Some are for e-cars, others prefer hydrogen, and then there are those hoping for e-fuels that haven’t even been invented yet. Hold on, there’s already an e-fuel: hydrazine. Natural scientist Christian Mähr explains what this is all about and what “Autoland Austria” actually means.
Recently, at this point, I had Dr. Hans-Joachim Glaubrecht, who thirty years ago powered a car with a hydrogen peroxide turbine. It is now in the museum in Chemnitz. CO2-free operation, water vapor comes out at the back – and oxygen.
Also in the museum, this time in Vienna, is a Puch moped, model MS 25. It was electrically powered with a hydrazine fuel cell. It was invented by the Austrian Dr. Karl Kordesch, who worked for Union Carbide Corporation in Ohio.
Hydrazine has the formula N2H2 – it consists of nitrogen (symbol N) and hydrogen (symbol H). What does not occur is carbon (symbol C). Hydrazine releases the hydrogen onto a catalyst surface, the fuel cell absorbs it and burns it with oxygen from the air to form water, generating electricity that powers the vehicle. What comes out of the exhaust? water vapor and nitrogen. For anyone who doesn’t like chemistry: the air around us consists of 80 percent nitrogen, which is completely harmless.
