Membership of the German hydrogen and fuel cell association DWV is going up and up. Not only that, the difficult energy policy situation at the moment means the association is gaining in importance too. For several years the DWV has been evolving into a central industry association alongside the German gas and water industries association DVGW. In order to further improve cooperation between the two organizations, in spring 2021 the DWV executive committee selected Thorsten Kasten, at the DVGW’s suggestion, to become its second chairman (see H2-international, August 2021). H2-international spoke to Kasten during the Hannover Messe about his first year at the DWV and to Tilman Wilhelm, who from April this year has headed up the regulatory policy, press and public relations work of the DVGW, about the challenges in the energy space.
