Lockheed starting with not using a tokamak is probably the best idea. ITER has sucked up 16 billion Euros and still is far from completion. When done, it will create only 500MW (goal is for 1000 seconds).
One way I've heard suggested to store both clean and non-clean energy is Flywheel Kinetic storage with magnetic bearings and in a vacuum to reduce friction. I don't remember a lot about it (saw an online video or a TED conference or something on it), but I recall a company buying off-peak hour electricity and then selling it at peak hours, so it may be the Beacon Power listed in the wiki article.
