But it’s very dilute from the point of view of capture,” says Harry Atwater, professor of applied physics and materials science at California Institute of Technology. “In the atmosphere, we have carbon dioxide that we’re worried about that’s significant from the point of view of affecting the radiative forcing and climate warming. Meanwhile, the concentration of carbon dioxide in the general atmosphere is around 400 to 450 ppm (parts per million), or about 0.04 percent. However, the flue gas coming out of a smokestack from the chimney of a power plant or industrial facility carries a much heftier amount of carbon, at around 10 to 15 percent carbon dioxide. Carbon captureĬarbon capture most commonly refers to the process of removing carbon dioxide from various sources like the smokestacks of power plants running on fossil fuels like coal, oil, or gas, as well as from manufacturing and production facilities.Ĭapture also refers to removing carbon dioxide directly from the atmosphere, called Carbon Dioxide Removal (CDR), or Direct Air Capture (DAC). Here’s a debrief on what these terms mean, the current state of technology, and what they would look like in practice. There’s a lot of industry talk about whether applying counter carbon technologies and techniques like carbon storage, carbon capture, carbon conversion, and carbon sequestration could make a sizable impact in removing carbon dioxide, the most abundant greenhouse gas emitted today.
