About this reader

This Grade 6-8 science reading passage introduces students to Carbon Capture and Storage (CCS) technologies, an important method for reducing greenhouse gas emissions and combating climate change. Students will learn about the processes of capturing carbon dioxide (CO₂) from sources like power plants, transporting it, and storing it safely underground. The passage explains key scientific vocabulary terms and real-world examples, such as how CCS is used at factories and power stations. It aligns with NGSS standards and encourages critical thinking through a multiple-choice activity and writing tasks, which help deepen understanding of environmental science and technological solutions. The content is designed for readability, accessibility, and includes audio integration for diverse learners. This resource is ideal for classroom instruction or independent study.

CONTENT PREVIEW

Engineers are developing machines to remove carbon dioxide from the air to help fight climate change. These technologies offer new tools alongside natural solutions like planting trees. Carbon capture technology works in two main ways to reduce the amount of CO2 in Earth's atmosphere.

The first approach is called carbon capture and storage, or CCS. This method captures CO2 directly from smokestacks at factories or power plants before it escapes into the air. Special filters and chemical solutions trap the carbon dioxide as it rises from burning fossil fuels. Once captured, the CO2 is compressed into a liquid form. Workers then pump it deep underground into rock formations where it can stay trapped for thousands of years. Some companies also use captured carbon to make products like concrete or synthetic fuels.

The second approach is direct air capture, or DAC. These machines are more ambitious because they pull CO2 straight from the open atmosphere. Giant fans draw air through special filters that grab CO2 molecules. The process works similar to how a sponge soaks up water. Scientists then heat the filters to release the concentrated CO2 for storage or use. The Orca plant in Iceland, which started operating in 2021, can capture about 4,000 tons of CO2 each year. That equals the annual emissions from roughly 870 cars.

Evidence shows these technologies can work, but they face significant challenges. Both methods require large amounts of energy to run. CCS systems can use up to 30 percent of a power plant's energy output. Direct air capture machines need even more energy because atmospheric CO2 is much less concentrated than smokestack emissions. The costs remain high too. Capturing one ton of CO2 through direct air capture can cost between $600 and $1,000. Together, all carbon capture facilities worldwide currently remove less than 0.1 percent of global CO2 emissions each year.

Carbon capture technology matters because it may help reduce atmospheric CO2 levels in the future. Scientists explain that these tools could be especially useful for industries that are hard to clean up, like cement production. However, experts emphasize that carbon capture is not a substitute for reducing fossil fuel use. The technology works best as one part of a larger climate solution that includes renewable energy and energy efficiency.

Interesting Fact: If we tried to capture all of humanity's current CO2 emissions using today's direct air capture technology, we would need machines covering an area larger than the entire country of India.

What is the main purpose of carbon capture technology?

To create new fossil fuelsTo remove carbon dioxide from the airTo make concrete strongerTo power factories more efficiently

Where does carbon capture and storage (CCS) capture CO2?

From the open atmosphereFrom underground rock formationsFrom smokestacks at factories or power plantsFrom ocean water

What does the term 'emissions' mean in the context of this passage?

Underground storage areasGases released into the airSpecial filters for capturing CO2Renewable energy sources

How much CO2 does the Orca plant in Iceland capture each year?

About 870 tonsAbout 4,000 tonsAbout 10,000 tonsAbout 30,000 tons

Why does direct air capture require more energy than carbon capture and storage?

Because it uses bigger machinesBecause atmospheric CO2 is less concentrated than smokestack emissionsBecause it operates in colder climatesBecause it needs to heat the CO2 to very high temperatures

Based on the passage, what is one major limitation of current carbon capture technology?

It cannot store CO2 safelyIt only works in IcelandIt is expensive and captures only a small fraction of global emissionsIt releases more CO2 than it captures

According to scientists, carbon capture technology could be especially useful for which type of industry?

Solar panel manufacturingCement productionWind turbine constructionBicycle manufacturing

What can be inferred about the relationship between carbon capture technology and reducing fossil fuel use?

Carbon capture eliminates the need to reduce fossil fuel useCarbon capture should be used alongside reducing fossil fuel use, not as a replacementReducing fossil fuel use makes carbon capture unnecessaryCarbon capture and fossil fuel reduction cannot work together
