I'd bet on the new battery techs because "How is hydrogen more flexible? Electricity just needs wires (and batteries at either end). The wires already exist. Hydrogen needs wires (the power has to get from the powerplant to the hydrogen facility), compressors, fuel cells, very expensive dispensing facilities (about 2 orders of magnitude more expensive than dispensing power!)...and, potentially, pipes or tanker trucks (a LOT of tanker trucks. A hydrogen tanker truck only supplies a tenth of the utility that a diesel tanker truck does because even highly compressed hydrogen has very low volumetric energy density) ....and if we want to forego pipes/tanker trucks then hydrogen requires double to triple the grid strength for the same utility that a battery system requires (because of low efficiency) A hydrogen system is ridiculously expensive compared to a pure battery one." https://www.reddit.com/r/energy/comments/z01i54/hydrogen_vs_batteries/ Also the energy density of hydrogen has the upper limit, but new battery techs will only get much better beyond the current capacity.
