Calgren Dairy Fuels dairy digester pipeline cluster–California’s first–captures methane from cow manure to reduce greenhouse gas emissions and provide a carbon-negative fuel  Southern California Gas Co. (SoCalGas) and biogas producer Calgren Dairy Fuels (Calgren) today announced that renewable natural gas produced at Calgren’s dairy digester facility in Pixley, California is being injected into SoCalGas pipelines. The project marks the first time that carbon-negative renewable …

 AMERICA’S NATURAL GAS SYSTEM IS LEAKY AND IN NEED OF A FIX   The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, as well as those from the natural gas industry specifically. Natural gas consists predominantly of methane. Even small leaks from the natural gas system are …

Researchers Note Gas Emissions From Marcellus Shale and Other Sites Linked to Significant Increased Risk of Near-Term Climate Change Far from being a “solution” to climate change, natural gas extracted from shale is a huge contributor of greenhouse gases when both methane and carbon dioxide are considered, according to a major new study by three Cornell University researchers. The natural …

New study concludes that natural gas offers greenhouse gas advantages over coal despite higher EPA estimates of methane emissions from natural gas systems. Washington, D.C.-Over its full cycle of production, distribution, and use, natural gas emits just over half as many greenhouse gas emissions as coal does for equivalent energy output, according to a new study from the Worldwatch Institute …
