So few details. Where is it? How deep? Can any of it be accessed?

  And how much methane will need to be released/flared in the process of accessing it? (I.e., is this basically greenwashing PR for the fossil-fuel extraction industry.)

    I ran some numbers. I think a typical "gold hydrogen" reservoir yields a mix of about 75% hydrogen and 25% natural gas, by volume. Hydrogen is much lighter, but much more energy dense, so overall, for such a mix 50% of the energy will come from hydrogen and 50% from natural gas. In other words, the CO2 emissions if you burn this mix will be cut in half. Basically, moving power plants from natural gas to "gold hydrogen" would result in the same type of emissions reductions as moving coal burning power plants to natural gas.

      Transportation might be an issue. That's why a lot of natural gas is flared and not sold – selling it is often uneconomical.
