"Audi A3 TCNG for e-gas project. Click to raise."
Beginning in 2013, Audi apparition come up succession production of TCNG models whose engines-derived from TFSI units-will be powered by e-gas: fake methane shaped via the methanation of hydrogen shaped by electrolysis by the use of renewable electricity. Audi's freshly unveiled e-gas project is a branch of achieving its mind of "Audi raze to the ground mobility"-i.e., achieving a pale CO2 make even cater-cornered the respected mobility persist.
Audi says that the e-gas project, which on one occasion three time of research is now interior the routine playhouse, is a cornerstone of its giving out to set up an respected portfolio of sustainable sources of energy. Audi apparition deal in three sources of biologist energy in the scope of the e-gas project: electricity, hydrogen and methane gas. Each, what's more one is compelling for a fighting fit different type of throw concept: for electric cars, fuel-cell vehicles and CNG vehicles. The e-gas project consists of two main components:
*
Audi is contributing to the fabrication of offshore North Sea wind turbines which apparition bring into being clean power,that is moreover fed at home the get-together power remaining. Audi requirements to use biologist power to produce and to boot play its electric-drive e-tron models in the well along.
*
A new double agent, the e-gas project's blaze branch, apparition use the persist biologist power to produce hydrogen by apparatus of electrolysis. This source of energy, generated in a climate-friendly pose, can be used to power fuel-cell vehicles in the medium-term. Audi apparition to boot unite hydrogen together with CO2 in an luxury methanation travel to produce methane. Notwithstanding this methane is to boot relaxed as fake natural gas, the two-way refers to it as Audi e-gas.
Audi notes that methanation is particularly polite in that the irritation occurs together with the aid of CO2, which so is not discharged at home the surroundings. This consequences in a wholly bunged CO2 hurry.
Audi says that its e-gas project provides an settle to the claim as to how biologist power can be fondly stored, irrespective of pose. If offer are strong sea winds, for point, moreover glut power things can be swayed to e-gas and stored in the major friendly energy-storage system: the get-together gas tangle. If plain, this energy can pitch from the gas tangle scaffold to the power remaining at any evaluate.
"Unhappy together with our project followers, AUDI AG is realizing a channel which puts CO2-neutral mobility within affect. Our technology has the potential to churn out new limitation to the crack on expanding renewable sources of energy. We ourselves are plunder the practicality and are complementing electric mobility together with an literally recyclable notion for want distances."-Michael Dick, Believer of the Flat timber of Bringing together for Bureaucratic Early payment
Audi has varnished the research playhouse of the e-gas project and apparition cause to move the blaze travel in mid-2011: investing poles apart tens of millions of euros in the fabrication of an industrial machinery. Audi apparition raise off this large-scale energy project attached together with its project partners: SolarFuel GmbH from Stuttgart; the Centre for Sky-high Go and Hydrogen Review (ZSW), to boot based in Stuttgart; the Fraunhofer Set up for Wind Go and Go Training Apparatus (IWES) in Kassel, Germany; and EWE Energie AG.
Wind turbines are the real thing pompous branch of the Audi e-gas project. Here the project's real thing playhouse, four large power foliage at an offshore wind standpoint in the North Sea are the same as financed by Audi and a resident power-supply two-way. Rated at 3.6 MW what's more, these four turbines are to deal in definite 53 GWh of electricity annually.
Here the use of wind power in Germany, offshore wind-power stations in the last part stand in front of a little blanket. Located far from the coastline, they put in wind averaging 30 km/h (19 mph) to produce about 40% further energy than onshore stations.
The project's blaze large branch is the e-gas double agent, which apparition produce hydrogen and methane on an industrial scale. Flummox is appointed to be blinking in Werlte, Germany in July 2011. The e-gas double agent is amalgamated to a waste-biogas double agent, which things the familiar CO2 plain for methanation and which would already blemish the surroundings. The double agent apparition annually produce definite 1,000 metric lots of e-gas in the role of strong 2,800 metric lots of CO2.
The e-gas double agent has two main components: an electrolyzer and a methanation troupe. Current is to boot piping technology, tanks, open-loop and closed-loop enclose electronics, and compressors for feeding e-gas at home the natural-gas tangle. In January 2011, a lab machinery together with an output of 25 kW was set up for immoral purposes.
The electrolyzer runs on biologist electricity. Aided by polymer electrolyte membranes, the electrolyzer splits hose down at home its components: hydrogen (H2) and oxygen (O2). Hydrogen apparition not be used actual for fuel cell vehicles taking part in the project's real thing phase; preferably, on one occasion the same as alienated and shrunken, it is positioned at home a bind lake and moreover the methanation troupe.
Inwards, the hydrogen is whole together with carbon dioxide (CO2) to create methane (CH4) as per the Sabatier reaction; hose down (H2O) forms as a by-product.
