San Antonio, TX / Alpen, Germany, 29-March-07 - Some 1,500 attendees visited last week's Hydrogen Expo US, this time held in San Antonio, Texas, to discuss the developing hydrogen industry and strategies to bring hydrogen cars and other products to the consumer. The latest in hydrogen and fuel cell technologies was showcased by more than 90 international exhibitors at the premier networking event, which is part of the National Hydrogen Association's (NHA) Annual Hydrogen Conference. The hydrogen vehicle Ride & Drive, which attracted conference degates, media representatives and the public alike, included cars from exhibitors BMW, DaimlerChrysler, Honda and Toyota. In the well-attended Seminar Forum located inside the exhibit hall visitors had the chance to learn more about new products and projects from more than twenty free presentations.
