Less certain is how all that clean hydrogen will be produced. The two leading methods — so-called "green" and "blue" hydrogen — have gained traction, but now a third is attracting attention as well. Methane pyrolysis, sometimes referred to as "turquoise hydrogen," involves extracting hydrogen from either fossil-based or renewable natural gas streams with high heat or catalysts instead of steam. Rather than releasing the carbon byproduct as emissions, the process captures it in a solid form that has several industrial uses. Research into methane pyrolysis has picked up in the last decade or so as hydrogen has emerged as key to future decarbonization efforts.
