> extracting hydrogen from natural gas & storing the carbon

This is what's promised. In practice it turns into "extracting the hydrogen and dumping the CO2 into the atmosphere". There are very few operating CCS schemes.

That might still be a net win for the environment, if (A) the efficiency of the end-use is higher (eg, fuel-cell cars) or (B) even 'grey' hydrogen could help solve the chicken/egg dilemma of hydrogen infrastructure while we're waiting for the price of 'green' hydrogen to come down.

To ensure that the fossil hydrogen is 'blue' and not 'grey,' we'd need carbon tax or some other legislative action.
