No material waste or disposal
All materials, constituting the slurry are reclaimed and or chemically reconstituted into their original state and may be used over and over again.
Core Materials are safe to use and widely available
The initial development and demonstration of the concept utilized lithium hydride. Safe Hydrogen developed the technology using magnesium hydride. Magnesium hydride offers superior cost, efficiency and safety benefits. Safe Hydrogen expect to explore other metal hydrides as well.
No Need for a New Distribution Infrastructure
While slurry must be transported to the market and returned from the market, the slurry's exceptional hydrogen storage efficiency makes it a cost efficient hydrogen fuel that - unlike other options- can meet near term DOE hydrogen cost targets.
A major cost advantage of this technology is based on the characteristics of the slurry. Slurry is a nonexplosive, noncorrosive, environmentally safe, pumpable "hydrogen fuel". Slurry can be stored, transported and pumped with existing tanks, pumps and pipelines and can therefore distribute hydrogen to the market utilizing the existing fossil fuel infrastructure. The only difference from existing fuel delivery systems is that the delivery devices such as trucks or rail tankers don't return empty. They are fully loaded in both directions. They return from delivery runs, loaded with depleted slurry that needs to be recycled.
The first demonstration of the technology (using lithium hydride slurry) confirmed the ability to produce a very reliable, controllable and dependable flow of hydrogen. The test included fueling a Ford Ranger truck. The truck had a normal internal combustion engine modified to operate on hydrogen. [view demonstration (1.3MB mpeg)]. (Note: the noise in the background is a shop compressor not associated with the demonstration.)
The demonstration technology is described in our report [1.8MB PDF] prepared for the Proceedings of the year 2000 U.S. Department of Energy Hydrogen Program Review.
