A pilot well in Oman's Semail Ophiolite formation has successfully produced significant flows of natural hydrogen. The project, involving HyTerra Ltd and ARA Natural Resources, suggests that peridotite rocks can generate low-carbon hydrogen through natural water-rock reactions. Geologic hydrogen could drastically lower the cost of decarbonization. US estimates suggest natural hydrogen could be produced for under $1 per kilogram, making it significantly cheaper than both fossil-fuel-based grey hydrogen and electrolysis-based green hydrogen.
