White Hydrogen Challenges Green Hydrogen's Stalled Ambitions

The primary hurdle for green hydrogen has been the economic inefficiency of using renewable energy to produce it, often at a higher cost than traditional fuels. In contrast, white hydrogen exists as a raw resource waiting to be tapped. Research from the University of Oxford, Durham University, and the University of Toronto suggests that the Earth’s continental crust contains hydrogen energy equivalent to roughly 170,000 years of current global oil consumption.

Extracting this resource requires identifying specific geological traps capable of accumulating hydrogen over time. Chris Ballentine, lead author of the Oxford study, compares the discovery process to cooking a soufflé, noting that success depends on precise conditions including migration pathways and reservoir formation. Startups like Vema are already exploring these global deposits, aiming to prove that geologic hydrogen can be harvested at scale. If geologists can refine their extraction methods to mirror the efficiency of oil systems, this untapped energy could provide a commercially viable fuel source for emissions-intensive sectors like steelmaking.
