Strategic thinking on pipeline network development for flexible multi-media transport and intelligent efficient utilization under dual carbon vision
Abstract
Under the dual carbon strategy, the pipeline, typically as a critical infrastructure for the energy industry and modern transportation system, must accelerate its adaption to the new development requirements of “low-carbon energy production, reshaped energy transmission pattern and flexible energy consumption”, so as to well balance its synergism among safety, efficiency, green intelligence and value enhancement. Herein, years of fruitful technical achievements in oil & gas storage and transportation were reviewed based on the identification of development needs of the country and industry. The advantages of pipeline network reform and storage & transportation technology accumulation also contributed to the analysis of strategic needs and construction goals of developing flexible multi-media transportation and intelligent efficient utilization. An exploratory thinking was triggered regarding the accelerating integration and innovation of “oil and gas + new energy” and “storage and transportation + digital intelligence”, as well as the focus evolved and extended from “steel pipeline + fluid mechanics” to “intelligent pipeline network + system engineering” in terms of storage & transportation technology. A deep analysis was made for the new development requirements for key technologies, such as superelastic modified transportation of crude oil pipeline, drag reduction and transportation increase of natural gas pipeline, pipeline transportation of pure hydrogen/hydrogen mixture,pipeline transportation of supercritical/dense-phase carbon dioxide, intellectualization of pipeline network and energy interconnection, et al. A comprehensive and constructive consideration was given to the intelligent construction of the national energy pipeline, with a view to providing demand reference and technical support for the development of pipeline network under the new energy system.
