"Does it take more energy to produce hydrogen than you get out of it" Yes, but that's true of all forms of storage. Hydrogen is less efficient that most forms. "does it make sense in an energy starving world" When I was young, it was "eat your food cuz the children in China are starving." Parts of the world can be gorging on energy, while other parts can be starving. If California has too much electricity, we aren't gonna be able to help the children of Africa, or even Texas, cuz they aren't on the national grid.. Right now, there are times when California produces more electricity than we can use. It's rare, and usually at night, when wind power exceeds demand, but it will occur more frequently over the next 25 years as we build out our green grid.That excess energy has to be stored, and hydrogen is one form of long-term storage.

I have an iphone and ipad. Works on both for me using Safari, and on my PC using Chrome. A few thousand kilometers of pipeline is surely enough to estimate leakage per kilometer. That can be scaled to the network expected. There's nothing controversial there, it's how projections are made. I agree with you that it's important to understand the energetics of complete cycles. I'm trying to increase my understanding, to inform myself of our options and their implications. Skepticism is good, but relentless negativism is not. Your point regarding the impact of leaked hydrogen seemed it might be important, so I googled around and found a paper that is pertinent. You said it was not worth commenting on. Dismissing a result without knowing how it was derived requires neither knowledge nor thought. That's quick and easy, but not convincing.
