When it arrives to renewables, the major query is: How do we retail store all that electricity for use later on? For the reason that these electricity is intermittent in mother nature, storing it when there is a surplus is essential to making certain a constant supply—for wet days (virtually), at evening, or when the wind does not blow.
Utilizing today’s lithium-ion batteries for prolonged-expression grid storage isn’t possible for a variety of causes. For illustration, they have fixed charge capacities and do not keep charge properly around extended periods of time.
The remedy, some propose, is to retail store electricity chemically—in the form of hydrogen fuel—rather than electrically. This involves employing equipment named electrolyzers that make use of renewable electricity to split h2o into hydrogen and oxygen gasoline.
