Study analyzes innovations in lithium-​​ion bat­tery costs

College of Natural Resources - Mon, 07/31/2017 - 00:00

Stor­age prices are falling faster than solar PV or wind tech­nolo­gies, accord­ing to a new study by pub­lished in Nature Energy  by Energy & Resources Group graduate student Noah Kittner and professor Dan Kammen. The fall in prices is allow­ing new com­bi­na­tions of solar, wind, and energy stor­age to out­com­pete coal and nat­ural gas plants on cost alone.

The study found that R&D invest­ments for energy stor­age projects have been remark­ably effec­tive in bring­ing the cost per kWh of a lithium-​​ion bat­tery down from $10,000/kWh in the early 1990’s to a tra­jec­tory that could reach $100/​kWh next year. The pace of inno­va­tion is staggering.

Ordi­nar­ily, pub­lic research invest­ment and pri­vate ven­ture cap­i­tal money undergo tough scrutiny before money can be spent on research and the results from years of work are not imme­di­ately vis­i­ble. How­ever, this study shows that long-​​term R&D spend­ing played a crit­i­cal fac­tor in achiev­ing cost reduc­tions, and a recent lack of invest­ment for basic and applied research may miss the $100/​kWh tar­get for cost effec­tive renew­able energy projects. Mod­est future research invest­ment from pub­lic and pri­vate sec­tors could go a long way to unlock extremely low-​​cost, and low-​​carbon elec­tric­ity from solar, wind, and storage.

Miguel Altieri

Professor, Environmental Science, Policy, and Management 

Miguel Altieri is a leader in the field of agroecology—the application of ecological principles to provide solutions in agriculture. His work investigates ecological principles underlying traditional agriculture and applies these principles in modern agricultural systems to create more resilient and productive crops. His research on how to diversify cropping systems to enhance biological pest control has been implemented by many farmers worldwide. Altieri’s contributions to restoring the productive capacity of small farms with agroecology in Latin America helped to place agroecology on the radar of major scientific and international development institutions. From 2013-2017, he was president of the Latin American Scientific Society of Agroecology (SOCLA); he has also served as general coordinator of the United Nations Development Programme's Sustainable Agriculture Networking and Extension Programme and scientific advisor of FAO's Globally Ingenious Agricultural Heritage Systems (GIAHS). He has served as a visiting scholar at a number of universities around the world, is the recipient of two Fulbright Scholarships, and has been awarded multiple honorary doctorates. Altieri is the author of more than 250 journal articles and of more than 15 books, including Agroecology: the Science of Sustainable Agriculture (Westview Press, 1995). He will continue  supporting SOCLA and many other  academic and farmer organizations worldwide in the promotion and scaling up of  agroecology.

Robert Fischer Robert Fischer

Professor, Plant and Microbial Biology

Robert Fischer has been a faculty member at UC Berkeley since 1983. He studies the mechanisms that regulate gene imprinting in plants, which cause alleles to be expressed based on their parent of origin, research that is essential in understanding seed viability and plant reproduction. His research on DNA demethylation at the genome-wide level found that small euchromatic transposons, when demethylated, regulate the expression of adjacent genes, and that chromatin remodeling proteins are often required to make transposon targets accessible to DEMETER demethylation. Fischer was elected to the National Academy of Sciences in 2009. In 2010 he received the Distinguished Teaching Award from the College of Natural Resources, and he served as chair of the Department of Plant and Microbial Biology from 2011-2014. He plans to continue to teach biology classes at UC Berkeley as an emeritus faculty member.

Department of Bioengineering - Tue, 07/18/2017 - 17:17
Professor Sanjay Kumar’s lab collaborated to show how identical embryonic skin cells organize to produce follicles and feathers, based on resistance from the materials underlying the skin. This could lead to more practical use of stem cells to produce skin graft materials. The work was conducted with Amy Shyer, a Miller postdoctoral fellow, and visiting scholar Alan Rodrigues, of Professor Harland’s lab, and BioE PhD student Elena Kassianidou.

Stress worsens effects of toxic chemicals in pregnant women

College of Natural Resources - Mon, 07/17/2017 - 11:15
A closeup of the belly of a pregnant woman.

Data suggests that the harmful effects of smoking and air pollution are worse for pregnant women who also suffer from stress.

When a pregnant woman suffers from stress, she’s more likely to have a low-birth-weight baby than a non-stressed pregnant woman if both are exposed to the same toxic chemicals, according to the first study examining the combined impact of stress and environmental chemicals on fetal development.

Data suggests that the harmful effects of smoking and air pollution are worse for pregnant women who also suffer from stress.

The evidence is just emerging, but a team of researchers from UC Berkeley and UC San Francisco found that the impact of a pregnant woman’s exposure to several toxic chemicals commonly found in the environment was generally larger if the mom was stressed.

“It appears that stress may amplify the health effects of toxic chemical exposure, which means that for some people, toxic chemicals become more toxic,” said Tracey Woodruff, a professor in the Department of Obstetrics, Gynecology and Reproductive Sciences at the Philip R. Lee Institute for Health Policy Studies at UCSF. Woodruff, the senior author of the study, also directs UCSF’s Program on Reproductive Health and the Environment and the Environmental Health Initiative.

Taken individually, the adverse effects of stress or environmental chemical exposures on fetal growth are well known, yet their combined effect has not been clear. When combined, researchers found the strongest connection between smoking and low birth weight: highly stressed pregnant women who smoked were about twice as likely to have a low-birth-weight baby as less stressed smokers. Stress was quantified by factors such as socioeconomic status or years of education. The researchers did not investigate a potential mechanism for how stress and chemicals might interact to create this effect.

The study also showed that the effects of air pollution on low birth weight were heightened when combined with stress. Exposure to ambient fine particulate matter, a type of air pollution, increased the risk of African American women having a low-birth-weight baby compared to those who were white.

The research was published July 12 in the journal PLOS ONE, and was based on a systematic review of 17 human studies and 22 animal studies examining the links between chemicals, stress and fetal development.

While the research team saw evidence of stronger adverse developmental effects of prenatal chemical exposures in higher-stressed versus lower-stressed pregnant women, the specific results of these studies varied, making it difficult to define the precise magnitude of the effect. Each chemical the researchers investigated has been tested only in a small number of animal studies, with variability in the quality of those studies.

“While the evidence on the combined effects of chemicals and stress is new and emerging, it is clearly suggestive of an important question of social justice,” said co-author Rachel Morello-Frosch, a professor in the Department of Environmental Science, Policy and Management and the School of Public Health at UC Berkeley. “The bottom line is that poverty-related stress may make people more susceptible to the negative effects of environmental health hazards, and that needs to be a consideration for policymakers and regulators.”
