Abstract
This paper analyzed the current situation and development trends of energy consumption and carbon emissions, and the current situation and development trend of coal consumption in China. In the context of recently established carbon peak and carbon neutralization targets, this paper put forward the main problems associated with the green and low-carbon development and utilization of coal. Five key technological innovation directions in mining were proposed, including green coal development, intelligent and efficient mining, low-carbon utilization and conversion of coal, energy conservation and emission reduction, carbon capture, utilization and storage (CCUS). Focusing on the above technological innovation directions, it is suggested to carry out three basic theories, including the theory of green efficient intelligent mining, clean and low-carbon utilization and transformation of coal, and CCUS. Meanwhile, it is proposed to develop 12 key technologies, including green coal mining and ecological environment protection, efficient coal mining and intelligent mine construction, key technologies and equipment for efficient coal processing, underground coal gasification and mining, ultra-high parameter and ultra-supercritical power generation technology, intelligent and flexible coal-fired power generation technology, new power cycle coal-fired power generation technology, the development of coal-based special fuels, coal-based bulk and specialty chemicals, energy conservation and consumption reduction, large-scale and low-cost carbon capture, CO2 utilization and storage. Finally, necessary measures from the governmental perspective were also proposed.
Highlights
The discovery and utilization of fossil energy has brought human beings from farming to industrial civilization
Global energy consumption was approximately 14.45 billion tons of oil equivalent, a yearon-year increase of 1.3%.Among them, fossil energy accounted for 84.3%, coal oil and gas consumption accounted for 27.0%, 33.1%, 24.2%, and non-fossil energy consumption accounted for 15.7% (BP Amoco 2020)
The carbon dioxide emissions caused by fossil energy combustion was absolutely dominant, accounting for about 85% (Intergovernmental Panel on Climate Change (IPCC) 2018a, b) (Figs. 2, 3)
Summary
The discovery and utilization of fossil energy has brought human beings from farming to industrial civilization. The 2020 Central Economic Work Conference emphasized the need to successfully achieve carbon peak and carbon neutrality targets, formulate an action plan for carbon emissions peaking by 2030, accelerate the adjustment and optimization of the industrial structure and energy structure, promote peak coal consumption as soon as possible while vigorously developing new energy sources, and improve the dual control system of energy consumption The proposal of this series of goals is of great strategic significance, which demonstrates China’s commitment to tackling climate change, and indicating the direction for its low-carbon energy transition
