The biggest roadblock to a H2 economy is storage. We have developed a closed-loop process to de/absorb H2 using a metal hydride 3x denser than pure, liquid H2.

Company Summary

Currently we are focused on producing, storing and distributing H2. Two prospective markets include micro-grids and transportation. We are in the middle of researching the prospects of using a low-temperature (400F) reaction to convert H2O to H2, which is absorbed to precipitate sodium borohydride (as energy dense as gasoline). NaBH4 currently sells for over $20/kg, more than $18,000/ton. Or combine it with a fuel cell like a battery, for energy.
