Good Article: What is carbon dioxide capture and sequestration

What Carbon dioxide capture and sequestration is

  • CO2 s taken out of the air from plants or factories
  • When the CO2 is stored it is referred to as sequestration
  • CO2 is stored 2 miles underground in amongst porous rock , above this layer is non-porous rock which prevents the CO2 from moving back up to the surface
  • Once the CO2 has been compressed it is usually transported via truck or by using a pipeline
  • A diagram below shows the typical process for carbon capture and sequestration (ccs)
  • CCS is important because it is estimated that power plants that burn fossil fuels can have emissions cut by 80 to 90%
  • CCS can also reduce pollutants cement plantations and natural gas facilities

Bad Article The Surprising Key to Viable Carbon Sequestration: build more highways

  • Humans produce around 40bn (Barn) metric tons of carbon dioxide each year.
  • Coca Cola is trying to solve this problem by using a plastic bottle made from plants unlike the regular plastic made from petroleum. From the years 2009 and 2015 it is estimated that 315,000 metric tons of CO2 were saved.
  • Similar to Coca Cola companies are trying to work out how to reduce carbon emissions. Brent Constantz, CEO of BluePlanet, wants to take the waste from carbon dioxide and make it into limestone.
  • BluePlanet is a building materials company
  • To manufacture limestone they are using Carbon dioxide from a California power plant located at Moss Landing. “The process removes about 90% of the carbon dioxide and combines it with minerals in the water, resulting in the creation of limestone that is composed of about 50% waste carbon dioxide.” (Watson)
  • The power plant at Moss Landing produces 2 million tons of carbon dioxide per year.
  • Another popular building supply, concrete makes up 5% of CO2 globally.
  • BluePlanet is working with Canada to pass a law that states contractors have to use recycled rock when makingĀ roads.
  • According to James Hansen, who was in charge of the Goddard InstituteĀ for Space Studies, stated “Nobody knows where the real tipping points are-the specific points at which global warming will become irreversible.”(Watson) He is referring to the amount of carbon dioxide in the atmosphere
  • In September of 2016 the carbon dioxide in the atmosphere did not go below 400ppm (Parts per million) He thinks the atmosphere needs to have a carbon dioxide level of 350PPM it is hard to say for certain what the magic number is for carbon dioxide in the atmosphere should, be.
