The ELEMENT EINS project aims to develop a way to transport "green energy" on an industrial scale from the production site in the north of Lower Saxony to industrial consumers. This is to be achieved by a power-to-gas plant that produces green hydrogen with the help of wind energy. This green hydrogen will then be fed into the existing gas infrastructure and made usable for industry, but also for the mobility sector.

In the ELEMENT ONE project, a plant with a capacity of 100 megawatts is to be built that can produce hydrogen on an industrial scale. Ultimately, the plant will produce up to 20,000 m³/h of green hydrogen and blend it into the gas grid. 

The pilot plant is to be gradually connected to the grid in 2022 and generate gas using wind power. This will open up new storage potential for renewable electricity, as generation can be decoupled from consumption over time.

The aim of the project is to achieve a comprehensive coupling of the energy, industry and mobility sectors. Thus, the green hydrogen is not only to be transported via existing gas infrastructure from the North Sea to industrial consumers in Bremen or the Ruhr area, but also made available for mobility.

The wind power required is to be produced in East Frisia, which is highly available both on land and at sea. The power-to-gas pilot plant will be built in the municipality of Diele in the district of Leer, where a central hub of the electricity and gas infrastructure in northern Germany is located.

ELEMENT EINS was funded by the Federal Ministry of Economics and Technology as a "real laboratory of the energy transition" in 2019. The experience gained in the project is to be made transparently available to the market to enable further development of power-to-gas technology.

In future, the project is to be carried out in close cooperation with the "Clean Hydrogen Coastline" project. A corresponding cooperation agreement was signed at the end of November 2021. This is intended to turn the coastal region of Lower Saxony into a first European hydrogen cluster in which a complete value chain will be established.
