How can mega-cities balance energy supply and carbon reduction?
2023/6/16
More than 170 billion kilowatt hours of electricity and 9 billion cubic meters of natural gas represent the energy appetite of Shanghai, a mega city, for one year. The "Shanghai Carbon Peak Implementation Plan" proposes that the proportion of non-fossil energy in the city's total energy consumption should reach 25% by 2030, so as to ensure the achievement of carbon peak by 2030. This means that while continuously supplying sufficient energy for the normal operation of the city, the fast-forward button for carbon reduction and greening must be pressed.
As the main force of Shanghai's energy supply, Shen Energy Group, a comprehensive energy enterprise group, provides 1/3 of Shanghai's electricity supply and more than 95% of its gas supply, Ni Bin, President of Shenneng Group, said that on the basis of building a firm line of defense for energy security and safeguarding the bottom line for people's livelihood, Shenneng has continuously expanded its green industry map, with the cumulative installed capacity of new energy increasing by 24% over the past year, the standard power supply coal consumption of system-held power plants being nearly 16g/kWh lower than the national average, and the "three vertical and three horizontal" development pattern of hydrogen energy continuing to deepen.
Whether from the installed capacity or power generation, coal power is still the top pillar to ensure the safe and stable supply of electricity in China at present and in the future. Based on China's energy endowment to coal-based basic national conditions, accelerate the clean and efficient use of coal, is to support the cornerstone of energy transformation.
This is inseparable from the coal power technology innovation, Shanghai International Carbon Expo, Shen can show the global coal power new benchmark - 2022 officially put into operation Shen can Anhui Pingshan power plant phase II project. The project has one of the world's largest single capacity (1350MW) coal power units, with a performance test rated coal consumption of 249.31g/kWh, breaking the world's highest level of low coal consumption and playing an important role in leading the green and low-carbon development of power.
The coal power industry has been known as "10 grams of coal consumption a generation of technology". Before that, the second Waigaoqiao Power Plant (hereinafter referred to as "Waigaoqiao Power Plant No. 2") and the third Waigaoqiao Power Plant (hereinafter referred to as "Waigaoqiao Power Plant No. 3") of Shenneng were also landmark projects leading the development level of coal power in China at different times. Waigaoqiao No.3 Power Plant has achieved the world's lowest annual average coal consumption of 276g/kWh and has been praised by the International Energy Agency as "the world's cleanest thermal power plant".
Based on the annual power generation capacity of 7 billion kilowatt hours, compared with the most advanced twice reheated million units built at the same time, the second phase of Shenneng Anhui Pingshan Power Plant can save about 105,000 tons of standard coal and reduce carbon dioxide emissions by about 260,000 tons per year.
"Coal power will still assume the important role of ensuring power security and promoting the development of renewable energy while enhancing the ability to keep power supply." Liu Wei, party secretary of Shenneng, a subsidiary of Shenneng Group, told reporters that the safe and stable supply of energy is always the top priority, "The first stand of energy transformation is to ensure the supply of electricity first, and then increase the proportion of green power on this basis."
There is still room for the clean transformation of the stock of coal power units. According to its introduction, at present, the second power plant and the third power plant outside of Shenneng, which belong to Shenneng, are undergoing desulfurization transformation, thus further improving the desulfurization capacity of the generating units and reducing the sulfide emissions required per unit of power generation. The second power plant in Wujing is undergoing renovation of high-temperature sub-critical units to improve coal utilization efficiency. After the renovation, coal consumption for power supply can be reduced by 25 g/kWh under 65% load conditions, which is expected to reduce carbon dioxide emissions by at least 180,000 tons per year.
Liu Wei said to the surging news, as of the end of last year, the new energy business of Shenneng shares across the country nearly 20 provinces, the next step will be to expand the direction of offshore wind power and Shago desert and other large-scale large base projects. With a planned installed capacity of 1.2 million kilowatts, Shenneng's Hainan CZ2 offshore wind power project is the first offshore wind power demonstration project in Hainan Province, "This project has already obtained the approval documents from the Development and Reform Commission of Hainan Province, and is undergoing construction procedures, and will substantially start construction in the near future."
Compared with the star clean coal power technology that has led its global counterparts for more than a decade, the hydrogen energy chess game built by Shen Energy in recent years is slightly low-key, but has taken shape.
Shanghai is building a highland of hydrogen energy industry. "Hydrogen energy is an important part of Shenneng Group's strategic emerging industries." Ye Chuhua, deputy director of hydrogen energy office of Shenneng Group and deputy secretary of the party committee and general manager of Shenneng Energy Creation under Shenneng Group, told reporters that the average daily hydrogen refueling capacity of the oil-hydrogen joint station on Pingxiao Road, which is laid out in the new area of Lingang in cooperation with PetroChina, has exceeded 80% of the designed capacity. "The design hydrogen refueling capacity of one station is 1 ton per day, and the average daily refueling volume has exceeded 800 kg recently. There are often vehicles lining up at the entrance of the hydrogen refueling station waiting for hydrogen refilling."
The infrastructure is only part of the layout of the whole industry chain. According to Ye Chuhua, the development of hydrogen energy business of Shenneng is in the pattern of "three vertical and three horizontal": "three vertical" focuses on the high-end manufacturing field, laying out three major products of hydrogen preparation, storage and transportation equipment and fuel cell, forming the high-end manufacturing industry cluster of hydrogen energy upstream, midstream and downstream, with Zhejiang Blue Energy, Hydrogen Morning Technology and Shanghai Kunhua, Zhejiang Blue Energy, Hydrogen Morning Technology, Shanghai Kunhua, RuiBike and other head companies in different parts of the hydrogen industry chain are the companies that Shen can lay out; "three horizontal" around the application scene to build, to build the Shanghai hydrogen energy base, the provincial and foreign hydrogen energy industry chain application integration base, hydrogen energy multiple application scene, etc., to realize the complete commercial closed loop of hydrogen energy applications.
According to Ye Chuhua, Shanghai will also form a multi-way hydrogen source to guarantee the development of Shanghai's hydrogen energy industry in the future. In addition to chemical by-product hydrogen, it is expected to realize electrolytic water hydrogen production from offshore wind power, long-distance hydrogen transmission from renewable energy resource-rich areas and biological hydrogen production in the Yangtze River Delta. "In three to five years, the main application areas of hydrogen energy will still be mainly transportation. In another five to ten years, hydrogen energy will also be applied on a large scale in the difficult emission reduction areas of industry. In another long term, hydrogen energy will enter the residential life scenario."
