what are hele technologies hele high efficiency low emissions
What are HELE technologies? (HELE=high Efficiency Low Emissions)

HELE

CCS

*Efficiency improvement*

Reduce non-GHG emissions

Reduce CO2emissions

Efficiency improvement reduces specific fuel consumption and also reduces specific pollutant emissions.

age distribution of existing power plants
Age distribution of existing power plants

Ageing infrastructure is the challenge in many OECD countries. Emerging economies have a growing demand for electricity.

improve efficiency then deploy ccs
Improve efficiency, then deploy CCS

Decrease generation from subcritical

Install CCS*on plants over supercritical

Increase generation from high-efficiency technology (SC or better)

*CCS (Post-combustion, Oxyfuel, Pre-combustion CO2 capture)

Subcritical

Global coal-fired electricity generation (TWh)

HELE Plants with CCS*

USC

IGCC

Supercritical

* CCS fitted to SC (or better) units.

but deep cuts

only by CCS

Data for hard coal-fired power plants from VGB 2007; data for lignite plants from C Henderson, IEA Clean Coal Centre; efficiencies are LHV,net

Energy Efficiency makes big change but deep cuts of CO2 emission can be done only by Carbon Capture and Storage (CCS)
