The former Audi developer Roland Gumpert wants to improve emobility with a methanol fuel cell. Electric experts think: that is unrealistic and "Green methanol" Don’t give it. In a column for site, Gumpert answers his critics.

For links on this page, Site receives. A commission from the dealer, Z.B. For marked. More info"The supposed miracle car from Ingolstadt" a report on my development was titled. I would like to go into that. Nathalie is of course not a miracle car, but a brilliant and really realistic addition to existing drive concepts.A small company as we are (Gumpert Automobile GmbH consists of 23 highly motivated specialists) does not have a large marketing budget like the large car manufacturers and still has to attract attention to be noted. That’s why we have ours "Nathalie", But which can be compared with the Taycan electric sports car from Porsche.Here are some data:

Nathalie – the "Taycan hunter"

  • Range Porsche Taycan – at a speed of 130 km/h (25 kWh per 100 km) = 340 km (with a battery size of 93 kWh, although the battery is not quite "empty" and therefore not the full battery capacity can be used).
  • Range Nathalie – at a speed of 130 km/h (25 kWh per 100 km) = 752 km (with a battery size of 70 kWh and a methanol tank of 65 liters; 1 liter of methanol = 1.82 kWh, so the entire energy capacity is 118 kWh
  • Top speed Taycan: 250 km/h
  • Top speed Nathalie: 300 km/h
  • Acceleration Taycan 0-100 km/h: 4 sec.
  • Acceleration Nathalie 0-100km/h: 2.5 sec.
  • Weight Taycan up to 2395 kg
  • Weight Nathalie up to 1750 kg

Study shows what is feasible

To be honest: neither a Porsche Tacan nor a Nathalie "needs" you nowadays! We built the Nathalie as a lighthouse project, it is a marketing tool. But that’s so common in the automotive industry, because what it is about is the technology behind it.In short: If you bring all-wheel drive, two electric motors, two 2-speed gearboxes with Torsen differential, a 68 kWh battery and a 65 liter tank, as well as our new technology, the GPC (Gumpert-Power-Cell) under – Then this is the proof that it is also possible for every car, truck and bus.

No opponent of emobility

The electrification of traffic is not an unsolvable problem. Electric cars have absolutely their right to exist. There are many applications (z.B. City car / delivery vehicle) in which pure electric vehicles are unbeatable. In my estimate, 20% of our vehicles will be pure electric vehicles in the future. It should be mentioned here again that we are absolutely not opponents of e-mobility, as we subordinate to our critics.

Methanol from electricity! Hydrogen from electricity?

What about methanol that our car is refracting? The federal government has declared Germany to be hydrogen country and promotes hydrogen technology with nine billion euros. Methanol is a refined hydrogen. Green hydrogen is made from water using electrolysis. For electrolysis, (waste) electricity is used, which you cannot save at the moment (such as electricity of wind turbines at night). However, this hydrogen is difficult and is transportable with very much cost. Therefore, it is cheaper to make methanol out of this hydrogen by "mixing" the hydrogen with CO2.

Reality in Scandinavia

There are many paper factories in Scandinavia and methanol producers right next to it. The CO2, which has been immigrated to the wood out of the air for years, is not let out into the "free", but mixes it with the hydrogen made from wind-night stream to methanol. The same applies to concrete factories and waste incineration plants, steel producers, etc. The worldwide methanol production is in change. In China it is already being used as an admixture or direct fuel for cars in combustion engines. In the future, methanol will no longer be produced from fossil sources. "Green methanol" will be the future.

If you compare methanol with gasoline, methanol only has 50% of the energy. Then you would have to take a tank twice as large as with a gasoline vehicle. However, the efficiency of our GPC power cell is 45% and a maximum of 30% for a petrol engine. So you get something again. But it is not about the size of the tank. You can make it almost arbitrarily tall and thus extend the range. It’s about the time of refueling. With the Nathalie it only takes three minutes!

Farm for three minutes instead of shopping for 30 minutes

Critics have accused me of the production of a litder of methanol would devour 12 kWh of electricity with current-based processes. That is completely wrong: Power to X at E-Methanol is already 52% today. This shows that 52 percent remain in the Power to X product per kilowatt hour used. But the electricity costs are actually irrelevant. Because the hydrogen production systems will be created where it "Waste"-Electricity gives z.B. Solar power in the south or night wind power in the north.

