Carbon capture and Storage

  • Atmospheric carbon dioxide measured at NOAA's Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago. In 2016 it is 402.52ppm
  • Carbon capture and storage technology is the most promising technology to significantly decrease CO2 emissions. Nevertheless, it may be possible to use CO2 as a raw material for other industrial uses.
  • The transported CO2 can also be reused in processes such as enhanced oil recovery (EOR) or in the chemical industry, a process sometimes known as carbon capture and utilisation (CCU). CCS can be applied to fossil fuel power plants (coal and gas-fired power stations) and to industrial CO2 -emitting sources such as oil refineries or cement, chemical and steel plants. Rather than being a single technology, CCS is a suite of technologies and processes While some of these have been operated successfully for decades, progress in applying large-scale CCS to power generation globally has been slow (Fig

1)There are several technologies and strategies to capture CO2 from stationary sources:

  • pre-combustion, post-combustion and oxy-fuel
  • Emerging technologies for CO2 capture
  • Chemical looping combustion
  • Hydrate-based separation
  • Calcium looping
  • Partial oxy-combustion
  • Biological CO2 capture
  • Ionic liquid absorption

2)CO2 transport

3)CO2 storage

  • Curbing the Greenhouse Effect by Carbon Dioxide Adsorption with Zeolite 13X
  • Efficient Adsorption of Super Greenhouse Gas (Tetrafluoromethane) in Carbon Nanotubes
  • Exhaust emission factors of greenhouse gases (GHGs) from European road vehicles

My Thoughts

1)By applying these techniques if we use adsorbers as sheets or nanotubes in heavy Traffic roads and junctions to capture and reuse.

2)Methane gas has low lifespan of 12yrs compare to other gases so we have to think about methane reducing.

3)In the part of awareness people try to use bicycles for short distances and avoid long period used vehicles which are creating high pollution. Lets plant more trees.
