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…”

Thiel: Synthetic fuels require $1/kg hydrogen and $100–$200/ton CO2
“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 10…”

Thiel: Small-scale green Haber-Bosch struggles with synthesis loop scaling
“So, so at the end of the day, if you're trying to scale down a Greenhaber Bosch plant, maybe maybe you'll be able to do okay on the core parts of the electrolysis side of the equation here, the cells and stuff and so forth. But the ammonia synthesis loop and t…”

Thiel: $100/ton DAC CO2 adds $6/MMBtu to synthetic methane costs
“The, again, sort of best case from the chemistry is something like 2.75 kilograms of CO₂ per kilogram of methane. So thinking back on a, on an MMBTU basis, you know, if you want to Get the good sort of CO₂ from the air, and we hit all our hopes and targets of …”

Thiel: Hydrogen Cost Is Overwhelmingly Dominant Cost Driver for Synthetic Fuels
“If you want to make a synthetic Fuel. If it's going to be a hydrocarbon, you do need a source of carbon, and the source of that CO₂, carbon CO₂, matters from a carbon economic perspective. But from a cost perspective, The thing that matters is number one, the …”

Thiel: Single-pass conversion gains do not significantly improve green methanol economics
“If you get A better conversion of CO two and hydrogen to methanol on a single pass. It just really doesn't move the overall economics in a huge way because again, back to a previous point, CO two and hydrogen are the big cost drivers in that system.”

Thiel: Early techno-economic models should focus on error bars, not detailed design
“It's better or it can be helpful just to put error bars and understand the sensitivities on things earlier on and go down the deeper, more detailed design rabbit holes when the higher level stuff is fixed.”

Thiel: Standard synthetic methanation achieves approximately 50% total efficiency
“If you used something like that and did this kind of fairly standard methanation process, the total efficiency of the process kind of comes in around 50% ballpark, right? And about half of those losses of the 50% of the energy that you lose are in the electrol…”
