CONSOL Energy and Verdeo Group to Develop First Large Coal Mine Ventilation Air Methane Abatement Project in West Virginia

    PITTSBURGH  -- CONSOL Energy Inc. has joined with Verdeo Group, Inc., to develop the first project to destroy ventilation air methane ("VAM") emissions at an active West Virginia coal mine.

    The project, which will be located at CONSOL's McElroy Mine near Glen Easton in Marshall County, will demonstrate significant reductions of emissions of methane -- a potent greenhouse gas ("GHG") -- in a safe and proven manner, and without any impact on mine operations or production. It will be the first time the technology will be deployed at an active coal mine in West Virginia, and among the largest such projects of its kind in the U.S. to date.

    "Companies will require a wide range of tools and incentives to effectively reduce GHG emissions," said Steve Winberg, CONSOL's Vice President of Research and Development. "CONSOL Energy has committed to utilize as much of its coal mine methane resources as possible. This project will allow us to abate a dilute source of methane that has no commercial value and would otherwise be vented into the atmosphere."

    Methane gas is inherent in coal seams and is liberated during the mining process. Coal mines control underground methane emissions through the use of ventilation systems, which circulate large quantities of fresh air through the mine to dilute the methane, and then exhaust the VAM to the surface of the mine and to the atmosphere. According to the U.S. Environmental Protection Agency, VAM represents the largest source of GHG emissions from U.S. coal mines.

    The project will utilize regenerative thermal oxidation ("RTO") technology to destroy the GHG emissions from the McElroy Mine. RTO technology has been successfully deployed in industrial process applications for many decades and this project will test the ability to use the equipment at a commercial scale in the mining sector. To date, several technology installations have been employed in the U.S. at facilities, including a coal mine, that fall under the jurisdiction of the Mine Safety and Health Administration.

    "This project is a stepping stone to utilizing this commercially available equipment on our other mines, reducing our overall methane emissions and potentially creating carbon offset credits," Winberg added.

    As a result of the emergence of trading markets for GHG emission reductions, voluntary initiatives like the McElroy VAM project can generate revenue from the sale of carbon offset credits. The value of these credits enables mine operators such as CONSOL to secure capital from companies like Verdeo to pay for the RTO technology. The carbon offset credits generated from the VAM oxidation project at the McElroy Mine will be registered with the Climate Action Reserve, a leading pre-compliance certification program in the U.S. that approved a protocol for coal mine methane projects in 2009.

    Development efforts between CONSOL and Verdeo are actively underway. The project is expected to become operational in the second quarter of 2011.
