Consider where that methane / natural gas is coming from. Their homepage says (with the world's most convoluted hyphen-omitting compound adjective, but basically see the last 6 words):
> March 2024: Terraform completes the end to end demo, successfully producing fossil carbon free pipeline grade natural gas from sunlight and air.
If you take carbon from the air, mix in energy from the sun to turn it into a fuel, then burn the fuel (undoing the reaction), where is the pollution?
There's more efficient ways to solve the climate problem than to install ginormous amounts of gas production, like you can run a heat pump instead of creating methane from that energy, but it's a solution that'll please even the old farts (no pun intended)
Not seeing the economics for this ever truly working out, CO2 PPM is very low despite our best efforts and the amount of energy required for separation is substantial.
The economics of taking out a loan or insurance for things you can pay out of pocket also don't work out, but there are apparently entire countries routinely buying groceries and appliances on credit
I'm not saying this is a logical thing to do (note where I wrote "There's more efficient ways to solve the climate problem"), but I've seen humans making less sensible decisions than this one so, who knows, it might actually happen...
