Pioneer of the "Carbon" Road Chasing the Wind and Light

In 2023, Sinopec focused on the "dual carbon" goal, accelerated the integration of wind and solar business and main business development, and promoted green and low-carbon production processes. With a unique posture of "chasing the wind and walking in the light", it painted a beautiful picture of "infinite beauty, strong green atmosphere of Sinopec".

Exquisite layout, turning idle land resources into a source of efficiency

In 2023, while consolidating its main oil and gas business, Sinopec seized the opportunity to cultivate the new energy industry, clearly positioning new energy as an important strategic emerging industry, deepening the structural reform of the energy supply side, vigorously developing new energy such as wind and solar power, and focusing on building an energy supply and consumption system that integrates traditional energy and new energy sources.

Well stations, well sites, factory areas, oil depots, gas stations, and idle inefficient land have become favorable conditions for enterprises to pursue excellence. Each enterprise strengthens its investigation and transformation of idle land from a cost burden in the past to a source of efficiency, fully promoting the construction of wind and solar power projects, and conducting centralized and large-scale development in areas with local conditions.

In terms of "station+photovoltaic", Shengli Oilfield has revitalized 700 acres of idle land in the ash field of the power plant to build a 37 MW photovoltaic power station; Jianghan Oilfield has collaborated with professional companies to activate over 1800 acres of idle land to build 46 photovoltaic power stations, with an installed capacity exceeding 100 megawatts and an annual photovoltaic power generation exceeding 90 million kilowatt hours.

In terms of "well site+wind power+photovoltaic", Jiangsu Oilfield utilizes the vacant land of well sites and stations to build 159 distributed photovoltaic power stations, activate more than 500 acres of land resources, and have a new energy generation capacity of 130 million kilowatt hours per year. The proportion of self use green electricity is nearly 1/4.

In terms of "gas stations+photovoltaics", sales enterprises fully utilize the open space of gas stations to build photovoltaic power generation projects and actively create carbon neutral gas stations. Among them, the photovoltaic coverage rate of Hainan Petroleum Energy Station reached 66.1%; The Jiangsu Nanjing Petroleum Zhonghe Road Energy Station has built the first waste free energy station in Nanjing by constructing photovoltaic charging facilities and other facilities.

Each enterprise also starts from "leftover" sites such as factory areas, roofs, water surfaces, ponds, etc., and plans uniformly, concentrates and implements them step by step, creating a "photovoltaic+environmental governance" power generation model. In terms of "factory+roof+photovoltaic", companies such as Shanghai Petrochemical, Jiujiang Petrochemical, Maoming Petrochemical, and Yizheng Chemical Fiber fully utilize resources such as factory areas, factories, and parking lots to build photovoltaic power generation projects. On August 31, 2023, the 24.5 MW distributed photovoltaic power generation project in Maoming Petrochemical Port Zone 1 was fully connected to the grid for power generation. This project utilizes 273.5 acres of idle land in the factory area, generating over 29 million kilowatt hours of green electricity annually.

In terms of "water surface+photovoltaic", Shanghai Petrochemical utilizes the water surface of the Nansuitang River to build a photovoltaic power station with an installed capacity of 5.84 MW, forming a green development industrial demonstration belt for viewing. Jiangsu Oilfield fully utilizes the water surface, field ridges, and idle land resources of Yong'an Farm's fish ponds to build a 3.7 MW photovoltaic power station, forming a "complementary fishing and lighting" model.

New Star Company fully leverages the advantages of new energy professional technology, focusing on the goal of "replacing existing capacity with green electricity and building new capacity with green electricity supporting facilities", strengthens cooperation with various enterprises, fully utilizes their own land, roof, water surface and other resources, and explores wind and photovoltaic development and utilization projects in different scenarios.

Featured applications to promote deep integration of oil and gas production with new energy

In 2023, Sinopec's oil and gas enterprises will seize the opportunity of green transformation, actively promote the deep integration of oil and gas exploration and development with new energy, coordinate the deployment of new energy, shale oil development, CCUS, gas storage construction and other projects, and comprehensively use source network load storage and multi energy complementary technologies to promote the construction of integrated innovation demonstration zones, and actively create "new energy+" comprehensive application characteristic scenarios.

In the exploration and development of shale oil in the Niuye area of Shengli Oilfield, production energy is achieved through "photovoltaic+grid power". The photovoltaic station of Shengli Power Plant generates green electricity directly for shale oil drilling rigs, with green electricity accounting for over 50%.

Jiangsu Oilfield has collaborated in the wind and photovoltaic businesses in the Jiangdu Oil Region, and is supporting the Caozhuang energy storage system to establish a high proportion green energy substitution demonstration zone with "green power as the main source, multiple energy complements, and source load balance". The proportion of green energy in the region exceeds 50%.

The CCUS peak shaving center of East China Petroleum Bureau will construct a photovoltaic power station to provide green lighting electricity for the peak shaving center; Jiangsu Oilfield Union 38CCUS Demonstration Zone is constructing a photovoltaic project at the well site, becoming one of the first carbon neutrality demonstration sites of Sinopec; The 13.39 MW distributed photovoltaic power generation project of Jianghan Oilfield Salt Chemical Plant has been successfully connected to the grid, promoting the "new energy+salt brine chemical" all green production mode and further enhancing industrial competitiveness.

"Wind power+" and "photovoltaic+" have become beautiful landscapes for the green development of various enterprises.

Fine operation and maintenance, successfully paving a new path for improving quality and efficiency

In order to improve the efficiency of new energy development, various enterprises have fully utilized information technology and intelligent technology, effectively solving development challenges such as new energy consumption and peak shaving. Through the dual wheel drive model of "industrial scale development" and "project refined operation and maintenance", they have successfully carved out a new path to improve quality and efficiency.

In terms of the full chain operation of green power, Shengli Oilfield has taken the lead in creating the first large-scale "source network load storage" integrated smart energy system with independent intellectual property rights in the domestic oil and gas field. Through the interactive operation of "source network load storage", it drives the optimization of the entire energy system resources, and the power and grid sides can flexibly allocate according to the needs of users.

In terms of power facility management, the Zhejiang Petrochemical 220 kV substation within the Zhenhai Refining and Chemical Plant is the first unmanned high-voltage substation of Sinopec to benchmark the power system. By laying photovoltaic systems in suitable areas of the substation, zero carbon operation has been achieved.

In terms of green power operation and maintenance, the ash field photovoltaic project of Shengli Oilfield Power Plant adopts 198 self generating intelligent cleaning robots for maintenance, which not only meets the cleaning needs of large-scale photovoltaic panels, but also can adjust the cleaning process and progress according to user needs, ensuring that photovoltaic panels can be cleaned in a timely manner and improving power generation efficiency.

Faced with the mandatory question of "integrated development", various enterprises of Sinopec gave a brilliant answer sheet on the "carbon road pioneer, chasing the wind and light".
