“Under the \"dual carbon\" goal, central state-owned enterprises leverage their respective industrial advantages to showcase their capabilities in the hydrogen production sector. Sinopec – Photovoltaic Hydrogen Production: On November 30, 2021, China’s first demonstration project for producing 10,000 tons of green hydrogen via photovoltaic technology was launched – the Sinopec Kuche Green Hydrogen Demonstration Project in Xinjiang. Once operational, this project will be able to produce 20,000 tons of green hydrogen per year. This is Sinopec’s first model project that covers the entire process of green hydrogen production and utilization, including wind and solar power generation, transmission of green electricity, production of hydrogen from green electricity, hydrogen storage, hydrogen transportation, and the refining of green hydrogen. At the same time, all major mechanical equipment and key materials have been domestically produced. The project will replace the existing natural gas-based gas production method, and is expected to reduce carbon dioxide emissions by 485,000 tons per year. Sinopec plans to establish 7,000 distributed photovoltaic power generation sites across the country in the future. The establishment of photovoltaic power stations will further reduce the cost of hydrogen production. At a cost of 0.7 yuan per cubic meter for each stage of hydrogen production, transportation, and use, the price of hydrogen will be around 2.1 yuan per cubic meter.
CNPC – Hydrogen production via electrolysis of water: On April 22, the construction of the hydrogen transport pipeline for CNPC’s demonstration project on hydrogen production using renewable energy began. Once completed, this pipeline will lay the foundation for the successful development of the 160-megawatt photovoltaic-based hydrogen production demonstration project at the Yumen oil field. The project involves the construction of a 160-megawatt photovoltaic power plant and a hydrogen production facility capable of producing 7,000 tons of hydrogen through electrolysis. It is expected to be fully operational by 2023, with an annual electricity generation capacity of 278 million kWh and the production of 7,000 tons of green hydrogen.
CNOOC – Hydrogen production from seawater and offshore wind power. China is rich in marine resources; the raw materials used for hydrogen production from seawater are inexpensive, and the quality of hydrogen produced in this way is higher. On April 13, CNOOC officially established the Beijing New Energy Branch of CNOOC (China) Co., Ltd. The main activities of this new energy branch include developing offshore and onshore wind and solar power generation, advancing research in CCUS technology, and exploring the development of hydrogen energy. Leveraging marine resources, we explore differentiated hydrogen energy technologies such as offshore wind-powered hydrogen production and integrated hydrogen storage and transportation, in order to promote the integrated and coordinated development of the oil and gas industry with the new energy industry. CNOOC also owns China’s first E-Gas coal-to-hydrogen integrated plant; as of May 7, this plant had been in operation continuously for over 270 days, producing more than 55,000 tons of hydrogen in total. E-Gas technology features high carbon conversion rates, low emissions, high heat utilization efficiency, and reduced oxygen consumption. Compared with traditional natural gas-based hydrogen production processes, it can reduce costs by 20% to 25%. Currently, only two sets of devices are in operation worldwide. CNOOC Refining has provided a mature \"Chinese solution\" to ensure the reliable operation of global E-Gas coal-to-hydrogen technology.
China Huaneng – Large-scale electrolytic hydrogen production equipment. On November 26, 2021, the world’s largest alkaline hydrogen production water electrolyzer by single-cell capacity, developed under the leadership of China Huaneng, was produced in Suzhou. It is capable of producing 1,300 standard cubic meters of hydrogen per hour; it is also the world’s first commercial alkaline hydrogen production water electrolyzer to achieve such a production capacity as well as a current density of 6,000 amperes per square meter. The commissioning of this equipment marks China’s successful mastery of the key technologies for high-performance large-scale electrolytic hydrogen production, taking a solid step forward toward large-scale production of \"green hydrogen\".
**Power Investment – Hydrogen Fuel Cells: In December 2021, **Power Investment Guohydro Technology’s production line for proton exchange membranes with a capacity of 300,000 square meters came online. At present, **Dian Tou has mastered the eight key components of fuel cells, achieving full autonomy throughout the entire process – from materials to components, to fuel cell stacks and systems. During the Beijing Winter Olympics, hydrogen buses equipped with **ETP’s ‘Hydrogen Leap’ fuel cells made a remarkable appearance, delivering stable performance with zero accidents, zero failures, and zero mistakes. This is the first time in the history of the Winter Olympics that hydrogen fuel cell vehicles have been used on a large scale as the main mode of transportation.
CRRC – Hydrogen-powered locomotives: On October 29, 2021, China’s first hydrogen fuel cell hybrid locomotive was put into service on the **Dian Tou Jin Bai Railway in Inner Mongolia. This locomotive was developed by CRRC Datong, with the **“Hyteng” fuel cell developed by PowerChina Hydrogen Energy as its core power source. With a designed speed of 80 kilometers per hour, it can operate continuously for 24.5 hours on a single unit when loaded with hydrogen, and its maximum pulling capacity on straight tracks exceeds 5,000 tons. Locomotives can carry out various tasks such as operation, shunting, and rescue at large factories, mines, ports, and other locations, without the need to modify any of the railway infrastructure. Once all lines of the Jinbai Railway use this type of locomotive, carbon emissions can be reduced by about 96,000 tons per year, which is equivalent to planting more than 6 million trees.
China Energy Engineering Group – Hydrogen-powered power generation: On December 28, 2021, the first unit of China’s first megawatt-class hydrogen-powered power station began generating electricity after being connected to the grid in Lu’an, Anhui Province. Designed by China Energy Engineering Group Anhui Institute, this project is the first in China to achieve a complete integrated system for hydrogen production via megawatt-scale electrolytic pure water separation, high-pressure hydrogen storage, and hydrogen fuel cell power generation. Hydrogen energy can achieve responses to input power on the order of seconds or milliseconds, providing auxiliary services such as peak shaving and frequency regulation for power grids, thereby enhancing the safety, reliability, and flexibility of power systems.
Three Gorges Group – Hydrogen-powered workboat: On May 17, the first domestic inland hydrogen fuel cell-powered workboat, the “Three Gorges Hydrogen Boat 1”, which was developed and built through a collaboration between Three Gorges Group’s Yangtze River Power and the 712th Research Institute of China State Shipbuilding Corporation, began construction. It is the first hydrogen fuel cell-powered workboat in China to be certified by the China Classification Society (CCS). “The “Three Gorges Hydroboat 1” catamaran can reach a top speed of 28 kilometers per hour, with a range of up to 200 kilometers. Once completed, it will mainly be used for transportation in the Three Gorges reservoir area, as well as for inspections of the reservoir area and emergency response tasks, between the Three Gorges Dam and the Gezhouba Dam. Its application in manufacturing will further promote the exploration and development of hydrogen energy technologies for inland vessels, contributing to the growth of China’s hydrogen-powered vessel industry.
The distance for Three Gorges Hydrogen Boat 1 is too long; it would be better if it were 600 kilometers – from Three Gorges to Yibin
