AUDI, ​“e‑gas”

To produce ​“e‑gas” (methane), car manufacturer AUDI requires electricity, water and carbon dioxide. Green hydrogen is produced and reacts with carbon dioxide to methane via chemical coupling . This synthetic natural gas can be used as a fuel in a standard gas engine. In this process, solely climate-neutral oxygen and water are generated as by-products. Since 2013, AUDI operates an industrial plant for the production of ​“e‑gas” in Werlte, Germany. The produced synthetic methane can be fed into the existing natural gas grid.
