问题 What is the function of carbon capture technology?
A coal-fired power plant in Texas is on its way to capturing 1. 4 million tons of carbon dioxide that previously would have been released into the air.
   Rather than building an entirely new facility, the Petra Novo project will apply carbon capture technology to an existing coal-fired power plant — helping to advance the technologies that help enable cleaner energy production from fossil energy resources and reduce greenhouse gas emissions.
   The Houston-area project was awarded $ 167 million from the U. S. Department of Energy to capture emissions from 60 megawatts of generation.
   Project sponsor NRG Energy Inc. and JX Nippon decided they could quadrupled the size of the project — expanding the design to capture the emissions from 240 megawatts of generation — with no additional federal funding.
   When completed, the project has the potential to capture the same amount of CO2 each year as taking 250, 000 cars off the road.
   Using a process previously tested in a three-year pilot scale test in Alabama, the project will capture up to 90 percent of CO2 from the power plant. The captured carbon dioxide will then be compressed, dried and transported to an oil field where it will be used to recover previously unreachable oil — a process known as Enhanced Oil Recovery or EOR.

选项 A、Replacing coal-fired power plant.
B、Reusing fossil energy resources.
C、Capturing carbon dioxide from the air.
D、Making existing energy production cleaner.

答案D

解析 原文指出捕碳技术将化石能源产生的二氧化碳捕获,使其更加清洁。在本文中,捕碳技术不是从空气中捕捉二氧化碳,所以选项C不正确,选项D符合原文。carbon capture technology意为“捕碳技术”。这种技术能够将电厂或工厂烟囱中的二氧化碳及时捕捉,以免排放到空气中,污染环境。捕捉到的二氧化碳会被压缩、深埋。
