e-Gase aus Werlte (abgeschlossen)

In 2013, AUDI AG opened a new e-gas plant in Werlte, Lower Saxony. The plant was the first in the world to generate feed-in synthetic natural gas from CO2 and renewable electricity on an industrial scale. The plant was taken over by kiwi AG in 2021. Since then, production has also focused on synthetic LNG and green hydrogen.

Using the local conditions - that was the motto of AUDI AG, which built a plant in Werlte in Emsland in 2013 to produce synthetic natural gas on an industrial scale. Sources that were available in the immediate vicinity were used to produce the synthetic gas. Renewable wind power from the coast and_CO2 produced in a neighboring biogas plant from the utilization of residual materials were used to produce synthetic natural gas.

However, due to energy policy and market structure developments in the mobility sector, the focus of the plant operator AUDI AG increasingly changed, meaning that the production of hydrogen in an electrolyser also became successively more important. In 2018 and 2019, a new compression plant was also added to enable the transportation of hydrogen in trucks.

During this phase, it was also decided to produce liquid methane (LNG) in the future. For this purpose, green hydrogen from the company's own electrolyser and carbon dioxide from the neighbouring biogas plant will be used for methanation. This methane can then be liquefied and used as LNG.

In 2021, kiwi AG finally took over the plant from AUDI AG and has continued the stronger focus on the production and use of green hydrogen to this day. The electrolysis capacity of 6 MW will be used for methanation on the one hand - on the other hand, hydrogen will also be made transportable as an energy carrier.
