The future of hydrogen energy utilization in the chlor-alkali industry can be expected

"In recent years, the chlor-alkali industry has gradually increased its attention to hydrogen energy
.
With the development of new energy and the country's emphasis on hydrogen energy, hydrogen emissions in the chlor-alkali industry have been further reduced, and the utilization methods and channels are also expanding
.
Zheng Jiebin, deputy secretary-general of the China Chlor-Alkali Industry Association, said
in a recent interview with reporters.

According to Zheng Jiebin, after years of development, many enterprises in the industry have achieved good results
in the use of hydrogen energy with high added value according to the characteristics of the development of their regions.
They are trying to adapt to their own development models in all links of the industrial chain such as hydrogen production, hydrogen transportation, and hydrogen use, and constantly break through the bottlenecks
of hydrogen-related equipment and technology.

In the use of hydrogen energy, the practices of relevant companies in the industry are remarkable
.

Binhua Binhua Hydrogen Energy Company has realized the full ecological construction
of hydrogen energy led by "blue hydrogen" and "green hydrogen".
In recent years, they have successively developed chlor-alkali hydrogen purification technology with independent intellectual property rights and built a 10,000-ton compressed power hydrogen plant; It will also build a 10,000-ton liquid hydrogen production base in Beihai; In Zhenhua, a new energy demonstration base
integrating wind and solar renewable resource power generation and hydrogen liquefaction will be built.

Shandong Dongyue Future Hydrogen Energy Company has been committed to promoting the process of technological autonomy of domestic hydrogen energy and fuel cell industry, and has achieved mass production of the whole industry chain of perfluorinated proton exchange membrane, and the performance of fuel cell membrane products has also reached the global advanced level
.

On the basis of the original hydrogen compression device, Hangjin Chemical Company has built a new 3000 standard cubic meters / hour high-purity hydrogen filling station project, and the product purity can reach 99.
999%.

In addition, Jiahua Energy continues to promote the extension of its own hydrogen energy industry chain, develop new energy application related businesses including hydrogen energy storage, hydrogen power generation, and other energy storage, and lay out new hydrogen energy storage power stations
with distributed clean energy.

The hydrogen filling system of Qilu Petrochemical Company can send tens of millions of cubic meters of hydrogen every year; During the "14th Five-Year Plan" period, the development of the whole hydrogen energy industry chain will be regarded as the core business
of new energy development.

Statistics from the China Chlor-Alkali Industry Association show that in 2021, the hydrogen production capacity of China's chlor-alkali industry will be 1.
13 million tons, and the total amount of by-product hydrogen will be 970,000 tons
.
Although the by-product hydrogen of the chlor-alkali industry accounts for a relatively small proportion of the total domestic hydrogen sources, among the sources of all industrial by-product hydrogen, the output of chlor-alkali by-product hydrogen is not only considerable, but also the source is relatively stable
.
In addition, caustic soda by-product hydrogen is relatively pure and is one of the
ideal hydrogen sources for fuel cells.

"However, regional differences in the use of hydrogen energy by enterprises are more obvious
.
" Zheng Jiebin said that the main use of hydrogen resources in the chlor-alkali industry is divided into three
types: self-consumption, export and emptying.
From the distribution characteristics of the chlor-alkali industry, the western region is mainly produced by caustic soda supporting polyvinyl chloride, hydrogen is mainly used as raw material, and the amount of surplus hydrogen is limited
.
The local conversion rate of hydrogen in the eastern region is high, but due to the large production capacity and relative concentration, the hydrogen surplus is relatively large
.
Most enterprises in the southern region do not have major hydrogen-consuming products, but the southern region is also a region with relatively full utilization of hydrogen energy, and the demand for hydrogen energy is large
.

In Zheng Jiebin's view, the overall and rational use of hydrogen energy is the key
.

"From the current situation of hydrogen energy utilization in the chlor-alkali industry and the development trend of the hydrogen industry, industry enterprises still need to do a lot of work
to develop and utilize hydrogen energy.
" Zheng Jiebin emphasized
.
Under the "dual carbon" goal, the industry level and the enterprise level should improve the understanding and attention to hydrogen energy, coordinate hydrogen sources, rationally use and allocate limited hydrogen resources, seize the opportunity of hydrogen energy development, find the best combination of chlor-alkali industry and hydrogen energy development, promote the transformation of the chlor-alkali industry from traditional energy-consuming industries to new energy industries, and help the chlor-alkali industry achieve green and low-carbon development
