Toyota Mirai - The Hydrogen Revolution?

Courage is when you just tackle things. Success is when it works. Toyota will launch the Mirai in Germany in autumn, presenting the first mass-produced hydrogen-powered electric vehicle. Until then, there is time for a few thoughts on the topic.

Mirai - The fuel cell is becoming a reality

Hydrogen, fuel cells, electric vehicles. These three terms somehow belong together. Even if we have been talking about the fact that soon, soon our cars will only run on hydrogen for almost 20 years, it will take until autumn 2015 before the end customer - theoretically - buys a hydrogen-powered car from the dealer can. Why theoretically? Why did it take so long?

Even the electric car itself has a history that is almost as old as that of the automobile itself. But electricity as an energy supplier was never as easy to package as the rather stupid idea of ​​gasoline as an energy supplier. Or diesel. Both fossil fuels are finite and that is just one of the problems. In addition, the energy density is rather lousy. If you compare the efficiency of electric drives with those of gasoline engines, then the gasoline engine actually has to retreat into the last corner of the underground car park and be ashamed. But still. The principle of “refueling and bunkering” fuel was easiest to implement with gasoline and diesel engines.

You can see the yellow tanks in the back. The fuel cell is located under the front seats. The electric motor and power electronics are located under the bonnet.

Energy transition under the hood

With the Mirai, Toyota is introducing a full-size sedan in the format of a Lexus GS. At 4.89 meters long, it offers space for five passengers and is easily recognizable from the outside as something “special” thanks to its futuristic design. The Mirai's 153 hp electric motor and power electronics are located under the hood. The two hydrogen tanks were housed in the rear of the vehicle and the 56 kg fuel cell, together with the necessary control elements, ended up under the seats in the first row of seats. Toyota expects this layout to provide balanced weight distribution, which in turn benefits driving pleasure and handling.

The Mirai will have a curb weight of 1.850 kilograms (without driver) and with up to 178 km / h also a reasonable (German) highway speed. But probably that is more than secondary, the question will be much more important: Who buys a mirai?

And where will you refuel?

These are the questions that pioneers have to deal with. The current plans to expand the hydrogen filling station network are a little late. Instead of the planned 50 gas stations you will probably have only 2015 gas stations at the end of 23. That is manageable. Manageable is also the production planning of Toyota. 2015 will produce 700 vehicles, by the way in the same factory where the Toyota supersport LF-A was already made. In 2016 you want to build 2.100 cars and then make 2017 over 3.000. The first annual production is already sold out, according to information from Toyota and that although the vehicle was previously introduced only in the US and Japan.

The two plastic tanks have a volume of 122,4 liters and hold 5 kg of hydrogen. The Mirai should then be able to drive up to 500 km. And the only thing that comes out of the “exhaust” is water vapor. A tempting prospect and exciting technology.

Bridge into the niche future?

But it is also clear that a fuel cell is just one of many technologies for the future. The development of battery technology will show up to what range pure electric vehicles make sense and from when on we will switch to the future “long-distance electric technology” fuel cell/hydrogen.

The price and the planned quantities make the Mirai look like a niche solution in the short term. The purchase price of 78.580 € contributes to the exclusivity of the Mirai as well as the blunt restriction of the numbers.

Hybrid pioneer Toyota

But if a manufacturer can clean up the market like this with new technology, then it could well be the Japanese automobile company Toyota. Why not? With the long history of hybrid automobiles since the first Prius in 1997, one can see a clear success as a “pacemaker” in the automotive industry.

And finally ...

Whether it is just courageous or successful – that will have to be judged in retrospect. Whether hydrogen alone represents the energy transition is probably not the case. But it sounds logical and understandable if you understand hydrogen as an “energy storage” in the future. Its use is multifunctional and, above all, environmentally friendly when combined with the fuel cell.
