Hydrogen energy storage

Hydrogen energy storage involves converting excess energy, often from renewable sources like wind or solar, into hydrogen gas through a process called electrolysis. This hydrogen can be stored safely in tanks or underground facilities. When energy is needed, the stored hydrogen is either used directly in fuel cells to produce electricity or combined with oxygen to generate power, emitting only water as a byproduct. This method offers a way to store large amounts of energy for future use, helping balance supply and demand and enabling the integration of renewable energy into the grid efficiently.
