EVs Powered by Electricity from Natural Gas, Wind, Water, or Solar Power May Reduce Environmental Health Impacts
January 12, 2015 — A new study published in the Proceedings of the National Academy of Sciences and edited by JISEA's Doug Arent assesses 10 alternatives to conventional gasoline vehicles and the life cycle air quality impact of each on human health. The study finds that electric vehicles (EVs) powered by electricity from natural gas or wind, water, or solar power are best for improving air quality. Vehicles powered by corn ethanol and EVs powered by coal appear to increase environmental health impacts relative to conventional gasoline. Arent edited the article, "Life cycle air quality impacts of conventional and alternative light-duty transportation in the United States," as an invited guest editor of the journal's Editorial Board.

GHG from Electricity Produced from Shale Gas on Par with Conventional Natural Gas, Lower than Coal on Average
Study Published in Proceedings of National Academy of Sciences
July 21, 2014 — A new study published in the Proceedings of the National Academy of Sciences says estimates of life cycle greenhouse gas (GHG) emissions from electricity generated from shale gas are similar to those from conventionally-produced natural gas, and both energy sources, on average, emit approximately half the GHG emissions of coal-powered electricity. However, under certain circumstances, the emissions for conventional and shale gas electricity can reach levels approaching best-performing coal-fired plants.
Published on July 21, "Harmonization of Initial Estimates of Shale Gas Life Cycle Greenhouse Gas Emissions for Electric Power Generation," uses a meta-analytical technique called harmonization to compare existing studies estimating life cycle GHG emissions from shale gas, conventionally-produced natural gas, and coal.
"Published studies and articles about greenhouse gas emissions have come to widely differing conclusions; harmonization helps to clarify the existing knowledge on this important topic," National Renewable Energy Laboratory Senior Scientist and lead author Garvin Heath said. "With a more 'apples-to-apples' comparison provided by harmonization, a clear tendency emerges in the published literature. We see that life cycle GHG emissions from electricity generated from shale gas are similar to those from conventionally-produced natural gas. Both energy sources, on average, emit approximately half the GHG emissions of coal-powered electricity when considering emissions from the smoke stack and those upstream through the supply chain. Further, through development of novel probability distribution functions, we find assumptions about lifetime production of wells and the practice of liquids unloading to have the greatest influence on the results."
Study authors—Heath and Patrick O'Donoughue of NREL and Douglas Arent and Morgan Bazilian of the Joint Institute for Strategic Energy Analysis—emphasized the importance of actual measurements of GHG emissions to advance understanding of energy options.
"Harmonization of prior estimates of GHG emissions provides greater precision, but does not fully address the questions of accuracy of our knowledge of GHG emission sources in the natural gas supply chain, questions we highlighted in our recent article in Science magazine synthesizing 20-plus years of research on methane leakage from natural gas systems," Arent said. "As called for in that article and this one, verified measurements of emissions from components and activities throughout the natural gas supply chain, and robust analysis of lifetime well production and the prevalence of practices to reduce emissions, can help create a more robust understanding of our energy options."
The study team screened hundreds of published life cycle assessments for quality and modern relevance, including dozens related to conventionally produced natural gas and shale gas. In addition, the team conducted sensitivity analysis on three important activities in the production of shale gas—well completion, well recompletion, and liquids unloading. Previous research had found these activities to be significant to life cycle GHG emissions. When considering these additional factors, shale gas life cycle GHG emissions could approach the range of best-performing coal-fired generation.

White House Enlists JISEA to Help Bolster Co-Investment in Renewable Energy and Natural Gas
April 2014 — The White House honored solar energy deployment Champions of Change from across the United States during a full-day event April 17. The event featured panels discussing the successes of community leaders, innovators, educators, and organizers in creating opportunity for solar power and in driving policy changes at the local level to advance solar deployment in the United States. Arent moderated a panel focused on how solar, along with other renewable energy technologies, can work synergistically with natural gas to advance our nation's energy portfolio, and facilitate the path toward a clean energy future. During the panel it was announced that JISEA would host a series of workshops focused on the unique opportunities for greater synergistic use of natural gas and renewable energy. The workshops—part of a larger White House initiative supporting solar deployment and jobs—will be held in four locations: New York, Washington DC, Texas, and California.

