Carbon Capture in Hawaii (Code Green)
from ThinkTech Hawaii Hosted by Jay Fidell
Hawaii Joins the Carbon Capture Crusade. The host for this show is Howard Wiig. The guest is Christie Gamble. Carbon dioxide emissions are the prime cause of climate change. The most effective action is to remove CO2 from the atmosphere and transform it into a useful product that lasts for centuries. Some cement companies are injecting liquid CO2 into concrete mixing batches where it mineralizes into calcium carbonate, a strong stable compound that hardens concrete. (Interestingly, calcium carbonate may be taken as a supplement to harden bones, and is closely related to baking soda.) The CO2-strengthened concrete reduces the volume needed to achieve required strengths, resulting in a lower carbon footprint and lowering transport weight and volume. CO2-stregthened concrete also reduces the "cure time" needed to harden the concrete mix to the required moisture content, reducing construction time. CO2 can comprise up to 20% of the volume of concrete. Energy CO2 has already been removed by one carbon concrete company to remove from the atmosphere CO2 equivalent to 53 million cars.
