Geologic hydrogen, also known as natural or “white” hydrogen, is hydrogen that occurs naturally on Earth, as opposed to hydrogen produced in a lab or in industry. The “white” hydrogen designation distinguishes it from hydrogen produced from renewable energy sources through the electrolysis of water (green hydrogen), and hydrogen obtained from fossil sources (grey, brown,
Hydrogen can be produced via several methods, and each method is typically associated with a different “color” label. The color serves as an easy way to understand the method and its environmental impact. Here are the most commonly discussed: It’s important to note that these colors aren’t universally agreed upon and some sources might use
Green hydrogen and blue hydrogen are terms that refer to how the hydrogen is produced, with each method having different environmental impacts. Both blue and green hydrogen have the potential to play significant roles in a future low-carbon economy, but their viability depends on various factors, including the availability of low-cost renewable energy for green
