For all intents and purposes, green hydrogen basically doesn’t exist.

As of 2021, green hydrogen accounted for less than 0.04% of total hydrogen production.[6] Its cost relative to hydrogen derived from fossil fuels is the main reason green hydrogen is in less demand.[7] For example, hydrogen produced by electrolysis powered by solar power was about 25 times more expensive than that derived from hydrocarbons in 2018.[8]
