Coldry: Black Coal Equivalent (BCE)

Coldry is a black coal equivalent, meaning its net energy value is similar in range to that of many black coals.

Key Features

• Exponentially enhanced net energy content increased up to 285% for 60% moisture Victorian La Trobe Valley Lignite
• The self-ignition tendencies of typical Lignite is greatly reduced to that of normal Black Coals
• Accumulation of up to 90% less Ash than typical black coal, increasing operational efficiencies and reducing removal costs
• Immediately deployable in existing brown coal boilers (10% to 20% of total energy mix), decreasing coal requirements (7% to 14%), reducing emissions (6% to 11%) and reducing ash accumulation (2% to 4%)
• Provides Business Case drivers for introduction of modernised supercritical boilers, decreasing coal requirement (up to 48%), reducing CO₂ emissions (up to 40%) and reducing ash accumulation (up to 32%)
• Retains the CTL and Gasification advantages of lower rank coals, without the complexities associated with high moisture levels

Stable

Testing by University of Queensland places Coldry in the same ‘sponaneous combustion’ risk range as thermal (black) coals currently exported from Queensland and NSW. The Coldry process changes the physical and chemical structure to the point it no longer has the same ‘high-risk’ of spontaneously combusting as brown coal.

Valuable

As a black coal equivalent, the product is valuable and will enjoy the higher prices paid for black coal under certain market conditions. Also, the product attracts lower transportation costs in terms of energy per unit of mass, due to the removal of unnecessary water.

Versatile

The product is versatile and can serve as a valuable feed stock for power generation including subcritical, supercritical and ultra supercritical black coal boilers, and gasification based chemical and fertiliser production processes, particularly in its rapid dry form.

Coldry pellets can be used in local black coal power plants co-located on brown coal mines or transported to remote black coal power plants, with co-located production under fast drying conditions resulting in stronger production economics.