Arent a Lead Author on IPCC Report on Climate Change Impacts, Adaptation, and Vulnerability
March 2014 — The Intergovernmental Panel on Climate Change (IPCC) issued a report today that says the effects of climate change are already occurring on all continents and across the oceans. The world, in many cases, is ill-prepared for risks from a changing climate. The report also concludes that there are opportunities to respond to such risks, though the risks will be difficult to manage with high levels of warming.
The report, Climate Change 2014: Impacts, Adaptation, and Vulnerability, from Working Group II of the IPCC, details the impacts of climate change to date, the future risks from a changing climate, and the opportunities for effective action to reduce risks.
JISEA's Doug Arent was coordinating lead author of chapter 10 of the report. A total of 309 coordinating lead authors, lead authors, and review editors, drawn from 70 countries, were selected to produce the report. The authors and editors were selected in 2010 from a pool of more than 1,200 nominations.
The report concludes that responding to climate change involves making choices about risks in a changing world. The nature of the risks of climate change is increasingly clear, though climate change will also continue to produce surprises. The report identifies vulnerable people, industries, and ecosystems around the world. It finds that risk from a changing climate comes from vulnerability (lack of preparedness) and exposure (people or assets in harm's way) overlapping with hazards (triggering climate events or trends). Each of these three components can be a target for smart actions to decrease risk.
New Article Discusses Cyber Security and Critical Energy Infrastructure
March 2014 — A new article published in The Electricity Journal examines the implications of increased cyber attacks on companies providing critical energy infrastructure. As power networks and, to a certain extent, oil and gas infrastructure, are becoming increasingly integrated with information communication technology systems, they are growing more susceptible to cyber attacks.
Study on Methane Emissions from Natural Gas Systems Indicates New Priorities
Study findings published in Policy Forum of Journal Science
February 2014 — A new study published in the journal Science says that the total impact of switching to natural gas depends heavily on leakage of methane (CH4) during the natural gas life cycle, and suggests that more can be done to reduce methane emissions and to improve measurement tools which help inform policy choices.
Published in the February 14 issue of Science, the study, "Methane Leaks from North American Natural Gas Systems," presents a first effort to systematically compare North American emissions estimates at scales ranging from device-level to continental atmospheric studies. Because natural gas emits less carbon dioxide during combustion than other fossil fuels, it has been looked to as a 'bridge' fuel to a lower carbon energy system.
"With this study and our larger body of work focusing on natural gas and our transforming energy economy, we offer policymakers and investors a solid analytical foundation for decision making," said Doug Arent, executive director of the Joint Institute for Strategic Energy Analysis (JISEA) and a co-author to the study. "While we found that official inventories tend to under-estimate total methane leakage, leakage rates are unlikely to be high enough to undermine the climate benefits of gas versus coal."
The article was organized by Novim with funding from the Cynthia and George Mitchell Foundation and led by Stanford University's Adam Brandt. It was co-written by researchers from Stanford University, JISEA, Energy Department's National Renewable Energy Laboratory (NREL), University of Michigan, Massachusetts Institute of Technology, National Oceanic and Atmospheric Administration, University of Calgary, U.S. State Department, Harvard University, Lawrence Berkeley National Laboratory, University of California Santa Barbara, and the Environmental Defense Fund.
"Recent life cycle assessments generally agree that replacing coal with natural gas has climate benefits," said Garvin Heath, a senior scientist at the NREL and a lead author of the report. "Our findings show that natural gas can be a bridge to a sustainable energy future, but that bridge must be traversed carefully. Current evidence suggests leakages may be larger than official estimates, so diligence will be required to ensure that leakage rates are actually low enough to achieve sustainability goals."
Among other key findings of the research:
- Official inventories of methane leakage consistently underestimate actual leakage.
- Evidence at multiple scales suggests that the natural gas and oil sectors are important contributors.
- Independent experiments suggest that a small number of "super-emitters" could be responsible for a large fraction of leakage.
- Recent regional atmospheric studies with very high emissions rates are unlikely to be representative of typical natural gas system leakage rates.
- Hydraulic fracturing is not likely to be a substantial emissions source, relative to current national totals.
- Abandoned oil and gas wells appear to be a significant source of current emissions.
- Emissions inventories can be improved in ways that make them a more essential tool for policymaking.
