Batteries don’t have to be the traditional ones we use and think of.
They can be things like pumping water up a hill and releasing it to spin a turbine or using rocks storing heat.
The storage capacity can be added, it’s just don’t going to be banks of lead or lithium batteries
- h0l0cube 2y agoAnd for lithium batteries, maintaining an overcapacity drastically increases the lifetime by reducing the depth of the cycle. e.g., you get vastly more cycles at %50 DoD vs %80. This would increase the lifespan to be many decades
- kemiller 2y agoCalifornia is already planning a giant off-river reservoir that will be dependent on pumping to fill. If it could be set up to kick in instead of curtailment it could be a win win.
- nradov 2y agoThe California Environmental Quality Act (CEQA) makes it extremely difficult to build new pumped storage facilities. It's possible in principle but will take many years to get through the construction permits and inevitable lawsuits.
- _heimdall 2y agoCalifornia isn't exactly known for water management practices, though sure there are storage systems that use kinetic potential as a battery. In theory that can be used at very large scales, if the water and elevation is available for use. Is be really curious how the math works out with regards to how much water would be required for say 3 days of use in LA. That may even be an over estimate of storage needs given how few rainy days they get.
