NASA helped locate over 300 methane hot spots across California

By Tim O'Connor / Published: October 2, 2017

Last week the California Air Resources Board (CARB) and California Energy Commission (CEC) released interim results from a NASA study that offers the most clear-eyed assessment yet of California’s largest individual sources of methane pollution.

Methane – a potent greenhouse gas responsible for about a quarter of global warming – is emitted from several different sources, including refineries, landfills, dairy farms, and oil and gas facilities. This new study identifies 329 of the largest pollution sources and offers insights to policy makers about opportunities for reducing these emissions.

Here are four key takeaways from the latest research.

California must focus on super emitters to cut pollution

Previous studies in other regions have shown that when it comes to methane, a small set of high-emitting sites, known as “super emitters” tend to be responsible for a significant amount of total emissions. The new CARB study suggests the same is likely occurring in California (measurements of actual amounts of the methane will be released in the second phase of the project next year).  Many times these super emitters occur randomly, such as when a major piece of equipment breaks and releases a large amount of pollution. Other times, as this study shows, these sites can be landfills, dairy farms, and refineries that simply release a lot of pollution.  Read More »

In tackling methane, Exxon signals commitment to maximize opportunity for New Mexico

By Jon Goldstein / Published: October 2, 2017

An announcement last week from one of the country’s largest natural gas producers may have a major positive impact on revenue and clean air in New Mexico. XTO Energy, a subsidiary of ExxonMobil that made a $6 billion investment in acreage in New Mexico’s Permian Basin earlier this year, has now announced a set of commitments to “continually reduce methane emissions” from its production and midstream operations nationwide.

In making the announcement, XTO CEO Sara Ortwein made special note of the methane actions’ impact in the Permian, stating, “In particular, we’re looking forward to applying this approach to our planned expansion in the Permian Basin in New Mexico and West Texas.”

The XTO methane mitigation commitment includes a plan to find and fix methane leaks through inspections using technologies at both existing and new facilities. Further, building on a successful technology pilot project in the nearby Midland Basin, XTO will also focus on emission prevention, moving toward the use of new, less polluting devices for tank batteries and other facilities.

This trade dispute could upend America’s booming solar industry. Here’s what it means for you.

By Lenae Shirley / Published: September 29, 2017

If you work in the solar industry, want to buy solar panels or care about climate change, you may want to pay attention.

Two floundering solar manufacturers, with no concerns but their corporate bottom line, are about to pull the rug from under one of America’s fastest-growing industries and tens of thousands of well-paid jobs.

The manufacturers petitioned the U.S International Trade Commission this spring to take action against foreign competitors, claiming overseas rivals export products to America’s solar market at prices they can’t match. This at a time when the United States solar industry as a whole is booming.

In a decision that shook the industry and a host of free-trade advocates, ITC agreed with these single two petitioners and it’s now up to President Trump to decide whether to retaliate with an import tariff or other punitive options.

There’s a good chance he will – and this would be really bad news for American solar companies and consumers alike. Read More »

Experts weigh in: we need to learn about chemicals in oilfield wastewater before reusing it outside the oilfield

By Dan Mueller / Published: September 29, 2017

Oil and gas companies are looking for new ways to reuse salty, toxic wastewater — including crop irrigation.

A recent publication of the Air and Waste Management Association (AMWA) contained a number of articles by academia and industry experts about the many challenges of managing the nearly 900 billion gallons of wastewater (also called produced water) generated every year by oil and gas production. This wastewater is not only very salty but also contains a number of chemicals (many toxic) and potentially radioactive material.

The majority of this wastewater is disposed in deep underground wells to minimize the risks of it coming into contact with humans or the environment (though leaks and spills at the surface are still a big concern). But in hope of lowering costs, in recent years industry has been trending toward finding other ways to either dispose of or recycle this waste – in part because demand for water resources is increasing in drought prone areas and because disposal wells have been linked to a rise in earthquakes.

The articles in AWMA’s magazine suggest that recycling oilfield wastewater to complete new wells is the most viable alternative to traditional disposal methods. Definitely more viable than reusing this water in other ways outside oil and gas operations. Read More »

Massive Pennsylvania gas leak proves industry requires more oversight

By Andrew Williams / Published: September 28, 2017

Yet again, another energy company is serving up tangible proof that some in the industry fail to take steps to operate responsibly and protect public health from oil and gas pollution.

According to a September 24 Associated Press article, a malfunction at a natural gas compressor station in Northeastern Pennsylvania resulted in a massive gas leak that — in just a few hours — produced more air pollution than most facilities emit in an entire year.

Most Pennsylvanians never know about these types of malfunctions. In fact, if it were not for the AP story, you might not have heard about this leak in part because DTE Energy – the out-of-state energy company that owns the facility – failed to immediately notify the Susquehanna County Emergency Management Agency. Instead, they waited over a week to report the problem to the county and downplayed the magnitude of the episode, referring to it as a merely a “minor” leak. Read More »

The power of energy data in Illinois and beyond

By Dick Munson / Published: September 27, 2017

The U.S. electricity industry is experiencing unprecedented innovation and change. The grid is getting smarter and customers can play a more active role in how their electricity is made, moved, and used. Between all the initiatives that utilities, cities, and states are pursuing and the new services and products that entrepreneurs are creating, it can be difficult to keep up.

That’s why I enjoy connecting with and learning from colleagues at events like the Demand Response and Distributed Energy Resources World Forum. Held in Costa Mesa, California on Oct. 10-11 this year, the forum brings together stakeholders from across the clean energy industry to discuss the latest technology and business strategies for increasing distributed energy resources – like solar panels and batteries – and demand-side resources like demand response.
