While SAFs can be blended into the existing fleet today, they typically require at least 50 percent conventional kerosene for safe operation due to the need for certain substances like aromatics ...

But SAFs pull carbon out of circulation when they’re made—like when plants use CO2 to produce sugars—then reemit it when they’re burned, so the emissions can be basically canceled out.

SARS has infected only about 5,000 people worldwide. But SAFS -- severe acute fear syndrome -- has infected millions. We’ve got the instant global communications down fine.

But SAFs come with myriad caveats: risks of environmental harm, high costs, and currently limited supply. Ramping up SAF production while reducing environmental harm to ensure these fuels are ...

SAFs are biofuels touted as environmentally friendly alternatives to traditional jet fuel. However, through their production and use, SAFs result in a considerable release of greenhouse gas emissions.

It could be a game-changer. First-of-its-kind platform could solve major problem with modern aviation: 'We need to encourage both near and long-term investment' first appeared on The Cool Down.
