using hydrogen for transportation is the same as saying you ate healthy because you ordered a salad at Mcdonald.

A salad in McDonalds is infinitely healthier than a large burger with fat sauce, lots of fries and a big sugary drink; in the same way that hydrogen, depending on how it's produced, could be infinitely better more eco-friendly than natural gas.

  Yes, but there are also better restaurant you can go to, so why wasting money, time and your taste to eat a mcdonald salad?

You can produce hydrogen with surplus electricity generated from wind power. Can it get any greener? In Germany Greenpeace Energy creates Methane this way and adds it to natural gas. Hydrogen would be much better IMO. Feeding wind energy to the grid was stopped for a while because there was so much of it and nuclear reactors run when they do. There is a lot of potential to be tapped.

  what you are missing is: 1. Keeping the hydrogen at high pressure requires a lot of energy. 2. Hydrogen produces H2O in gas form, which in itself it is still a greenhouse gas. 3. True, hydrogen can be produced by "green" technologies, but what is the energy lost throughout the procedure? It is quite a loss (about 20%). Moreover, it is theoretically viable to produce all electric energy via renewables, albeit impracticle and 100 years away. Thus, I can't see how saying that """EVENTUALLY""" hydrogen might be renewable is good for the environment. Hydrogen is good for a very niche part of our production system (and spoiler it is not car industry or house heating where better alternatives already exist[1][2]).
