Natural gas could be part of the future carbon neutral rather than a bridge. Despite the promise of being completely replaced by hydrogen one day in the future, natural gas has proven to serve as a hydrogen carrier to facilitate efficient use of existing gas infrastructure, a multi-million dollar investment that should not be neglected in the way to be greener. An 80% / 20% methane / hydrogen mixture has been successfully tested in the UK and France, powering 100 homes and a hospital boiler without any new equipment along the pipeline or in the buildings. Perhaps our carbon neutral and hydrogen future is more closely tied to natural gas than what we initially thought. There is not doubt that natural gas will play a leading role in this new energy future.

Julio, I have a proposal that would serve as insurance, for future generations, that the idea of a "carbon-neutral" or "net-zero" future isn't merely an excuse to continue natural gas or oil extraction indefinitely: make each cubic foot of fossil fuel extraction contingent on sequestering a carbon-equivalent amount of CO2 in advance. If Chevron or Shell wants to extract another billion cubic feet of methane, require either to verifiably sequester a billion cubic feet of CO2 first.
Though it seems to be a reasonable commitment to expect of any reputable oil or gas company, I can't interest any in making it. Why?

Bob, thanks for the comment. I agreed with you, that it will be an important step on the path to a greener future, but I am not sure if the demand is willing to pay the additional cost now, if not, it will be difficult for a single company to implement it. The use of gas as a hydrogen carrier is to facilitate the massive distribution of hydrogen while the cost of the technology is reduced. We should look for achieving  100% clean energy in the not too distant future.

So are you seeing hydrogen being more useful in the short term as direct energy (in the same heating/cooking applications gas is used today) than any sort of hydrogen-to-power implementation? Obviously the latter comes with lots of energy losses so it's suboptimal, but I also wonder how much the former will act to give today's carbon-emitting gas a lifetime longer than perhaps it warrants in lieu of electrification
