The industry believes that the coal -based hydrogen energy will play a "bottom" role for a long time

The reporter learned from the fourth China Hydrogen and Hydrogen Energy Industry Development Conference by the China Coal Processing and Use Association, Shandong Energy Group, and the Dalian Institute of Chinese Academy of Sciences in the recently. The transition period will play a "bottom" role, transitioning from "hydrogen hydrogen" to "blue hydrogen" and "green hydrogen", and ultimately achieve low carbonization and development of hydrogen energy.

The meeting pointed out that the establishment of a hydrogen energy system is inseparable from sufficient hydrogen. In the initial creation and transition period, coal -based hydrogen energy, commonly known as "hydrogen hydrogen",, such as coal -making and industrial by -production hydrogen 2. Low -cost hydrogen energy supply network to ensure the supply of hydrogen energy demonstration applications and promotion of fuel supply.

At present, my country ’s hydrogen output exceeds 35 million tons/year, which is the world's first largest hydrogen producing country. Among them, "hydrogen hydrogen" -genal hydrogen accounts for more than 62%, and about 20%of industrial by -produced hydrogen produced; The meeting believes that although "green hydrogen" is good, the current electrolyte hydrogen -based hydrogen is consumed by 56,000 kWh and more than 20 tons of water. At the beginning of the development of hydrogen energy, "green hydrogen" does not have sufficient, low -cost, and stable supply capacity. In contrast, coal -based hydrogen energy is more likely to play the role of "bottoming" for a long time.

Although "hydrogen" has carbon emissions, the cost is low. According to the participating experts, in recent years, with the improvement of modern coal chemical technology and equipment level, the cost of hydrogen per kilogram of coal is only 10-15 yuan, which is only 1/5 to 1/4 of the cost of electrolyte hydrogen. In addition, my country's current high -temperature coke and low -order coal are used to use low temperature and heat -relieving hydrogen to produce nearly 10 million tons. If it is processed to high -purity hydrogen, it is estimated that more than 1 million heavy trucks and millions of household cars can be provided for one year for one year Hydrogen, and the cost per kilogram of hydrogen is only 7-8 yuan. my country has good conditions for the development of lignite hydrogen -making resources and mature technological routes. It can also use more than 130 billion tons of lignite in the central and eastern regions of Inner Mongolia.

Regarding the question of the "high hydrogen" of coal -based hydrogen energy, the entrepreneurial entrepreneurs pointed out that the current CO₂ discharged by the coal -based hydrogen energy is a high concentration, higher purity CO₂, and concentrated emissions, which is conducive to the harmlessness of CO₂ The use of chemical disposal and carbon circulation eliminates the carbon capture link, and the cost of hydrogen production is greatly reduced. More importantly, the green methanol (liquid sunshine) of my country CO₂ and green hydrogen coupling has been completed in China. Multiple green power -green and coal chemical coupling development demonstration projects are under construction. The demonstration of collecting sealing (CCS) project is also underway, all of which are constantly "blue" and "green" for coal -based hydrogen energy.
