Presently, coal-fired power plants (From which we get most of our electricity) use special binding liquids that capture carbon dioxide from the harmful acid gases emitted - A process which requires a lot of energy and water.

The Department of Energy's Pacific Northwest National Laboratory have come up with a solution to capture harmful gases in a more energy-efficient way using a mixture of water and monoethanolamine.

Monoethanolamine is a basic organic molecule that grabs and stores two times the amount of carbon dioxide and other acid gases such as sulfur dioxide compared to conventional liquids.

The process is known as "Reversible Acid Gas Capture" which directly replaces current methods to capture more gases without using water and less energy. The liquid is completely recyclable and the captured gases can be released quite easily for safe disposal.
