Because it’s cheaper to pull it from fossil fuels.
At present, approximately 96% of global hydrogen production relies on fossil fuels, contributing to substantial emissions, while only 4% comes from water electrolysis. Green hydrogen, produced via electrolysis with 55–80% efficiency, remains expensive at $2.28–7.39/kg, compared to grey hydrogen at $0.67–1.31/kg, which generates 8.5 kg CO₂ per kg of hydrogen production.

If you were Shell or BP would you spend billions developing new production facilities to split Hydrogen off stuff or use your existing multibillion euro fossil fuel production facilities?

As solar and wind power becomes more popular so does green hydrogen because it’s a good place to dump excess production when no other storage is available.
