Explanation –

White hydrogen is a naturally occurring form of hydrogen found in underground deposits and created through fracking. It is a relatively new discovery and is not as common as other forms of hydrogen.

Both white hydrogen and green hydrogen are environmentally friendly fuels that produce no harmful emissions. However, green hydrogen is considered to be more sustainable because it is produced using renewable energy sources, while white hydrogen can be produced from fossil fuels.

White hydrogen is rare compared to other forms of hydrogen. Gray hydrogen is by far the most abundant form of hydrogen, making up more than 90% of all hydrogen produced globally.

When white hydrogen is used as a fuel, it produces water vapor (H2O) as its only emission. Water vapor is a natural component of the atmosphere and does not contribute to climate change.
