Main advantages of hydrogen energy development and application
From the perspective of energy security, hydrogen can be produced from water as raw material, has abundant reserves, and can theoretically be recycled; at the same time, using wind power and photovoltaic water electrolysis to produce hydrogen can solve the problem of abandoning wind and light, thus further promoting Application of renewable primary energy sources such as wind power and photovoltaics.
From the application point of view, hydrogen energy is a high-quality secondary energy that can be used as a substitute for gasoline, diesel and other energy sources, and complements lithium power batteries.
(1) Compared with gasoline and diesel, the combustion or electrochemical product of hydrogen is only water, and there are no carbon emissions and pollutants; at the same time, hydrogen has a higher mass energy density.
(2) Compared with lithium electric vehicles, hydrogen-powered fuel cell vehicles have longer battery life, can be refilled quickly, and have no charging pain points.
In terms of transportation, various countries are actively promoting hydrogen fuel cell vehicles, which have begun to take shape. Hydrogen vehicles are gradually penetrating into the commercial vehicle field; they are also expected to be substituted in the aviation and shipbuilding fields in the future.
In terms of construction, it mainly includes natural gas hydrogen-doped transportation, fuel cell combined heat and power generation, etc. In the future, hydrogen is expected to gradually replace natural gas in gas and heating, and provide some electricity for households.
In terms of electricity, hydrogen can be used as a medium for electric energy storage. In the future, it is expected to be used for long-term energy storage, or to participate in global transportation and trade to realize the regulation of electric energy in time and space.
