Carbon capture process produces hydrogen and construction materials

QUT scientists have developed a process to capture carbon dioxide from the air into water and store it as non-toxic calcium carbonate (chalk), a key ingredient for cement production and other products, all potentially powered by solar or wind energy.

PhD researcher Olawale Oloye and Professor Anthony O’Mullane from the QUT Centre for Materials Science and the QUT Centre for Clean Energy Technologies and Practices developed the electrochemical capture and conversion of carbon dioxide process which also generates hydrogen and a host of useable by-products.

“This process involves the capture of CO2 by its reaction with an alkaline solution produced on demand, to form solid carbonate products which can be used, for example, as construction materials, thereby keeping carbon dioxide out of the atmosphere,” Professor O’Mullane said.
