'There is enough natural hydrogen underground to meet all demand for hundreds of years', says US government agency

There are trillions of tonnes of naturally occurring hydrogen in underground reservoirs, a tiny percentage of which would meet all the world’s H2 needs for hundreds of years, geologists said last week — arguing that a “gold rush” to exploit reserves is about to start.

An unpublished report from the US Geological Survey (USGS) — an agency of the US government — has found that there are as much as five trillion tonnes of natural hydrogen underground, USGS researcher Geoffery Ellis told a US conference last week, according to the Financial Times.
