HHO gas is an incredible substance. When disassociated from water it results in expansion of over 1800 times and when ignited 1800mL of HHO gas reduces to just a mL of water. So what happens when you compress it for storage? It's just like pressing two opposing magnets together and then... BANG! The energy has to go somewhere.

That is why you should never compress HHO gas. Pure hydrogen, though, can be safely stored in hydrogen rated tanks like those used everyday in industrial applications and Hydrogen/PEM vehicles. That is why this product comes configured for output of either HHO or H2. There are other benefits to pure hydrogen over HHO as well. When injecting pure H2 into vehicle engines in hybrid applications, no computer, EFIE, MAP or O2 sensor changes are necessary. Just connect the power, connect the output and go!
