A car called the Quant e-Sportlimousine and presented at the 2014 Geneva Motor Show is the first electric car powered by salt water and is now certified for use on European public roads.
“For the first time an automobile featuring flow-cell electric drive will appear on Germany’s roads,” said Nunzio La Vecchia, chief technical officer at NanoFlowcell, a company which designed the car.
“We are extremely proud that as a small company we have developed such visionary technology and are now able to put it into practice. But this is only the beginning of our journey of discovery.”
A few months after making a debut at the 2014 Geneva Motor Show, the Quant e-Sportlimousine underwent an in-depth inspection and received official approval to be tested on public roads in Germany and Europe from certification provider TÜV Süd based in Munich, Germany.
The car is powered by the electrolyte flow cell power system, which is a part of the NanoFlowcell technology.
The system works in a similar way to a hydrogen fuel cell, except for the fact that salt water is used for storing power. In particular, two liquids with metallic salts, which act as the electrolyte, are combined in such a way that the electrochemical reaction takes place.
After that, electric motors use this reaction to generate electricity, which is then stored and distributed by super capacitors. The efficiency of this system reaches 80%, since the car has almost no moving parts in it, and the produced waste heat is insignificant in comparison with cars powered by lithium-ion batteries.
