CoalSwitch®

Biomass has a key role in future renewable energy sourcing and energy security

…but white pellet is an old technology and is falling short on environmental efficiency

CoalSwitch® has substantial advantages over existing biomass:

  • Uses waste biomass residuals as feedstock
  • Provides greater energy and bulk density making it more cost efficient
  • Ability to co-fire with coal means suitable for use in different industries
  • Minimal capex required to convert existing fossil fuel operators

AEG has proven the industrial process, created a proven product and is accelerating customer interest

 

Key advantages

CoalSwitch® is superior to other types of renewable biomass pellets, with proven performance benefits.

VERSATILE

CoalSwitch® removes substantially all soluble minerals
Focussed exclusively on using wood waste residuals as feedstock.

A GREENER ALTERNATIVE

CoalSwitch® is a sulphur free, carbon neutral alternative that can be either blended with coal at the conveyor or supplant coal entirely

HYDROPHOBIC

It is hydrophobic so does not require special and expensive storage facilities

EFFICIENT

CoalSwitch® can be co-fired with coal in existing coal-fired power plants without the need for significant capex

Tested and Proven

CoalSwitch® has been tested and proven to be an ideal replacement to coal and other biomass pellets.

AEG initiated an independent combustion testing program, to be conducted on CoalSwitch® fuel in Utah, which was carried out in partnership with Brigham Young University. The findings were better than expected, proving the Company’s theory that CoalSwitch® has a number of important benefits:

Cost efficiencies identified in the milling of CoalSwitch®

The primary measurements of interest were the power requirements of the bowl motor and the ability to blend both CoalSwitch® and coal. The test results confirm that CoalSwitch® can be milled in an unmodified mill with only small changes required to the mill settings.

Further, there was also a material reduction in mill power requirements when milling the CoalSwitch® fuel compared to the milling of pure coal or biomass blended fuels.

CoalSwitch® has 12.9% higher heating value than white pellets

During combustion testing, the observed heating value of CoalSwitch® fuels of no less than 9,313 BTU/lb, which represents a 12.9% premium to traditional white pellets currently produced for the market by the Company’s competitors, which underpins the economic value of CoalSwitch®.

The test data also provided that with a mix of 75% coal and 25% CoalSwitch®, the heating value was 11,807 BTU/lb, representing a 7% drop from normal coal burning values.

Use of CoalSwitch® reduced ash by up to 77% vs coal

The tests showed significant reduction of ash deposition when CoalSwitch® was used. When used on its own, CoalSwitch® produced 77% less ash than coal. CoalSwitch® / coal blends also resulted in a significant reduction of ash deposition, with higher CoalSwitch® ratios producing less ash.

Use of CoalSwitch® reduced NOx emissions by 20% vs coal

The tests showed significant reduction of NOx emissions when CoalSwitch® was used. When used on its own, CoalSwitch® generated 20% less NOx than coal. CoalSwitch® / coal blends also resulted in a reduction of NOx emissions, with higher CoalSwitch® blended ratios producing less NOx.

Use of CoalSwitch® reduced sulphur dioxide emissions by 60% vs coal

The tests showed that burning pure CoalSwitch® produced significantly less sulphur dioxide than burning coal. Blended ratios also produced significant reductions in sulphur dioxide emissions.

CoalSwitch® is fully sustainable throughout its lifecycle

  • FORESTRY

    We utilize residual product that would otherwise rot on the forest floor
