Through consistent foot traffic, day four in Hannover brought the opportunity to reflect on the industry. The number of exhibitors in the hydrogen and fuel cell area has increased. Many PEM and SOFC companies are here to show prototypes and gather competitive intelligence. 

It is encouraging to see growth in the industry, including development of new fueling technologies - necessary to overcome a key commercial challenge. The research and development crowd was in heavy attendance, many from universities around the world, and some of whom were very proud to see their research resulting in commercial products! Most notably, these scholars see Plug Power's technology as industry-leading and standard-setting.
