The “Flow – making hydrogen happen” project is developing a high-performance pipeline system for CO2-neutral hydrogen that extends from the Baltic Sea to the south-west of Germany. EWE, an energy service provider and storage operator, has joined the collaborative initiative of gas transport network operators GASCADE, ONTRAS and terranets bw as an associated partner with experience in hydrogen storage. EWE and gas transmission network operator and project initiator GASCADE have now signed a formal agreement, with the aim of coordinating their activities more closely and driving the growth of a hydrogen-based economy together.
