>What you end up with to get there is lots of propane and butane, which is used as a fuel gas, but most of that ends up going up the flare stack because there's so much of it. We won't stop doing this while we still use plastics and fertiliser.

The amount of gas flared globally adds up to little over 1% of global energy production. I know that doesn't sound like much but we're talking like terawatts. It truly is a mind boggling amount of energy that gets wasted because we simply can't get it to users cheap enough.

If only all (or almost all) of it was flared! Methane is a much more potent greenhouse gas than CO2, and unfortunately there is still a lot of it escaping from oil installations unflared (https://www.iea.org/data-and-statistics/charts/potential-emi...).

Or we can't get it clean enough to use as say cooking gas or aerosol propellant.

Stick it in cars, they'll burn any old shite and emit water and carbon dioxide - two terrible greenhouse gases, for sure, but you'll extract useful work from it instead of literally just heating the atmosphere for the fun of it.
