HCGT Technology Overview

HCGT Electricity Plant

Typical 10MWh HCGT Electricity Plant configuration

HCGT uses coal waste, ventilated air methane (VAM) or Biomass to produce electricity.

HCGT 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, turn what is currently regarded as waste into electricity.

HCGT will fill a gap in the power generation market which large-scale power generators cannot.

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. The key features of the HCGT technology are:

• 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

HCGT provides the following Operational benefits

• Handles a wide range of feed material
• Consistent level of electricity production
• Minimal maintenance
• Local skills for routine operation and maintenance
• Environmental benefits
• Remediate waste coal
• 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 on power and waste coal management costs.

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.
