WebApr 10, 2024 · Energy density is a measure of how much energy a fuel source contains per unit of volume or mass. Oil and gas are pretty dense energy-wise, making them an attractive option. Hydrogen, on the other hand, has a high energy density per unit of mass, but its density per unit of volume is quite low. This means that storing and transporting hydrogen … WebIt’s the result of hydrogen ions — that is, protons — reacting with oxygen in a process accelerated by a catalyst within the fuel cell. Filling up by the kilo instead of by the liter For cars, the rule of thumb for energy content is that one kilo of hydrogen will give a range of 100 kilometers. hill and wood funeral home charlottesville
