Excerpt from the article:
Millions of combustion engines – powering machines, vehicles and aircraft – will remain in use for decades to come. Instead of replacing them, a Swiss chemical engineer is developing a greener alternative: a synthetic, “drop‑in” fuel that works with existing engines and infrastructure.
Inside her labyrinthine lab at the Swiss Federal Laboratories for Materials Science and Technology (Empa) in Dübendorf, a network of pipes and custom-built modules hums away as Alessia Cesarini shows off the prototype e-fuel unit she took two years building.
She aims to turn it into a business offering a viable alternative to conventional fossil fuels.
“There are lots of systems with combustion engines still running, and the idea is to provide a locally produced and less-polluting solution,” she explains.
Transport accounts for 47% of Switzerland’s energy-related CO2 emissions, versus 25% globally. A Swiss study estimates that around two million combustion-driven vehicles will remain on the country’s roads by 2040. Globally, Bloomberg estimates that 55% of cars will still run on combustion engines by that time. Also, for hard‑to‑abate sectors such as aviation, long‑term decarbonisation will depend heavily on the adoption of renewable fuels.
Cesarini’s approach is simple: “The goal is a solution that works with existing vehicles and infrastructure – sustainable both environmentally and economically,” she says.
The nazis used this technology during WWII it’s that old. Coal to liquid technology fueled their war machine, literally. And the entire process can run on any source of syngas, even syngas made from CO2 reverse water gas shift reaction, and hydrogen from electrolysis. You can use solar power for the entire process, it’s just incredibly incredibly energy inefficient once you make a finished fuel product and burn it. Like 19th century steam engine thermal efficiencies for each 1w of green power into the system vs each fraction of a watt of energy burned in an ICE.
