Ask a QuestionSearch for Hydrogen Questions - Page 1 of 1


I have am researching using hydrogen to help with fuel economy and trying to figure out if it really works. The site I have looked at the most is water4gas.com. I am getting 15 mpg on my Tahoe and trying to find something that will improve the mpg. Can you please help? Thank You
Your web page highlighted news about Shell in CA opening a Hydrogen fueling station. Question: When will Honda start offering the FCX Clarity for general availability in the US? Obviously you only need Hydrogen filling stations where Honda is selling its vehicles.
