Hydrogen generated from the wall socket is around four times less efficient. You are using wall electricity to produce two gasses (one is thrown away - oxygen) and additional energy is used to compress and store that extremely light gas. Going right from the wall socket to the battery is just too simple for some people. Please search around this forum for many discussions on this topic. Let us know what you conclude. It's just plain madness and no, hydrogen is not making a comeback. We are at a point in the research and development cycle where all the invested money from the governments around the world must start to demonstrate progress or risk cuts in funding. Don't worry, that funding is mostly going towards the electrification of the chassis so it’s very useful research and development. I support it completely and wish them all the luck in the world. They will not however be able to compete against the quick-charge BEV. I placed my bets and we need to wait about 5 years to see who was right.

I can't figure out if all of these post our being sarcastic are not. How is using electricity to convert water to hydrogen so you can create electricity a better deal than just electricity???
Don't worry omegaman66, Jason might be playing his Colbert routine but many people still think that hydrogen is a better energy solution. Quick charge lithium-ion batteries exist and will go on sale in the next few months (see my other posts). The cost of hydrogen tanks, fuel cells, efficiency losses, etc. are enormous obstacles to overcome. Did you know that the thickness of the best carbon fiber hydrogen storage tanks that are going to be used in cars (Quantum) are more than 4 inches thick and must be certified to hold over 25,000 lbs of hydrogen?! You won't see the costs of all of the high pressure systems coming down anytime soon. I'm betting the costs of quick-charge batteries will fall faster than the costs of hydrogen systems. Place your bets. In five years we will all know who was right.
Oh, I would like people to research the storage and transportation of liquid hydrogen before making any predictions of it's widespread use. The following will give you a good taste as to what we are up against. If you think hydrogen storage is a done deal after reading this please read it again.

After reading the article you will discover that it’s not a simple process and that a given amount of hydrogen must be vented off or a dangerous situation will occur. Sending a ship of liquid hydrogen from Europe to the US would probably result in the loss of more than 25% alone! Put in all the other losses from the generation of the hydrogen and you don't have to be a PhD to realize other forms of renewable energy will be far cheaper.
Please tell us how heavy the car you are proposing is and how far this range extender is supposed to go. I will then calculate how big your trailer needs to be to hold the compressed air tanks.
I know I keep bringing it up but you keep saying compressed air will work as a range extender. The other thread already proved it's not viable.
Is that just the cost of the tank or all of the systems needed:
Do realize those tanks are over 4 inches thick of extremely expensive carbon fiber, have limited life and will probably need to be water tested every 5 years? That's what the DOD currently requires for high pressure tanks that travel on the road. Only $64 for 16 kWh? Bull$%^&. YOU ARE DREAMING... PLEASE WAKE UP.
