An Introduction to Electro-fuel (e-fuel) Technology

Production of e-fuels promises a route to effectively limitless, carbon-neutral fuels without the controversy of biofuels around land use, sustainability and competition with food. E-fuels can also be referred to under the umbrella of power-to-X (P2X), X being liquid or gaseous products, including hydrogen, methane, alcohols or drop-in hydrocarbon fuels. However, e-fuels are still at an early stage of development with various routes that can be used for production.
