Do Shale Gas Activities Play A Role In Rising Ozone Levels?

As we continue seeking relief from rising temperatures this month, it’s also time to be on the watch for ozone alerts. The annual Texas smog season – April 1 through October – already appears to be in full swing this year with numerous counties around the state exceeding health-based ozone concentrations many times since March.

Just last week, the Houston Chronicle highlighted the magnitude of ozone exceedances that the area hasn’t seen since 2003. Additionally, the month of May was the nation’s “smoggiest” in the past five years according to a recent report released by Clean Air Watch. Texas ranked second, surpassed only by California, for the most Code Red and Code Orange days so far in 2012, with 18 days and 27 days respectively.

Ozone-forming pollution is emitted by cars, refineries and various industrial plants. As more Texans begin to see shale gas drilling rigs pop up around them, many are asking the question: Could emissions from natural gas and oil operations significantly contribute to ground-level ozone? The answer is an unequivocal yes.

The Role of Natural Gas and Oil in Rising Ozone Levels

While burning natural gas produces less smog-forming pollution than coal combustion but more than renewable energy generation, much of the equipment used in the drilling, production, processing and transporting of natural gas and oil produces significant amounts of such pollution. This equipment releases volatile organic compounds (VOCs) and oxides of nitrogen (NOx), which combine in the presence of sunlight to form ground-level ozone or “smog.” According to the state of Colorado, natural gas and oil operations were the largest source of ozone-forming pollution, VOCs and NOx in 2008.

The Texas Commission on Environmental Quality has reported that storage tanks used in the exploration and production of natural gas and oil are the largest source of VOCs in the Barnett Shale. Recently, there have been additional concerns that San Antonio may not meet federal ozone standards due to Eagle Ford Shale development. Peter Bella, natural resources director at the Alamo Area Council of Governments, told the Houston Chronicle that the city is “right on the edge of nonattainment.”

Ozone concentrations comparable to those recorded in some of the most heavily polluted U.S. cities have been measured in rural parts of Wyoming and Utah, where little other industrial activity occurs:

It’s important to note, however, that ozone monitoring does not exist in many oil and gas development areas, so we don’t know the full extent of the potential problem. For instance, though the Texas Commission on Environmental Quality has committed to start monitoring in the Eagle Ford, there is not currently sufficient monitoring to characterize ozone problems in the area.

Protection of Human Health

As natural gas and oil development expands into new regions, adverse air impacts are likely to follow, absent sufficient emissions controls. It is crucial for states to have strong standards in place, especially for a state such as Texas, which experienced exponential production increases in a short period time. The Eagle Ford Shale alone saw a 432 percent increase in natural gas production from 2010 to 2011.

We are happy to report that EPA recently finalized clean air measures that will serve as an important first step in reducing harmful pollution discharged from a variety of oil and natural gas activities. In fact, last month, EDF President Fred Krupp testified before the U.S. Senate in support of these new clean air standards, which will result in significant reductions in smog-forming pollutants and hazardous air pollutants like benzene, a known carcinogen. As a co-benefit, the standards will also reduce methane, a potent climate forcer.

In his testimony, he said “these common sense measures are a win-win: they reduce pollution, conserve valuable domestic energy resources, and in some cases, actually save producers money.” He added that it was “critical that we build on these clean air measures if our nation is to fulfill the President’s promise in his State of the Union to develop natural gas without putting the health and safety of our citizens at risk.”

While mounting evidence continues to link natural gas drilling with rising ozone levels, it is important to remember why we should care in the first place:

  • Ozone has been linked to a host of maladies, including premature mortality, heart failure, increased hospital admissions and emergency room visits for respiratory causes among children and adults with pre-existing respiratory disease, such as asthma and inflammation of the lung, and possible long-term damage to the lungs.
  • Children, the elderly, and people with existing respiratory conditions are the most at risk from ozone pollution.
  • Ozone also damages crops and ecosystems. Ozone is one of the most phytotoxic air pollutants – causing damage to vegetation in national parks and wilderness areas, especially in mountain regions and to valuable crops.
  • Ozone pollution also contributes to climate change. According to the Intergovernmental Panel on Climate Change (IPCC), ozone is the third-largest contributor to climate change after carbon dioxide and methane.

In the end, we’re talking about the protection of human health as well as our entire planet. Continue to visit this blog for updates on rising ozone levels in our state, as well as other vital information related to Texas air quality.

