Mahindra & Mahindra unveiled hydrogen (H2) powered three-wheeler named Hy-Alfa, at World Hydrogen Technologies Conference on august 26, 2009. It runs on nothing bu compressed hydrogen gas and is incredibly engineered to run with absolutely zero emissions, which makes it a pleasure to drive on congested city roads. Hydrogen is, in fact, the technology and fuel of tomorrow and is the long term solution to pollution, energy security & CO2 emission related concerns. The Hy-Alfa offers a 3-seat version and a cargo version of the vehicle. The Hy-Alfa also uses an internal combustion engine instead of fuel cell to supply power to the wheels. Hy-Alfa is not a speed burner though with a top speed of around 42 mph, but it will also work in-30 degrees Celsius temperatures and will achieve around 45 mpg equivalent.
