At the second China International Supply Chain Promotion Expo held recently, new energy supplier Changying Precision exhibited the company's latest technologies and innovations in lithium batteries and hydrogen fuel cell structural parts, which attracted a lot of attention in the industry.
Hydrogen energy, as a "new star" in the energy sector, has recently appeared frequently in the public's field of vision, and in the process of realizing the "dual-carbon" goal and energy transition, hydrogen energy can completely realize zero carbon emissions.
Hydrogen energy has a wide range of uses and is highly valued in the power sector. Because wind, light and other renewable energy generation is significantly affected by weather factors, photovoltaic power generation relies mainly on solar energy, sunrise power generation is abundant, and sunset power generation is stagnant. Wind power generation is also affected by the size of the wind. Therefore, although wind and light as renewable clean energy is an important energy source in the low-carbon transition, its natural factors make power generation extremely unstable.
Hydrogen energy can adjust the instability of renewable energy generation and become a new form of energy storage through the conversion of electric-hydrogen-electricity. Electrolytic water hydrogen storage is carried out during the period of strong solar resource power generation, and the stored hydrogen is used for power generation during peak hours of electricity consumption, which can promote the consumption of renewable energy and also alleviate the pressure on electricity consumption.
So if hydrogen is so great, why hasn't it spread fast enough? It's certainly not a simple matter, and there's still a long way to go to achieve zero carbon.
As a secondary energy source, hydrogen energy, unlike traditional fossil energy sources which is difficult to obtain directly from nature. There are a number of challenges to realizing the ultimate utilization of hydrogen energy.
One of the breakthroughs is the production of hydrogen energy. Although hydrogen energy is a clean energy, its production process is not completely zero carbon, according to its production process can be divided into "gray hydrogen", "blue hydrogen" and "green hydrogen", of which only through renewable energy power generation electrolysis of water to produce hydrogen "green hydrogen" can realize zero carbon emissions. Among them, only "green hydrogen", which is produced by electrolyzing water from renewable energy power generation, can realize zero carbon emission. In the future, as the cost of renewable energy generation continues to decrease, the proportion of green hydrogen will increase year by year and is expected to reach 70% by 2050.
In addition, the core technology of hydrogen energy storage and transportation, terminal and other links also needs to be further improved. To overcome the problem of efficient and safe storage and long-distance transportation of hydrogen, and develop new storage and transportation materials and technologies. In the field of terminal application, it is necessary to continuously improve the technical system of converting hydrogen energy into electric energy, heat energy and other forms of energy, and improve the efficiency and stability of energy conversion.
At the same time, the development of the hydrogen energy industry cannot be separated from a sound policy support mechanism, a complete standard and specification system, and a mature upstream and downstream cooperation of the industrial chain. Only a multi-pronged approach can lay a solid foundation for the comprehensive popularization and efficient use of hydrogen energy.
The rapid development of hydrogen energy is an important path to help China achieve the goal of reaching the peak of carbon and carbon neutrality. With the support of national policy documents, the development and utilization of hydrogen energy is triggering a profound energy revolution, and hydrogen energy will become an important tool to solve the energy crisis and build a clean, low-carbon, safe and efficient modern energy system. Xiao Bian believes that in time, hydrogen energy will be able to break through many obstacles, be fully utilized, and completely achieve the goal of zero carbon emissions.
