Capturing carbon dioxide from power plants is, at least theoretically, a good way to reduce one of the top gases that contributes to climate change.
But in reality, it’s hard – and so far, inefficient.
Carbon capture pilot projects across the country have come and gone. But even though it’s technically over, the pilot project at one power plant in Central Kentucky remains. There, University of Kentucky researchers continue to test technology they say is cheaper and more efficient than others being tested around the country.
At Louisville Gas & Electric and Kentucky Utilities’ E.W. Brown Plant, near Danville, there’s a six-story open structure attached to one of the plant’s units. It’s a scaffolding-like maze of yellow, blue and silver metal.
Kunlei Liu stands under it, wearing a hardhat and safety glasses, ready to explain the intricate workings of the device.
