A world without gas infrastructure? If we aggressively electrify the economy, green methanol could cover most of the remaining non-electric demand - without needing large-scale hydrogen or methane networks. New paper in Joule: "A Minimal Methanol Backstop for High Electrification Scenarios"

Wie ein klimaneutrales Energiesystem mit viel Wind und Solarstrom auch in den kritischsten Dunkelflauten mehrerer Jahrzehnte funktionieren kann, wird vielfach wissenschaftlich erforscht. Gestern konnte ich dazu ein paar Sätze in den ARD Tagesthemen sagen. www.tagesschau.de/tagesthemen/...
