In early winter, the western end of the Hexi Corridor gradually fades away from the colorful autumn scenery and puts on a cold and stern "coat". Walking into the Laojunmiao Oil Extraction Plant in Yumen Oilfield, looking around, one can see colorful scenery. Amidst the mountains, orange oil extraction machines tirelessly "kowtow" to extract oil. Not far away, thousands of photovoltaic panels form a blue 'ocean', constantly converting sunlight into electricity. The colorful scenery around Laojunmiao Oil Extraction Plant is a microcosm of the transformation and revitalization of traditional industries in Gansu Province. As the first pilot demonstration project for comprehensive utilization of solar energy in Yumen Oilfield, the annual power generation here reaches 1.55 million kilowatt hours, which is equivalent to reducing carbon emissions by 1545 tons. Yumen Oilfield was developed in 1939 and is known as the "cradle of China's petroleum industry". After 85 years of development, Yumen Oilfield inevitably faces problems such as insufficient replacement of oil and gas resources, declining resource grades, and increased difficulty in stabilizing production. Therefore, transformation and upgrading are imperative. Jiuquan City, Gansu Province, where Yumen Oilfield is located, is rich in wind and solar resources and has built a wind power base with a capacity of tens of millions of kilowatts. With the proposal of the "dual carbon" target, Yumen Oilfield is based on its resource advantages, moving towards "new" and "green" development. In 2020, Yumen Oilfield formulated its first new energy business development plan. In September of that year, the construction of the 887 kW solar energy comprehensive utilization demonstration project at Laojunmiao in Yumen Oilfield began, and it was completed and put into operation in just two months. Since then, Yumen Oilfield has rapidly advanced on the path of new energy. In 2021, the 200 MW photovoltaic power generation demonstration project was successfully connected to the grid, becoming the first large-scale centralized grid connected power generation demonstration project in the PetroChina system; In 2023, a 300 MW photovoltaic power station will be connected to the grid for power generation, with an average annual power generation of over 600 million kilowatt hours after completion, which can meet the annual electricity demand of 200000 households. In addition to actively laying out green power, Yumen Oilfield is also opening up a new track for renewable energy hydrogen production. In March of this year, the first large-scale renewable energy hydrogen production project in Yumen Oilfield was successfully put into operation, with an annual production capacity of 2100 tons of green hydrogen with a purity of 99.99%. It has become the main raw material for Yumen Oilfield Refinery and surrounding chemical enterprises, and has initially formed a hydrogen supply chain in provinces and regions such as Gansu, Ningxia, and Xinjiang, achieving a seamless connection from production to utilization. Data shows that as of now, Yumen Oilfield has built 6 photovoltaic power generation projects with a total installed capacity of over 540000 kilowatts and an annual power generation of over 1 billion kilowatt hours. It is expected that by 2025, the cumulative installed capacity of new energy will reach 2 million kilowatts, and the production scale of green hydrogen will reach 10000 tons. The pattern of comprehensive energy development of "oil, gas, electricity, and hydrogen" will accelerate. From black crude oil to green electricity and hydrogen, this "elderly" old oil field has embarked on a second entrepreneurial journey and achieved a magnificent transformation. Industry is the "ballast stone" of the economy and the "stabilizer" of development. Gansu, as an important old industrial base in China, has accumulated rich experience in traditional fields such as petrochemicals, non-ferrous metallurgy, and equipment manufacturing over the years, making tremendous contributions to the country. At present, Gansu is based on its industrial foundation, accelerating structural adjustment and promoting transformation, and promoting the development of traditional industries towards high-end, intelligent, and green development. The "Republic's eldest son" Lanzhou Petrochemical Company, located on the banks of the Yellow River in Lanzhou, has an annual crude oil processing capacity of over 10 million tons and is the largest refining and chemical enterprise in western China. Faced with the profound adjustment of the global energy landscape in the new era, Lanzhou Petrochemical has actively proposed new goals of "reducing oil and increasing chemical production, reducing oil and increasing characteristics, reducing carbon and increasing green", and plans to invest more than 24 billion yuan to implement a million ton ethylene transformation project, which is equivalent to rebuilding Lanzhou Petrochemical. Lanzhou Lanshi Group Co., Ltd., a veteran equipment manufacturing enterprise, adheres to the high-end transformation of traditional refining and chemical equipment, oil and gas drilling and production equipment and other advantageous industries, while creating strategic emerging industries mainly focused on "nuclear hydrogen photovoltaic storage" new energy equipment and high-end alloys and nano new materials. In Huating, Pingliang, the "coal capital of Longdong", Huating Coal Industry Group Co., Ltd., a key coal enterprise in Gansu Province, is constructing a 600000 ton annual coal to methanol project, which is the first large-scale coal chemical project in Gansu Province and is turning "Wujin" into "Platinum". The beneficial explorations of renovating the old and nurturing the new one by one have revitalized the vitality of Gansu's old industrial base and made its growth momentum stronger. In the first three quarters of this year, the growth rates of the added value of the secondary industry and the added value of industries above designated size in Gansu Province reached 9% and 12% respectively, ranking second in the country. The role of the industrial economy as the backbone continues to be highlighted. (New Society)
