In the Bavarian town of Hohenwart, a successful pilot project named H2Direkt took place where households and a commercial customer transitioned to heating with 100 percent hydrogen via the existing gas distribution network. The project involved partners like Energie Südbayern, Energienetze Bayern, and Thüga. The transition was seamless, with no need to modify the grid itself. Upgraded heating systems from Vaillant were installed in households, and positive feedback was received from customers. The project showcased that hydrogen infrastructure is reliable even in extreme temperatures. The integration of hydrogen hardly differed from natural gas operations, and safety measures like adding the odorant THT were implemented. The successful transition in Hohenwart highlights the potential for expanding hydrogen networks to serve other customer groups. The Federal Ministry of Economics plans to establish a hydrogen core network, while Netze BW Öhringen in Baden-Württemberg has already tested hydrogen transport in existing gas networks.
