Plainly named but patently cool, eFuel is a synthetic gasoline that burns exactly like the traditional stuff yet has minimal environmental impact.
But how is eFuel made? [...] the hydrogen is combined with carbon dioxide captured from the air, and through the magic of chemistry it all gets synthesized into methanol, which is then converted into gasoline.

How can this be carbon neutral if it burns like traditional gasoline? Doesn't it produce CO2? Does the synthesis process capture exactly the same amount of CO2 than what is released from combustion?

Also, if it is possible to do this, isn't there also a fuel that would not release CO2 at combustion while consuming CO2 for synthesis?
