'Underground battery' could store energy, CO2

Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use.The intermittency of when the wind blows and when the sun shines is one of the biggest challenges impeding…

Using hydrogen to enhance lithium ion batteries

Lawrence Livermore National Laboratory scientists have found that lithium ion batteries operate longer and faster when their electrodes are treated with hydrogen.Lithium ion batteries (LIBs) are a class of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.The growing demand…

American energy use up slightly, carbon emissions almost unchanged

Americans' energy use continued to grow slowly in 2014, fueled by increases in the use of natural gas, wind and solar, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory.Each year, the Laboratory releases charts that illustrate the nation's consumption and use of energy. Overall, Americans used 0.9 quadrillion (quads) British…

New research could lead to more efficient electrical energy storage

Lawrence Livermore researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored.The research could lead to an improvement in the capacity and efficiency of electrical energy storage systems, such as batteries and supercapacitors, needed to meet the burgeoning…

Microcapsules capture carbon safely

Using the same baking soda found in most grocery stores, Lawrence Livermore scientists, along with colleagues from Harvard University and the University of Illinois at Urbana-Champaign, have created a significant advance in carbon dioxide capture.The team developed a new type of carbon capture media composed of core-shell microcapsules, which consist of a highly permeable…

Physics World names National Ignition Facility fuel gain top 10 breakthrough of the year

Physics World, an international monthly magazine published by the Institute of Physics, has named the National Ignition Facility’s (NIF) achievement of fuel gain one of its top 10 breakthroughs of the year. Ignition — the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel — has long been considered the "holy grail" of…

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…
