In recent days, Hegang has achieved the world’s first 1.2 million ton hydrogen metallurgy demonstration project (hereinafter referred to as the hydrogen metallurgy demonstration project), achieving safe and smooth continuous production of green DRI products. At present, the metallization rate of DRI products has reached 94%, and the key indicators have fully met the qualified product standards. It can be used as a high-quality and clean raw material for high-end material manufacturing, and is an important raw material to replace electric furnace scrap, especially high-quality scrap. This marks the complete success of the first phase of the project, becoming an important milestone in the transformation from traditional «carbon metallurgy» to new «hydrogen metallurgy» in the history of Chinese steel and even world steel.

The report of the 20th National Congress of the Communist Party of China pointed out that «based on China’s energy and resource endowment, we must adhere to the principle of first establishing and then breaking, and implement the carbon peak action in a planned and step-by-step manner.» In the trend of global energy towards clean, low-carbon, and intelligent development, the steel industry, whether in terms of energy structure innovation or process structure innovation, hydrogen energy application is the best way to achieve low-carbon or even «zero carbon» emissions.
As a pioneer in the green transformation of the steel industry, Hegang is committed to working alongside the national «dual carbon» strategy, deeply cultivating the integration, innovation, and coordinated development of hydrogen energy and steel, leading the research and development of global hydrogen metallurgy technology, and collaborating with well-known enterprises such as Tenon in Italy to establish a hydrogen metallurgy demonstration project.
This project plays a significant leading role in breaking through the core key technologies of hydrogen metallurgy and promoting the transformation and upgrading of China’s steel industry, providing a new path and creating a new scene for China’s steel industry to «break away» from its deep dependence on traditional fossil fuels such as coal.

The Hegang Hydrogen Metallurgy Demonstration Project breaks the conventional method of using natural gas to prepare reduction process gas internationally, and pioneered the «coke oven gas zero reforming shaft furnace direct reduction» process technology. It fully utilizes the advantages of rich coke oven gas resources and innovatively uses coke oven gas as the gas base. As a hydrogen energy source that can be directly utilized, coke oven gas contains 55% -65% hydrogen gas, which can be catalytic cracked into CO and H ₂ in a hydrogen based vertical furnace, achieving «self adjustment». After self adjustment, the hydrogen to carbon ratio in the process gas can reach over 8:1, making it the highest hydrogen content gas based shaft furnace direct reduction process in industrial production and the closest to the future 100% hydrogen reduction process state. At the same time, the hydrogen metallurgy demonstration project of Hegang has optimized the design of the shaft furnace reactor for high proportion hydrogen content, reserving the green hydrogen switching function. Industrial experiments can be directly carried out to switch to higher proportion hydrogen rich reduction gas or pure hydrogen as raw gas without large-scale transformation, providing a foundation for the future implementation of 100% green hydrogen direct reduction in the shaft furnace.

In addition, Hegang has also developed an internationally leading «CO ₂ capture+CO ₂ refining» technology, forming a green short process process that includes 30 hydrogen metallurgy patented technologies such as «Full Oxygen and Rich Hydrogen Low Carbon Reduction Melting Ironmaking System and Ironmaking Method» and «Gas Based Direct Reduction Ironmaking Method and System for Controlling Nitrogen Enrichment», creating a scalable A replicable «zero carbon» hydrogen production and innovative development model that complements the development of the hydrogen energy industry.
According to calculations, compared to the traditional «blast furnace+converter» long process process with the same production scale, the first phase of the hydrogen metallurgy demonstration project at Hegang has

On May 25th, Unit 6 of Huaneng Shidongkou No.1 Plant successfully passed 168 hours of continuous full load trial operation. At this point, China’s first equal capacity coal-fired power substitution demonstration project was fully completed and put into operation, providing more reliable, clean, and flexible power support for Shanghai’s peak summer vacation.
As a major construction project for energy security in Shanghai, this project will build two 650000 kilowatt high parameter, high efficiency, low emission, and secondary reheat ultra supercritical coal-fired units (Units 5 and 6) in the original factory area of Shidongkou No.1 Plant, replacing four 325000 kilowatt old coal-fired units (Units 1-4). Among them, Unit 5 was completed and put into operation in December last year.

