Into The Coal Bed Methane Market
Capstone microturbine to power plant that reduces methane gas and generates clean power
Capstone Turbine Corp., a manufacturer of microturbine energy systems, said it has added the U.S. coal bed methane market to its portfolio of oil and gas applications with the installation of the country's first methane-fueled C200 at a Consol Energy Inc. gas processing plant in Fallowfield, Pennsylvania, U.S.A.
Diversified-fuel producer Consol estimates the 200kW microturbine will eliminate 5884 tonnes/yr of coal bed methane-produced carbon dioxide from the atmosphere. The company said the anticipated annual energy cost savings is US$80 000.
Capstone said its C200 microturbine produces low-emissions power that the plant uses to recover 524 456 m3/yr of methane gas and generate 1.3 million kWh of clean electrical power. Unlike traditional generation technologies, microturbines are well suited to using gas with low methane content. The Fallowfield microturbine continuously operates with methane concentrations around 33%, said the company.
A 2011 U.S. Department of Energy report stated, "Coal bed methane proved reserves and production have grown nearly every year since 1989. Today, it accounts for more than 8% of total domestic natural gas production and nearly 8% of U.S. proved reserves. The U.S. Energy Information Administration (EIA) believes coal bed methane will continue to hold a similarly important share in the domestic energy picture between now and 2035."
