Today, hydrogen is widely used in industrial processes, but it is currently made from natural gas, which releases large amounts of CO2. Alternatively, hydrogen can also be made through electrolysis, a process which sends an electric current through water splitting the hydrogen and oxygen atoms. In the future, hydrogen produced by electrolysis will create a clean fuel for ground, sea and air transportation. Additionally, hydrogen can be stored as a clean energy carrier to prevent overloading of the electrical grid during peak times.
