When it arrives to renewables, the huge issue is: How do we shop all that power for use later on on? Since these kinds of power is intermittent in nature, storing it when there is a surplus is crucial to guaranteeing a continuous supply—for rainy times (virtually), at night time, or when the wind doesn’t blow.
Applying today’s lithium-ion batteries for lengthy-term grid storage is not possible for a number of causes. For instance, they have fastened cost capacities and really do not keep cost properly about extended durations of time.
The remedy, some propose, is to shop power chemically—in the kind of hydrogen fuel—rather than electrically. This involves utilizing products named electrolyzers that make use of renewable power to break up h2o into hydrogen and oxygen gasoline.
