Better Storage Through Chemistry

This article focuses on production of a hydrogen fuel system for a DaimlerChrysler fuel cell minivan by Millennium Cell Inc., a developmental-stage company based in Eatontown. Millennium Cell’s hydrogen-on-demand system stores hydrogen in the form of sodium borohydride, a chemical whose chief use today is for bleaching paper. Mixed with water, the chemical makes a fuel that can be stored as a liquid in plastic vessels under ambient temperature and pressure. The mixture is neither flammable nor explosive. Millennium Cell continues its research. It is attempting to drive down catalyst costs. Improving catalyst durability is another constant challenge. The company continues making key changes in the packaging of its hydrogen-on-demand technology to reduce the space it occupies. As for Millennium Cell’s researchers, their desks filled with abundant technical challenges, they undoubtedly have plenty to do besides worrying about the future.
