"Storage" is a big word. Methods of storage are not interchangeable with one another.
Think about food storage: your shelf doesn't have the same properties as your fridge, which is not the same as your freezer, which is not the same as jars in your basement. It's the same for batteries: they're good for very short periodicity, but fail at anything beyond the week. So you can't store your energy from the summer to use it during the winter, for instance.
Your point of view is one of a cornucopian (https://en.wikipedia.org/wiki/Cornucopian), hoping that it is fine to wait for better days because "surely" progress will arrive. The situation is that we don't have some time to think and wait for innovation, we're already a number of decades late. Why wait for something that might or might not happen, in 5, 10, or 50 years, instead of doing what already works today ?
