A new 'Hydrogen Gold Rush' is underway in Kansas, where startups supported by investors like Bill Gates are searching for naturally occurring hydrogen beneath the earth's surface. These ventures aim to leverage clean energy sources to address climate change concerns. The Midcontinent Rift in Kansas, a billion-year-old geological formation, offers a promising location for finding hydrogen-producing rocks. Companies like Koloma and HyTerra have attracted substantial investments for their exploration efforts, with around 50 geologic hydrogen firms active globally. The potential for accessing large quantities of hydrogen presents an opportunity for a significant energy transition. Despite the uncertainties and risks involved in the exploration process, scientists estimate vast reserves of hydrogen worldwide, enough to meet demand for hundreds of years. By utilizing advanced technologies and traditional prospecting methods, these startups are increasing their chances of success. However, challenges persist in commercializing geologic hydrogen due to high production costs. The industry is working towards reducing costs to $1 per kilogram to drive widespread adoption. While the US and Australia lead in exploration activities, supportive regulatory environments and technological advancements are crucial for the success of the hydrogen industry.
