Hydrogen resources have been a significant market, with recent interest focusing on its role in the green energy transition. Natural hydrogen, a potential solution for hard-to-abate industries, is gaining attention globally. While most hydrogen currently comes from fossil fuels, efforts to produce low-carbon green hydrogen are ongoing. The quest for natural hydrogen has similarities with the search for helium, with renewed interest from countries like Australia, France, and the U.S. The infrastructure for natural hydrogen projects is less space-intensive than green hydrogen facilities and doesn't require surface water. However, lack of clear regulations in key exploration regions like the U.S., Canada, and parts of Africa hinders progress. Establishing policies like those in South Australia can boost exploration and provide valuable data for leveraging natural hydrogen's green energy potential.
