What is the substance identification of hydrogen?
What is the ADR classification of hydrogen?
Why is hydrogen an efficient fuel for transportation such as fuel cell vehicles?
Hydrogen has the highest combustion energy per pound relative to any other fuel, meaning it is more efficient on a weight basis than fuels used currently. Hydrogen offers 2-3 times more energy than most other common fuels. It combines readily with oxygen, releasing considerable energy as heat.
Why is hydrogen the cleanest fuel?
Unlike carbon-based fuels, hydrogen produces no harmful by-products upon combustion. Only energy and clean water are produced when hydrogen is combined with oxygen in a fuel cell.
