Audi has opened its e-gas plant in Werlte, making it the first automobile manufacturer to develop a chain of sustainable energy carriers. Water and oxygen are the only by-products. The waste heat given off during methanation is used as process energy in the adjacent biogas plant, significantly increasing overall efficiency. At this facility, microorganisms use water (brackish, salt or wastewater) sunlight and carbon dioxide to produce high-purity fuels.
