Unlike other forms of hydrogen which involve a costly manufacturing process, natural hydrogen can be recovered with minimal additional processing and is expected to be substantially cheaper to produce.

Offering significant commercial and environmental advantages over traditional carbon-based energy sources, natural hydrogen can satisfy the demand for an economic source of zero carbon energy on a global basis.

Different processes can give rise to formation of hydrogen in the subsurface. In general, hydrogen is associated with crystalline rocks, rather than sedimentary ones. Once formed, hydrogen migrates through the subsurface until trapped by an appropriate geological trap.

As a replacement for carbon-based fuels, natural hydrogen offers significant cost and emissions advantages relative to other sources of hydrogen production because the forms of manufactured hydrogen are more expensive if produced in an environmentally sympathetic manner and depend very much on the cost of electricity.

There is no doubt that hydrogen will play a key role in decarbonising our essential, but energy-intensive, heavy industries like steel production, shipping, heavy transport and aviation. The infrastructure is already being built to facilitate these changes and governments around the world have hydrogen strategies and budgets to make it so.
