So, the energy is really solar & the hydrogen is simply a storage system (alternative to battery). Might be good if we can develop the infrastructure to handle & distribute hydrogen.
"And how much energy is needed to produce burnable Hydrogen? Is it a core energy like coal and nuclear? "
Good question, all the methods I have seen to produce H require the same energy to make H you get back when you burn it. Plus hydrogen gas is hard to store or liquefy.
I also have Humana Advantage plan & am very happy with it. I had a bicycle accident with over $150,000 in bills, I paid about $1000 out of pocket because the ambulance was out of plan.
