Dreyfus: No existing technology can currently concentrate ultra-dilute atmospheric methane
“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.”
Dreyfus: Natural sources drive 35% of methane emissions with no mitigation tech
“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…”
Dreyfus: Megatons of methane removal match gigatons of CO2 removal
“When you introduce that global warming potential, that 80 to 90 times more potent over a twenty-year lifetime, yes, if you're talking about climate impact, the amount of methane that you have to remove for a comparable climate impact to CO₂ When, you know, we'…”
Dreyfus: Maintaining methane's temperature impact requires ongoing tail removal
“Because that methane would have gone away eventually over time, to maintain that temperature impact over time, you actually need to continue to remove the methane, not at the original scale, But there's this concept of effective methane removal, so you have yo…”
Dreyfus: Methane capture works for point sources, not ambient 2 ppm levels
“Some of the technologies that we're going to be talking about may already have lab-based or pre-commercial or even commercial applications at that dairy barn or coal mine shaft, but not yet at the two PPM level.”
Dreyfus: Atmospheric methane is 200 times less concentrated than CO2
“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…”
