Aviation

“Like, my view is, like, all aircraft, like, all, all aviation, like, all air transport will move electric here. And I think hopefully in our lifetime”

“The hardest hire in aviation is a night vision trained helicopter pilot.”

“Refrigerants are, in aggregate, actually a huge source of global greenhouse gas emissions from a climate impact standpoint. They are roughly on par with aviation, which is big.”

“And so whenever you, whenever you're engaging with a regulator, no matter if it's aviation or if it's biotech or some other thing, if you're really, really on the frontier, it means that, that the regulator doesn't necessarily understand the technology any bet…”

“In aviation beyond short haul, I actually think it seems pretty clear the path we're headed down, which is a path of blending, of largely biosaf, followed eventually by drop in fuels, probably e-fuels someday in the future.”

“I think, you know, the future of maritime, it's not going to be single fuel. So we're not going to, for example, move into one single fuel. I think, you know, as a contrast to aviation, where I think there's a convergence that we need sustainable aviation fuel…”

“And so I think most people who've taken a serious look at aviation and even considering major step changes in battery density, let's say a three times improvement in density, From where we are today, there's just a vanishingly small share of total flight miles…”

“So, so with that as a foundation and the fact that new technology isn't being adopted by 2035, if we don't do anything about aviation, it will be the biggest producer of carbon emissions and transportation.”

“What I mean is that right now aviation contributes about three percent of all world CO two emissions.”

“But our own industry projections are that by 20 50, that's going to be anywhere up to 50% of all CO two emissions everywhere.”

“And I think it is going to continue to be the case that Jet A is going to be the winner, and synthetic fuels of all stripes still have to make Jet A.”

“Steel, aluminum, cement, chemicals, aviation, shipping, and trucking. Add them up, and they represent about a third of global greenhouse gas emissions, and they're the sectors where the existing, fully commercialized, mature, and ready-to-deploy technology wil…”

“And so you can literally see, you know, in this graph, it's like, as of, you know August, 20, 22, 28,000 896 accidents with 159,859 fatalities in basically the last hundred something years of aviation.”

“Electric propulsion was just coming into its own for aviation. And it took longer than for cars, because everything for airplanes has to be lighter and more reliable. But batteries were becoming good enough, and motors were becoming lightweight enough, where y…”

“Aviation traffic volumes double about every 15 years.”

“Aviation is a relatively small fraction but that few percent is still more than the country of Germany.”

“So this is like aviation, but harder because there's not as much money.”

“In 2050, the amount of electricity that would be required to decarbonize aviation is the entire renewable energy production today. So all of the energy, renewable energy that is produced today could be used up in aviation alone.”

“So aviation represents somewhere in the range of two to three percent of global greenhouse gas emissions. If it were a country, its emissions would rank around sixth in the world, somewhere between Japan and Germany.”

“Add on the additional warming impacts of aircraft contrails, and estimates are that aviation contributes ultimately something like three and a half percent of total anthropogenic warming.”

“Steel is like eight percent of global carbon emissions. It's three times aviation.”

“I would say that what I think of as probably infeasible right now is like nuclear power plant, right? Like energy and transportation, like aviation, like at the level, like a Boeing or something like that. Very large physical businesses are still not, I think,…”
