The solution is not batteries but rather capacitors.
An infinite number of inexpensive 10,000 mw flux capacitors wired in parallel can provide a lot of storage for non commercial energy users. Unlike batteries, flux capacitors can be stacked vertically. In parallel stacks of great height, little real estate is required. Thus in cities where property is expensive, multistory flux capacitor stacks can be spaced at intervals to supply multifamily residential needs.
Large capacitors are quite amazing... the problem is that they have only about 15% of the energy density of lithium based batteries. But of course, as the author of the article clearly demonstrates lithium based batteries are also not a credible solution for the lunacy related to trying to use solar and wind as our society's primary source of electrical power.
The cost per kWh of storage for super capacitors for energy storage is currently around $10,000. The cost per kWh of storage for a lithium based batteries is estimated to be around $250–$1,000 for a large storage facility. (The $250 figure is highly optimistic) The cost per kWh of storage using water pumped into a reservoir and then using it to power generators later is estimated to be around $105 per kWh. All three of these alternatives are cost prohibitive and have disadvantages not mentioned.
The "solution" is to keep the status quo (coal and natural gas) while trying to bring new forms of power generation such as thorium reactors on-line. China is currently the leading actor in bringing this technology to fruition, but other countries are working on developing this energy source as well.
Normally the left is always lined up against any type of nuclear power, but I have to wonder if the effectiveness of nonstop "climate change" propaganda may be softening their resolve.
