The car industry is trying to save the combustion engine. Their best bet: synthetic fuels. They're hailed as being carbon neutral and the quickest way to get old cars off fossil fuels. Sounds great? Well, if you look closer, synthetic fuels are the worst way to decarbonize individual transport. Reporter: Kai Steinecke Video Editor: Nils Reinecke Supervising Editor: Malte Rohwer-Kahlmann We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our channel explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess. #PlanetA #eFuel #ClimateChange Read More: Overall assessment of eFuels: https://www.agora-energiewende.de/fileadmin/Projekte/2017/SynKost_2050/Agora_SynKost_Study_EN_WEB.pdf Efficiency of eFuels: https://www.sciencedirect.com/science/article/pii/S235248471830266X# Potential risks of hydrogen-based e-fuels in climate change mititgation https://www.nature.com/articles/s41558-021-01032-7 Costs of eFuels: https://theicct.org/sites/default/files/Electrofuels_Fact_Sheet_20181005.pdf The energy density advantage: https://royalsociety.org/-/media/policy/projects/synthetic-fuels/synthetic-fuels-briefing.pdf Special Thanks to Severin Hänggi and Roland Dittmeyer for their valuable insight to eFuel production and efficiency.
