Flying is dirty, at least in terms of global warming. But sustainable fuel made from plant-based sources instead of petroleum might offer a greener way to travel.

it would include a $4.3 billion research program as well as tax credits for SAF manufacturers in the proposed $3.5 trillion reconciliation bill that is currently being debated in Congress. The White House also said three federal agencies would work with a consortium of US airlines to boost the use of sustainable fuels to 3 billion gallons by 2030.

Patrick Gruber, the CEO of Gevo, says that after a decade of manufacturing SAF, the technology is ready for a big scale-up that might happen if the Biden tax credits are passed and airlines continue their demand for his green fuel. “The technology is well developed. The products are proven and certified to work,” Gruber says. “Right now, it’s about deploying capital, and making sure everybody can make money.

Instead of using plants or waste oils, some entrepreneurs want to go even further by manufacturing SAF out of thin air. Well, actually by a neat chemistry trick that combines a carbon molecule pulled from COin the atmosphere with a hydrogen molecule split from water.
