PSA Peugeot Citroen is developing a “Hybrid Air” powertrain that addresses the limited range of compressed air energy storage technology by combining it with a gasoline powered internal combustion engine (ICE). The company plans to have Hybrid Air powered vehicles on the road by 2016.
PSA’s Hybrid Air technology is similar to current battery electric hybrid vehicles, such as the Toyota Prius, but it uses compressed air for energy storage rather than batteries. A hydraulic pump/motor unit recovers energy generated by the ICE and from braking and deceleration, storing it in a compressed air energy storage unit.
PSA says for city driving, its Hybrid Air system provides fuel savings of 45 percent and increases a vehicle’s range by 90 percent compared to conventional engines with the same power rating. In standard body styles, such as the Citroen C3 and Peugeot 208, the company says the system achieves certified fuel consumption (combined cycle) figures of 2.9 l/100 km (81 mpg) and CO2 emissions of around 69 g/km.
