You don't need to 'ride out winter'; there's a sweet spot around 100-hour storage where you can unlock a huge amount of grid resiliency and decarbonization (you can keep as many dispatchable gas plants sitting nearly-always-idle to address risk of any freak long-tail events.)

And then eventually switch over those gas plants to burn hydrogen. If they are nearly-always-idle, the amount of hydrogen needed isn't much.
