Here's something to give existential threat assessors hives, and the rest of us hope.
It's Ryan Weed, the CEO of Positron Dynamics who claims to have solved antimatter's production and containment issues. He's getting around the storage problem by the elegant method of avoiding it totally. They're generating positrons on the spot (using Krypton79 decaying to Kr78 ) and firing them into deuterium to catalyze fusion. The neutrons from the reaction transmutes the Kr78 back to Kr79 and the associated 'splody travels out the tailpipe and goes "woosh". Research is looking promising, but there are already some interesting spinoffs, which include a nuclear battery with a yield of as much as 100 watts a kilogram.
Here's an animation of how their system is supposed to work.
Peter Thiel has invested in the company and their development has been promising enough that NASA gave them a big grant last March.
Time will tell.
