South Korean lab develops oxyfuel CCS

A South Korean state laboratory says it has developed a commercially viable carbon capture system using industrial waste heat that can help power plants cut back on greenhouse gas emissions according to the Yonhap news agency.

"The technology can minimize the drop in efficiency associated with the carbon capture and sequestration process that has prevented power plants from adopting similar systems in the past," the laboratory said.

A normal gas-turbine power plant has an energy efficiency of around 57 percent of input, but incorporating a carbon capture system into the generation process causes numbers to fall to 43-45 percent levels.

Tests using the new system have shown efficiency rising to over 50 percent, which experts say is the minimum needed for the carbon capture system to be commercially viable, KIMM said.
