The key is the rechargeable "electrolyte" fluid that the energy is stored in. This charged (one batch positive and the other negative) liquid, also called an "ionic" liquid, is circulated around two cells mounted side-by-side inside the car. Between these cells is a membrane that allows electrons to pass through in a process known as “cold burning”. The electrical current generated from this flow of electrons can be used to power a vehicle—and that's exactly how the sedan, known as the “Quant”, is powered.
Whether nanoFLOWCELL's technology is legit remains unclear, because the company is yet to allow independent testing of its cars or provide details on the internal workings of its flow cell design. However, the company has made a number of major strides. More recently, it’s managed to gain engineering giant Bosch as one of its backers, it’s received approval from the German government to test prototypes on public roads, and it’s formed a subsidiary company to start production of its future lineup.

According to Nunzio La Vecchia, the mastermind behind nanoFLOWCELL, the incredible performance is made possible due to a capacitor-based “buffer system” that allows up to 2,000 amperes when full performance is needed. Normally, around 50 amperes is continuously fed into the system.
"To our knowledge, no-one has ever before put a system delivering over 2,000 amperes on the road in a passenger car,” La Vecchia said in a statement. “We achieve this by combining our flow battery with the new buffer system.”

“It is not just a concept vehicle—it will become reality in the course of this year,” La Vecchia said. “We will be driving the Quantino in 2015 and we aim to attain approval for road use very quickly."
Interestingly, nanoFLOWCELL is already looking beyond the automotive sector for the application of its technology. Other sectors being considered are aerospace, railways and shipping, road haulage, housing construction and building services. But to expand, the company will need funding, which is why it’s considering an IPO. We sure do hope the technology doesn’t turn out to be vaporware, especially for the sake of anyone choosing to invest in nanoFLOWCELL.For more Geneva Motor Show coverage, be sure to visit our dedicated hub.
