Innovations of carbon-neutral petroleum pipeline: A review

As one of the major energy-intensive industries, petroleum pipelines are facing with huge pressure from carbon-neutral policies. Conforming to green development, the traditional pipeline industry should advance intelligent transition and take the reduction of carbon emissions as a strategic priority. Focusing on effective and low-carbon operation of petroleum pipelines, this review elaborates the challenges and solutions covering four aspects, including the system reform, intelligent monitoring and control, intelligent operation management and integrating with the clean energy transmission network. The related literature and industrial practices have been systematically reviewed to conclude with general guidelines and examples for competitiveness enhancement, energy saving and emission reduction. Future directions are also proposed on the basis of the research gaps.
