Generating Hydrogen on Demand by Splitting Water with Al Rich Alloys

Our group has been pioneering the production of on-demand hydrogen using aluminum-gallium alloys to split water into hydrogen, heat, and alumina. Recently, we have found that we can split water on demand using solid alloys of 95 wt% Al, and 5% (Ga,In,Sn). This is both a technological and economic viability breakthrough since the expensive metal component comprises only 5% of the cost. Since pure alumina can be reduced for about $0.30/lb of Al, and the 5% component can reclaimed at $0.05/lb we can show this technology could generate electricity at $0.10/KWhr.
