How important synthetic fuels, also known as e-fuels, will be in a future energy system is a question many are hotly debating these days. The answer, of course, depends on whom you ask and whom they represent. To bring some facts to the table, energy institute ifeu recently conducted a study for German environment agency UBA to determine the amounts of carbon dioxide and other pollutants emitted by fuels produced through power-to-X.
Despite the current wave of enthusiasm about the potential of hydrogen, there is much discussion and much uncertainty about the role of synthetic fuels. If you follow the current debate, you sometimes get the impression that E-Fuels are either another saviour or a spawn of evil.
