Shell becomes latest oil and gas company to test smart methane sensors

This week, the oil and gas giant Shell took a positive step toward addressing methane emissions. The company announced a new technology trial at a wellsite in Alberta, Canada, where it is piloting a specially designed laser to continuously monitor emissions of methane, a powerful pollutant known to leak from oil and gas equipment.

The move by Shell is a glimpse into the future and demonstrates growing market interest in smart, sensor-based methane detection technology. Shell’s project joins a similar field test already underway in Texas, operated by the Norwegian producer Statoil, and a California utility pilot run by Pacific Gas and Electric Company.

Each of these deployments is promising, but the ultimate test will be broad-scale adoption of innovations that generate actual methane reductions. Read More »

Time to Tell the EPA What Works in Methane Mitigation

methane_technicianThe Environmental Protection Agency (EPA) has committed to regulate existing sources of methane from the oil and gas industry, and it is asking for information from the methane mitigation industry to make sure the rule’s approach and requirements account for recent innovation. The EPA’s announcement comprises the U.S. portion of the North American commitment to cut methane by up to 45% from the continent’s oil and gas industry by 2025. Existing sources in the oil and gas industry make up over 90% of the sector’s emissions, which contribute over 9 million tons of methane pollution annually.

The opportunity is open now to tell the EPA what works in methane mitigation.

Emission standards for existing sources of methane will not only reduce greenhouse gases but could also create new markets and customers for the growing mitigation industry. The regulation will likely start with one or more approved work practices to find and fix methane leaks, describing a technology or group of technologies that must be used in a certain manner. For example, EPA’s New Source Performance Standards for new and modified sources of methane required the use of optical gas imaging cameras or “Method 21” instruments. With far more existing sources of methane than new or modified sources, being part of an approved work practice for existing sources would open up a significant market opportunity. Read More »

Regulation as a Platform for Innovation

To get anything accomplished, you can’t let the perfect be the enemy of the good. One unsung story buried in last week’s release of EPA’s new source methane rules may make good options even better – driving innovation and offering industry more options to meet the methane challenge.

The new rules target a pervasive problem: methane – the primary component of natural gas – leaking throughout the oil and gas value chain. Methane emissions represent a waste of saleable resources, a reputational risk, and a contributor to both poor local air quality and climate change.

Under the EPA’s framework, oil and gas operators must take steps to minimize  emissions from new and modified sources – from finding and fixing equipment leaks to swapping out equipment to reduce methane vented from pneumatic controllers and pumps,. Companies in Colorado working to comply with the state’s similar rule have reported that putting similar measures in place are cost-effective, even generating positive returns from selling the captured gas.

But what should an agency do when the solutions available now are reasonable but not perfect? Existing strategies don’t monitor all the time—only a few days a year. So leaks and malfunctions can be missed, or leak for months before they are fixed. Read More »

Coming Soon: Solutions for Finding Methane Leaks Faster

porter-ranch-aliso-canyon-methane-gas-leak-3-1020x610After more than four months of spewing potent methane pollution, the massive Aliso Canyon gas leak has finally been plugged. But now the state of California and the utility that owns the site, SoCalGas, are left with the responsibility of ensuring a disaster like this doesn’t happen again.

While Aliso Canyon has captured the attention of the nation, it’s important to remember that there are smaller—and far more prevalent—leaks happening throughout the country’s oil and gas supply chain every day. In fact, those emissions add up to more than 7 million metric tons of methane pollution every year.  That equals over $1 billion worth of wasted natural gas at 2015 prices. Read More »

How Fast is Fast Enough to Solve a Challenge Like Methane?

Methane Detectors Challenge testBill Gates, in an interview with The Atlantic, reminded us that if Thomas Edison were alive today, he’d probably recognize a lot of our energy infrastructure – batteries and most coal plants, for example. Gates argued in the interview that we need to drastically speed up the pace of innovation to bring our energy infrastructure out of the Victorian era. But how do we change how we make and use energy? It touches everything we do, but in less than a decade we will be living, working, and traveling differently.

That’s where I –and EDF – come in.  I joined EDF this fall after working as a lawyer, consultant and accelerator for business-social collaborations, and I’ve found that it takes all kinds of skills and experiences to set ambitious targets and turn the impossible into the inevitable. From energy retrofits for churches to starting a clean energy incubator with global energy companies, I’ve attacked the challenge of achieving a low-carbon future from many angles. I’ve been drawing on all of that experience since joining EDF, at what’s proving to be an exciting time for climate change leadership. Read More »
