Blue Solutions has also developed another electricity storage component, known as a supercapacitor, used mainly in developing clean public transport and hybrid cars. Blue Solutions is one of the only manufacturers in the world of this type of product.

Supercapacitors are characterised by very high power density, very short charge and discharge times, and the ability to cycle several million times without deterioration. Using this technology the Bolloré Group has developed a tram that needs no major infrastructure (no rails or overhead power lines), reducing investment levels for local authorities. When coupled to a combustion engine, supercapacitors provide reductions in fuel consumption and air pollution of 20% compared with a stand-alone combustion engine.
