Developed and perfected by the Australian Mining & Fuel Research Institute (CSIRO)

Significantly reduce fugitive gas emissions and save millions on waste coal management.

Use coal waste, ventilated air methane or biomass to produce electricity.

Uses Ion Volalite Coal.

HYBRID COAL & GAS TURBINE (HCGT) TECHNOLOGY

  • Hybrid Coal Gas Turbine Technology can significantly reduce fugitive gas emissions from underground coal mines and potentially save the coal mining industry millions of dollars
    annually in reduced expenditure for managing waste coal.

  • The HCGT process involves burning gas, waste coal or biomass in a rotating kiln to produce hot exhaust gases which in turn pass through a specially adapted heat exchanger to produce steam, the steam spins the turbine to produce electricity.

  • HCGT can use low quality energy sources, high sulphur and high ash content coal, tailings, lignite, biomass or municipal waste as its fuel to generate power and turn what’s currently regarded as waste, into electricity.

HCGT fills a gap in the power generation arket that large-scale power generators can’t.

  • The intellectual property contained within the system is
    predominantly around the combustion process where the combustion gases are manipulated in a way that ensures continuous combustion whereas other systems would lose their capability of burning these fuels.

  • A typical HCGT system is 5 MWh to 30 MWh package.
    The system is purpose designed for each project application. A typical system is very economical and highly competitive with large power stations.

  • The HCGT can utilize biomass as a fuel source, such as sugar cane waste or wood chip waste from milling operations

Key Features:

  • 5-30MWh electrical output

  • Utilises waste products for fuel

  • Destroys methane at the sub-combustible concentrations in mine vent air

  • Stable operation with variable and low quality fuels
    (including biomass)

  • Based on proven mainstream technology

  • Economically viable and sustainable

  • Able to satisfy qualification
    requirements for greenhouse
    gas trading schemes

Environmental Benefits

  • Remediate waste coal. (Rehabilitation of dumps)

  • Reduces potential for Acid Mine Drainage

  • Up to 30% reduction in waste materials handling and cost

  • Co-generation potential, greenhouse gas abatement credits

    HCGT technology will significantly reduce the environmental impacts of coal mining by lowering fugitive methane emissions from underground mines and reducing acid run-off and gaseous emissions from waste coal stockpiles. At the same time it will deliver potentially significant savings

Operational Benefits

  • Handles a wide range of feed material

  • Consistent level of electricity production

  • Minimal maintenance

  • Local skills for routine operation and maintenance

Cost Competitiveness

  • Made to last 30 years

  • Competitive cost per kilowatt output
    (independently assessed)

  • Low Cost Electricity production

  • Co-Generation potential, energy savings

Typical Applications

  • Coarse Waste Coal
  • Fine Waste Coal
  • Ventilation Air Methane
  • Coal Drainage Methane
  • Mine operations
  • Safe Return of waste to environment

    The majority of Plant components are “off the shelf” which means that they are robust, reliable and low risk in delivery for the company and/or project owners.