Postcard From Mark Brownstein In Israel- The Negev Desert

High tech entrepreneurs here repeatedly tell you that Israel is a small market, so if you hope to have your idea become a commercial success, from the start it must be designed and developed with other countries and cultures in mind.  What is true for software is also true for innovative ideas for sustainable living.  The Jacob Blaustein Institute for Desert Research, a program of the Ben-Gurion University of the Negev was established in 1974 to facilitate the sustainable development of the Negev desert – an area comprising 60% of Israel’s total land mass – but quickly established itself as one of the world’s leading research institutions on the challenges of living sustainably on the world’s many dry lands.  Professor Pedro Berliner, the director of the Institute tells the story of how they discovered that planting acacia trees in close proximity to crops like wheat or maize produces better results for both trees and crop than if planted apart.  The idea was piloted in Kenya and is now being brought to Botswana, where the Blaustein Institute hopes to develop a permanent presence in partnership with one of Botswana’s existing universities.  This is a good reminder that simple, low-tech solutions can often make a big difference to both people and the planet.

Of course, when it comes to energy, things are rarely ever simple.  Professor David Faiman, Chair of the Department of Solar Energy & Environmental Physics at the Blaustein Institute, spent the rest of the morning explaining the challenges of bringing solar energy to scale.  For over 30 years, Dr. Faiman has pioneered research into concentrated solar, and a commercial product based on his research, manufactured and marketed by Zenith Solar, shows tremendous promise for raising efficiency, lowering cost, and greatly reducing the physical footprint of commercially meaningful quantities of solar electricity.  Dr. Faiman would surely be both embarrassed and amused to be called a solar energy rock star, but I’ll call him that all the same. 

Equally exciting is the work Dr. Faiman has been doing to conceptualize what would be required to transition Israel’s electric grid to renewable energy.  Dr. Faiman, like many Israelis I’ve met on this trip, is both a visionary and a realist.  On the one hand, he believes it is possible for Israel to get to 90 percent renewable energy based on solar, energy storage, and natural gas-fired generation, but on the other hand, he believes it could take 60 years to get there.  His primary point is that Israel needs to start the transition now for there to be any hope of making even a 60 year deadline.  This means phasing out coal (which Israel continues to depend on quite a bit) and staying away from nuclear, both of which are too inflexible for a renewable-centric world.  Investments in natural-gas fired generation might be ok, as some of these facilities would likely be required to recharge the energy storage systems that would perform the lion’s share of the work in-filling where solar output is unavailable or varies.  His overarching concern is that Israel will continue to make short-term decisions that lead to the construction of conventional energy infrastructure, such as new coal plants (a proposal for a new plant was only narrowly defeated two years ago)  that all but lock the nation into a long-term future of fossil fuel dependence and high carbon pollution.

After a short visit to the research facility of Brightsource, a concentrating solar energy provider active in the United States, we began our hour and a half journey back to Tel Aviv.  As the bus rumbled along, I reflected on the irony that in a land of all this energy technology innovation, so little of it is actually deployed in Israel.  Indeed, practically the only place you see solar photovoltaic panels deployed in Israel are on the ramshackle homes of the Bedouin, who for a variety of reasons, are not otherwise connected to Israel’s electric grid.  Tel Aviv may be a sophisticated, high tech capital, but it is the agrarian, socially-traditional Bedouin, who is light years ahead when it comes to embracing advanced energy technology.

I’ve now asked several Israelis why this is, and two answers stick out in my mind.  The first is that Israel is a place where everyone focuses on the near term, because the future is so unpredictable.  Random rocket attacks (a rocket slammed into Beersheva this morning about a half hour after we checked out of our hotel there) and sudden outbreaks of serious fighting certainly contribute to a “live for this moment” attitude.   The second answer is tied to the first.  As one Israeli explained to me, after the Yom Kippur War in 1973, Israel, like the rest of the world suffered the consequences of high oil prices and invested in renewable energy, but as oil prices fell, the government came to view renewable deployment as expensive and unnecessary.   The recent experience of the oil embargo notwithstanding, the energy minister at the time concluded that Israel’s energy requirements will always be so small in the general scheme of things that even in times of global shortage there will always be fossil fuels available somewhere, albeit at a price.  In short, Israel did not have an energy supply problem, it had a money problem, and the only challenge was to find the cheapest of available options.

