on january 12th, the civil engineering foundation of the carbon capture, utilization, and storage (ccus) demonstration project's first-phase carbon dioxide (co2) tank at the ningdong base of the china energy's 3 million tons/year carbon capture, utilization, and storage (ccus) full-industry demonstration project (hereinafter referred to as the "ccus demonstrative project") was completed. this marks the completion of the civil engineering foundation for the largest ccus demonstration project currently under construction in china.

the ccus demonstration project consists of two parts: the "ningdong base carbon source capture project," managed by china energy’s ningxia coal industry, and the "changqing oilfield (ningxia) enhanced oil recovery (eor) and sequestration project," managed by petrochina's changqing oilfield branch. the project captures the co2 emissions from the largest single-unit modern coal-to-liquid project with a capacity of 4 million tons/year, and then conducts enhanced oil recovery (eor) and sequestration at the largest domestic oil and gas production base, the changqing oilfield, achieving green carbon reduction cooperation between modern coal chemical industry and large-scale oil and gas field development.

the project commenced comprehensive construction at the ningdong base on may 19, 2023, with a three-phase construction plan. the first phase, starting construction on may 19, 2023, is expected to be completed and put into operation in 2024. the main components include a 500,000 tons/year co2 capture and liquefaction unit, a 400,000 tons/year co2-eor (co2-enhanced oil recovery) unit, and a 100,000 tons/year co2 utilization project in underground coal mines. the second phase, planned to commence in 2024, aims to be completed and operational by the end of december 2025, focusing on co2 capture and compression, with an oil recovery and sequestration scale reaching 1 million tons/year. the third phase, anticipated to begin during the "14th five-year plan" period, aims to be completed with a capacity of 1.5 million tons/year for co2 capture and compression, along with oil recovery and sequestration, and a 500,000 tons/year ccs (carbon capture and storage) project. the total carbon dioxide reduction scale is expected to reach 3 million tons/year by the end of the "15th five-year plan."

after completion and operation, the project is expected to annually reduce co2 emissions by 3 million tons, equivalent to planting nearly 27 million trees or keeping approximately 180,000 economy cars off the road for one year. the project will serve as a demonstration for large state-owned enterprises to engage in cross-industry green carbon reduction cooperation and contribute to the beneficial exploration of low-carbon development in the modern coal chemical industry.
