Using seawater to cut emissions
Technology that can cut CO2 emissions from industry, power stations and shipping has been developed by a South Australian company.
The technology, developed by Sustainable World Technologies (SWT), involves converting CO2 into stable compounds, such as calcium carbonate and magnesium carbonate, using an electrochemical system.
The process combines seawater with exhaust gases, permanently converting the CO2 into the stable carbonates.
"Climate change is one of the most significant issues confronting us, and Australia can make a difference globally by advancing technologies such as these," said SWT managing director, Rudy Gomez.
The company said no chemicals were added to the process and the carbonates produced were the same as those found naturally in coral reefs and limestone rocks.
Initial trials of the system had returned 30% reductions in CO2 emissions, according to SWT.
"SWT's technology is a permanent CO2 sequestration solution that avoids the risk of CO2 returning to the atmosphere.
"I am confident that with further research and development we will have a simple, low-cost system to reduce CO2 emissions by more than 30%,” Gomez said.
