Srinivas Kilambi proposes a new "CS2 Process" that uses sea water to produce drinking water, green cement, and green power in a sustainable way. The process sequesters 100% of carbon dioxide in the production of limestone from sea water. It then uses this limestone to produce cement and energy, avoiding the need for quarries or mines. A 100 million gallon per day sea water plant could produce 80 million gallons of fresh water, cement, green chemicals and power while eliminating fossil fuel usage and greenhouse gas emissions through carbon sequestration. The process has many benefits over conventional methods and Kilambi is seeking partners to build a pilot plant.

 Brian Curtis – Former Calera Executive
 Dr. N. Neiliyath, Clarkson University
 Ken Postle, Global Cement Expert

 Kamal Gunsagar: Sriya Innovations, Co-Founder

4. Why Water & Cement?
 Water is the most used commodity on
earth followed by cement
 Cement Industry consumes ~2% of
world’s energy and produces 6-8% of
world’s GHGs
 ~40% of world’s has drought/arid areas
even though 70% of earth is sea water

5. Current Technologies &
Limitations
Water Desalination
 Current Tech: RO &
Distillation
 Energy/Capex Intensive
 $0.5-1/g water: Not Viable
Cement Production
 Tech. same for >2000
years (since Romans)
 High Energy and Capex.
 Very High CO2/GHGs/Hg

6. Is there any Solution that
helps shape the future of our
coasts?
Yes and
it is Sriya’s “CS2” Process

7. CS2 = Comb. Syn. + C
Sequestration
1. CO2 sequestration in sea water = natural limestone
2. Sea water limestone to green (cement + energy)
3. Green power from surplus waste heat in a turbine
4. Distill sea water into potable water & brine
5. Brine to green chemicals and sea salt

8. Sea Water has Ca & Mg and
other high value minerals

10. Unique“CS2” Process
 Conventional OPC technology: 1500 C , 30-40 min in a kiln
 SGM’s “CS2” technology 100 C, 20-40 s; no kiln:
◦ Instant cooling (20-30% lower energy needs)
◦ Eliminates hard crushing: 50% power reduction
 55-70% power efficiency
 Exhaust CO2 sequestered in sea water to limestone
 High value metals oxides from sea water = Very High Profits
