Female scientist at forefront of carbon dioxide capture
Print Edition
While the others rack their brains to work out a way to cut carbon emissions, 40-year-old female scientist Li Jia is working on catching and collecting carbon dioxide in the air.
“Sometimes the young generation may think the current climate problems are caused by the behaviors of the elder generation, so what we are doing is to make it up to them?” Li told Shanghai Daily. “Direct air capture relieves the damage that has already been done to the air.
“The large emission sources include power plants, cement plants, chemical factories and steel factories. The amount of carbon dioxide they emit in a year ranges from 1 to 5 million tons. Some can even reach nearly 10 million tons,” she explained.
“What we do is use a chemical approach to reduce the carbon dioxide. We use a solution to react with the carbon dioxide in the gas they emit that absorbs the carbon dioxide.”
After refinement, the concentration of carbon dioxide is very high and can be collected for transport and buried.
Last October, President Xi Jinping visited the Shengli Oilfield in Shandong Province. During the visit, he inspected a carbon dioxide storage project that brought a new boom to the industry.
“Currently, many large state-run enterprises, such as power and petrochemical companies, have their own carbon capture, utilization and storage projects. We are happy with that,” Li pointed out.
