![]() Hydrogen is used as a raw material for production of ammonia, methanol, hydrogen peroxide, polymers, and solvents. The stored hydrogen can be distributed through various channels to be applied to a broad range of decarbonization applications - from reducing transportation fuel emissions to help lower the carbon footprint traditionally carbon intensive industries. Excess renewable energy can be used to produce hydrogen which in turn can be stored in bulk quantities for use later or in different locations. This is particularly attractive in supporting the variable nature of energy produced from wind and solar power. The cells are used for powering cars, buses, trucks, rail, ships and planes or stationary power needs via back-up power. In fuel cells, hydrogen is the energy source. Hydrogen as part of the manufacturing process of tradition fuels helps make them more sustainable by reducing the atmospheric pollutants (SO X) associated with the use of those fuels. ![]() This hydrogen is categorized on the color scale as green. Combined with low-carbon power, electrolysis can be used to produce hydrogen without any carbon emissions. Electrolysis splits water into its components producing hydrogen and oxygen. When the energy for liquefaction of hydrogen uses power derived from renewable energy sources like wind turbines, solar panel arrays or hydro-electric facilities in combination with electrolysis, there is no emitted carbon dioxide from the electricity production. When the carbon dioxide produced is captured and stored this results in hydrogen with lower carbon intensity and is identified as blue hydrogen. In the industry, hydrogen produced from natural gas or petroleum where the carbon dioxide emissions are not captured is referred to as grey hydrogen.Ĭonverting natural gas into hydrogen and carbon dioxide through traditional SMR but in combination with carbon capture or sequestration provides the potential for lowering the CO 2 emissions. Carbon dioxide is emitted during the production process leading to a carbon footprint for the hydrogen produced. Conventional steam methane reforming (SMR) where natural gas is separated into its components is a mature, efficient and reliable production resource. ![]()