Fast forward to today.  The Egyptian natural gas pipeline that carried 40 percent of Israel’s natural gas supply was blown up this spring.  And, what is the response?  The Israel Electric Company simply switched to purchasing fuel oil and coal while it waits for the nation’s significant new offshore gas reserves to come on line.  A triumph for short term thinking in a nation that sells its visionary clean energy technologies to the rest of the world.

Postcard From Mark Brownstein In Sderot, Israel

(Credit: www.allnumis.com)

“Remember, when you hear the siren, you have 15 seconds to find cover.”  Such is life in the southern Israel town of Sderot only a few kilometers away from the Gaza Strip.  Fortunately, for my tour, today’s rocket attacks fell on the outskirts of town and did not affect our visit.  Israelis often point to such events as the reason why environmental issues are often not very high on the public policy agenda.  How hard is it to spend any time thinking about global warming, when there are more tangible and immediate threats confronting you?

And yet, global warming is having an immediate and tangible impact here as well.  Our visit to Sderot came after a tour of Israel’s largest desalination plant located in the neighboring town of Ashkelon on Israel’s Mediterranean coast.  Israel is chronically short of water, consuming 2 billion cubic meters of water per year where the nation’s natural hydrology is capable of producing, on average, 1.2 billion cubic meters per year, according to Abraham Tenne, head of the Desalination Division of the Israel Water Authority.  Mr. Tenne was blunt in reporting the facts.  The Israel Water Authority expects average rainfall to decline by 15 percent by 2040, while Israel’s population is expected to continue to grow by 1.7 percent each year.  The drought of 2008, where rainfall was only 65 percent of the current average, was a powerful reminder that today’s water situation is bad, and unchecked, it will only get worse. 

Mr. Tenne is understandably proud of the building or upgrades to Israel’s three desalination facilities, which are key to solving the problem, but he is quick to remind us that, as important as this technology is to Israel’s future, it is a last resort.  Israel’s consumption of 2 billion cubic meters of water by a population of roughly 8 million stands in sharp contrast to Arizona’s consumption of 8 billion cubic meters of water by a population of roughly 7 million.  He visited Arizona last year for an international water conference where he was asked to speak on desalination, and was shocked to see flood irrigation – the practice of watering crops by flooding the field – commonly practiced.  He contrasts this with Israel, where drip irrigation is standard practice for 95 percent of all agricultural production, and where the amount of water used is precisely controlled by technology that monitors the moisture at the root of the plant, delivering only what is required to maintain healthy growth.  He then tells us about London, which just inaugurated its first desalination plant, while doing little to fix the local water system where 40 percent of the water flowing through the system is lost to leaks.  And then, for the second time in two days, I hear of smart grid technology being deployed in Israel to pinpoint leaks.

Although recent discoveries of significant natural gas reserves off the Israeli coast suggest that Israel may be able to completely wean itself off coal, over 35 percent of the nation’s installed electric generation capacity comes from coal-fired power plants, including one right next door to the Ashkelon desalination plant we visited today.  But even when the desalination process is driven by natural gas-fired power plants, as this facility is (it generates its own electricity and actually sells some excess production back to the grid) the fact of the matter is that Israel’s total water system – not just desalination, but the pumps necessary to move water around the country – consumers 6 percent of the total electricity produced in Israel.  Thus, the battle to conserve water is also a battle to save energy, which in turn is a battle to avoid carbon emissions that contribute to global warming, and make Israel’s water situation worse.

We are spending tomorrow with some of Israel’s leading experts in solar energy, but already I am wondering why a nation so obviously blessed with ample, strong sunlight, seems to have so little invested in deploying solar power.  Solar hot water heaters have been required here since 1980, and as my friend, and EDF consultant, Roger Duncan, often reminds me, solar hot water heating is often the most overlooked cost-effective solar technology, but given Israel’s pressing challenge of finding both secure and sustainable supplies of electricity, the government’s policy of 10 percent renewable energy by 2020 seems incredibly modest.  A nation with the determination and technological prowess to erect the world’s most sophisticated missile defense system surely should be able to do better and tomorrow will be about finding out why not.

Energy Documentaries – Educational Or Sensational?

