  1. Sequestering Carbon Dioxide in the Built Environment JUCCCE China Energy Forum Brian Curtis Corporate Development Calera Corporation November 10th, 2008

  2. Calera’s Solution Capture CO2 and convert it into green building materials

  3. Calera Process Clean Air (reduced or zero CO2) Demineralized Water (stripped of Ca & Mg) Flue gas Calera Power Cooling seawater (or alternative direct source) Cooling seawater Green Cement

  4. Calera Process as Biomimicry Calera’s process is similar to coral reef formation Seawater absorbs CO2 Coral process = + minerals CO2 Coral

  5. Carbon Capturing Materials “Being less bad is not good enough” + Normal Concrete With 50% Fly Ash Carbon Footprint Carbon Capturing Concrete -

  6. Calera’s Pilot Facility CO2 Source: Largest Power Provider in California Moss Landing, CA >1000 MW base load >1500 MW peaking Natural Gas >3.4 million tons CO2 per year Source: EPA (2007)

  7. Green Cement for a Blue Planet “Calera, a game changer” Carl Pope, President of the Sierra Club

  8. Carbon Capture (80% cost of CCS) Lab Testing Pilot Testing Research Demo Testing Commercial Maturity Level Ammonia Alstom (Chilled) – 20$/tCO2 Powerspan (ECO2)– 11$/tCO2 Membranes Carbozyme CO2Solution Post-Combustion Amine Scrubbing Mitsubishi MHI (KM CDR) Fluor (Econamine) Cansolv Sorbents/Solvents GreenFuel (Algae) Siemens Siemens 47-50$/tCO2 IGCC Membranes Pre-Combustion GE Energy Mitsubishi MHI E-Gas Shell Solid Sorbents Retrofit New Selexol Rectisol 36-67$ 16-30$ Oxy-Combustion Alstom Babcock & Wilcox Hitachi 32$/tCO2 Sources: URS Washington Division, CCS Presentation, IEA GHG R&D Programme, EERC Research Center

  9. Carbon Sequestration (20% cost of CCS) Transport Injection Monitoring Also required 5-70$/tCO2 0.1-0.3$/tCO2 10-15$/tCO2 Proven Research Demo Testing Commercial Maturity Level Ocean storage (5,000Gt) 4.5-30$/tCO2 Depleted oil & gas field EOR (900-1,200Gt) Un-mineable coal beds Potential Benefits Geologic Storage Saline aquifers (1,000Gt) Declining oil fields (15Gt) Mineral storage 50-100$/tCO2 0.5-8$/tCO2 0.5-8$/tCO2 Sources: IPCC Societe Generale, CapGemini CCS Presentation, McKinsey, EERC
