Storing CO2 underground could help the fight against climate change

Despite the emergence of renewable energy sources such as large-scale wind and solar power, our planet is still heavily reliant on fossil fuels.

In the U.S., for example, the Energy Information Administration states that petroleum, natural gas and coal accounted for roughly 77.6 percent of primary energy production in 2017.

It's within this context that, in some quarters, the idea of carbon capture and storage, or CCS, has gained traction.
