Before you jump into any hydrogen technology, look very closely at what hydrogen plumbing and hook up system you need. Hydrogen molecules are the smallest of all and we found when handling it in a lab, it will migrate through (leak from) most normal gas connections. Then if you have places that trap the loose gas, you're looking at flash fires and/or explosions. Handling this stuff like LP gas is just not going to work. It take special and expensive equipment and care.
