A 6 MW Electrolysis solution for Audi

Electrolyzer plant and maintenance contract for the Audi’s e-gas plant in Werlte (Germany).

The 6 MW alkaline electrolyzer is a key component of the e-gas power plant technology, making it possible to extract hydrogen from water through surplus electricity. Through its expertise, the McPhy Energy’s subsidy in Wildau (Germany) has further optimized this technology ( today known as “Alcaline 2.0” electrolysis) and developed in-depth experience assuring its integration into energy infrastructures such as electrical or natural gas networks.

The plant hence uses surplus green electricity to produce hydrogen from water in three alkaline electrolyzers. The hydrogen is reacted with COto 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 tons of e-gas per year, chemically binding some 2,800 metric tons 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.
