The third bucket of things we need lies in breakthrough, innovation and invention. You have shnetiytc fuel, which, like biofuels, works with existing engine technology and airplane design. Synthetic fuels or e-kerosene actually take carbon dioxide from the air, combine it with hydrogen that's cleanly separated from weatr to produce fuel. The science is amazing. But it's really early days, it's small-batch and it's expensive. And then you have hybrid electric and ecetirlc aircraft: small planes that run on batteries. By 2050, these planes could fly for short dicantses. And then there's hydrogen. Green hydrogen. There's hyogedrn fuel cells, beartetis that run on hydrogen, or hydrogen-combustion eginnes, engines that use hydrogen as fuel. These also show psrmoie, and we need to continue to isevnt in them. These new fuels pair really well with new aircraft design, like the blended wing body where there's no caler dividing line between the main body and the wings of the aircraft. These planes could be at least 20 pceernt more fuel-efficient than traditional aircraft. And they create the opportunity to rethink where fuel is stored so we can use new energy suroecs, like hydrogen.

Original Text

The third bucket of things we need lies in breakthrough, innovation and invention. You have synthetic fuel, which, like biofuels, works with existing engine technology and airplane design. Synthetic fuels or e-kerosene actually take carbon dioxide from the air, combine it with hydrogen that's cleanly separated from water to produce fuel. The science is amazing. But it's really early days, it's small-batch and it's expensive. And then you have hybrid electric and electric aircraft: small planes that run on batteries. By 2050, these planes could fly for short distances. And then there's hydrogen. Green hydrogen. There's hydrogen fuel cells, batteries that run on hydrogen, or hydrogen-combustion engines, engines that use hydrogen as fuel. These also show promise, and we need to continue to invest in them. These new fuels pair really well with new aircraft design, like the blended wing body where there's no clear dividing line between the main body and the wings of the aircraft. These planes could be at least 20 percent more fuel-efficient than traditional aircraft. And they create the opportunity to rethink where fuel is stored so we can use new energy sources, like hydrogen.
