Hydrogen & Our Energy Future
molecule—each molecule has two atoms of hydrogen (which is why pure hydrogen is commonly expressed as "H. 2 "). At standard temperature and pres sure, hydrogen exists as a gas. It is colorless, odorless, tasteless, and lighter than air. Like electricity, hydrogen is an . energy carrier (not an energy source), meaning
Why are we still not seeing hydrogen cars on our roads?
Hydrogen gas is primarily obtained through electrolysis, which requires a significant amount of energy. Currently, most hydrogen is produced using fossil fuels, which defeats the purpose of reducing carbon emissions. The production of hydrogen using renewable energy sources, such as solar or wind power, is not yet commercially viable on a large

5 Reasons Why Hydrogen Cars May Never
Hydrogen electric vehicles have faster refueling times, the advantage of longer driving ranges, and the potential for greater energy storage capacity while the
Europe is going all-out on hydrogen energy. Why not
US investments in green hydrogen have been small thus far: The Energy Department announced last week that it would spend $64 million on hydrogen research and development in 2020, with $15 million earmarked
Why Hydrogen Will Never Be The Future Of Electric
The fuel cell process of converting hydrogen back to electricity is only 60% efficient, after which you have the same 5% loss from driving the vehicle motor as for a BEV.
