Yeah, one doesn't have to look very deep into natural gas production and use to see that it is no less fraught with problems and environment issues equal to coal, nuclear, oil and all of it's refined products. It's being sold as a better alternative because there is money in it for someone.
IMO the only viable (long term) way to feed fuel cells is with electrolysis produced hydrogen from renewable electricity. A stationary fuel cell would not cause water usage issues since the almost pure water exhaust could easily be captured and put to use.
Like PV1 stated, all this stuff needs to be left where we found it period! Getting that done is like turning a super tanker by spraying one side of the bow with a squirt gun!
Fundamentals have to shift dramatically to save ourselves and our ecosystem. Economics has to learn to celebrate stagnate, sustainable success instead of constant growth. We need the global population to be 2 billion or less, going forward. The good of the people and the eco system has to be first and foremost in every corporate and political decision (globally). We are light years away from such a society. One that could survive and thrive in the long term. Fuel cells could be a very useful tool to such a society! In this one that we live in??
