Green H₂-Hub Haren, Germany
Self‑Sufficiency With Wind Power and Green Hydrogen
At the Green H₂‑Hub in Haren, wind energy is transformed into stored green hydrogen to power local mobility, agriculture, and more. Two Quest One ME450 PEM electrolysers work alongside wind turbines and battery storage to make renewable energy a reliable source for the region’s future.
How the Green H₂‑Hub Haren Enables Decentralized Hydrogen Energy Supply
The Green H₂‑Hub Haren project in Lower Saxony is a pioneering model for regional energy independence. Initiated by CEC Haren and delivered for Westnetz, the hub uses local wind power and smart energy storage to produce and store green hydrogen for regional use in mobility, agriculture, and the wider energy system.
At the heart of the project are two Quest One ME450 PEM electrolysers powered by electricity from a nearby community wind farm. With connected battery storage systems and an advanced energy management system, surplus wind power is captured, stabilised, and converted into hydrogen, which can then be fed into the natural gas grid or used in other sectors.
This sector‑coupling approach helps Haren move toward full energy self‑sufficiency. By stabilizing renewable generation with electrolytic hydrogen production and longer‑term storage, the project opens up new pathways for renewables beyond electricity alone.
