Open cut & underground coal mining operations generate significant amounts of waste gas (primarily methane). Traditionally, this potent greenhouse gas has been vented or flared, however next generation technology now means this waste gas can be captured and transformed into a valuable resource for power generation. 

These solutions encompass: 

1. Gas Capture Systems
2. Gas Treatment
3. Gas Power Generation
4. Hybrid Power Generation

Capturing Methane: From Waste to Resource

 In open cut & underground coal mines methane tends to escape into the atmosphere. This poses a dual challenge: it contributes to global warming (since methane is 25 times more potent than carbon dioxide), and it represents a lost energy opportunity. Through the installation of methane capture systems, such as strategically placed wells and venting systems, mining operators can prevent methane from escaping and instead direct it to a central processing point.

Gas Treatment and Power Generation by Eneraque

Once captured, the methane must be treated to remove impurities such as dust and other contaminants that could impact the efficiency and safety of the power generation process. Eneraque specialises in designing and implementing gas drainage & treatment systems that prepare the waste gas for efficient combustion.

Eneraque’s advanced power generation systems convert the treated methane into electricity using gas engines or turbines. The process works by burning the methane to generate mechanical energy, which is then transformed into electrical energy. This electricity can be used on-site to power mining operations or exported to the grid, providing an additional revenue stream for the mine.

Reduced emissions. Improved commercial outcomes. 

By capturing methane and preventing its release into the atmosphere, mining companies can significantly reduce their greenhouse gas emissions. Eneraque’s solutions also contribute to compliance with stringent environmental regulations, helping mines meet their sustainability targets.

Using waste gas for power generation also offers economic advantages. Mining companies can reduce their reliance on external energy sources, lower their operational costs, and in some cases, generate additional income by selling excess electricity back to the grid.
