RE:Green Hydrogen Potential This video is nonesense and is full of misleading information. If you are actually interested in facts about hydrogen use check out The Hydrogen Science Coalition

You cannot use existing natural gas piping to transport pure hydrogen (known fact). Blending hydrogen into natural gas for home heating is nonesense; huge increase in cost for consumers with minimal reduction in CO2 emissions. O&G companies are pushing this approach.
Transport of hydrogen for export is extremely difficult and expensive.
