Are you familiar with paragraph 1, paragraph 2 of the Road traffic regulations? It goes like this: “Anyone who takes part in traffic has to behave in a way that no one else does damaged, endangered or more than can be avoided under the circumstances, with special needs or harassed will “. So far, this has mainly been the case with other road users. In the future, it will also apply to that climate. Because whoever damages or endangers the climate also hinders or annoys humanity.
For us drivers this means: We need others, more environmentally friendly Drive forms. Clear, Electric cars are an alternative. But what about the 46.5 million Burners? They will be on German roads for many years to come. So it takes Further approaches. Could a solution eFuels be. So that every gasoline or diesel climate-neutral from now on, provided the synthetic fuel was produced sustainably. We clarify, how this works out, What that costs – and how cars with eFuels travel.
What are eFuels?
The name sounds modern and innovative: eFuels. That stands for “Electrofuels“, so “Electric–fuel“- and should be a bit confusing. Because eFuels are filled up like normal fuel at the Gas pump and not at the socket. But: at the Manufacturing electricity is used. In fact greener current from solar and wind energy. It is used in a multi-step process hydrogen and ultimately eFuels to manufacture. Why the effort? Quite simply: The climate-neutral, liquid fuel can be an important factor contribution to the Reach the Climate protection goals Afford. Because with the green fuel you can everyone Internal combustion engine operate. The synthetic fuel is available as e-gasoline, e-diesel, e-heating oil and e-kerosene. In addition, the existing Infrastructure Can still be used from petrol stations, warehouses and ships.
critic say of eFuels that the fuel is green to inefficient. The same amount of electricity used is enough for eFuels for 100 kilometers, for battery electric cars for 700 kilometers. Of the Efficiency of eFuels is around, according to car professor Ferdinand Dudenhöffer 15th percent. That of e-cars is around 80 percent. the Advocates from eFuels counter that the efficiency is even not so decisive – since the solar and wind energy used are generated anyway. eFuels should be produced where there is enough wind and sun. For example in Africa.
In addition, other eFuels would have advantages: You own a lot higher Energy density as car batteries or hydrogen stored in gaseous form. That makes them very similar to fossil fuels. What does that mean? eFuels can be used over long distances inexpensive transport, for example by tankers. and Well to store – which is difficult with electricity.
Do you notice a difference to gasoline when driving?
One gurgles easily from large canisters yellowish liquid in the tank. No big deal for a combustion engine, because this “feed” differs themselves barely from super gasoline. It smells exactly like that and sloshes with it same viscosity to himself. Pure chemically there is between the two too none difference. Because the canister product called eFuel was brewed in the laboratory in such a way that it corresponds to mineral oil fuel. The test car doesn’t really care, the main thing is the stuff ignites reasonable. And that’s the point: How is it going with eFuel, are there differences between natural and laboratory products?
Clear no! The test car behaves with eFuel not different than usual under super care. The three-cylinder comes to life with a typical chatter and does what everyone expects. The 136 hp accelerate him sufficient fast at highway speed. The aisles are evenly turned out, the 1.5-liter hardly affords Slack. Unfortunately, the motorway was not part of the test track, but we do not doubt that everything would run normally here too.
The question remains: Tolerates the engine the new fuel? Such concerns are unfounded. eFuel is made up of the same Elements together like super, can be “constructed” even more purely. All Burners should be able to take him. Says Prof. Dr. Thomas Koch, Head of the Institute for Piston Machines at KIT (Karlsruhe Institute of Technology): “Negative influences on the drive train have not yet been diagnosed, are not expected. Rather are even smaller ones Product benefits possible with eFuels. “So: bring on the synthetic super!
Where does the synthetic fuel come from?
When it blows hard, it is Markus Speith in his element. The 54-year-old is with Siemens Energy Project manager for a factory that is being built 13,700 kilometers away from Munich: in Patagonia in the south Chile. Siemens and Porsche are currently building one there together with other partners Pilot plant to the Manufacturing from eFuels. “The groundbreaking ceremony took place on September 10th 2022 130,000 liters of petrol are shipped to Europe annually, “says Speith. Ab 2026 should it yearly up to 550 millions liter be. And how do you make eFuels? “First to harvest we the wind, “says Speith. The electricity it generates drives you Electrolyzer at, the water in the ingredients oxygen and hydrogen disassembled. If now that hydrogen still CO2 is supplied, is created in a multi-stage process petrol. The plant in Chile is a Beginning. Speith: “Even if eFuels have a significant one contribution will have to perform in countries like Germany in the future E-drives the car market dominate. But in many other regions and areas of application, for example Planes and Ships, that won’t work. There eFuels are used for Decarbonization contribute.”
What will eFuels cost?
So far, eFuel has been produced in small pilot plants and is still far of the possibility of one nationwide care removed. The production under Laboratory conditions takes care of one for the time being Price per liter about 4.50 euros – which is of course not competitive with fossil fuels. How else could it be? The world is designed for the extraction, processing and consumption of fossil raw materials. Around 14 billion liters of crude oil were funded last year – Every day! It is estimated that around half of this is used to produce fuel. Even if eFuel in great scale is manufactured and the production of intermediate products is optimized, should also be used for green gasoline Prices sink. Estimates suggest that 2026, in the optimal case, the price per liter is already up 1.60 euros has decreased. And already 2030 could the Liters according to an optimistic estimate around one euro costs. That would make it competitive with fossil fuels. And until then, eFuels can at least be mixed with fossil fuel.
Which means of transport can still use synthetic fuel?
In times of climate change there is a new term: Flight shame. No wonder that Aviation industry as soon as possible Eco kerosene wants to change. Like internal combustion cars, airplanes can do this too sustainable fuel refuel. Lufthansa is Pioneer, already burned 10,000 tons per year. That is theoretically enough for 100 flights from Europe to America – sounds like a lot, but Lufthansa does it every day! Only recently has airline boss Carsten Spohr therefore called for a significant increase in the production of eco-fuel. In October now also wants to World Aviation Association IATA present a corresponding initiative in Boston. To 2030 the aviation industry wants and has to two percent Procure the fuel used from sustainable resources. That means: 200,000 tons of eco kerosene are then necessary annually.
