Hydrogen leaks into confined spaces have done the boom thing. My impression is wavefront speed may be supersonic or somehow drive a lot of intensity (not my area) Wheat is scary in a silo, but in a 50 lb bag not so much. I liked the cell engineering idea with hydrogen - not sure of weight / etc tradeoffs.
