When it comes to renewable energy, hydrogen is hailed as a pivotal resource in the zero-carbon game plan. Hydrogen energy is accessible, produces lower greenhouse gas emissions and can use existing gas infrastructure to power electricity and heat, produce other gases and fuels, and more. Recently, a “new” type of hydrogen—has captured the attention of climate scientists. Natural hydrogen—often referred to as gold hydrogen—stands apart from other, more established types of hydrogen, which require extraction and expensive maneuvering to produce. Natural hydrogen exists underground in its pure form (i.e., it’s not combined with other molecules). Estimates vary, but some researchers suspect that Earth holds as much as five million megatons of hydrogen beneath our feet. Extracting just 2 percent of that supply, in theory, has the potential to get us to net-zero emissions for 200 years.
