How does the energy from hydrogen compare to other fuels?
Hydrogen is the lightest element occurring in nature and contains a large amount of energy in its chemical bond. Hydrogen has the highest energy to weight ratio of all fuels: 1 kilogram (kg) of hydrogen has the same amount of energy as 2.1 kg of natural gas or 2.8 kg of gasoline. Hydrogen burns in air at concentrations in the range of 4 to 75% percent by volume (methane burns at 5.3 to 15 percent concentrations by volume). The highest burning temperature of hydrogen is 2,318 Celsius and is reached at 20 percent concentrations by volume in air. • How many BTUs are in one cubic foot (cf) of hydrogen? Low Heating Value: 290 BTUs per cubic foot. High Heating Value: 343 BTUs per cubic foot. • At what temperature does hydrogen liquefy? Hydrogen becomes liquid at -423 F. • How many protons and neutrons does hydrogen have? 1 proton 1 electron 0 neutrons • How was hydrogen named? Hydrogen was named by Antoine Lavoisier in 1783. A Frenchman, he called it hydrogene, naming it after the Greek word
