“And you know that, you know, for a fuel, if you want to get anywhere close to economically competitive, you know, subsidies decide you have to have hydrogen that's going to be on the order of a dollar per kilogram, and you have to have CO two that's in that 100 to 200 dollar per ton range, and that CO two has to be CO two that's coming, as you say, from the atmosphere or from a biogenic source.”

Thiel: New grid storage must hit $100-$150/kWh to beat 2030s LFP
“So I think that the numbers that we've landed on in, in our work are sort of in the hundred to 150 dollars per kilowatt hour total installed system cost. If you can see a path, a pretty clear path to those numbers, with your system, then you probably have a pr…”
Thiel: Even at $1/kg hydrogen, synthetic methane feedstock costs $10/MMBtu
“In the best case, you need something like half a kilo of hydrogen per kilo of methane. And so if we looked into a, to a wonderful version of the future where we, Get to the kind of magic one dollar per kilogram hydrogen mark that, you know, is, is on the DOE's…”
