BankableYou watched the verdict.
Here's the whole calculation.
The video gives you the verdict and the two numbers. This is the work behind it — the one-page verdict and the editable techno-economic workbook, so you can put your own power price in and watch the $/kg move. Free.
Verdict: overhyped as the fuel of everything · a real bet as the cleanup of the ~100 Mt/yr we already make — same molecule, two stamps
The verdict
The one-page verdict
- Both stamps, and exactly where the line sits between them
- PEM at ~$5/kg unsubsidized vs the ~$2/kg grey it must displace
- The 39.4 kWh/kg floor — why there is no Moore's law here
- The carbon price that would close the gap on its own
- The ladder: which uses are real demand, which are wishful
The workbook
The editable TEA workbook
- The actual spreadsheet — every yellow cell an input
- Put in your power price and watch $/kg move
- Capacity factor, stack cost, electricity — all live
- The three grid cases: solar+BESS, firm hydro, grid-tied
- Run it in Excel or Google Sheets
Where should I send it?
It's free. I just ask what you're working on — so I know who's out there and what to tear down next.
Here you go. 🎉
Both are yours — open the verdict in your browser, the workbook in Excel or Google Sheets (every yellow cell is an input).