This project follows the construction concept of «efficiency, cleanliness, flexibility, intelligence, and reuse», supporting international advanced coal yard closure technology, and relying on the overall architecture of China Huaneng Smart Power Plant to synchronously carry out the construction of smart power plants. It has obtained a total of 126 patent authorizations (including 22 international patents). The project has overcome difficulties such as small construction sites within the factory area, high difficulty in switching between old and new technologies, and multiple cross operations in production infrastructure. It maximizes the utilization of resources in the original factory area and significantly reduces project costs.
It is reported that the trial operation of Unit 6 of the project shows that compared to the old unit before replacement, the coal consumption for production power supply of the new unit has decreased by about 20%, equivalent to a reduction of 220 grams of carbon dioxide emissions per kilowatt hour. The technical and economic indicators and environmental indicators of the unit have reached the best level of the same type of unit.

On May 26, the world’s first M350 offshore floating production storage and unloading ship (FPSO) «Bacalhau», jointly developed and designed by Dalian Shipbuilding and Mitsui Marine under China Shipbuilding Group, was officially delivered, realizing a major breakthrough in China’s floating production storage and unloading ship shipbuilding industry.

The «Bacalhau» floating production storage and unloading vessel is the seventh floating production storage and unloading vessel built by Dalian Shipbuilding. It is also the first cooperation between Dalian Shipbuilding and the world’s general contracting company Mitsui Ocean, as well as the world-renowned oil company Aquino, in the construction of a new floating production storage and unloading vessel.
The «Bacalhau» has transformed from concept to practice, from drawings to actual ships, fully adhering to the concept of full life cycle informatization and digital management, achieving full three-dimensional design and visual construction. It is the world’s first ultra large marine engineering project designed using the latest specifications of Det Norske Veritas, which can meet the special marine environmental conditions of Brazil, West Africa, Australia and other regions, and is suitable for oil and gas development operations in multiple sea areas around the world, And it can significantly reduce the operating costs of homeowners.

This project can be used for oil extraction, oil and gas separation, oily wastewater treatment, power generation, heating, and storage and transportation of crude oil products. It is a comprehensive large-scale offshore oil production base that integrates personnel living and production command system.
The project is classified by Norwegian Veritas, flying the Bahamian flag, and has the world’s largest volume, scale, and scale parameters. The ship has a total length of 364 meters, a molded width of 64 meters, a molded depth of 33 meters, a designed draft of 22.65 meters, a displacement of over 460000 tons, and a deck area of 17400 square meters, equivalent to three standard football fields. It can process 220000 barrels of crude oil per day, equivalent to a 10 square kilometer onshore oil and gas processing plant. Among them, the weight of the oil and gas processing upper module reaches 50000 tons, with a total of 34000 pipes on board, weighing about 4000 tons. The total length of the cable is about 800000 meters, equivalent to the straight-line distance from Dalian to Shanghai. The coating area is approximately 880000 square meters, and the construction volume of each profession is three times that of ordinary ultra large oil tankers (VLCC).

The project successfully applied various long-term anti-corrosion materials such as titanium alloy pipes, heat-resistant alloy pipes, super bidirectional stainless steel pipes, and improved fiberglass steel pipes used in fire protection systems, breaking through the challenges of welding, coating, and installation processes. It achieved that the platform only requires low maintenance in the oil field, and can meet the requirement of 30 years of non docking. There are 22 cargo oil tanks with a full load storage capacity of 2 million barrels. The operation mode of double export oil transportation is adopted, which is flexible and can meet different operational needs.
