Why CCS?

If the rise in global temperatures is to be limited to 2 degrees Celsius in line with global emissions reduction targets, all nations including Australia must meet their emissions reduction targets. To avoid economic disruption, it is essential that this is done in a way that maintains reliability and affordability while reducing emissions.

Coal-fired power plants can supply reliable, low-cost energy, however their carbon dioxide (CO2) emissions need to be reduced.

Renewable energy sources such as wind and solar are clean sources of energy but can cause instability in the power grid due to the variability of the wind and sun. While natural gas has lower (but still significant) emissions than coal and can provide stable energy supply, its price continues to rise.

LET Australia is investing in minimising emissions from coal-fired power production and developing carbon capture and storage (CCS) to support cost-effective, reliable and cleaner energy.

THE ROLE OF CCS IN ACHIEVING A LOW-EMISSIONS FUTURE

While each electricity-generating technology brings its own advantages and disadvantages, diversity of supply using a range of low- and zero-emissions technologies is required to achieve energy security through reliable, affordable, and clean energy.

No single technology can meet this challenge. Coal with CCS offers several valuable attributes that other technologies cannot provide.

Coal plants with CCS can achieve very deep decarbonisation of the electricity grid, reducing emissions while maintaining grid stability.

Coal with CCS is a technology that can provide essential grid stability services over all time frames from the split-second to the seasonal in a predictable and controlled way, while reducing emissions to very low levels at a competitive cost.
