There are plenty of other storage solutions that are cheaper than lithium ion batteries and vastly more efficient than hydrogen. Even just cabling energy around is an option. E.g. the UK is looking at a solution for getting a few GW of Moroccan solar energy connected to their grid to supplement their wind power (which they have throughout the year) and modest amounts of solar which is a bit more seasonal. The fallacy in your argument is assuming there's a need for seasonal storage. That need would only exist if you rely exclusively on solar energy. Which of course people up north don't tend to do and people closer to the equator could actually feasibly do throughout the year. Plenty of places get by mostly powered by different combinations of renewables. E.g. Norway (wind, hydro), Iceland (geothermal, wind), Scotland (wind, tidal wave power), etc. without a lot of storage.
