexes to guide + exploration, storage, and operational decisions. Integrated with leading geochemical and geological software, and powered by AI-assisted analysis, Biosphera turns complex biological data into clear, actionable insights. Whether you're developing a natural hydrogen prospect, planning underground hydrogen storage, or managing a carbon capture or gas field project, Biosphera helps you anticipate microbial risks before they become costly problems—transforming microbiology from a blind spot into a strategic advantage.
