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

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

Is there any Solution that helps shape the future of our

coasts?

Yes and

it is Sriya’s “CS2” Process

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

Sea Water has Ca & Mg and other high value minerals

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

“CS2”: Very Flexible Process

“CS2” process is extremely flexible and produces variety of products with different colors and textures

Sriya Group IP: 6 Patents/Applns.

1. Supported Liquid Membranes: 2 US Patents2. Biomass Cracking to Sugars and Lignin: US

Patent and PCT Applied3. Lignin enabled “Combustion Synthesis” US

Patent4. CS2 (In Process)5. SCCO2 Power using biomass and solar (US

Prov. Filed)6. Nano Urea to enhance Biomass and grains

for a 2nd Food + Energy Revolution (US Patent Filed)

Sriya CS2 Positives

50% lower Capex and 30-50% lower Opex

30-50% lower C and GHG Footprint

Positive heat energy and 50% lower power

Multi products = low to minimal risks

Sriya’s CS2: “Shapes the future of our coasts”

Clean, Free Drinking Water for its citizens

Green Cement and concrete with no quarry and mining

Free Green Power and high value chemicals

100% CO2 Sequestration = “Sustainability +ve”

NO FOSSIL FUELS USED IN THE PROCESS (eco-friendly)

(versatility, eco-friendly and diversity positive solution)

Sriya Ready to implement quickly

Industry supportive (Holcim, BASF)

DOE & EPA Supportive

3 US University partners

Design Complete, Pilot location identified

$2.5M from Kleiner Perkins in 2008; $10M Capital being raised

Seeking Host City and local support

SGE - Savannah “CS2” Opportunity

Become the 1st city in the world to provide

◦ Cheapest drinking water and eliminate thirst

◦ Free green power, green cement and green chemicals

Start 2nd Green Revolution with a proven technology and great

partners like Holcim & BASF

100% CO2 Sequestering with existing power plant exhausts.

Cement GHG +VE

Sriya Pilot Plant

Sriya CS2 Process Summary100 million GPD sea water desalination plant

will produce:

◦ 80 MGD fresh water.

◦ 3000 TPD brine for NaOH, HCL and Chlorine,

◦ 108 TPD cement
