World premiere: Audi opens power-to-gas facility

Posted on 25. Jun, 2013 by in Volkswagen Canada

Audi opens a e-gas plant in Werlte currently creation it a initial car manufacturer to rise a method of tolerable appetite carriers. It starts with immature electricity, H2O and CO dioxide. The finish products are hydrogen and a fake methane: Audi e-gas.

“Audi is holding a hulk step toward a mobility of a destiny today,” pronounced Heinz Hollerweger, Head of Total Vehicle Development, in his debate during a inauguration. “Audi is a usually manufacturer worldwide with such innovative technology. Research into synthetic, environment-friendly fuels is a core of a powerful e-fuels strategy.” Reiner Mangold, Head of Sustainable Product Development, added, “The power-to-gas trickery we built in Werlte can turn a guide plan for a whole appetite revolution, distant over a bounds of a company.” Peter Altmaier, German Federal Minister of a Environment, Nature Conservation and Nuclear Safety, also commended Audi’s joining in his welcoming address.

The e-gas plant works in dual routine steps: electrolysis and methanation. In a initial step, a plant uses over-abundance immature electricity to mangle H2O down into oxygen and hydrogen in 3 electrolyzers. The hydrogen could one day appetite fuel-cell vehicles. For a time being, however, in a deficiency of an area-wide infrastructure, a second routine step is carried out directly: methanation. The hydrogen is reacted with CO2 to furnish fake methane, or Audi e-gas. It is probably matching to hoary healthy gas and will be distributed around an existent infrastructure, a German healthy gas network, to a CNG stuffing stations. The plant is scheduled to start feeding Audi e-gas to a grid in tumble 2013.

The Audi e-gas plant will furnish about 1,000 metric tons of e-gas per year, chemically contracting some 2,800 metric tons of CO2. This roughly corresponds to a volume that a timberland of over 220,000 beech trees absorbs in one year. Water and oxygen are a usually by-products.

Audi built a e-gas plant in partnership with a plant construction dilettante ETOGAS GmbH (formerly SolarFuel) and a plan partner MT-BioMethan GmbH on a 4,100 m2 (44,132.03 sq ft) tract of land owned by EWE AG. Ground was damaged in Sep 2012, and a topping-out rite was distinguished in December. The fit use of appetite flows is a tip priority in a prolongation method of a plant. The rubbish feverishness given off during methanation is used as routine appetite in a adjacent biogas plant, significantly augmenting altogether efficiency. In return, this plant reserve a rarely strong CO2 compulsory as a simple building retard for a e-gas. This CO2 so serves as a tender element and is not issued to a atmosphere.

It is expected that a e-gas from Werlte will appetite 1,500 new Audi A3 Sportback g-tron vehicles for 15,000 kilometers (9,320.57 miles) of CO2-neutral pushing each year. The 1.4 TFSI in a five-door indication can bake healthy gas, biomethane and Audi e-gas; with a bivalent pattern it can also use gasoline. This gives it a sum operation of some 1,300 kilometers (807.78 miles).

Customers can sequence a share of e-gas when they squeeze a car. This enables them to take partial in an accounting routine that ensures that a volume of gas that they put in their car during a healthy gas stuffing hire is granted to a grid by a Audi e-gas plant. Payment and billing is rubbed around a Audi e-gas refueling card.

The Audi A3 Sportback g-tron, that is scheduled for launch late this year, consumes on normal reduction than 3.5 kg (7.72 lb) e-gas per 100 kilometers (62.14 miles). CO2 tailpipe emissions are reduction than 95 grams per km (152.89 g/mile) in a NEDC. Driving with Audi e-gas is climate-neutral, given a CO2 generated when a car is driven had been firm formerly during a prolongation of a e-gas. Even in a extensive wheel-to-well investigate that includes a construction and operation of a e-gas plant and a breeze turbines, CO2 emissions are only 20 grams per kilometer (32.19 g/mile). The groundbreaking environmental footprint was recently approved by TÜV Nord.

The Audi e-gas plan transcends a car industry. It shows how vast amounts of immature electricity can be stored well and exclusively of plcae by transforming it into methane gas and storing it in a healthy gas network, a largest open appetite storage complement in Germany. With a e-gas project, Audi is a partial of and a motorist of a appetite revolution. Major German appetite utilities have given taken adult a thought of power-to-gas cogeneration and are following Audi with initial projects of their own.

The e-gas plan is partial of Audi’s extensive e-fuels strategy. In together with a e-gas plant in Werlte, Audi also operates a investigate trickery in Hobbs, New Mexico, USA, for a prolongation of e-ethanol and e-diesel in partnership with Joule. At this facility, microorganisms use H2O (brackish, salt or wastewater) object and CO dioxide to furnish high-purity fuels. The vital idea of these projects is to use CO2 as a tender element for fuels and so urge a altogether footprint substantially. The e-fuels plan is an critical post of Audi’s sustainability initiative.
