The application prospect of hydrogen energy in electric power industry

The use of composite gas tanks can improve the pressure resistance and hydrogen storage, such as glass fiber reinforced aluminum cans, carbon fiber reinforced aluminum cans, etc., hydrogen storage pressure can reach 30MPa, hydrogen storage density can be increased to 3.9 percent by weight. However, the method of compressed hydrogen storage has safety risks such as leakage and hydrogen embrittleness, and more compression work is needed to increase the pressure in the metal tank.

Policy risk

At present, all developed countries in the world are vigorously carrying out research and pilot hydrogen power generation, and some projects have been commercialized, and hydrogen energy utilization is an important content of future sustainable development and the realization of low-carbon economy. China has also introduced a series of favorable policies in the research and utilization of hydrogen energy, and most of China's investment in the field of hydrogen power generation comes from government funds. It can be seen that the government's support is a key factor in the development of China's hydrogen energy industry.

Before the large-scale application of hydrogen energy in the power industry, there are still a series of problems such as incomplete infrastructure construction, high cost of hydrogen power generation, and safety risks in hydrogen production, hydrogen storage and hydrogen transport technologies. The above problems can not be solved overnight, so in the power industry to promote the application of hydrogen energy technology, it is best to adopt the strategy of pilot and then promotion. In particular, large-scale projects should not be carried out blindly, and feasible plans need to be formulated in advance, and scientific research institutions and power enterprises should be encouraged to participate together. Thus accelerate the industrialization of hydrogen energy scientifically and rationally.

peroration

Hydrogen energy is a renewable and clean energy, which has a broad application prospect in the power industry. The use of hydrogen generators and PEMFC fuel cells and other technical means to effectively convert hydrogen energy into electricity, not only provides a feasible way to deal with the depletion of fossil energy, but also effectively solve the environmental problems caused by excessive carbon dioxide emissions.

However, the promotion of hydrogen energy in the power industry faces the following problems: hydrogen power generation cost is high, the infrastructure is not perfect, greatly hindering the marketization process; China's grid structure foundation is weak, the grid connection is unstable, and the progress of grid planning lags behind the development speed of new energy technologies; The development of hydrogen energy technology largely depends on policy guidance, and the internal power is insufficient. Therefore, when China promotes the use of hydrogen energy in the power industry, it needs to carry out scientific planning based on the current situation in China, pilot and then promote, and actively and steadily incorporate hydrogen technology into the low-carbon economic development strategy.
