How much can a cubic meter of hydrogen lift? – WisdomAnswer
Under the same conditions, air has a density of 1.293 kg/m3. This means that at sea level on a 0ºC day, hydrogen provides enough buoyancy to lift 1.2031 kg per cubic meter, while helium can only lift 1.1145 kg per cubic meter of gas. Hydrogen, then, provides about 8% more gross lift than helium does. How much hydrogen does it take to …
