There are problems with using antimatter as an energy source. I will attempt to identify those problems here.

The issues with antimatter are easily identified, and in most cases, easily solved. The first issue is how to store a substance that annihilates all the matter that it encounters. A vaccummed container with a field of electromagnetic energy and kept as close to absolute zero as possible will do the trick, but this is quite difficult to accomplish and costs around $750,000,000 to build the necessary equipment. Another issue is where to get the antimatter, but this is being solved right now by British scientists who have already created anti-hydrogen. The problem is that it takes energy to power the machines to create it. This could be solved by using other energy sources to create the antimatter and then using the energy produced by the antimatter-matter reaction to power the machines necessary to make and harness the antimatter, obviously using only a small percentage of the antimatter produced to power the machines so that the extra energy can be used to power other things. The final problem is the gamma rays produced are often lethal or abrasive, and can destroy the machines that capture the energy released by the annihilation. But scientists at NASA are already solving this problem by using a increased amount of positrons and thus creating gamma rays that are 400 times less lethal as the normal gamma rays produced by the reaction. 

A Penning Chamber is used for storing antimatter.