The 24-hour news cycle has prompted a higher quantity of topics brought to viewer’s and reader’s attention.  However, with sound bites and the brevity of social media, rarely are topics reported with a balanced level of quality.  Film documentaries are evolving as a more sophisticated medium to explore issues in expanded formats with interviews, commentary and a wider perspective.  But are some of these documentaries more fiction than fact?

An Inconvenient Truth advocated common sense about climate issues.  The Academy-Award nominated Gasland sparked much controversy about exploration and production of natural gas.  Its sequel, Gasland II, is scheduled to air on HBO this summer.  This week, a film Truthland debuted on YouTube (not in theaters) with more splash than substance.

Of EDF’s core strategies of sound science, market-based solutions, non-partisan policy and unlikely partnerships – a most unlikely partnership was mischaracterized by the producers of Truthland.  My words in an interview in the documentary are accurate, but the context in which they were presented — implying that EDF agrees with the rhetoric presented in the film — is misleading.  When interviewing for this film over a year ago, I was not told that the film would be subsequently sold to Independent Petroleum Association of America (IPAA) and Energy In Depth (EID), and used a promotional tool for the natural gas industry.  In hindsight, I should have demanded more limitations on my interview – but the producers were very convincing when pitching the film as a presenting a “balanced perspective” on the natural gas debate.

Rather than promoting Truthland, I suggest a more impartial documentary choice where EDF’s Senior Energy Policy Advisor Scott Anderson is interviewed as demonstration of how EDF’s efforts can decrease the adverse effects of natural gas development.  The SWITCH Energy Project offers a more sound approach to reviewing the past, present and future of energy solutions for the U.S. and globally.  University of Texas’ Bureau of Economic Geology’s Director Dr. Scott Tinker explores the world’s leading energy sites, from coal to solar, oil to biofuels, with interviews of international leaders of government, industry and academia experts, plus a voice  in the environmental community.

Scott Anderson’s interview in the film describes the natural gas drilling method of hydraulic fracturing and the regulatory atmosphere of improving environmental aspects pertaining to water, land and air quality issues.

Postcard From Mark Brownstein In Tel Aviv, Israel

Source: Trekkie Gal

A lumber yard in the middle of Tel Aviv is an unlikely place to discover innovative new technology to transform ocean waves into energy, but there I was watching a demonstration of wave-to-energy technology in a makeshift wave tank constructed by Shmuel Ovadia.  Ovadia is a talented engineer passionate about harnessing the power of the ocean when he is not otherwise engaged in running his successful high-end lumber business.  See for yourself at:  http://www.sde.co.il/.

I suppose I shouldn’t have been surprised.  I am on the first day of a seven trip for U.S. energy leaders sponsored by Project Interchange, an educational institute of the American Jewish Committee, and by the time I arrived at Ovadia’s lumber yard in the late afternoon, I had already seen tremendous creativity in the unlikeliest places.  Our morning was spent walking down Tel Aviv’s Rothschild Boulevard, Israel’s equivalent of Silicon Valley, dropping by several of the technology incubators that are a large part of the reason why Israel is known as the “start-up nation.”  

Here, 20-somethings only a few years out of Israel’s army – where technology and project management skills are acquired and honed – are developing innovative software at a furious pace.  The aging, somewhat decrepit buildings dating back to Israel’s socialist early years, are brimming with entrepreneurial drive and youthful spirit.  Most interesting to me was a visit to the IDC Elevator, where Shmuel Chafets, Director of Business Development for Giza Venture Capital, described a recent investment in a start-up that is applying sophisticated software and smart grid technology to improve the efficiency of water delivery systems, which – among other things – anticipates leaks before they happen. 

In Israel, a nation increasingly reliant on energy-intensive desalination, saving water is also saving energy, a lesson at the heart of our report two years ago on the Energy-Water Nexus in Texas.  This visit got me wondering whether this same technology might be helpful in EDF’s efforts to partner with gas utilities to reduce methane leaks along their distribution systems.  Surely such smart grid ingenuity can be used to help fight the causes of global warming and not just the fresh water scarcity that is one of its many symptoms?

While software companies in Israel do well in attracting venture capital from the United States, Europe and, more recently, Southeast Asia, guys like Shmuel Ovadia struggle to attract capital to their bright ideas.  Even venture capitalists like to see commercial scale prototypes before investing major dollars, and good-old fashioned mechanical technologies are a whole lot more physically difficult and expensive to get to commercial scale than software solutions.  So it takes a special type of investor to risk the serious capital it takes to bring a hardware solution to market. 

