Renault knows how to amaze its public. It is famous for the most original and creative concept cars. Now Renault is looking at a hydrogen ICE for aI will explain why this is a surprise. The hydrogen option for cars is not very popular because of the low efficiency of hydrogen fuel cell powertrains. From wind turbines or solar panels to the wheels, you get about 22% energy efficiency with a hydrogen fuel cell as used in the Toyota Mirai. In a battery electric vehicle, this is 72%.
But e-fuels are a lot less sexy than hydrogen. E-fuels are safer and easier to handle. The transport and burning in the engine is the same as gasoline, but the marketing potential is nil, nada, nothing — maybe even negative. And half the world is waiting for hydrogen in cars. They know it is the next big thing after gasoline and diesel.
This new hydrogen ICE concept car is nearly as clean as driving on sunshine in a BEV — the hydrogen turns into H2O, no CO2 is produced. The hydrogen is burned at high temperatures, causing just a small problem. It produces the same greenhouse gas NOx as fossil fuel cars, but this is difficult to explain to the public, so it does not count.
There is a risk that this ICE will be blocked from entering urban areas, just like its fossil fuel burning cousins, because of the NOx production. But that would be so unfair — this is the new savior hydrogen that the car industry has been waiting for so long!
