Hydrogen, an abundant and carbon-free power source, could play a significant role in meeting our energy needs. Unlike oil and gas, hydrogen is virtually limitless in supply and is created by natural geologic processes deep underground. The focus on renewable energy has mainly been on wind and solar power, but scientific evidence suggests that geologic hydrogen could provide far more power than we currently require. The conditions necessary for the generation of geologic hydrogen appear to be widespread, making the potential supply “astronomical.” Big energy companies like Shell, BP, and Chevron are partnering with research institutions to study geologic hydrogen, but startups like HyTerra, Natural Hydrogen Energy, and Gold Hydrogen are already on the hunt. These companies are using drilling rigs and techniques similar to those used in the oil and gas industry to locate potential hydrogen sites. Geologic hydrogen represents a cleaner and more sustainable alternative to conventional fossil fuels, as it is continuously generated underground. It also solves the problem of intermittency associated with renewable power sources. Natural hydrogen can be produced from water and renewable power, providing a clean and dispatchable source of energy. It eliminates carbon pollution associated with making hydrogen from natural gas. The existence of natural hydrogen has been known for some time, but its discovery has been hindered by the presence of hydrogen-consuming microbes in the ground. These microbes efficiently consume the colorless and odorless gas, making it difficult to detect. However, recent findings and studies have shed light on natural hydrogen, with deposits found in places like Kansas, Yellowstone National Park, and Mali. While there is immense potential for geologic hydrogen globally, extracting it may prove challenging due to its depth or offshore locations. Despite these challenges, experts estimate that there is at least 10 million megatons of hydrogen underground, far more than the current global demand. New applications for hydrogen, such as aviation fuel and stationary power generation, will further increase demand in the coming decades. In addition to providing a cheap and clean energy source, the conditions that generate geologic hydrogen also produce valuable helium, further adding to its potential. Companies like HyTerra are actively seeking to tap into geologic hydrogen reserves and are partnering with other organizations to further their research and drilling efforts. However, commercializing geologic hydrogen and creating a market for it will require time and additional research and development. The U.S. Energy Department is considering a federal grant program to support the stimulation of natural underground hydrogen generation and facilitate commercialization. While the extraction of large quantities of geologic hydrogen may take years, it is still early days for the hydrogen fuel market beyond its industrial uses. As the market develops, the demand for geologic hydrogen is expected to grow, making it a promising and sustainable energy source for the future.
