Battery Costs in Stationary Energy Could Fall by up to 66%, Grow 17-Fold by 2030, Says IRENA

Energy storage capacity to triple by 2030, if countries double the share of renewables in the world’s energy system
The cost of battery storage for stationary applications could fall by up to 66 per cent by 2030, according to a new report published by the International Renewable Energy Agency (IRENA). The falling price of batteries could stimulate 17-fold growth of installed battery storage, opening up a number of new commercial and economic opportunities, the report highlights.

Batteries are necessary for storage but a new "source of the energy stored" is needed. Cars may well be able to travel farther but using the same old sources to charge them. A good step, but not the one we really need.

Battery storage can indeed increase alternate energy resources such as solar and wind by storing energy during peak production and releasing it during off peak. There is many times more solar energy (wind is essentially from solar energy) available than we use from traditional sources. All we need is for it to be available during low wind or nighttime. Battery storage and efficient transmission such as high voltage DC transmission power lines are the greatest hold back at present. It is dumb to limit or fail to subsidize the development of renewable technologies. After we subsidize fossil fuel production!

You gave a good definition of storage tech "by storing energy during peak production and releasing it during off peak". As you are likely aware, pumped hydro storage works that way and there are numerous emerging storage technologies such as the obvious batteries and encouraging developments with new types such as flow batteries.
Molten salt, compressed air, vehicle to grid (V2G) are some other storage tech and one of the latest to emerge is abandoned mine shaft weighted storage.
This apparently works by powering an industrial motor tied to a pulley system, lifting heavy weights up to the top of the mine shaft during peak generating hours from such sources like solar/wind.
When extra energy is needed the weights lower by gravity in a controlled fashion and power a generator. Concentrated solar is used to melt mineral salts that stay hot enough to produce steam to run turbines for up to 12 hours.
All of this is great but the problem is integrating it all in to the smart grid and the absence of long distance HVDC transmission lines and dispatching the power to where it is needed.
It's always windy somewhere and extra energy from storage for off peak production is always required ,
so tying it all together and being able to transmit it instantly to where needed is essential.
On the residential/building side, net metering and roof top solar basically use the grid as their storage.
Eliminating subsidies for fossil fuels and diverting some of those funds to advanced smart grid systems and integrating these storage systems would go a long way to solving some of our concerns.
