Discussion on the Development Strategy of Coal Chemical Industry in China I: In recent years, some coal-rich provinces and regions in China have made the decision to accelerate the development of the coal chemical industry in order to transform their resource advantages into economic advantages. Affected by rising international prices for crude oil and natural gas, as well as insufficient domestic oil and gas resources and increasing oil imports, some companies are also looking forward to developing methanol fuel, and construction work on certain projects has already begun. Accelerating the development of coal chemical industry has become a hot topic in the sector. Coal chemical industry is an important part of China’s chemical industry. In the new context of the development of coal chemical industry, it is indeed a matter of great significance to the overall progress of this sector that we explore in depth its development strategies, models, and approaches in line with the requirements of the scientific development concept. History has brought us to the early 21st century; we should take a perspective befitting this era, think deeply and strategically, and pursue a path of sustainable development for China’s coal chemical industry.    I. To develop modern coal chemical industry, it is necessary to thoroughly implement China’s \"Medium- and Long-Term Energy Development Plan.\" Unlike other industrial sectors, fossil fuels—natural gas, oil, and coal—serve two functions in the chemical industry: they can be used as fuels as well as as raw materials for chemical production. There is a close connection between these raw materials and energy sources. The chemical industry is a major energy consumer, ranking second only to the steel industry. Coal chemical industry is a high-energy-consuming sector. Given the heavy energy consumption of the chemical industry, any adjustment in the energy structure or changes in supply and demand conditions (such as oil crises) have a dual impact on it, affecting the development of coal chemistry to varying degrees.    The executive meeting of the State Council approved the draft of the \"Medium- and Long-Term Energy Development Plan Outline (2004–2020)\\" (hereinafter referred to as the \"Outline\") on June 30. The outline establishes China’s energy strategy for the new era, and its introduction plays a crucial role in the production, use, and development of energy in the country. Energy is a key focus of economic strategy; it is necessary to provide a stable, economical, clean, reliable, and safe energy supply to support the comprehensive construction of a moderately prosperous society. Sustainable energy development and efficient utilization are essential to foster the sustainable economic and social progress of our country. To address China’s energy problems, it is necessary to adopt the right approach: we must start from China’s national conditions, respect the laws of nature and economics, draw on international experience, and pursue an energy development path with Chinese characteristics. To this end, the Outline requires that it be ensured that: \"Firstly, energy conservation must be given top priority; comprehensive and strict energy-saving systems and measures should be implemented to significantly improve energy utilization efficiency.\" ; Second, it is necessary to vigorously adjust and optimize the energy structure, adhering to a strategy that takes coal as the main source, electricity as the core, and promotes the comprehensive development of oil and gas as well as new energy, among other eight aspects of work.    **Interpretations of the ‘Outline’ by energy authorities state: “Optimizing the energy structure is very important.” Coal being the main source is a reality, while optimizing the energy structure is the direction. Because reality and the direction of development are two different things. Although coal accounts for as high as 70% of China’s energy mix at present, this does not mean that China’s energy structure is optimized. We use coal as a last resort, and it’s not the case that the more we use it, the better. Our focus is on restructuring. Given the actual circumstances, coal cannot be underestimated. It is worth noting that coal production capacity is not a quantity that can be increased arbitrarily. When the annual coal production reaches 2 billion tons, that is the limit. Beyond this limit, the exploitation of coal becomes more difficult, costs rise further, and sustainable growth becomes nothing but an empty phrase. At present, the structure of global primary energy consumption is dominated by high-quality energy sources such as oil, natural gas, and nuclear power. In China, however, 75% of energy consumption comes from coal, about 17% from oil, about 5% from hydropower, while natural gas and nuclear power account for around 0.4% each. In China’s energy structure, inefficient and highly polluting energy sources such as coal, coke, and straw account for a significant proportion, while efficient and clean energy sources such as electricity, oil, and natural gas make up only a small share. Such a structure not only leads to substantial energy waste but also causes severe environmental pollution. Our country is one of the few in the world today whose energy structure is based on coal, far from the global trend toward an energy structure dominated by oil and gas. In the future, our country will accelerate the optimization of its energy structure by increasing the share of clean and renewable energy, but the current reliance on coal-based energy is unlikely to change in the long term. In the second half of this century, humanity will face the problem of depleted oil resources, forcing it to turn to natural gas as the fourth generation of primary energy sources (biomass based on wood, coal, and oil belong to the first, second, and third generations of energy sources respectively). According to available data, even if natural gas’s share in global energy consumption rises from 26% to 40%, it could still be used for another 70 years. The growth rate of global natural gas production is expected to rise, with its role in the energy sector becoming increasingly prominent. China’s natural gas industry has entered a period of rapid growth. By 2020, China’s natural gas production is expected to rise from the current level of 34 billion cubic meters to 120 billion cubic meters, while demand is set to increase from over 30 billion cubic meters to around 200 billion cubic meters. The supply gap will be approximately 80 billion cubic meters. By then, the share of natural gas in the primary energy mix will rise from 3% to around 10%, making it the third-largest source of energy in our country, after coal and oil.    