Methane leakage

Natural gas that escapes during extraction, processing and transport before it reaches the plant. Because methane is a potent greenhouse gas, even a few percent of leakage can erase much of blue hydrogen's benefit. At 8 percent leakage blue hydrogen's reduction versus grey falls from about 75 to about 45 percent.
