Flow - making hydrogren happen. The pipeline for hydrogen stretching from northeast to southwest.

With the "making hydrogen happen” project, the so-called Flow project, GASCADE, ONTRAS and terranets bw are planning a high-performance pipeline system for green hydrogen. Existing infrastructure will be used to connect international hydrogen markets with industrial customers in Europe. First pipeline sections could be converted as early as 2025 already, thus providing a significant building block in the European hydrogen ramp-up and the energy transition.
