Production and containment are two obstacles for our harnessing the vast energies released when antimatter makes contact with regular matter. How close are we to producing and being able to contain antimatter in sufficient amounts for space vehicle propulsion purposes?

I'm afraid it's more than just production and containment that is preventing the use of antimatter for propulsion. Yes, it does produce a lot of energy when it annihilates with normal matter, but that energy is uncontrolled, and produced all at once. Mostly as very high energy photons.

In my opinion, the most likely propulsion method that makes use of matter-antimatter reactions would be an Orion-like vehicle, propelled by periodic explosions underneath a giant metal plate.

As for your questions about production and storage:

Recent data released by CERN states that when fully operational their facilities are capable of producing 107 antiprotons per second. Assuming an optimal conversion of antiprotons to antihydrogen, it would take two billion years to produce 1 gram of antihydrogen.

Containing antimatter is a problem till date but that can be contained by means of magnetic or electric confinement.this however is not feasible yet.
