When it arrives to renewables, the major concern is: How do we retail store all that power for use afterwards on? Because this sort of power is intermittent in character, storing it when there is a surplus is essential to making certain a steady supply—for wet days (literally), at night, or when the wind doesn’t blow.
Applying today’s lithium-ion batteries for very long-time period grid storage is not possible for a range of reasons. For illustration, they have set cost capacities and never maintain cost perfectly more than prolonged intervals of time.
The alternative, some propose, is to retail store power chemically—in the sort of hydrogen fuel—rather than electrically. This requires employing equipment termed electrolyzers that make use of renewable power to split drinking water into hydrogen and oxygen gasoline.