Site Climate frit should come: We will soon refuel all CO2-neutral?

A Porsche drives with the energy that was necessary for the production of a filling of a Nathalie methanol tank, 1700 km, a Hyundai Ioniq 2500 km; The Nathalie also drives 2250 km purely electrically. It is of course true: Purely electrically, when using primary energy that I support, you can achieve the best efficiency! With the Nathalie and of course also with all other vehicles with the GPC, you can load the battery with a charging station and fill the methanol tank on the right side with the piping pistol.

There are abundance of regenerative energies

Methanol is just as much as hydrogen and other e-fuel energy for which you need a lot of energy when manufacturing; But what is economic and ecological when using excess regenerative energy. I was accused of embezzling information on energy consumption or range. But the statement in the BR controvers contribution "800 km of electrical reach and refuel for 3 minutes" is absolutely right.The really serious disadvantage of an electric vehicle is an empty battery. The car is standing on the street and can usually not even be towed. Equipped with a 25 kWh GPC or with a 15 kWh GPC, drive with an empty battery in the "Nathalie" Although only guidelines and when it goes uphill, speeds are only possible with trucks. But they don’t stop! And if the methanol tank would also be empty and the car really stands, you can even make the vehicle mobile again with a five-liter reserve canister.

CHIP Long loading times ade: hydrogen sedan in the practical test

Friends of pure battery cars are happy to argue that the battery prices would quickly fall further. But assumptions about the amount of future battery prices, i.e. Z.B. Prices for vehicle batteries in 2026 are completely illusory and pure assumptions. We are calculating the prices at the present time. Compared to a conventional battery vehicle, our vehicles only need 25% of the original battery. With the saved price (75% of the original battery) we can pay the GPC.We are not sure whether the money saved is enough for the additional tank. However, we are sure that our system will find many customers who are ready to pay more money for more car. The all-wheel drive has also been produced and sold millions of times, although it is a little more expensive than a single-axle drive.

With hydrogen you have a transport problem

If the Paris climate protection agreement is to be reached, green hydrogen will certainly be introduced from sun or windy countries. But how do we organize the transport? Liquid at minus 260 degrees (for this alone you calculate 1/3 of the existing energy) or under pressure of 800 bar? With the energy you need to refuel a single hydrogen car with 800 bar tank, a diesel car can drive almost 200 km. Or you don’t get the idea of refining the hydrogen? Take CO2 and mix it with hydrogen. Out comes methanol. Methanol can be pumped through pipelines, or transport with trucks or ships. All large and small methanol producers in the world are in the process of producing methanol fossil-free in the future. I am convinced that this will be our future, because this will combine the best two worlds: electrical driving with the everyday suitability of the fast tank process. Because who wants to spend hours on a charging station for hours on a long vacation or business trip?

  1. Nevertheless, the fuel cell methanol becomes…
    …drive nothing for the mass. That is u. A. on the insufficient amounts … Waste current and co2 and the too high technical effort (with a correspondingly high purchase, maintenance and repair costs). Finally, in addition to the methanol tank, fuel cell and a large battery are required. Incidentally, a range of 1.000 km at battery-operated electric cars will soon be standard. In terms of engineering, the fuel cell methanol drive is certainly a masterpiece, but unfortunately not to be implemented on the market in the required size.

    Unfortunately, the mass (without solar cells) only has to buy normal consumers, the electricity from the monopolist is expensive. That is the real reason. Wait how high the electricity price will.

  3. E-bus can also burn.
    Oh dear, an e-bus can burn? Do you know how many buses have burned down with a diesel engine? I think your comparison lack facts u. You are basically against electric vehicles. You reach into the trick box u. Compare, without your own knowledge, at a bad level. You should study mechanical engineering, with a focus on vehicle technology at RWTH Aachen. You learn something for life.

