Changing Industrial Combustion
- Modifying industrial carbon transfers helps mitigate the impacts of climate change
- Some of the initiatives include :
- Target setting to reduce greenhouse gas emissions globally
- Switching to renewable sources of energy on a national scale
- 'Capturing' carbon emissions and/or storing or burying them (sequestration) to reduce industrial emissions
- Reduction in global deforestation
- Changes to land use
- Carbon capture and storage (CCS) uses technology to capture CO2 emissions
- They can catch 90% of emissions, which could cut global carbon emissions by 19%
- CCS chain consists of 3 parts:
- Capturing - separation of CO2 from gasses produced
- Transporting - pumping CO2 through a pipeline or ship to storage locations
- Storing CO2 - in places such as deep mines, depleted oil and gas fields, deep oceans and saline aquifers
- CCS technology can be used for hydraulic fracturing (fracking) to extract oil and gas by pumping the CO2 into the ground, with the increased pressure forcing oil and gas out and leaving the CO2 behind
- CO2 can be stored directly in sedimentary rocks by turning it into a high pressure liquid (supercritical CO2) and injecting it into the rock
- Over and underlying impermeable rock act as a geochemical trapping mechanism, preventing CO2 escaping to the surface