It is a challenge, but not impossible, as our visit to Better Place’s Tel Aviv showroom demonstrated.  Here, we were treated to a test drive of the Renault Fluence ZE, an all-electric four passenger sedan, that has a range of approximately 100 miles and a battery that can either be recharged at home or our work or swapped out in a 5-minute visit to a Better Place ‘refueling’ station.  When you buy the car (and had we been Israelis, sales people were there ready to take our order), you buy a contract for miles to go with it.  Included in that contract are up to two charging stations, the electricity they supply, and access to any of Better Place’s battery swapping stations now being constructed throughout Israel. 

In short, the Better Place’s Renault Fluence is like the cell phone I have carried with me to Israel.  It is my phone, but I purchase the international sym card and the corresponding minutes of voice and data from Orange, a local carrier, which is easily slipped into the phone and recharged with new minutes as needed. 

Tomorrow we head down south to the Negev to see what is brewing in the world of solar energy.  I can only imagine what surprises await us.  I’ll keep you posted.

Ohio Energy Bill Falls Short Of Governor’s Vision For Chemical Disclosure

Ohio Governor John Kasich showed real leadership earlier this month when he introduced energy bill with the most comprehensive rules in the country for chemical disclosure during oil and gas operations. The Governor’s bill would have required disclosure of not only the chemicals used in hydraulic fracturing – as a number of other states have done – but also the full range of chemicals used throughout the lifecycle of a well. Hydraulic fracturing gets all the attention, but the Governor and his team understand that dangerous chemicals are also used in drilling, producing, servicing and shutting down wells. The entire process should be transparent from beginning to end — “from spud to plug,” as it’s called.

This was smart policy when the Governor proposed it. And it’s smart policy today. Unfortunately, the energy bill passed yesterday by the Ohio General Assembly fails to fully deliver on that vision. In the face of intense industry opposition, lawmakers eliminated many of the reporting requirements contained in the original bill. EDF is disappointed the final bill does not live up to what Governor Kasich proposed, but we give the Governor credit for putting the idea forward and expanding the terms of the debate – both in Ohio and nationally.

To be fair, even in its scaled-back version, the Ohio disclosure policy breaks new ground. It requires disclosure of the chemicals used in stimulating a well. This includes not just hydraulic fracturing but also other kinds of stimulation techniques – something most states have missed in their disclosure rules.

Additionally, companies will be required to disclose the chemicals used in a well until the surface casing is set in place. As we testified in the Ohio House, this still leaves the public in the dark about a lot of dangerous chemicals that are used to drill and operate a well. But again, it’s a step forward compared to what other states have done.

We’re disappointed, though, by changes the House made to the trade secret provisions in the bill. In the original version, companies would have been required to report trade secret information to the Department of Natural Resources. This would have ensured that the agency had quick access to chemical information it might need to respond to a spill, initiate an investigation or respond to a complaint.  Under industry pressure, the Assembly caved on that language, and companies will now be allowed to withhold trade secret information from the regulators. 

The bill establishes an unqualified right for certain land owners to challenge trade secret claims in court. So, there’s at least a mechanism in place to police the system and make sure companies aren’t hiding behind bogus trade secret claims. But it would have been far better to have trade secrets turned over to the state – not only in cases where this information is needed to protect public health and safety, but also because it would have given anyone, not just the land owners, a right to challenge trade secrets under the Ohio Public Records Act.

This is a big bill. It addresses a wide range of issues – not just oil and gas – and includes far too much to cover here. It has some good provisions, such as new requirements for companies to report where they’re getting their water from and how much they’re using, and requirements for companies to test the baseline water quality in nearby water wells before they start drilling. The bill also has some really bad provisions – like an egregious one that strips citizens of the right to appeal permits issued to oil and gas operators.

The passage of the energy bill is not the end of the process: the agency rules implementing this bill will be written in the months ahead, and EDF will be working to make sure they are as strong as possible. And we’ll be working on other rules to reduce the risks oil and gas operations pose to communities and the environment.

This includes improving Ohio’s rules for air pollution from oil and gas operations. It means making sure we have tough standards in place to manage the huge waste streams these operations produce. It means putting smart planning in place to preserve landscapes and protect the fabric of local communities. And sooner rather than later, it’s going to mean coming back to the General Assembly and fixing what didn’t get done right the first time.
