Independent certification · Europe
The subsurface holds the energy transition. We make it bankable.
SubsurfaceCert turns raw geological data into independent, probabilistic resource certificates for CO₂ storage, geothermal, and natural hydrogen — the verification investors and regulators need before capital moves.

The problem
Capital is ready. Verification is the bottleneck.
Europe must move billions into subsurface energy projects to hit its climate targets. But banks and insurers will not fund what they cannot independently verify — and today, no standard method exists across CO₂ storage, geothermal, and hydrogen.

“Without a common certification language, every project is assessed from scratch. That friction is measured in months and millions.”
The platform
From raw geology to a certificate capital can trust.
Our platform constructs mathematical reservoir models, calibrates them against real geological data, and generates probabilistic resource estimates with P10/P50/P90 confidence levels — the language financial institutions require.
Built on a century of reservoir science — delivered as a system.
One rigorous method, applied across three sectors. Select a sector to see how the same certification architecture adapts to each subsurface resource.
Capacity, containment, and injectivity verified from permit through to operation — the assurance lenders and regulators require before backing a storage project.

The opportunity
A European market defined by three growing sectors.
Demand for independent subsurface certification is being created across Europe by regulatory mandates and a wave of energy-transition projects — spanning carbon storage, geothermal, and natural hydrogen.
Regulatory pullEU mandates make independent verification a condition of funding.
First-mover timingNo incumbent standard spans all three subsurface sectors.
Recurring revenueMonitoring and recertification compound value beyond first sale.
About us
Operators and engineers who know this ground.
SubsurfaceCert is built by three founders whose careers span the commercial, technical, and operational sides of subsurface energy. The team that sets this standard will help define the market around it.
