A total of 186 million kilowatt-hours of solar and wind power generated from Zhangjiakou, North China's Hebei Province, was sent to the Bohai oilfield on March 25. It was the first use of green power at a Chinese offshore oil and gas field.
The 186 million kWh accounts for 19 percent of the total purchased power in 2022 of the Bohai oilfield, realizing reduction of 164,000 tons of carbon dioxide.
Up to now, China National Offshore Oil Corporation (CNOOC) has purchased 286 million kWh of green power, equivalent to a reduction of 213,600 metric tons of carbon emission in the oil and gas industrial chain. It means that 1.09 million tons of crude oil produced at the oilfield will be carbon neutral crude oil that had zero carbon emissions during the production process.
Green power refers to the power generated via a process with zero or close to zero carbon emissions. Such electricity in China mainly includes that generated by solar and wind power.
Under the national support of double carbon policies, oil and gas enterprises are undergoing energy structure transformation in response to carbon reduction, in which green power is playing a key role.
In September 2021, China started green power pilot trading. CNOOC completed 286 million kWh of green power trading in its Guangzhou and Jibei power trading centers.
CNOOC plans to step up efforts to strengthen carbon reduction and to promote use of green power as one of the most direct and efficient energy-saving and carbon-reducing measures in the whole industry chain.
Meanwhile, the company will boost offshore wind power development to supply power to the oil and gas fields, and promote offshore wind power demonstration projects and integrated development of natural gas and new energy power generations, steps expected to meet CNOOC's demand for green power and contribute to the company's goal of building a low-carbon oil and gas industrial chain.
