The organisers say: "The concept of hydrogen as a clean and renewable energy source is nothing new. However, a number of technical and economic challenges need to be overcome before hydrogen can be fully realized as a major contributor to reducing global carbon emissions. Hydrogen Technology Expo North America is a solutions-driven trade fair and conference dedicated to the development of new technologies to overcome these technical challenges and propel hydrogen into the mainstream for stationary and mobile applications." IDTechEx Technology Analyst Dr Conor O'Brien is presenting at the event and IDTechEx are exhibiting, at stand 1320.
