The U.S. re-joined the Paris climate accord a few months ago, which means – along with 194 other countries — it now has to find ways to seriously curb its greenhouse gas emissions. Many argue that renewable energies such as solar and wind are the way to go. But another path to reduce air pollution involves trapping carbon dioxide (CO₂) as it’s produced, before it can even reach the wider atmosphere.
There are a couple of ways to achieve carbon capture. “Post-combustion carbon capture” is the most straightforward method, and — as the name suggests — this happens after a fossil fuel, such as coal or natural gas, is burned.
