Reducing Natural Gas Pipeline Emissions 83%

The ECOreport looks at the role a Google Street View mapping car had reducing New Jersey’s natural gas pipeline emissions 83%

screen-shot-2014-03-18-at-3-43-47-pm1Some of PSE&G’s (PSE&G) natural gas  pipelines were laid down a century ago. The New Jersey utility continued using cast iron until the 1950s. Now there is approximately one methane leak for each of the pipeline’s 3,900 miles. Though PSE&G intends to replace the entire cast iron and unprotected steel infrastructure, this is too costly ($1.5 million to $2.0 million per mile)to do overnight. With the help of new technology developed by Environmental Defense Fund (EDF), Google and Colorado State University. PSE&G is natural gas pipeline emissions by 83% in the area surveyed area, while replacing about 1/3 less mileage to do so.

Christy Clark’s LNG Conference Shadowed By BC’s Opposition

There were two LNG conferences this week. BC’s Premier, Christy Clark, brought several of her key ministers to a three day event at Vancouver’s Convention Centre May 21-23. Sixteen First nation’s companies were among the 200 exhibitors. There were 1,400 delegates from the World’s top LNG producers. Shell, Chevron and Malaysia’s state owned Petronas were all present. This was a sold out business event. Christy Clark’s LNG Conference was shadowed by BC’s opposition, some of whom held their own conference at SFU’s Harbour Centre.

US GHG Emissions Dropping

By Roy L Hales

Screen-shot-2014-03-18-at-3.43.47-PMThe U.S. Environmental Protection Agency (EPA) has just released its  2012-2013 emissions report and shows decreases in every sector. There has been a 10% drop below 2005 levels, which the EPA is largely crediting to the increased usage of natural gas.

Francis O’Sullivan on the climate impact of ‘leaky methane

Researchers find that national estimates of methane emissions have been underestimated over the past 20 years.

Natural gas has been touted as a “bridge fuel” to a less carbon-intensive future, as it generates far less carbon dioxide than energy produced by burning coal. But the natural gas production, processing, and distribution system leaks methane, another powerful greenhouse gas. A study published today in the journal Science reports that federal estimates of methane emissions have consistently underestimated the methane leaking from the natural gas system over the last 20 years. The study’s new estimates raise questions about natural gas’s actual climate benefit.
