Renewable energy is taking off at exponential rates, putting global clean power "in line with ambitious net-zero scenarios." A new report suggests fossil fuel demand in the energy sector has already peaked, and "will be in freefall" by 2030.
Renewables surprisingly “on track” to meet net zero by 2050::undefined
HVDC links between countries will also make renewable energy transmissible to places around the globe that need it, so sun shinning in one country can be transmitted to where the demand is.
Couldn’t we pump water into dams during times of surplus and then drain the dams for hydroelectric when needed? Is that not feasible at scale?
The US (which is where I assume you are), has the second largest one in the world in current operation:

Short answer, it scales fine.
Now you need to find someone to pay for it.
The gas industry doesn’t likes this
Not everywhere has the geography to dam and use water like so. But there’s other non-lithium energy storage methods in the works.
Off the top of my head, concrete blocks, compressed air, liquid metal batteries, heat batteries, and flywheel based energy storage.
There’s more too, if you’re curious.
