Although the use of renewable energy is on the rise, coal and natural gas still represent the majority of the United States energy supply. Even with pollution controls, burning these fossil fuels for energy releases a tremendous amount of carbon dioxide into the atmosphere—in the U.S. alone, coal and natural gas contributed 1,713 million metric tons of CO2, or 98 percent of all CO2 emissions from the electric power sector in 2017.1 In an effort to mitigate these effects, researchers are looking for affordable ways to capture carbon dioxide from power plant exhaust.
