Newswise — Global air travel consumes more than 100 billion gallons of jet fuel annually. That’s expected to more than double by 2025 to 230 billion gallons. Despite the current pandemic, these projections reflect future anticipated passenger demand. Airlines want to meet market demands while simultaneously reducing their carbon emissions.
In fact, airlines around the world have committed to carbon-neutral growth beginning in 2021. As part of that commitment, U.S. airlines have set a goal to reduce carbon dioxide emissions by 50 percent by 2050 compared to 2005 levels.
Reaching that goal will not be easy. Electric planes won’t make much of a dent because the batteries can only power the smallest of light planes. The only way to achieve emission reduction goals is with liquid fuels that have a lower carbon footprint: Sustainable Aviation Fuels (SAF).
Pacific Northwest National Laboratory’s John Holladay co-authored a recent report that presents a pathway to low-cost, clean-burning, and low-soot-producing jet fuel.
