Jeff Bezos’ Blue Origin rocket tests in Texas are emitting so much methane you can see it from space::So much you can see it from the ISS in space.

I dislike Blue Origin as much as the next guy, but IMO the article (or at least the headline) distracts from the real problem here (the fossil fuel industry):

An air permit application filed with the TCEQ in January 2020 said the company expected to routinely dump LNG into the air to the tune of 3.4 million cubic feet a year, which would work out to more than 60 tons of methane.

Of course, Blue Origin’s emissions pale in comparison with those from its suppliers in the natural gas industry. Wells and pipelines in the Permian Basin, a huge oilfield near the rocket site, are thought to give off some 2.7 million tons of methane a year

The state air regulator, the Texas Commission on Environmental Quality, doesn’t impose limits on methane emissions or require disclosure of releases.

Well there’s your problem.

So we have hydrogen as rocket fuel that does not produce greenhouse gasses when burned and they decide to develop methane as a fuel source instead! Why!?!

Hydrogen requires energy to get, which practically requires fuel to be burned. Sure, you could use green energy, but you could also still build the green energy and just offset other energy demand elsewhere, which would take dirty energy off the grid.

This isn’t mentioning all the issues with hydrogen, the largest probably being that it does not like being contained. It’s literally just a proton and electron. It’s tiny, so really nothing can contain it perfectly.

Hydrogen itself is a strong greenhouse gas and leaks from everything, so it wouldn’t necessarily be better.

Each fuel has it’s own use case, but in the case of reusable rockets…

Hydrogen is harder to store, it leaks out of everything. Methane can sit in a tank for a long time. Holding a tank of methane so you can relight a rocket and land after being in space for a long time is a big advantage, and keeps you from having to throw away everything each flight.

Methane is easier to store and doesn’t embrittle the pressure vessel.
