HiPCO(The High Pressure Carbon Monoxide Process)
The process of removing carbon from the atmosphere and depositing it in a reservoir.
Geo-engineering technique for long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming.
Way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.

Shortcomings of current process
1. Activated carbon adsorption
2. Direct combustion
3. Catalytic oxidation
4. Ozone oxidation
1. Inconsistent efficiency
Efficiency sharply drops when it works for long time.
It happens as nutrients for microorganisms are insufficient.
2. Unequal growth of microorganisms
Efficiency decreases, hard to handle when factors change suddenly
