  1. Minimal cost? You act like you can put hydrogen in your gas tank, hah. High pressure tanks of 700 BARS plus are expensive, bulky, can't be formed into different shapes, and still carry something like 22 liters... Then you have the cost of infrastucture. Yeah have fun going from power plant, hydrogen plant, shipping hydrogen to station, vehicle going to station, then using hydrogen. Instead of just power plant to vehicle. Hell people can use their own solar or wind to power their cars. People already have solar trailers towed by their trucks to power their vehicles while camping. Can hook up power tools to them too or use them as a generator with some of the new EV trucks. Then you have the electrical strain on the grid which will be MUCH worse. Hydrogen takes a ton of electricity at the moment to separate it from water. If people think billions of EVs will be a problem on the grid. Then Hydrogen will be double the strain at least! Batteries are rapidly progressing. Hydrogen is stuck by physical limitations by physics. There will never be a solution to hydrogens volumetric density problems, and fuel cells will never be as efficient as batteries to motors. Companies have recently made lithium air batteries. Those will be ten to fifty times better then the batteries we have today. Solid state batteries are coming out this year. Batteries will become quicker to charge, be more power dense, lighter, and safer. There is no real infrastructure for hydrogen, and there will probably never will be. It will be a niche product. Which sucks. I wanted hydrogen to succeed. Until I learned the physical limitations, and theoretical limits. I still cross my fingers for some science break through with space age magic nano tech. Fun fact about hydrogen. Water holds more hydrogen in a given volume by a ton compared to just pure liquid hydrogen! Doesn't make sense.
