Learn more about the different colors of hydrogen, including brown, turquoise, and purple.

Although purple hydrogen requires significant upfront investment due to the high costs of building a nuclear reactor, once set up, the technology offers several advantages.

Hydrogen is often categorized by colors meant to indicate its emissions, but experts said getting too hung up on color could hinder the production and adoption of hydrogen-powered equipment.

The color-coding of hydrogen, although seemingly straightforward, can obscure the complexities of hydrogen production and its end-to-end impact on the environment.

There are eight colors within the hydrogen rainbow, determined by the source it was produced from and the process used to separate it from that source.

Among various hydrogen production pathways, thermochemical water splitting -- which uses thermal energy to split water into hydrogen and oxygen -- is considered particularly promising.
