Zheng Li, et al;, report that the hydrogen production technology by wind power is an effective mean to improve the utilization of wind energy and alleviate the problem of wind power curtailment. First, the basic principles and technical characteristics of the hydrogen production technology by wind power are briefly introduced. Then the history of the hydrogen production technology is reviewed, and on this basis, the hydrogen production system by wind power is elaborated in detail. In addition, the prospect of the application of the hydrogen production technology by wind power is analyzed and discussed. In the end, the key technology of the hydrogen production by wind power and the problems to be solved are comprehensively reviewed. The development of hydrogen production technology by wind power is analyzed from many aspects, which provides reference for future development of hydrogen production technology by wind power.
In 1760s, the industrial revolution began in Europe. Fossil fuel has become the main source of energy for human beings. As human consumption of fossil fuels increases year by year, environmental problems and global warming are getting worse. With the development of energy, clean energy is gradually replacing fossil energy. In the past three energy revolutions, there is a regularity: the content of carbon is reduced and the content of hydrogen is increased, the number ratio of atoms of carbon to hydrogen is becoming smaller from coal (1:1) to oil (1:2) and natural gas (1:4), decarburization is accelerating and hydrogen content is getting larger. It has become a natural law and the trend of energy development and utilization. As a new energy of zero carbon, hydrogen energy has the characteristics of environmental safety, high energy density, high conversion efficiency, abundant reserves, and wide application. The hydrogen is zero discharge and zero pollution, and it is the most promising alternative energy source. Hydrogen energy era is an era when hydrogen was the main energy source, and it is an ideal energy time. Natural gas is used as a transitional energy in the era of hydrogen energy, and hydrogen will become the main and absolute clean energy in the future of human society.
All countries in the world regard the development of hydrogen energy as a national strategy. They make plans, depict road maps, and explore the way of industrialization. Wind power is developing rapidly as clean energy, but a large number of wind curtailment caused the waste of wind energy. It is still a topic for scholars all over the world to study. In recent years, although the issue of wind curtailment has been greatly eased the healthy and sustainable development of renewable energy has not yet fully realized.
How to solve the problem of wind curtailment has become hot spots for researchers. It is also one of the bottlenecks that restrict the sound development of the wind power industry. The technology of hydrogen production by wind power provides a new idea to solve the problem of the wind curtailment and it is important to solve the problem of wind power consumption on the spot. It is also propitious to the development of decentralized wind power generation technology and the efficient utilization of renewable energy. Hydrogen is made by electrolysis of water and stored in hydrogen storage device. On the one hand, hydrogen can be injected into the existing gas supply network as a clean and high-energy fuel to achieve complementary conversion of electricity to gas. On the other hand, it can be used directly and efficiently in high efficiency cleaning technology such as fuel cells. Hydrogen can be transformed to electric energy by fuel cell, and the electricity is transported to the power grid to improve the power quality. At the same time, hydrogen can be used as an energy carrier into the industrial and commercial fields by vehicle or pipeline, such as metallurgy, chemical industry, and other industries. And the hydrogen production system by wind power will also greatly promote the rapid development of the vehicle by hydrogen fuel cell.
