Between 2009 and 2014, enough natural gas was lost through venting, flaring and leaks to power more than five million homes for a year. States, Tribes and federal taxpayers also lose royalty revenues when natural gas is wasted. According to a 2010 Government Accountability Office report, taxpayers lose up to $23 million annually in royalty revenue. Continue reading “Feds eye new methane rules for public lands”→
FRISCO — Reducing methane leakage from drilling sites, pipelines and storage tanks represents a huge low-cost opportunity in the battle to cut greenhouse gas emissions, according to a new report that says 3.5 trillion cubic feet of gas — worth about $30 billion — escaped from oil and gas sector operations in 2012.
In some gas fields, leak rates appear close to official estimates
FRISCO — Boulder-based researchers have used thousands of detailed measurements taken during overflights to take a nuanced look at methane leaks from natural gas fields.
The findings show methane leaking at the rate of tens of thousands of pounds per hour in three major natural gas basins that span Texas, Louisiana, Arkansas and Pennsylvania. But the overall leak rate from those basins is only about one percent of gas production there — lower than leak rates measured in other gas fields, and in line with federal estimates.

Researchers say energy companies have little incentive to prevent leaks
FRISCO — A team of engineers and scientists say that up to 15 billion cubic feet of natural gas, worth some $90 million, may be escaping from leaky pipes in the Boston area.
The researchers, led by atmospheric scientists at Harvard School of Engineering and Applied Sciences calculated the figure by analyzing a year’s worth of continuous methane measurements, using a high-resolution regional atmospheric transport model to calculate the amount of emissions.
Increase in global gas production likely to displace renewable low carbon energy
FRISCO — Increasing production of natural gas won’t save the world from global warming, researchers said this week.
In the long run, a global abundance of inexpensive natural gas is likely to displace not just coal, but also lower-emitting nuclear and renewable energy technologies such as wind and solar. Inexpensive natural gas would also accelerate economic growth and expand overall energy use, the study found.
“The effect is that abundant natural gas alone will do little to slow climate change,” said lead author Haewon McJeon, an economist at the Department of Energy’s Pacific Northwest National Laboratory. “Global deployment of advanced natural gas production technology could double or triple the global natural gas production by 2050, but greenhouse gas emissions will continue to grow in the absence of climate policies that promote lower carbon energy sources.” Continue reading “Study: Natural gas boom won’t slow global warming”→
FRISCO — As frackers desperately try to pump every last bit of gas from the ground before the global warming clock runs out, scientists warn that methane emissions could push Earth over a climate tipping point in just a few years.
