It might be simpler to react the SiHx with water first to produce SiO2

the issue altogether.
The SiO2 would collect in the mixing tank and thus be easily
reclaimed.
Good idea!
In the fuel density graph you referred to, the most commonly used
fuels lie
roughly along a diagonal of the graph, i.e. they are a good
compromise between
weight and volumetric density. The best one in that regard would
appear to be
Lithium Borohydride, which could also be utilized in the manner
just described
here above.
The reason Si is such a great element for energy transportation and
storage is, if you look at energy production on a global basis, there
is so much of it cheaply available in desert areas, where the solar
energy to refine it is located. And it has a double whammy - money
is to be made on both the energy and the byproduct. This is a fairly
quickly implementable scheme for power utilities, and the economics
certainly *were* there if they aren't now, and should be there again
soon.
