Besondere Beachtung verdient dabei insbesondere das Herstellungsverfahren des Ausgangsstoffs #Methanol sowie ggf. die Herkunft des CO₂.

Dann isses natürlich kein "e"-Fuel, denn der Elektroanteil entfällt hierbei ja komplett.
Das ist das, was CAC m.W. einsetzt, vgl. futurefuels.blog/im-labor/synth…

Aber egal, welchen der beiden Wege ein Hersteller von "echtem" e-Fuel wählt: in beiden Fällen braucht es zunächst #Wasserstoff,...
🚨Study on future options and costs of energy imports for Germany🚨
Our study comparing future options for energy imports to Germany and their costs has finally passed peer-review and is now published.
A thread 🧵
Our study comparing future options for energy imports to Germany and their costs has finally passed peer-review and is now published.
A thread 🧵
🔑Key findings
- Germany has many options for import
- No one-size-fits-all: Costs strongly depend on what and from where you import
- Costs for renewable alternatives and prices for fossil counterparts converged in last year
(visualisation created with AI b/c it's trendy)

Our review paper on recent advances in solid oxide cells for #electrolysis has been published today in @ScienceMagazine ( science.sciencemag.org/content/370/65… ) Here are the main points from the paper (a thread, 1/15) 👇
Electrolysis (using electricity to drive chemical reactions) is a key technology for tackling #CO2emissions in the areas of our economy that are difficult to #decarbonize: heavy transport (planes, ships, trucks) and the production of chemicals, steel, cement, and glass. (2/15)
For heavy transport, e.g. large planes or container ships, direct electrification (batteries) is not an option due to low energy density of batteries compared to liquid fuels. Climate-friendly fuels can be made by combining electrolysis with chemical synthesis (e.g. FT). (3/15)
"Development is not the big issue here – both on the engine and fuel side. The problem is the business case. So far it makes no financial sense to build zero emission ships." – Jakob Steffensen, @DFDSGroup Head of Innovation & Technology #IVIW2020
.@hellings_bart of @GoodFuelsmarine is convinced that the #ammonia and #methanol route is promising, but the business case is not yet there as current demand is insufficient. #IVIW2020
“#Aviation contributes 2-3% of CO2 emissions, but takes decarbonising very seriously. There's no silver bullet to eliminate our impact, we need a series of solutions: batteries; fuel cell tech; & H2 combustion engines—a #renewables surrogate.”—@Airbus’s Glenn Llewellyn #IVIW2020
