So many companies claim to have developed the future of road car propulsion that those making genuine strides run the risk of being ignored. Luckily, German firm Quant is avoiding such a fate, as its innovative ‘flow-cell’-powered vehicle has just been approved for real-world testing by the German TÜV safety body.

The Quant e-Sportlimousine was first revealed at the Geneva Motor Show back in March, powered by what the company called ‘nanoFLOWCELL’ technology. In essence, flow-cells combine characteristics of a traditional battery, and fuel cells. Electrolyte fluid is circulated around two cells mounted side-by-side. Between these cells is a membrane that allows electrons to pass through. The electrical current generated from this flow of electrons can be used to power a vehicle—and that’s exactly how the e-Sportlimousine works.
