一、今日导读

　　冰川融化、海平面上升、极端天气频发……对于这些新闻里的高频词,大家恐怕已是"耳熟能详”。随着全球变暖问题变得日益严峻,怎样处理大气中不断增加的二氧化碳是一个世界性难题。对此,除了践行低碳生活、用绿色能源替换石油和煤炭这些"传统途径",科学家们还提出了一种新思路一一把空气中的二氧化碳直接"捉"回来。这是一种怎样的"黑科技”?它对于缓解全球变暖又有着怎样的特殊意义?让我们跟着 Eein 老师一起来看。

带着问题听讲解

• 如何理解 capture 这个词?短语 dispose of 是什么意思?
• 根据文章,有哪些处理二氧化碳的方法?

二、原文讲解

The world's biggest plant to capture CO2 just opened in Iceland

世界最大的二氧化碳捕集工厂不久前在冰岛启用

A major new facility to pull carbon dioxde out of the atmosphere started operating in Iceland on Wednesday , a boost to an emerging technology that experts say could eventually play an important role in reducing the greenhouse gases .

本周三(9月8日),一套新的大型设施开始在冰岛运营,该设施用于从大气中吸收二氧化碳。这推动了一项新兴技术的发展;专家称,这项技术最终可能会在减少温室气体方面扮演重要角色。

The plant , perched on a barren lava plateau in southwest Iceland , is the biggest of its kind , its builder says . Human - sized fans are built into a series of boxes . They sip carbon dioxide out of the air , catching it in spongelike flters . The filters are blasted with heat , freeing the gas . Then it is mixed with water and pumped deep into underground basalt caverns , where over time it turns into dark - gray stone .

这座工厂坐落于冰岛西南部的一片荒芜的熔岩高原之上。其建造者称,它目前是同类型工厂中最大的一个。和人一般大小的风扇被安装在一系列的箱子里。它们把二氧化碳从空气中吸出来,并把它们"捕捉"到一个类似海绵的过滤器中。(接着,)这些过滤器会被热流喷射,从而将(二氧化碳)气体释放出来。之后,这些气体将与水混合,并被泵入地下的玄武岩洞穴深处。在那里,这些二氧化碳会渐渐变为深灰色的石头。

 Pumping CO2 into the ground is just one way to dispose of it . It can also go to other uses . Energy companies can mix the carbon dioxide with hydrogen to make fuel . Farmers can feed their plants with it .

将二氧化碳泵入地下只是对它们的处理办法之一。它们也可以用于其他方面。能源公司可以将二氧化碳与氢气混合来制造燃料。农民则可以用它们"饲养”作物。

 By 2050, humanity wil need to pul nearly a billion metric tons of carbon dioxide from the atmosphere every year through direct air capture technology to achieve carbon neutral goals , according to International Energy Agency recommendations .

根据国际能源署的建议,到2050年,人类将需要通过"直接空气捕获"技术,每年从大气中吸收将近十亿公吨的二氧化碳,方可实现"碳中和"目标。

 The plant in Iceland will be able to capture 4,000 metric tons annually - just a tiny fraction of what will be necessary , but one that Climeworks , the company that built it , says can grow rapidly as efficiency improves and costs decrease .

冰岛的这家工厂每年将能捕获4000公吨(二氧化碳)——(这个数字)仅仅是所需数量的极小一部分,但工厂的建造公司 Climeworks 表示,随着效率的提升和成本的下降,这一数字将会迅速增长。

 "This is a market that does not yet exist , but a market that urgently needs to be built ,"said Christoph Gebald , a Swiss engineer who co - founded and co - directs Climeworks . "This plant that we have here is really the blueprint to further scale up and really industrialize ."

瑞士工程师克里斯托弗.格巴尔德是 Climeworks 公司的共同创始人及董事之一,他说:“这是一个尚不存在,但急需建设的市场。我们在这里的这家工厂,真可以说是未来进一步扩大规模和真正实现产业化的范本。”
