Reduction of CO2 emissions from 2010 in the 2DS

Decreasing CO2 intensity factor – driven by technology development

Reducing electricity from coal-fired power generation –driven by policy and regulation

Technology improvement coupled with targeted policy and regulation are essential to realise the 2DS target in 2050.

IGCC+CCS may be cost competitive

With the latest 1500C-class gas turbines, efficiencies of 50% (LHV, net) may be achievable, with cost-competitiveness will depend on sufficient numbers of plants being deployed.

Recommended actions for the near term

By 2020, CO2 emissions from coal-fired power generation must

already have peaked to be consistent with the 2DS.

Greater efficiencies must be achieved in the power generation

sector.

Deploying supercritical and ultra-supercritical technologies, both available

now, will be important.

Even higher efficiencies will be achieved as A-USC and more advanced

IGCC become available.

Power generation from low-grade coals, such as lignite, can be

much more efficient.

CCS must be developed and demonstrated rapidly if it is to be

deployed at a scale sufficient to achieve the 2DS.
