About GaugeH2
GaugeH2 is the hydrogen project intelligence platform — built for the engineers, analysts, and investors who need rigorous numbers, not marketing slides.
Our Mission
To make green hydrogen economics transparent, verifiable, and accessible to every professional working in the energy transition.
Hydrogen investment decisions often rest on spreadsheets that are hard to audit. We built GaugeH2 to change that: a shared platform with open methodology, tamper-evident calculations, and benchmark data from real projects, each with its source.
What We Do
GaugeH2 provides three core capabilities:
- LCOH Calculator — a full Discounted Cash Flow model for Levelized Cost of Hydrogen, covering PEM, Alkaline, SOEC, and AEM electrolysis. Every calculation is versioned and hashed, so a third party can check it is untouched and reproduce it.
- Project Intelligence — tracking and Readiness Score assessment for green hydrogen projects worldwide, based on public data from the IEA Hydrogen Projects Database and project disclosures, each with its source.
- Benchmarks — what our model gives for the projects announced in the public catalogue, under declared assumptions. They include no user calculations and are not market prices.
Why We Exist
Green hydrogen has the potential to decarbonize industries that cannot be electrified directly — steel, ammonia, shipping, aviation. But realizing that potential requires capital, and capital requires confidence in the numbers.
Too often, project economics are obscured by proprietary models, inconsistent assumptions, and unverifiable claims. GaugeH2 was built on a single conviction: better data leads to better projects, faster.
Our methodology is fully documented, our model versions are public, and every calculation can be reproduced by a third party. We believe transparency is not just good practice — it is a prerequisite for the energy transition to work.
Data Sources
Project data is sourced from the IEA Hydrogen Projects Database (CC BY 4.0) and public project disclosures. Technology parameters are platform defaults for a first estimate: the PEM and alkaline CAPEX are installed-system figures from the IEA Global Hydrogen Review 2025, the other parameters are platform assumptions, and every report marks each one as a platform default. See our full Methodology for details.
News that leads us to new projects is found with the GDELT Project. A news item is only a lead: before a project enters the catalog, its data is checked against the developer’s own announcement or an official register.