    I recommend that this in Site in the truest sense of the word "fire"-Current video: "Electric bus (in China) opens up to flames when charging and triggers chain reaction…", pull in. And after that we are welcome to see each other again "real sensitivity" entertain of parking bans for BEV vehicles in underground garages. There you could be happy that these BEV buses were outdoors. Unthinkable what would have happened if they had been parked in a closed bus depot…You would have the building right away "be able to tear off". In view of these pictures, it is like you "Horror scenario", To imagine a TG full of BEV-VEHIKEL under a residential building. "Irresponsible" It would never be possible. Now the last one should also "BEV dreamer" wake up!

  5. Why now this distraction?
    Also hybrid and fuel cell vehicles (including "Nathalie") currently have flammable batteries and thus the same problem. However, non -flammable batteries are currently only one question (under 5, possibly even under 2 years).

  6. All marketing
    The hybrid concept methanol-electro sounds interesting because the really serious disadvantage of an electric vehicle is an empty battery. And that’s why the electric cars also literally sneak over the highway because even at the speed of the direction of the direction, the capacity rapidly goes into the knees. The fabulous acceleration values and top speeds are only marketing. Even from the fantasies with a range of 700 km, only half becomes quickly – if at all – and if there is no quick charging station, charging takes an eternity. That is also the reason why in the E-Autoland NO.1 Norway Most of them have a diesel or petrol engine for the long-distance route because in Norwegian winter on the further hallway with the electric car is definitely not funny!

    I would look at the overall hobby estate. Electric cars are a disaster here. You should make that out. The concept of methanol makes sense and it offers enough advantages. You should send several drives into the race. The pure concentration on electric cars is not clever.

  8. Funny contribution
    1) The methanol car is also an electric car-only that it loads the battery via methanol-FC. 2) You think the concept makes sense, but forget that a large battery is also installed here. Then why does it have a better ecological balance – especially since the energy use per km is 4x higher? Did you understand the concept at all at all?

    1. There will be no electricity that can be used for the methanol gain for cars, because the methanol generated in this way is urgently for gas heating, industry, aircraft, … needed. And so the methanol will cost as much as the electricity costs required for this. 2. If you take the two efficiency together 52% for methanol gain and then 47% in the car, there is only an overall efficiency of only 23.4%. Who buys a car for which you ultimately need more than 4 times as much electricity or. around the factor of 4 higher energy costs

    Someone has ever dealt with the production of the PEM membrane? It is a polymer with a half -life! What does it mean over time and then no longer acts as a membrane! Very expensive in production, since a conductive polymer made in an electrolysis. C4H5N . Please look for the price per gram once. Drugs are cheaper! So mass goods ?

This, for methanol, to use CO2 for clean combustion at the same time is brilliant. I agree with the explanations of the experienced engineer, it is an alternative to pure battery technology. We should trust our German engineering power.

  12. Mr. Heuchert, you seem
    … from the subject & close to the project. Probably engineer himself. respect. Question about the "technology behind it": Why do you keep the methanol BZ drive with a WTW efficiency of maybe 15%-compared to the BEV drive with approx. 70% WTW efficiency – for "awesome"? What justifies the alternative economically, ecological & efficiency when BEV soon have real ranges of 500+ km?

  13. It just doesn’t lead away
    past the fuel cell. No matter whether PEMFC or DMFC. As long as we do not see a significant range of reach at batteries, no innovation in energy density or. Battery structure or a dense quick load network in the area in Europe. BEVS in the current form are suitable as a second car for big city hipsters or bacon belt shopping car for parental leave.

    Let it! We take that "Folk car" the Germans, the VW and the e-variant ID3. WLTP range of 330-550km. For this you get realistic ranges at 130kmh/ 170-270km. If you want the maximum, you have to calculate from 49600 € list price, for around € 32000 you get 170km vacation range, which after 30 minutes of charging stop, not 20 minutes, reduce 80% charging to 136km until the battery is completely empty. This is due on their 800km day trip 6 charging pops with 180 minutes duration. After many and relaxed vacation trips, I took two breaks in Italy/France, without refueling (diesel), on over 100kmh on average. I didn’t need 6 charging stops to do this. Take the calculator and just calculate!

  15. Example trip – recorded
    The cruise control was predominantly (where possible) to 160 km/h, i.e. again significantly higher target speed. 1108km route. Average inclusive. Breaks (72 min) were 94km/h, without breaks 104.6 km/h. The point is: at the target speed of 130 you do not create 100 in reality, unless at night. Real data, no estimate.
