Mechanical Thermal Expression (MTE) for Power Station Efficiency
GREENHOUSE GAS ABATEMENT PROGRAM PROJECT
Project Management: Loy Yang Power Management Pty Ltd
Project Details:
- This research project will help to develop a new technology to reduce greenhouse gas emissions from brown coal. The MTE technology is based on the concept of pre-drying the coal before its use as a fuel in boilers.
- A pilot plant to scale up the application of the MTE technology will be constructed at Loy Yang power generating plant in Victoria.
- MTE is a process that involves heating coal and then applying a mechanical pressure to squeeze the water out from it. The research conducted so far has demonstrated that up to 80% of the water content in Victorian brown coal can be removed through MTE.
- In a conventional boiler plant, part of the fuel is burnt to provide energy to evaporate water from the brown coal. By reducing the water content of brown coal, the MTE technology can substantially increase fuel efficiency and thus reduce greenhouse gas emissions.
GGAP Funding: up to $2.2 million was approved under the GGAP, with matching contribution from the Victorian Government.
Total Project Cost: Approximately $5.6 million.
Expected Greenhouse Gas Abatement: There is no abatement directly attributable to this project. However, there is potential for a significant reduction in greenhouse gas emissions once the MTE technology is applied at an industrial scale.
Note: Carbon dioxide equivalent (CO2-e) is the basis for comparing the warming effect of a greenhouse gas as compared to carbon dioxide and is calculated by multiplying the mass of a greenhouse gas by its global warming potential.