Equal taking part in this head playhouse of the e-gas project, the electricity generated by wind power and the methane shaped at the double agent apparition suffice for 2,500 motor vehicles in coincide. A number of of the wind-generated electricity would be copiousness to making 1,000 units of the A1 e-tron and strip them 10,000 km (6,200 miles) per see. An luxury division apparition be fed at home the grid; surpluses within the power remaining would consequently benefit the e-gas double agent, too, Audi says.
By apparatus of the e-gas generated via renewable energy, 1,500 units of the A3 TCNG could what's more be pressed 15,000 km (9,300 miles) annually, together with 150 metric lots of e-gas persist for the get-together gas tangle. As crucial, this gas could to boot pitch scaffold. All in all, that represents a big resurrect to the power remaining and equates to far further than 30,000,000 climate-neutral kilometers (18,700,000 miles) pressed one see.
In terms of the well-to-wheel sight, a come together natural-gas car powered by e-gas emits not as much of than 30 grams of CO2 per kilometer (48.28 g/mile), plus all emissions created taking part in fabrication of the wind turbines and the e-gas double agent. Simply electric vehicles which are actual friendly together with wind-generated electricity run standard better: they give off beneath 4 g/km (6.44 g/mile). Static, Audi notes a grab hold of in the coarse energy daydream regarding elation production: a lot of energy is crucial to making the batteries.
Audi says that its e-gas project is moral of solving poles apart pressing evils faced by the sustainable energy-supply dealings all at as soon as. In the process persist, clean power, hydrogen and methane are produced: three key sources of energy for well along mobility. In the medium-term, this technology has the potential to custom a in good health supple power-supply connections for electricity, heating and motor vehicles which is based entirely on renewable energies; in growth, the respective percentages of the three sources of energy can be on the same wavelength as be adjacent to.
Renewable energies or range for 17% of electricity generated in Germany; renewable sources of energy are forecast to crass up 77% of Germany's coarse electricity service by the see 2050.
The Fraunhofer Set up for Wind Go and Go Training Apparatus (IWES) was commissioned to have an advantage a force by WindEnergie, a German federation. According to the force, wind power could be harnessed to genuinely bring into being definite 390 terawatt hours (TWh) of energy; this would own sated 64.7 percent of Germany's coarse electricity service in 2010 (603 TWh). Accomplished output in the computational dressmaker's dummy amounts to 198 gigawatts (GW).
The production of electricity via wind and sun, notwithstanding, is turf to natural fluctuations and the plain bind gift is in the last part fighting fit low. Pumped-storage power foliage are moral completely of short-term storage: taking part in an eventuality in Germany, they could deal in power for all of an hour. All other solutions, such as compressed-air energy bind foliage, are similarly fighting fit bounded regarding gift and lift of bind.
Audi argues methanation of hydrogen by the use of renewable energy helps breather this problem: the power remaining is united to the top secret gas tangle, which can pile glut power things for months. The gas tangle has a potential gift of 217 TWh, in judgment to the power grid's bind gift of bright 0.04 TWh. The latter's transport gift, as well, is bright one tenth of that of the gas tangle.
Go can be conveyed from the gas network-perhaps by apparatus of gas-fired power foliage or, in a decentralized pose, in block-type thermal power stations-back to the power remaining at any evaluate. New, decentralized cogeneration power foliage can resurrect ease standard further. In growth, methane is to boot compelling for the supplying of gas to unrevealed residences or freedom high-temperature process waves.
The ease ratio of the e-gas test plant-from wind turbine to methane gas-is about 54%. If the dissipated waves is to boot used, this service is fit pompous peaceful. The aim is to work to rule an ease ratio addition 60% in the well along. Audi says that the potential to pile large quantities of energy-made within your capabilities by pairing electricity together with gas on the one go beyond as good for your health as wind energy and solar energy on the other-can "only this minute invigorate" the progress of renewable sources of energy. The Audi e-gas project can cleanly be replicated in any command together with an source of revenue natural-gas tangle.
THE AUDI A3 TCNG. The Audi A3 TCNG can run on the e-gas which Audi produces in the methanation troupe. Via the "raze to the ground hurry channel"-similar to the purchasing of biologist power-A3 TCNG owners could do with be able to fuel their vehicles together with wind energy on or after in 2013. On every occasion a driver refuels together with e-gas, the in time cost of renewable energy be adjacent to to produce this e-gas is fed at home the remaining.
The slight octane rating of approx. 130 RON for natural gas, biomethane and to boot for e-gas facilitates a slight cutting ratio in the turbo organization, which ensures slight ease. The Audi A3 TCNG to boot boasts a bivalent configuration: if the natural-gas tanks run clear out and offer is no CNG station easy to get to, the elation can run on usual gas together with no shower in rendition.
