Late Wednesday morning, a panel discussion was held on hydrogen as a fuel source. Hydrogen has a high heat of combustion value and this makes it a good fuel source in transportation utilizing fuel cells. Hydrogen leaves no carbon footprint.
The only problem is that to generate hydrogen, you must strip the hydrogen from methane or water, and this takes energy. In other words, you have to create a carbon foot print to avoid a carbon footprint. Methods used for obtaining hydrogen include, methane steam reforming, methane pyrolysis, and water electrolysis.
These technologies take a lot of energy usually derived from hydrocarbons. My suggestion is to use wind or solar power to provide that energy. Perhaps even use a biological process.
