WebThe production of hydrogen from natural gas or from crude oil offers no advantage over petrol. Question The electrolysis of water needs large amounts of electrical energy. Web1 day ago · Both natural gas and gasoline are based on fossil fuels. Thus, they are energy sources based on hydrocarbon chains. However, the composition of natural gas and gasoline is not the same. Natural gas has two forms- dry and wet. In dry form, natural gas is a gas that is lighter than air and in the wet form, it is liquid.

Hydrogen Fuel Cost vs Gasoline

WebGasoline. 4.4 × 10 7 J/kg. 12,000 Wh/kg = 1.3 × 10 8 J/gallon. 44 MJ/kg. Energy density is the amount of energy stored in a given system or region of space per unit volume or mass. It therefore has units of energy per length cubed or energy per mass. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg). WebWhen compressed, the density of hydrogen at 35.0 MPa is about 23 kg/m 3 and at 70.0 MPa is about 38 kg/m 3. This leads to an energy density of 767 kWh/m 3 (27°C, 35 MPa). The volume of the storage tank is the biggest challenge, since the density of compressed hydrogen is lower than that of liquid hydrogen. identity v 4th anniversary package
