Reducing greenhouse gas emissions with a more effective carbon capture method

"High capacity MgO sorbent for CO 2 capture at moderate temperature promoted by alkali metal nitrate"

Capturing carbon dioxide (CO2) emissions from power plants and various industries may play an important role in reducing greenhouse gas emissions in the future. However, materials currently recovering carbon dioxide, such as chimneys, require less capacity or extremely high temperatures for operation. Scientists are progressing towards a more efficient alternative that is described in ACS material chemistry.

T. Alan Hatton and colleagues point out that industries and governments are paying more and more attention to renewable energy such as wind and sunlight, while in the near future the world will rely on fossil fuels. According to the International Energy Agency, burning fossil fuels will emit more than 3 billion tons of carbon dioxide annually. This is a major greenhouse gas. Some solid systems, such as zeolites designed to capture these emissions, are sensitive to water in the gas stream. Others like clay and metal oxides have to be heated to over 900 degrees F, which requires a lot of energy. Hatton's team wants to find ways to reduce the energy demand of the latter strategy

Researchers have studied new materials based on magnesium oxide (MgO) that capture more carbon at much lower temperatures than many other materials studied. They discovered that coating MgO particles with a material called alkali metal nitrate increases the amount of carbon dioxide that the material can absorb by more than 10 times. For a given volume, the amount of carbon dioxide captured by MgO (2 to 10 times) is much higher than in other systems. This means less equipment requirements and lower plant costs. In addition, the particles themselves are easy to manufacture with low cost materials.

Pores combine the need to reduce greenhouse gas emissions with existing technologies to create garments that reduce carbon emissions. This type of clothing will give environmental responsibility to the person wearing it. When I put on clothes, I absorb CO 2. After wearing several times the carbon can be removed by a reasonable wind turbine sized machine that immerses the laundry under liquid that can capture and hold the carbon. The owner of the garment can then bring the liquid to the nearby carbon sequestration or carbon recycling site and turn it into building material.

Due to global warming, BP and its competitors are seeking ways to reduce greenhouse gas emissions. Carbon capture is a common practice in companies in this industry. Carbon Capture focuses on the recovery of waste carbon dioxide from sources such as waste-rich fossil fuel power plants. Once carbon waste is captured, it is transported to a storage location that can not be destroyed by entering the atmosphere (Sadler, T., 2013. paragraph 7). The Keystone Pipeline is another way that technology helps the United States achieve energy and independence. The Keystone pipeline ends in Texas from the Midwest to the Alberta in Canada. The purpose of the keystone pipeline project is to prove that all US oil producers enter the refinery that will become the biggest supplier to the Middle East over the long term (Kalen, S.2012.para 2).
