2011 Audi TCNG e-gas Project
Audi has turned the corner on their new "Audi balanced mobility" moto with the launch of a new project called the TCNG e-gas project. The TCNG e-gas project will use wind-generated electricity to manufacture hydrogen by means of electrolysis. Hydrogen can be used in the future as a source of energy for fuel-cell vehicles or, in an additional step, can be used to manufacture methane. It is chemically identical to natural gas and can power combustion engines. CO2-neutral mobility is our goal," says Audi Chairman Rupert Stadler.
Audi TCNG and-gas project is the name that the German automaker has given its methane and hydrogen by electrolysis would be the first time that a house is committed to produce its own fuel. The project would also introduce gas-mains in the German clean energy.
The Audi A3 TCNG can run on the e-gas which Audi produces in the methanation unit. In Germany alone, natural gas is available at some 900 CNG stations and counting.
Similarly to natural gas, the combustion of e-gas also creates far less CO2 than premium unleaded does. The high octane rating of approx. 130 RON for natural gas, biomethane and also for e-gas facilitates a high compression ratio in the turbo engine – which ensures high efficiency. The A3 TCNG's gas tanks, which store the e-gas at a pressure of 200 bar, offer enough capacity for long drives.
