In face of global warming,much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.But while much of the research and innovation has concentrated on finding less-polluting energy alternatives,it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs.
In the meantime,the amount of CO2 in the air is rapidly approaching the limits proposed by the Intergovernmental Panel on Climate Change (IPCC).“As long as we’re consuming fossil fuels,we’re putting out CO2,”says Klaus Lackner,a geophysicist at Columbia,University” We cannot let the CO2 in the atmosphere rise indefinitely.”
That sense of urgency has increased interest in capturing and storing CO2,which the IPCC says could provide the more than 50% reduction in emissions thought needed to reduce global warming.“We see the potential for capture and storage to play an integral role in reducing emissions,” says Kim Corley,Shell’s senior advisor of CO2 and environmental affairs.That forward thinking strategy is gaining support.The U.S.Department of Energy recently proposed putting $1 billion into a new $2.4 billion coal-burning energy plant.The plant’s carbon-capture technologies would serve as a pilot project for other new coal-burning plants.
But what do you do with the gas once you’ve captured it?One option is to put it to new uses.Dakota Gasification of North Dakota captures CO2 at a plant that converts coal into synthetic natural gas.It then ships the gas 200 miles by pipeline to Canada,where it is pumped underground in oil recovery operations.In the Netherlands,Shell delivers CO2 to farmers who pipe it into their greenhouses,increasing their yield of fruits and vegetables.
However,scientists say that the scale of CO2 emissions will require vast amounts of long-term storage.Some propose storing the CO2 in coal mines or liquid storage in the ocean,Shell favors storing CO2 in deep geological structures such as saline(盐的) formations and exhausted oil and gas fields that exist throughout the world.

面对全球变暖,很多努力都集中在通过各种策略减少温室气体排放.不过,虽然很多研究和创新都集中在寻找较环保的替代能源,这可能是几十年的清洁能源技术,如风力和太阳能满足我们的能源需求显著部分之前.
在此期间,二氧化碳在空气中的含量正在迅速接近所提出的政府间气候变化委员会（IPCC）的限制.“只要我们消耗化石燃料,我们就会把这些二氧化碳,”克劳斯·莱克纳,地球物理学家在哥伦比亚大学说,“我们不能让大气中的二氧化碳上涨下去.”
危机感增加的兴趣在捕捉和存储的二氧化碳,其中IPCC说可以提供以为需要在排放减少50％以上,以减少全球变暖.“我们看到捕获和储存的电位,以减少起到了不可或缺的作用排放量,“金科利,CO2和环境事务的壳牌的高级顾问说.这一前瞻性的思维策略,获得支持.美国能源署最近提出放六1十亿到一个新的价值2.4十亿燃煤发电厂.该工厂的碳捕获技术将作为一个试点项目,其他新的燃煤电厂.
但你是做什么用的气体,一旦你捕获了吗?一种选择是把它的新用途.北达科他州达科他气化二氧化碳捕获在一个工厂,将煤转化为合成天然气.它通过管道输送到加拿大,它是在油回收操作井下泵送然后船的气200英里.在荷兰,壳牌提供二氧化碳农民谁管就到他们的大棚,增加水果和蔬菜的产量.
然而,科学家们说,二氧化碳排放量的规模,需要大量的长期存储.有人建议在存储煤矿或液体储存二氧化碳在海洋中,壳牌主张封存二氧化碳在全世界存在的深部地质构造,如盐水（盐的）地层和疲惫的石油和天然气田.
