How it Works
Natural Storage For CO2
Algae filtering systems, natural processes for carbon sequestration, safely store captured CO2 in carbonate formations.
The intent for combustion carbon capture and safe storage (CCSS) is to provide one additional segment to the already established array of continuous carbon sinks perfected over millions of years.
This may be an advantage in the face of uncertainty presented by enhanced oil recovery (EOR). EOR is favored now by established energy companies for carbon sequestration. This is not a good choice considering safety and cost.
Carbonate formations on the other hand, allow dissolved CO2 to be safely stored as evidenced by massive world-wide chalk formations which may be like a kind of carbon microbiology maintenance effort by ancient phytoplankton. Except it's still happening.
What's needed now is to borrow from the same strategy nature has perfected over millions of years for a rapid and frequent CO2 capture of our waste beside the natural and continuous methods on-going.
Our focus is on atmospheric CO2 and combustion emissions. Specifically, collection methods described previously - filtering methods not dependent on any one shape, or single filter placement.
Treated and structured filters with differences that can achieve similar results for limited, isolated applications, or scaled-up for waste treatment plants. Our focus today is:
- Transportation (tailpipe & atmospheric) - CO2 capture products (on-going),
- Methane engine electricity generators - CO2 capture and re-use (proposed).
Biogas fuel or farm methane from anaerobic digesters, has a typical composition of:
- methane (CH4) 60%,
- carbon dioxide (CO2) 30%,
- nitrogen (N2) 0-10%,
- hydrogen (H2) 0-1%,
- hydrogen sulfide (H2S) 0-3%, and
- oxygen (O2) 0-2%.
Biogas operations are established and sensible additions to farms both small or large in many parts of the world. The engine fuel runs electric generators. Not only is electricity a product, biogas is used for heating and cooking. Also, leftover sludge is de-watered and sold as animal bedding material.
Another important product of biogas digesters is the growing of Chlorella algae from available effluent. Chlorella are oil-containing plants (algepower.com), for local (Vermont) biofuel oil production and distribution sites.
Carbon capture filters from IEC may help with this renewable energy alternative.
Carbon filtration from methane combustion and reusing the captured CO2 is designed to create additional value for algae farm production where needed.
How effectively can this foreseeable technology - carbon capture - substitute for ecosystem services? Specifically, can we provide KOH to combustion exhaust to drive a reaction that would not normally occur, then dissolve the resulting KHCO3 into water to grow food or fuel with algae?
