In fact, many believe that storage as hydrogen shows promise. There are many test plants for this right now in areas with a lot of wind and connection to the national gas grid.

The idea is that the hydrogen can then be used in existing gas power plants.

hydrogen has a relatively poor efficiency compared to battery storage electricity to store and back, and it's an highly flammable, infamously explosive gas. but it has a high energy density and it can be transported relatively well. hydrogen will find it's niche.

Hydrogen is one of many practical storage media. Many will be used, different ones favored in different places. Hydrogen is particularly suited for places with large, stable underground cavities.
