Electro or e-fuels (or power to liquid/gas) are electricity-based gaseous or liquid fuels which can be used in internal combustion engines.
According to a new report by Cerulogy for T&E, e-fuels only have meaningful climate benefits if strict sustainability criteria are observed throughout the production process. The key factors determining the sustainability of e-fuels are the source of electricity (it must be renewable), the source of CO2 (ideally air capture) as well as impacts on land and water.
