“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.”

Mukhopadhyay: 9-seat electric planes only get 150km range with current batteries
“With current battery technology, and including sort of the standard reserves that are required for flights, you would, you probably get about a 150 kilometers out of the nine seater aircraft, which is a lot less that's close to a hundred miles”
Mukhopadhyay: Electric Aircraft Need 500 Wh/kg Batteries Near Theoretical Limit
“Whether you're talking about nine, 19, or a hundred seat aircraft, you require at least a doubling of current battery technology, and that's really a significant increase, especially when you're thinking about just lithium ion batteries. That is close to sort …”
Mukhopadhyay: Electric aircraft can only address 0.1% of global passenger kilometers
“These electric aircraft in the end don't actually end up playing a significant role in terms of the global aviation market. We're talking about close to like .1% of the global aviation traffic can be serviced by these aircraft. Now that's in terms of sort of p…”
Mukhopadhyay: Fleet turnover caps 2050 hydrogen aircraft penetration at 6% to 12%
“And so our projections suggest that even though hydrogen aircraft could service a third of passenger aviation, the actual market penetration is probably going to be more like six to 12% by 20 50. Because of that slow fleet turnover rate.”
Mukhopadhyay: Non-CO2 aircraft impacts like contrails cause twice the warming of CO2
“They say that current research suggests that the impact, the non CO two impacts, which includes these contrail formation can be twice as much as the impact from CO two alone.”
Mukhopadhyay: Airport hydrogen production infrastructure costs as much as a new terminal
“And the estimates for about, for what kind of Investment that would require is on the order of sort of build all of that onsite production and storage, it would cost as much for the airport to build a whole new terminal.”