Affected by the shortage of oil and gas resources, our country relies more on imported oil. Since 1993, China has been a net importer of oil for 11 consecutive years, with import volumes rising sharply. In 2003, the import volume of crude oil and refined oil exceeded 100 million tons. In 2003, 252.32 million tons of crude oil were consumed, and 169 million tons were produced, resulting in a self-sufficiency rate of 67% ; Fuel oil self-sufficiency rate: 46% ; With a LPG self-sufficiency rate of 68%, China has become the world’s second-largest oil consumer and the seventh-largest oil importer. It is estimated that China’s oil demand will exceed 300 million tons by 2010, and reach 420 million tons by 2020. If China relies on its oil reserves to maintain the current level of production capacity, the degree of assurance provided by domestic resources will be less than 60% by 2010, and only 42% by 2020. The overall supply situation of petroleum products in our country is becoming increasingly strained, which has become a bottleneck for economic development. The reliance on foreign sources is rising year by year, posing a threat to our country’s economic security.    China is rich in coal resources, which play a dominant role in its energy supply. But overall, the sulfur content is high, and high environmental protection standards are required for its development and utilization. In 2003, China’s coal production reached 1.65 billion tons, an increase of 15% compared to the previous year. As China’s economy continues to rely on extensive growth patterns, coal production and transportation are under increasing strain, and the country is also facing severe pressures related to environmental capacity. Currently, China ranks first in the world in terms of SO2 emissions and second in terms of CO2 emissions; 90% of these emissions stem from the use of coal, which is a major factor contributing to the country’s long-term difficulties in addressing air pollution. Coal is an inefficient and highly polluting energy source. Under the new circumstances, whether China’s coal chemical industry can achieve sustainable development depends on its ability to meet both environmental protection requirements and economic efficiency goals. The development of coal chemical industry must be based on a sustainable development strategy; to this end, modern coal chemical industry needs to pursue a new path of development characterized by high levels of technological advancement, low resource consumption, minimal environmental pollution, and good economic returns. Modern coal chemical industry must be built on clean coal technology, earnestly adhere to the principle of giving priority to energy conservation and efficiency improvement, and vigorously adopt new coal conversion technologies that are energy-efficient, high-performance, and low-polluting. China has a low level of energy efficiency; its energy consumption per unit of GDP is 3.4 times the world average, making it one of the countries with the highest energy consumption in the world. The energy consumption associated with its key products is 40% higher than that in developed countries. China’s chemical industry has great potential for energy conservation, reduction of consumption, water conservation, and pollution control, yet the tasks ahead are substantial. To reduce pollution emissions and improve the utilization rate of coal, we must employ clean coal technologies in all stages, including its transportation, storage, processing, combustion, conversion, waste treatment, and pollution control. The development of coal chemical industry cannot come at the cost of damaging or even sacrificing the environment. Adopting environment-friendly policies and developing within the limits set by environmental capacity are prerequisites for the survival and sustainable development of this industry.    Our country has developed coal chemical industry under conditions of limited oil and gas resources but abundant coal. As long as clean coal technologies are utilized and energy conservation and efficiency improvement are given priority, and provided that the ecological environment permits it and there is economic viability, modern coal chemical industry can and should be developed actively. The more such coal chemical industries develop, the more they can reduce environmental pollution and dependence on petroleum resources.    Coal chemical industry uses coal as a raw material and, through chemical reactions, produces various chemicals; some of these chemicals can be used as energy sources (or referred to as energy-related chemical products). Modern coal chemical industry can contribute to conserving petroleum and natural gas resources and optimizing the energy structure. There is a consensus both domestically and internationally that, in the long term, using coal as a raw material to produce synthetic gasoline may be the main approach to addressing the shortage of liquid fuels. The development of modern coal chemical industry is based on practical considerations, takes local conditions into account, and makes rational and full use of China’s resources. The development of modern coal chemical industry holds strategic significance in China. From the perspective of the times, development requires a strategic vision. New coal chemical plants should be built with high standards, advanced technology, large scale, low pollution, good efficiency, and international competitiveness.
