Why can't you have both?
- hannob 5y agoFuels made from carbon filtered from the air are expensive. Like... not a bit more expensive, but really expensive. While there's some uncertainty about how expensive - this is technology that doesn't exist today - it's gonna require massive amounts of energy, which is simple physics.
- pfdietz 5y agoIt doesn't really make sense to make fuels from CO2 drawn from the atmosphere if we're still pumping oil. Instead, make jet fuel from the oil, then make that carbon neutral by capturing and sequestering the CO2. This will change if green hydrogen becomes very cheap, but not yet.
