Even though there are many manufacturers who are harping on the need for use of clean fuels, Audi, the brand with four rings has taken this a little bit further by opening the first e-gas plant. This plant will help in the production of sustainable fuels in the near future.
Audi e-gas plant has been designed to produce synthetic methane gas from CO2 and renewable sources of electricity. Through this project one can expect a steady transition towards usage of cleaner and greener fuels for transportation needs. The plant works by supplying electrical charges to boost electrolysis after which the hydrogen gas collected is them combined with CO2 to form methane.
This e-gas or Audi e-gas as it will be known as is similar to that of natural gas and thus can be piped to CNG station all over Germany. EWE a nearby power supplier will be supplying CO2 for the production process at the gas plant. This CO2 is basically a waste product which is collected from the biogas plant powered by EWE.
The Werlte, GermanyÂ plant is being built on an area of 44,132 sq ft and will be constructed using quality materials and techniques which will be helpful for enhancing the overall efficiency of the gas plant. It will produce enough gas to run 1,500 Audi A3 for 15,000 kms every year. For more information, scroll down.

Topping-out ceremony for the Audi e-gas plant
Cutting-edge power-to-gas plant in northern Germany
Audi e-gas project is milestone for sustainable mobility
e-gas production to begin in early 2013
Audi will today celebrate its e-gas plant in Werlte, Germany with a topping-out ceremony. The brand with the four rings is the first carmaker to build a production plant for sustainable fuels. Its end products will be hydrogen and synthetic Audi e-gas, to be used as climate-friendly fuel for vehicles such as the new Audi A3 Sportback TCNG.
The worldâ€™s first industrial plant for generating synthetic methane (e-gas) from CO2 and renewable electricity is under construction in Werlte, Germany. It will produce gas that can be fed into the natural-gas network. â€śThis power-to-gas technology opens up new possibilities for sustainable mobility and tomorrowâ€™s energy industry. The e-gas project marks a transition toward alternative forms of energy for automobiles,â€ť explains Reiner Mangold, Head of Sustainable Product Development at AUDI AG.
The Audi e-gas plant, which can convert six megawatts of input power, will utilize renewable electricity for electrolysis. This process splits water molecules into oxygen and hydrogen, or Audi e-hydrogen, which could one day power fuel-cell vehicles. Because there is not yet a widespread hydrogen infrastructure, however, the hydrogen is then reacted with CO2 in a methanation unit to generate renewable synthetic methane, or Audi e-gas. Chemically speaking, this e-gas is nearly identical to fossil-based natural gas. As such, it can be distributed to CNG stations via the natural gas network and will power vehicles starting in 2013.
The CO2 used in Audiâ€™s e-gas plant is a waste product from a nearby biogas plant, operated by energy provider EWE. The CO2, which would otherwise pollute the atmosphere, is chemically bonded into the fuel at the Audi e-gas plant â€“ making Audi e-gas climate-neutral. The e-gas plant will annually produce about 1,000 metric tons (1,102 US tons) of e-gas and will chemically bind some 2,800 metric tons (3,086 US tons) of CO2. This corresponds to the amount of CO? that 224,000 beech trees absorb in a year.
Audi e-gas is an energy-rich fuel ideal for internal combustion engines. The Werlte facility will generate enough CO2-neutral e-gas to power 1,500 new Audi A3 Sportback TCNG vehicles 15,000 km (9,320 miles) every year. This compact five-door car will arrive at dealerships in late 2013. Audi plans to launch a second TCNG model, based on the A4, in 2015.
A special certification procedure will verify that the same amount of e-gas that owners purchase for their Audi TCNG vehicles is fed into the network by the e-gas plant. A similar balanced-cycle method is used to verify procurement of green power.
The German energy industry can benefit from Audiâ€™s e-gas strategy, as it addresses the nagging challenge of how to store renewable electricity efficiently and irrespective of location. The ability to store large quantities of wind or solar energy via the dual electricity/gas principle could significantly foster the expansion of renewable energies. The Audi e-gas project can be easily replicated in any country with a natural-gas network.
The Audi e-gas plant in Werlte is being built on a site owned by energy provider EWE AG measuring 4,100 m2 (44,132 sq ft) overall. Ground was broken in September 2012. As owner, Audi is constructing the plant in cooperation with equipment manufacturer SolarFuel GmbH. They have prioritized the optimization of energy flows. Waste heat generated during electrolysis and methanation, for example, is used in the adjacent facility â€“ thus tremendously enhancing overall efficiency.
Once the electrolysis units have been installed, the methanation reactor will be supplied and connected. This specialized unit some 16 meters (52 ft) in height will be provided by MAN, a sister company in the VW Group. e-gas production will begin in early 2013 and feeding into the public natural-gas network in summer 2013.
AUDI AG was honored in November 2012 for its e-gas project. The Working Group for Efficient and Environmentally Friendly Energy Use (German: ASUE) presented Audi with 15,000 euros and â€“ in the Environmentally Friendly Mobility category â€“ a Gas Industry for Innovation and Climate Protection award.
