methane

“So the absolute first thing you have to do, which is basically a no regrets option because it's actually ends up being relatively low cost is. Become a methane emissions hawk and go after those upstream emissions as aggressively as humanly possible.”

“What we actually do is we mix the plastic in with organic waste and put that in the landfill, and because there's all this plastic mixed in with the organic waste doesn't have any access to oxygen, and so it decomposes anaerobically and emits all of its carbon…”

“In the U.S., that's like two and a half percent average leakage rates. That can, over a 20 or 30 year lifetime, that can double the climate impact of your fossil fuel inputs, which is, so if we don't talk about the upstream leakage and we don't account for tha…”

“Whenever we compare things on a GWP 100 basis between methane and CO₂, what we are fundamentally doing is actually making a trade-off, one that we're not always conscious of, between near-term warming and long-term warming.”

“90% of methane ends up being what's called oxidized by something called the hydroxyl radical in the atmosphere.”

“And so the climate models are fundamentally depending on us Dramatically cutting methane by, you know, every model's different, but 70, 80% by 20 50, or by 2100.”

“So when you cut CO₂, you stop warming it, stop warming the atmosphere even more than it already is. When you cut methane, you eventually, over about a decadal time span, start actually bringing that warming down. It's a fundamentally different dynamic.”

“First, over a 20 year period, rather than a hundred year period, methane traps 84 times more heat than CO₂.”

“According to the global methane pledge, if you want to measure it by dollars, only two percent of global total climate financing goes toward methane today.”

“The most ready reductions in methane do come from oil and gas. We have ready solutions there, and that is a place where we can start to bend the curve of methane”

“Methane, for example, is currently causing half a degree of warming. It's about 30% of current gross, ah, warming. Methane has an atmospheric lifetime of about 12 years.”

“And second, depending on how you define it, methane has contributed to up to around half, nearly 50% of net warming since the pre-industrial era today.”

“The safety aspects of leaking hydrogen, because the properties of leaking hydrogen is much more dangerous than leaking, Methane. Partly because it's harder to detect. So, So that's one reason why systems are likely to be tighter.”

“Basically what happens is that the hydrogen that leaks has itself a global warming potential, which has been considered, but then also it has an effect of extending the lifetime of methane in the atmosphere basically causing the methane to stick around longer,…”

“N two O, which is also known as laughing gas, Is the third largest greenhouse gas in terms of impact on radiative forcing behind CO two and methane. It is a global worrying potential of 273 times that of CO two on a hundred year basis.”

“Now, on a warming standpoint, we're talking about half a degree C of warming effect is due to methane, and about a little over .1 degree C, about a fifth of the warming from methane is, is resulting from enteric methane.”

“If we just said, okay, let's just assume you lose two percent methane, you lose two percent hydrogen. That means if I took that methane and I burned that in a power plant, or I took that hydrogen and I burned that in a power plant, and I'm losing the same amou…”

“You have to be really careful that you're not going to tip the system to increase, for example, nitrous oxide production.”

“We are not currently aware of atmospheric methane concentrators that are able to enhance methane from an ultra dilute to PPM to a higher level of concentration.”

“It's about, there's about 200 times less methane by volume than CO₂, and one of the major controls On the efficacy of removal is concentration, so that difference in concentration, for one, is just going to make it that much harder to do the atmospheric methan…”

“With methane, there is one key difference, which is that you can oxidize it. You can turn it into CO₂ rather than just capturing the gas and finding a place to sequester it, which is a big advantage relative to what you need to do to remove CO₂ from the atmosp…”

“Almost all of that methane Business as usual would convert to CO₂ anyway. So as soon as you're releasing methane to the atmosphere if it's a fossil source methane, then yes, that CO₂ that is eventually converted to is additional CO₂ that would, that's being ad…”

“Human sources of methane, there are some that we have mitigation alternatives for, and when we talk about hard-to-abate sectors for carbon dioxide, there are also hard-to-abate sectors for anthropogenic methane sources that we don't have good mitigation option…”

“Unlike CO₂, which you, is sticky in the sense that, you know, it's amenable to acid-base chemistry, there are ways that you can grab a hold of a CO₂. Methane doesn't really have that same, the same properties. It is symmetric, It doesn't have acid-base chemist…”

“Nitrous oxide emissions, which is a powerful greenhouse gas, third, third largest source of greenhouse gas emissions in the world behind the CO two and methane.”
