Storage is trivial freshman physics (lift a weight, pump air to displace water under pressure, pump water uphill) except for batteries, which are also perfectly known physics, with numerous chemistries in mass production, a century of universal use, and working prototypes for more exotic chemistries
Thus, literally as different from fusion as is possible to express.
