Those distinctions are all likely academically accurate and valid technological (green/black/blue/pink) distinctions. The real issue with the colors of hydrogen isn't the science or the technology. It's that the petroleum industry will use politics and the complexities to forestall alternative energy and EV, and play labelling games with hydrogen: "It's blue! We pumped all the CO2 into the ground!" Do you have any way to prove that is actually sequestered CO2, or that you actually did the sequestering? Is there independent certification and tests to make sure it isn't leaking out? "..... Look it's blue hydrogen! Don't use EVs!" It's like "Organic" food and "Sustainable" products all over again.
