Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡
E-Fuels, so the story goes, could allow using existing cars and infrastructure like gas stations. However, E-Fuels are extremely inefficient.
In 2022, Siemens Energy, Porsche, and the Chilean company HIF inaugurated the Haru Oni pilot plant in Chile's windy Magallanes region, which turns CO2 and Hydrogen into Methanol and small amounts of Gasoline. How's it going? 🧵

"Antoine de Saint-Exupéry, author of the second-most translated book of all time, colorfully explained (also in French) the importance of dress in our society through a simple anecdote: the planet of the Little Prince had been discovered in 1909 by a Turkish astronomer that nobody took seriously because of his traditional clothes. Repeating his conference in 1920, this time in suit and tie after a reform in his country, he had been applauded at length."

We have to talk about burning trash🗑️🔥
Waste incinerators / waste-to-energy plants that generate electricity and heat are an enormous and often underestimated source of CO2 🏭💨🌎. For example, in Germany, a country where waste-to-energy plants are common, their emissions are higher than those of cement.
Waste incinerator operators will often claim that half of their emissions don't count 🌿 or even that they already have net-negative emissions 🌎. I disagree with both 🧵
