世界二氧化碳埋存及利用方式研究

Study on worldwide carbon dioxide storage and utilization methods

预计全球石油消费2025-2030年将比现在增长50%左右,这对保持大气中温室气体浓度的长期稳定、缓解气候变暖是严峻的挑战。埋存CO_2是避免气候变化的有效途径之一,埋存对环境产生的影响较小、成本较低、符合相关国际法规。CO_2地下埋存的主要场所有枯竭的油气藏、深部的盐水储层、不能开采的煤层、深海等。CO_2地下埋存将有效应对能源需求增长带来的CO_2排放增加的挑战,为将全球气温上升控制在比工业革命前水平高2℃以内提供理论和实践依据。

It is estimated that,between 2025 and 2030,global petroleum consumption will increase by around 50% in comparison with present rates.This will pose a considerable challenge to the maintenance of stable atmospheric greenhouse gas concentrations long-term and to the slowing of global warming.Carbon dioxide storage,characterized by low environmental impact, relatively low costs,and compliance with international regulations,is one effective approach to climate change prevention.Major sites for carbon dioxide storage include depleted oil and gas mines,deep salt water bearing reservoirs,unmineable coal beds,deep sea,etc. Underground carbon dioxide storage effectively addresses the challenge posed by the increasing CO2 emissions that have come with growing energy demand,and provides a theoretical and practical basis for keeping the global temperature increase within 2℃of pre-Industrial Revolution levels.
