Hydrogen energy is the most environ

Hydrogen energy is the most environmentally friendly energy. Because the product of the reaction between hydrogen and oxygen is water, it will not produce carbon dioxide and nitrogen oxides that pollute the atmosphere. If hydrogen fueled internal combustion engines replace diesel and gasoline engines, the pollution will be greatly reduced.Hydrogen energy economy can be understood as a clean economy dominated by clean energy such as hydrogen energy. It refers to making full use of the advantages of hydrogen to carry out economic activities such as R & D, production, storage, transportation, operation and management of hydrogen energy according to human needs and market. The development of hydrogen economy can partially get rid of human dependence on fossil energy and realize the sustainable development of human society.At present, hydrogen energy has not been widely used, mainly due to the high production cost of hydrogen. As we all know, water electrolysis can produce hydrogen, but it is obviously uneconomical to produce hydrogen with secondary energy such as electricity. But how can we make better use of water to produce hydrogen? Scientists have made various attempts to convert light energy into hydrogen energy through biological light signals. This requires the gene that can secrete hydrogen producing protein to be transplanted into the gene of microorganism, and then produce the hydrogen energy we need through the action of microbial light valley. In the future, hydrogen energy will be promoted in the following industries.The simple principle of hydrogen oxygen fuel cell is to directly convert the chemical energy of fuel into electrical energy without combustion. It has the advantages of high energy conversion efficiency, less pollution and low noise.It can be large or small, and it is very flexible. The earliest power generation equipment was small and expensive. It is mainly used as aerospace power supply. Now Jiaming has turned to ground application within two days. The ideal fuel of fuel cell is hydrogen because it is the reverse reaction of electrolytic hydrogen production. The main purpose of fuel cell is not only to establish a fixed power station, but also suitable for mobile power supply and vehicle and marine power supply. Therefore, it is also the twin brother of hydrogen energy utilization in the futureNow, large power stations transmit power to the power grid, and the power grid transmits power to users. However, the load of different power users is different. The power grid is sometimes peak and sometimes trough. In order to regulate peak load, the power grid often needs fast and flexible power stations, and hydrogen power generation is most suitable to play this role. Hydrogen and oxygen are used for combustion to form a hydrogen oxygen generator set. The device is a rocket internal combustion engine equipped with a generator. It does not require a complex steam boiler system. Therefore, it has the advantages of simple structure, convenient maintenance and fast startup. It can start when it needs to start or stop when it needs to stop. When the power grid is in a low load state, it can also absorb excess electricity to electrolyze water.
