Utility-scale batteries are very vulnerable to fire
in addition to being as expensive as nuclear power plants.

My regular readers know that I often write about energy because energy is a key element in human material progress. One of my most popular articles to date was Utility-scale batteries are as expensive as nuclear power.
To illustrate the massive cost of utility-scale batteries, I focused on the Moss Landing Energy Storage Facility in Monterey California. Moss Landing is the largest lithium-ion battery energy storage system in the world. I have been there on several occasions as I have family in the region. It is massive.
The Moss Landing energy storage system consists of more than 110,000 battery modules in 122 containers. Its total capacity is 750 MW/3,000 MWh. If I understand the units of measurement correctly, the entire battery system can output 750 MW of electricity for a total duration of 4 hours (3000 / 750 = 4).
This means that even the largest battery storage system in the world:
Cannot even store enough electricity to replace a typical fossil fuel or nuclear plant (1000 MW), and
It can only approximate the output for 4 hours.
If we assume that we want to replace just one 1000 MW power plant with 12 hours of battery storage (enough for a solar plant to produce enough electricity to get through the night) then that would require 12,000 MWh of utility-scale batteries. Using Tesla’s advertised prices for Megapack, which cost $5,055,940 for a mere 19.3 MWh, then that would cost a whopping $3.1 billion.
That is more than the cost of a 1000MW South Korean nuclear reactor… except that the South Korean nuclear reactor actually produces electricity!
Update
Well, the saga of the Moss Landing Energy Storage Facility gets much worse. In addition to costing as much as nuclear power plants, it is apparently more dangerous to local residents.
On January 16, a massive fire broke out in the Moss Landing Energy Storage Facility that
Destroyed 80% of the batteries
Released plumes of smoke and hazardous gases
Forced the evacuation of up to 1500 people
So do you still think that utility-scale batteries are much safer than nuclear power plants?
More details on the fire here and here. Because of the media focus on the far larger Los Angeles wildfires, this event got far less media coverage than it deserved.

It is hard to understand just why there is still so much resistance to recognizing the down sides of renewable energy programs, given the depth of the cost/ benefit analyses that have "finally" come to light in the last decade (or two?). This of course extends to the merits and limits on battery storage to provide "backup" or temporary electricity. The analyses of hydrogen as a "fuel" rather than a form of energy transferance seem to be providing similar cautions about the limitations of hydrogen. Perhaps some breakthrough will still be found for hydrogen, however?
