The study's findings, which were presented at the American Association for the Advancement of Science (AAAS) annual meeting in Denver, claim that there are five trillion tons of hydrogen reserves from subterranean sources in the planet.
According to study head Geoffrey Ellis, quoted in the Financial Times, "the bulk of the hydrogen is likely to be inaccessible (for development), but even if a few percent were extracted, it would be enough to meet all expected demand - 500 million tons per year - for hundreds of years."
Reforming of gas, which is mostly made up of methane, supplies a large portion of the demand for hydrogen as a fuel and industrial raw material (used, among other things, in the manufacturing of ammonia and fertilizers). The resulting hydrogen in this instance is referred to as "blue" in the case of carbon dioxide emissions capture, and "gray" in the opposite scenario.
"Green" hydrogen is created in lesser quantities through the electrolysis of water using renewable energy sources.
