So each launch is 2x the faeroe islands annual CO2 output
Yes, the comment I replied to is technically right in that there are some tiny countries out there. Or they would be, if the rocket in question would've been a vastly larger rocket that burned a carbon containing fuel. The New Shepard tourist joyride is tiny for a rocket and its exhaust is water vapour.
So hydrogen creation is carbon neutral, didn't know that! /s
Although I doubt it, hydrogen can be produced using renewables.
It's still going to be significantly "greener" than using methane as a propellant, though.
Where did they get all the hydrogen? How did they make the rocket. While it may not emit much carbon on launch day, it will have taken a shit load to produce it.
I was talking about the direct emissions of launching a rocket. The indirect emissions are obviously vastly larger and might as well include everything in the wider economy that enables stuff like this. Just maintaining the necessary industrial capacity is already a huge strain on the planet. That's what I'm after with these comments. The rich fucker joyride is a largely inconsequential yet overtly visible result of a bloated system hiding in plain sight. The aerospace sector as a whole is just the tip of the iceberg of a global industrial society in ecological overshoot.
Hydrogen is usually produced from natural gas with all the carbon being released as CO². So just the direct cost of making the fuel is already terrible.
