There are several color-coded ways we produce hydrogen. Currently, the main issue is that hydrogen extraction techniques are energy-intensive.
Here are the principal types of hydrogen and how they are produced:
Brown or black hydrogen comes from burning coal in a process called gasification.
Gray hydrogen is produced when burning natural gas without any other emissions captured.
Blue hydrogen comes from the same process as gray, called steam methane reforming. The difference with blue carbon is that its carbon dioxide and other emissions are captured.
Pink hydrogen is a byproduct of the steam processes at nuclear power plants.
Green hydrogen means hydrogen extracted from water via electrolysis using renewable energy sources like Virgin games Casino rewardsSolar Energy, wind power, or hydropower.
Brown, black, and gray hydrogen production techniques release carbon emissions and methane into the atmosphere. Methane is responsible for 30% of global temperature rises. It is 82.5 times more harmful than CO2 within the first 20 years of release. It’s great to capture this hydrogen, but there’s no denying the damage the process causes.
The carbon capture associated with blue hydrogen birthed the term “clean hydrogen,” albeit studies suggest burning blue hydrogen gas for heating produces a larger greenhouse gas footprint than traditional fossil fuels like natural gas, diesel oil, or coal.  Biogas and biomass can also give off hydrogen that can be captured, stored, and used.
