Hydrogen Commons.
Estimate hydrogen output, water demand, fuel-cell recovery and levelized production cost before a community allocates an experimental energy grant.
INSIDE THE REPOSITORY
A complete place to start.
- Electrolyzer mass and energy balance
- Capital recovery and cost sensitivity
- Fuel-cell round-trip estimate
- Exact token contract and pair inspection
- Bounded ERC-20 transfer activity explorer
- Local community funding scenario planner
- Evidence export with SHA-256 verification
- Nine automated checks and GitHub CI
- MIT license, method, architecture and API docs
Run locally
npm test npm start
Open localhost:3000. The technology runs with no API key. Live chain and DNS reads use public providers.
Deploy in your account
Extract the archive and upload its contents to a GitHub repository you control. Import that repository into Vercel, or run npx vercel --prod in the extracted folder. The included configuration sets the output directory and tests.
Return to the Deploy studio to publish your project, token pair and repository on the public build board.

METHOD
What it calculates.
Production = annual electricity / kWh per kg. Capital recovery uses the annuity factor. Recovered electricity uses hydrogen lower heating value of 33.33 kWh/kg times supplied fuel-cell efficiency.
LIMITS
What the evidence means.
Excludes degradation, compression, storage, transport, taxes and incentives. No physical control or financing recommendation.
The funding planner does not transfer tokens or route rewards. Deploying this repository does not imply company endorsement or investment value.
