Science and Technology Daily, Beijing, November 16th (Reporter He Liang) On November 16th local time, at the site of the 27th Conference of the Parties to the United Nations Framework Convention on Climate Change held in Sharm El Sheikh, Egypt, China Corner held a A side event titled "New Developments in Carbon Capture Utilization and Storage (CCUS) in China".
At the meeting, "China Coupling CCUS Hydrogen Production Opportunities (Report)" (hereinafter referred to as the report) was officially released.
The report shows that China's hydrogen production will be about 33 million tons in 2020, accounting for about 30% of global production. About two-thirds of China's hydrogen production comes from coal-to-hydrogen plants, and the hydrogen production industry emits a total of 360 million tons of carbon dioxide. China has become At present, it is the only country in the world that uses coal to produce hydrogen on a large scale.
For hydrogen to contribute to China's goal of carbon neutrality, shifting the hydrogen production process to lower emissions is critical, the report states.
China's energy resource endowment is "rich in coal, short of oil, and low in gas". In areas with abundant coal resources, good carbon dioxide storage conditions, and limited renewable energy, the coal-to-hydrogen technology coupled with CCUS will be a low-cost production The option of low-emission hydrogen can also drive the development of carbon dioxide transport and storage infrastructure.
According to the report, according to the forecast of the China Hydrogen Energy Alliance, by 2030, China's hydrogen energy demand will increase to 37 million tons, and in 2060 the demand will exceed 90 million tons.
Moreover, many coal-to-hydrogen plants in China will be built in the near future, and the installation of CCUS will play a key role in reducing emissions in these plants.
The report states that capturing carbon dioxide and hydrogen are key feedstocks for future synthetic fuels.
Although currently more expensive to produce, synthetic fuels are one of the few options for reducing emissions in long-distance transportation, especially aviation.
In addition, China's capture of carbon dioxide can also be used for enhanced oil recovery, production of chemicals and construction materials.
It should be noted that in some uses, CO2 may be re-released into the atmosphere (including synthetic fuel combustion emissions), so the emission reduction needs to be determined through rigorous accounting.
It is understood that the report was compiled by the International Energy Agency in cooperation with the China Agenda 21 Management Center, China National Energy Group, and Beijing Institute of Technology.
The report also discusses the current status of hydrogen energy and CCUS development in China, and analyzes the potential evolution of hydrogen demand in various sectors of China's economic and industrial sectors by 2060.
