Lawrence Livermore develops infrared camera system to view tokamak from the inside
LIVERMORE, Calif. – General Atomics’ DIII-D Tokamak has been a critical part of the nation’s magnetic fusion energy research since it was built in the 1980s.Over the years, wear and tear has taken its toll. However, it was impossible for researchers to see inside the San Diego company’s highly complicated machine to assess damage -- until now.Lawrence Livermore National…
Energy storage of the future
Personal electronics such as cell phones and laptops could get a boost from some of the lightest materials in the world.Lawrence Livermore researchers have turned to graphene aerogel for enhanced electrical energy storage that eventually could be used to smooth out power fluctuations in the energy grid.The team found that graphene aerogel-based supercapacitor electrodes…
New project is the ACME of addressing climate change
High performance computing (HPC) will be used to develop and apply the most complete climate and Earth system model to address the most challenging and demanding climate change issues. Eight national laboratories, including Lawrence Livermore, are combining forces with the National Center for Atmospheric Research, four academic institutions and one private-sector company…
Heading toward the hydrogen highway
Lawrence Livermore scientists are working on a project that will use particles considerably smaller than the size of a human hair to improve the storage capacity of hydrogen-powered vehicles.Using $1.2 million from the Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) over three years, LLNL scientist Brandon Wood said that through theory and…
Americans using more energy according to Lawrence Livermore analysis
Americans used more renewable, fossil and even nuclear energy in 2013, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory.Each year, the Laboratory releases energy flow charts that illustrate the nation's consumption and use of energy. Overall, Americans used 2.3 quadrillion thermal units more in 2013 than the previous year…
LLNL scientists find precipitation, global warming link
The rain in Spain may lie mainly on the plain, but the location and intensity of that rain is changing not only in Spain but around the globe.A new study by Lawrence Livermore National Laboratory scientists shows that observed changes in global (ocean and land) precipitation are directly affected by human activities and cannot be explained by natural variability alone. The…
Lawrence Livermore study finds human activity affects vertical structure of atmospheric temperature
Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of…
Lawrence Livermore engineering team makes breakthrough in solar energy research
LIVERMORE, Calif. - The use of plasmonic black metals could someday provide a pathway to more efficient photovoltaics (PV) -- the use of solar panels containing photovoltaic solar cells -- to improve solar energy harvesting, according to researchers at Lawrence Livermore National Laboratory (LLNL).The LLNL Materials Engineering Division (MED) research team has made…
Lawrence Livermore celebrates 25 years of carbon dating
From developing the first accelerator mass spectrometer for use in the biology field to tracking radionuclides from the Dai-ichi Nuclear Power Plant disaster, the Laboratory's Center for Accelerator Mass Spectrometry (CAMS) has spent 25 years in the spotlight of not only dating ancient artifacts but solving global challenges.CAMS is celebrating its 25th anniversary this…
Carbon dating impacts non-proliferation, drug research and climate change
Research conducted at the Center for Accelerator Mass Spectrometry (CAMS) spans the universe, the depths of time and everything in between. Although not all elements and isotopes are able to be utilized by AMS, CAMS' researchers make the most of what nuclear physics has given them.Here is a sampling of some of the many ways CAMS is utilized, along with the important…
Americans continue to use more renewable energy sources
Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012, according to the most recent U.S. energy charts released by Lawrence Livermore National Laboratory . Each year, the Laboratory releases energy flow charts that track the nation's consumption of energy resources. Natural gas use is up particularly in the…
Livermore develops the world's deepest ERT imaging system for CO2 sequestration
LIVERMORE, Calif.-- Lawrence Livermore National Laboratory researchers have broken the record for tracking the movement and concentration of carbon dioxide in a geologic formation using the world's deepest Electrical Resistance Tomography (ERT) system.The research provides insight into the effects of geological sequestration to mitigate the impact of greenhouse gases.The…
Livermore scientists develop CO2 sequestration technique that produces 'supergreen' hydrogen fuel, offsets ocean acidification
LIVERMORE, Calif. -- Lawrence Livermore scientists have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification.The team demonstrated, at a laboratory scale, a system that uses the acidity normally produced in saline water…
Lab partners with Navajo Nation on uranium mine project
A team of Lab scientists last month visited the Navajo Nation Abandoned Mine Lands Reclamation Project (Navajo AML) in Shiprock, N.M. to conduct work on a joint project. The partnership will develop an environmental and hydrological monitoring program for a uranium mine waste disposal cell in the Tse Tah area of northeast Arizona and several other mining areas. The Lab…
CES-21 board meets at Lawrence Livermore
The California Energy System for the 21st Century (CES-21) Board of Directors convened their latest public meeting at Livermore Valley Open Campus (LVOC) last Thursday. Following welcoming remarks by Computation Associate Director Dona Crawford and comments by CES-21 Executive Director Steve Larson, the board began the process of reviewing different aspects of the pending…
Lawrence Livermore scientists discover new materials to capture methane
Scientists at Lawrence Livermore National Laboratory (LLNL) and UC Berkeley and have discovered new materials to capture methane, the second-highest concentration greenhouse gas emitted into Earth's atmosphere. Methane is a substantial driver of global climate change, contributing 30 percent of current net climate warming. Concern over methane is mounting, due to leaks…
