A contract to provide preventative and corrective maintenance services for the Audi e-gas plant in Werite, Germany, has been awarded to McPhy.
This decision is a consequence of a partnership between Audi and McPhy which started in late 2013, when McPhy Energy finalised the installation and commissioning of the 6mW water electrolysis plant for the Werlte installation.
The plant uses surplus green electricity to produce hydrogen from water in three alkaline electrolysers. The hydrogen is reacted with CO2 to produce synthetic methane, or Audi e-gas. It is virtually identical to the fossil, natural gas, and is distributed via an existing infrastructure, the German natural gas network, to CNG filling stations for Audi’s A3 g-tron series.
Audi produces up to 1,000 metric tonnes of e-gas per year, chemically binding some 2,800 metric tonnes of CO2. This roughly corresponds to the amount that a forest of over 220,000 beech trees absorbs in one year. Water and oxygen are the only by-products.
