We've already had discussions about anti-matter being used as a fuel
one day, but typically there were criticisms about the stability of the
magnetic bottles used to contain the anti-matter.
Here is an article about positronium as a possible future power source:
http://focus.aps.org/story/v16/st16
So if positronium could be stored at low-temperature and low-density as
a Bose-Einstein Condensate, then could it be harnessed as a high-energy
power source for a launch vehicle?

sure if electron-positron anihilation can be harnessed in such a way so
as to control the direction in which the resulting high-energy photons
are emitted, but if that were possible then wouldn't it reduce the need
for radioactive shielding around your power source?

Did you bother to read that article? Positronium decays far too quickly
(< 1 microsecond) to be useful for energy storage.

In space, positronium could be produced with solar energy and stored in
huge bags (bags made with a metalic film, an electric conductor, and
with a very high voltage)
