Fossil Fuel Road Maps• Coal Road Map
• Joint Project – DoE and SA Industry• Phase I Ready for Release• Phase Final – Scheduled Mid-2012
• Liquid Fuels R&D Road Map• SANEDI Internal Framework Study Underway• Scheduled mid-2012
• Gas Road R&D Map• SANEDI Internal Framework Study Underway• Scheduled mid-2012
Road Maps include an R&D gaps analysis to indicate where development is needed
Coal is generally known - Oil/Gas unclear

Energy & Environment
CCS is a Flagship Programme of the National Climate Change Response White Paper

Principle
Extract Carbon Dioxide from Fossil Fuel UseElectricity Generation Stations [~12% CO2]
Synthetic Fuel Plants [~95% CO2]etc
Inject Carbon Dioxide back into Geological Formations [from whence the fossil fuel came]

Permanency
Permanency Stages of Trapped CO2:
Structural Trapping Overlaying cap rock
Residual Trapping Tiny pores in rock – capillary pressure of water
Solubility Trapping Dissolve in saline water
Mineral Trapping React chemically with surrounding rocks – become part of rock

Technology Development
It is not a question as to whether the technology works
We know it worksBeen operating at many sites for decades
It is a scale-up issue

Potential for Carbon Dioxide Storage in South Africa
Atlas indicated a Storage Potential: 150 Giga tonnes At an “effective level” 98% off-shore
Need: 4 Giga tonnes To store 40 million tonnes For 100 years

Projects Currently Underway
• Scoping Study for Test Injection• Regulatory Requirements for Test Injection [Europe Aid/SACCCS Funded]• Zululand Basin Storage Potential [UK Funded]• Algoa Basin Storage Potential [Europe Aid/SACCCS Funded]• Geological Modelling of Storage Sites [Europe Aid/SACCCS funded]• Financial Opportunities for CCS in South Africa [Europe Aid/SACCCS funded]• Public Outreach Determination [World Bank Funded]• Definition of “Capture Readiness” Determination• Capacity Building:
• Five post-graduate bursaries• Post-primary Schools Science Expo
• Joint Industry Project – Techno-Economic Study [SACCCS/World Bank]• Collateral Benefits – Job Creation/preservation, industry development [CSLF]• CCS Week [SACCCSA/CSLF]
• The Department of Energy: Developing a Carbon Capture and StorageRegulatory Framework [World bank Funding]
