摘要
深地储能是指将石油、天然气、氢气、氦气、压缩空气以及二氧化碳等能源或能源物质储存在深部地下空间(地质体).这对于优化我国能源结构布局、提升能源储备能力有显著的推动作用,并且能从根本上保障国家能源安全及战略物资的稳定供应,构成了我国能源储备战略的关键发展方向.本研究梳理了全球在石油、天然气、压缩空气、氦气和氢气储能技术的技术战略规划布局情况.利用文献计量方法深度挖掘分析了国内外在该领域的发展态势与前沿主题.结果显示,中国在该技术领域发表论文近两千篇,位居全球首位;中国的高水平研究成果位居全球第二,是本领域最重要的研发国家之一.深地储能的研究热点主要集中在高分辨率精细模拟、储能介质多尺度运移、储能地质体性能演化、智能建造及模拟和智慧运行等方面.
Abstract
Deep underground energy storage refers to the storage of energy or energy substances such as oil,natural gas,hydrogen,helium,compressed air,and carbon dioxide in deep underground space(geological bodies).It can fundamentally guarantee national energy security and stable supply of strategic materials.This move not only conforms to the needs of the times but also constitutes a key development direction of China's energy reserve strategy.This study reviews the global technical strategic planning layout of energy storage technologies for oil,natural gas,compressed air,helium,and hydrogen.Using bibliometric methods,we deeply analyzes the development trends and frontier topics in this field at home and abroad.The results show that China has published nearly two thousand papers in this technical field,ranking first in the world;China's high-level research achievements rank second in the world,making it one of the most important research and development countries in this field.The research hotspots of deep underground energy storage mainly focus on high-resolution fine simulation,multi-scale migration of energy storage media,performance evolution of energy storage geological bodies,intelligent construction and simulation,and intelligent operation.
