Another energy source...?

The Star Trek Enterprise seems to have a heck of a lot of energy running it (just pretend it's real because for all we know it could be). Now what is that energy it's running off of? And can we use it in the future or is it really just some other fiction story?
The energy the Enterprise runs off of is matter-antimatter which are negative and positive anti-particles that neutralize each other but when in contact with matter it explodes which would make it hard to control.
If only we could figure out how use the antimatter as a new energy source. If we could find a way to use it as our energy source then we'd have less pollution on this planet and once we start traveling out to other planets we won't start polluting those planets either.
But first we'd have to figure out how. How would you attain matter-antimatter?
Antimatter is thought to be in a parallel universe and break through the 'walls' that hold it in that universe. Also another way was by high-energy particle collisions.
Then there's the question of how we can store and use it.
Matter-antimatter reacts with matter and causes an explosion. Trying to hold matter-antimatter in a metal box or levitate it in air would be futile. Air is matter. Atoms are matter. So technically if you wanted to hold matter-antimatter then you'd have to use a vacuum and also a type of magnetic field around it to hold it out of atoms way.
How would you use it as an energy source?
Hopefully, manipulating and stretching the magnetic field, we'd be able to extract a few particles and move them through a complicated system vacuum to another secured magnetic field in another machine.
The downside (and possible reason why we might not use it) in the use of matter-antimatter as an alternate source of energy is that matter-antimatter needs more energy then it gives to work it. The matter-antimatter engines/etc. would need another source because of the energy it takes itself. So if you have a plane running off of a matter-antimatter engine then it'd need another type of energy source to 'feed' off of.
Now I think that I'd like to somehow research this energy source and see if it would help to have more then one engine together so that the number of engines would feed off of each other and sustain each other with the right energy amounts.
