Sucking a carbon-neutral fuel out of thin air

When inMarch the European Union approved a law requiring all new cars to have zero carbon emissions from 2035, Germany managed to wangle an exemption for vehicles running on “e-fuels”. Some saw it as a charter for producers to continue flogging internal-combustion engined cars to petrol-heads. While it does, indeed, mean some petrol-powered sports cars are likely to remain in production in the future, the hope is they can be powered without overheating the planet.E-fuels get their name because they are made synthetically, using electricity. The process involves combining hydrogen with carbon to produce various hydrocarbon fuels, such as diesel, petrol or jet fuel.
