Baking soda 'sponge' to capture carbon

Share it

Scientists in California are testing sponges made with the key ingredient of baking soda as a way of capturing carbon emissions. At the Lawrence Livermore National Laboratory in California, they believe that baking soda could be a key ingredient for curbing the carbon. Exposure of sodium carbonate to CO2 and water creates sodium bicarbonate – otherwise known as baking soda.

One advantage of the microcapsule approach is that recovery of the captured carbon is done by heating the baking soda solution, and that means the scientists get a more pure form of the gas – which increases its value for other industries.

The researchers test the effectiveness of the baking soda materials by soaking them in sparkling water. The baking soda absorbs the carbon bubbles, rapidly turning the water flat.

The scientists believe that the baking soda capsules and sponges could be used in a host of applications, not just at power plants.
