In the pursuit of green energy, storage is needed for 2 reasons:

  1. To smooth out the intermittency of solar and wind power.
  2. To store energy in electric vehicles.

Note: This page does not include thermal energy storage.

Types / Candidates

Type Status
Sodium-ion batteries Good potential / needs investment.
Sodium-sulfur batteries Good potential / needs investment.
Hydrogen gas Okay for some applications, but too lossy & platinum-intensive for others.
Lithium ferro phosphate batteries Okay if used in moderation. A bit too lithium-intensive to be a general solution.
Lithium-ion batteries (NMC/NCA type) Not scalable enough: Too cobalt-intensive.
Lithium-sulfur batteries Can't handle enough charge cycles.
Lead-acid batteries Toxic / hazardous.
Stationary storage only (power grid, not vehicles)
Iron redox flow batteries Good potential / needs investment.
Compressed air ?
Pumped hydro Only viable in rare geographical locations.
Flywheels ?
Gravity blocks Not viable: Outrageously high environmental footprint of construction.

For more details, read the wikipage of each energy storage type. Links are in the table.

So far, sodium-based batteries seem to have the most hope of being a widespread solution - along with iron-based batteries for stationary energy storage.
