CCUS technology is constantly being improved. Various substances have been used to absorb carbon dioxide. The most common is sodium bicarbonate (commonly known as baking soda).
        Now Virginia Commonwealth University has pioneered the use of formic acid as an effective catalyst for the thermochemical conversion of carbon dioxide. Formic acid has many advantages – it is a low toxicity liquid that is easy to transport and store at room temperature.
       Dr. Shiv N. Khanna, Chairman and Professor of Physics at the VCU College of Arts and Sciences, explained, “Catalytic conversion of CO2 to beneficial chemicals such as formic acid (HCOOH) is a cost-effective alternative strategy to mitigate the harmful effects of carbon dioxide.”
