Our HN Launch was number 1 for two days straight 6 years ago, and I wanted to follow up with this huge update - We’ve done it. We now have the technology to revolutionize how energ…

Thanks!

Yes, only inputs are air and electricity. If you have an equipment payback of only a few years, then after that all fuel is close to opex only. Similar to solar itself.

$3.00 / gallon is our v 1.0 (before taxes)

Thanks! Really appreciate the positive comment :)

Thanks for the feedback. Working on the site and hope to have improvements in the next few months with improved tech explanations, clarity, and speed.

Jet fuel energy content is approx. 37 kWh/gallon. At 40% efficiency that's 92.5 kWh. At $0.01/kWh, $92.5 cents per gallon for energy cost. Spot price for jet fuel is approx. $2.00 …

The second important thing is to make the CAPEX really cheap. That's been the core focus for us for the last 2.5 years since demo day and we're looking at really low costs for equi…

One cent per gallon less than the fossil jet fuel spot price - in California (we will use LCFS credits to start)

Project Foghorn was technically successful but couldn't hit the economics. The tech lead on that project is now a scientific advisor for Prometheus - Matt Eisaman

Sorry to all about the drop in website performance. Working on it!

$36/ton is our cost to capture CO2 from the air. For us it is an input to making things, not a product, so we don't need to purify it to 100% pure CO2, just need to capture it into…

Working on it!

In order to make electrofuels cost competitive, you've got to use new utility scale solar, which is now less than $0.02/kWh : https://www.pv-magazine.com/2021/04/08/saudi-arabias-s…

Hi everybody, I'm the founder of Prometheus. Happy to answer any questions!

$36 is the cost of the capital equipment and energy needed to remove the CO2 from the air. Just an internal metric. Not tied to sale prices.

Founder of Prometheus here - stay tuned for a relevant announcement tomorrow!

The CO2 is absorbed in the electrolyte, and that's where we use it in the catalysis process. It is turned into fuel within the electrolyte, then we extract that fuel from it.

Yes, we're actually agnostic on CO2 source. To get to scale we'll need to use CO2 from direct air capture, but we could by the collection from someone else.
