Over the past two years, the natural hydrogen sector has witnessed an influx of hundreds of millions of dollars and significant interest from startups. However, despite this substantial investment, concrete commercial breakthroughs remain elusive. This gap between expectation and reality presents a core tension in the field, prompting critical analysis and reassessment of current methods and assumptions. Based on the serpentinization hypothesis, the predominant exploration method posits that natural hydrogen forms through the reaction of water with specific rocks in the Earth’s crust. Despite the development of supporting lab experiments and mathematical models, this theory lacks validation through the commercial…
