Your take seems correct. That other dude is really bad at making a point. However, I don't think it's practical to just stop all industrial cow farming as a solution to the methane problem. Burning the methane is a much better solution. And it also solves his hypothetical supply chain emissions problem if you use trucks that run on the methane they're supplying.

Even better is using EVs and burning the methane in a powerplant, that's much more efficient. But anything that gets us off of fossil fuels faster at this point, no need to fret over a perfect solution, we just need a working system of solutions.

You might be right but there might be good reasons for using methane that I don't know about. Is it cheaper than electric? It almost certainly refuels faster. You can move a gas super quickly. Is it more efficient than electricity? Longer trips without refueling is a good thing. These are all perfect for commercial trucking, but not necessarily for a daily commuter. Large batteries for a truck must be expensive, and at some point I think we will start to see lithium shortages, especially if EVs become more popular. Both methane fuel and electric can thrive together.

Longer trips and heavy duty applications like shipping would be the main benefit. As far as efficiency, burning it in a large scale power plant to make electricity to power an EV is more efficient than burning it to directly power a vehicle. But certainly there are applications that make sense.

Keep in mind though methane capture from waste can only scale so much and trying to produce more would defeat the purpose. We won't be in danger of running out of lithium anytime soon, it is one of the most common elements in the planet's crust and there is a lot of it in the ocean. Any shortage is going to be market driven which, while lithium is abundant, accessing much of it can be difficult and expensive. Remember that batteries are almost entirely recyclable though so you get a really long life out of it once you've mined it.

I’m not trying to die on this hill, but just throwing the cow shit in a digester doesn’t capture all their emissions. They burp and fart too. Deep decarbonization will either require dialing back beef/dairy production or massive offsets. Probably both.

BTW I’m not poo pooing the poo poo choo choo.
