Me thinks many of these fuels have hidden agendas and it's not always 
obvious why a certain fuel can't make the cut.

The steam provides a controllable connection from the actual energy 
source to the end user (turbine, recip or whatever) and like you say 
"it only produces water vapor" but it isn't a energy source. The 
energy to generate the steam probably came from some fuel such as 
coal, wood, bio diesel, gasoline, nuclear or whatever and you are back 
to waste products. The steam doesn't create the energy, it only 
transfers the energy to something we can more easily use.
