Objectives

What role should GTL technology play in future energy supply in South Africa?

• List of GTL technologies to be considered

• Major characteristics:

Costs

Emissions

Jobs

Water use

GTL technology is now

designed to make diesel

In 2030 a further 4.6 Tcf of gas will be required to meet the 70 000 b/d diesel demand growth.

In 2025 3.3 Tcf of gas will be required to meet 50 000 b/d diesel demand growth.

Conclusions

• South Africa is well positioned to use GTL in the future

• Diesel production by GTL matches local market demand

• GTL technology production costs competitive

At $100 per barrel oil price

$5 per MMBTU gas price

• Sufficient regional gas reserves discovered to meet diesel demand growth post 2020.

• GTL technology designed to use seawater but then needs a coastal location.
