Energy Density of some Combustibles | The Geography of
Although methane and hydrogen have higher energy density than gasoline, their gaseous form creates storage difficulties. Furthermore, hydrogen must be synthesized, which requires energy. At a conversion rate of 100%, it would require 100 hours to capture the solar energy equivalent of 1 kg of gasoline on a surface of one square meter.
