When it comes to renewables, the huge query is: How do we retailer all that vitality for use afterwards on? Since these kinds of vitality is intermittent in character, storing it when there is a surplus is key to making sure a continual supply—for rainy times (basically), at evening, or when the wind does not blow.
Applying today’s lithium-ion batteries for extensive-term grid storage isn’t feasible for a number of good reasons. For illustration, they have fixed charge capacities and really do not maintain charge nicely over extended intervals of time.
The answer, some propose, is to retailer vitality chemically—in the sort of hydrogen fuel—rather than electrically. This involves applying products called electrolyzers that make use of renewable vitality to split water into hydrogen and oxygen gasoline.
