Abstract: The world today has entered a new era of superimposed development of the sixth scientific revolution, the fourth industrial revolution, and the third energy revolution. To address the new challenges of global climate change and the energy green and secure transformation, humanity will surely seize the new opportunities to break through the limitations of traditional single-energy replacement pattern and the barriers among energy systems, and accelerate the construction of a new paradigm of synergistic and intelligent multi-energy integration, characterized by a six-in-one model of coal, oil, natural gas, new energy, carbon neutrality and artificial intelligence. Energy science, grounded in the evolutionary processes of the Earth system, investigates the formation and distribution of various energy resources, regional evaluation, development and utilization, orderly substitution, and future prospects across temporal and spatial scales. From the perspective of building China as an energy powerhouse, and based on research on global green energy transition, climate change, carbon neutrality, China’s energy resource endowment and energy green and secure transition, this paper proposes the concept, theoretical framework, technical pathways, and development strategies of the Integrated Whole-Energy System (IWES). IWES refers to a safe, efficient, and intelligent mega-system in which aboveground and underground energy resources exhibit genetic continuity, ordered substitution, overlapping coexistence, and coordinated integration for utilization. The development philosophy of IWES advocates the establishment of a holistic energy system perspective and the construction of six subsystems, namely the Whole Petroleum System, the Whole Coal-rock System, the New Energy System, the Multi-Energy System, the Super Energy System, and the Carbon Cycle System. The strategic approach of IWES emphasizes clean coal with carbon emission reduction, stabilized oil with increased gas production, strengthened renewables with enhanced reserves, multi-energy integration, intelligent economy, and green and safe development. The technological priorities of IWES focus on nine critical areas, including coal cleaning, in-situ conversion of shale and coal resources, wind energy, solar energy, hydrogen energy, energy storage, geothermal energy, controllable nuclear fusion, and intelligent governance. The development pathway of IWES follows a three-step roadmap, namely to consolidate multi-energy complementarity during foundation and integration period, to break through core technologies during accelerated transformation period, and to establish an intelligent energy ecosystem during system maturity period. The significance of IWES lies in the potential to address the inherent contradictions of the fossil energy "impossible triangle", drive the building of a new energy system with new energy at its core,facilitate the achievement of carbon neutrality, empower the construction of an energy powerhouse, and contribute a "China Solution" to the global energy green transition and sustainable development of the Earth.

Key words: Integrated Whole-Energy System, energy powerhouse, energy security, energy green transition, energy secure transition, carbon neutrality, multiple energy integration, energy triangle, energy equivalent

摘要： 当今世界进入第6次科技革命、第4次工业革命和第3次能源革命"三大革命"叠加发展的新时代。为应对全球气候变化与能源绿色安全转型的新挑战,人类必将抓住突破传统单能源接替发展局限与能源系统间壁垒的新机遇,加快构建煤炭+石油+天然气+新能源+碳中和+人工智能的"煤-油-气-新-碳-智"六位一体的多能协同智慧融合发展新模式。能源科学是立足地球系统演化,从时间和空间尺度研究各类能源的形成分布、评价选区、开发利用、有序替代、发展前景等内容的科学。从中国建设"能源强国"的角度出发,基于全球能源绿色转型、气候变化、碳中和目标、中国能源资源禀赋特征与能源绿色安全转型的研究,提出了"全能源系统"的概念、理论框架、技术路径与发展举措。全能源系统是指地上地下能源形成亲缘有序、叠合共生、协同融合、利用接替的高效安全智慧的大能源系统。倡导树立大能源系统观,其发展思想是构建全油气系统、全煤岩系统、新能源系统、多能源系统、超级能源系统、碳循环系统的"六个子系统";其发展思路是洁煤降碳、稳油增气、强新增储、多能互融、智能经济、绿色安全;其发展技术是聚焦煤炭清洁化、页岩煤岩地下原位转化、风能、光能、氢能、储能、地热、可控核聚变和智慧管控九大关键方向;其发展路径是按照在筑基融合期夯实多能互补基础、在转型加速期突破核心技术、在体系成熟期建成智慧能源生态的"三步走"规划;其发展意义是或将破解化石能源"不可能三角"固有矛盾,驱动构建以新能源为核心的新型能源体系,助力实现碳中和目标,赋能能源强国建设,在全球能源绿色转型、绿色地球建设中贡献"中国方案"。
