Question

carbon capture and storage (ccs)
carbon sequestration
imagine your plants and factories releasing tons of carbon dioxide into the air, contributing to climate change. carbon capture and storage (ccs) is like a superhero technology trying to grab that co₂ before it escapes. special equipment can capture the carbon dioxide right at the source, preventing it from entering the atmosphere. think of it like a giant vacuum cleaner for industrial emissions. once captured, the co₂ is compressed and then transported, often through pipelines, to a safe and permanent storage location.
the long-term storage of that captured carbon dioxide is called sequestration. one promising method of sequestration currently in use in norway involves injecting the compressed co₂ deep underground into porous rock formations that are capped by impermeable layers. these formations act like a natural seal, preventing the carbon dioxide from leaking back into the atmosphere.
carbon capture and storage (ccs) is a crucial part of the climate equation. while still a developing technology, it holds the potential to be a vital tool to reduce greenhouse gas emissions from major industrial sources.
what is done with excess carbon dioxide after it is captured?
while it is being captured, it is burned at a high temperature and separated into carbon and oxygen.
once captured, the co₂ is compressed and then transported to a safe and permanent storage location.
after it is captured, it is turned into a liquid then released back into the atmosphere.
after it has been captured, the carbon dioxide is mixed with other chemicals then put in dumpsters.

Explanation:

The text clearly states that once captured, the CO₂ is compressed and then transported to a safe and permanent storage location. This directly matches the second option. The first option about burning and separating into carbon and oxygen is not mentioned. The third option of releasing back into the atmosphere is contrary to the purpose of CCS. The fourth option of mixing with chemicals and putting in dumpsters is also not described in the text.

Answer:

Once captured, the CO₂ is compressed and then transported to a safe and permanent storage location.
