We had the opportunity to present our ideas to a group of passionate sustainability advocates at the Energy Bunker in Hamburg-Wilhelmsburg, a remarkable transformation of a Second World War bunker into a hub for generating and storing renewable energy. During this event, we engaged in fruitful discussions about upcoming hydrogen projects with Christian Heine (CEO at Hamburger Energiewerke) and explored the latest trends in mobility with Anjes Tjarks (Hamburg Senator for Mobility).
