When experiments go quiet: maintaining the National Ignition Facility

For two weeks last April, the lasers at Lawrence Livermore National Laboratory’s National Ignition Facility stopped firing. Experiments may have been on pause, but the facility was anything but quiet. “To do world-class science, you need a world-class facility. And you can’t just maintain that facility, you must anticipate problems and seek out improvements,” said Stanley…

New technique converts excess renewable energy to natural gas

Four Lawrence Livermore National Laboratory (LLNL) researchers have partnered with Los Angeles-based SoCalGas and Munich, Germany-based Electrochaea to develop an electrobioreactor to allow excess renewable electricity from wind and solar sources to be stored in chemical bonds as renewable natural gas. When renewable electricity supply exceeds demand, electric-utility…

Hard as a rock, LLNL to study geologic hydrogen production

Lawrence Livermore National Laboratory (LLNL) has received $1 million to explore technologies that stimulate hydrogen production from mineral deposits found in the subsurface, including developing our understanding of hydrogen-producing geochemical reactions and how to enhance or control the rate of hydrogen production. The use of hydrogen fuel to offset fossil fuel…

HPC for Energy Innovation announces funding for new energy efficiency projects

The Department of Energy’s (DOE) High Performance Computing for Energy Innovation (HPC4EI) initiative today announced over $5 million in new funding for 13 industry partnerships, including a project led at Lawrence Livermore National Laboratory to develop more efficient optical cables.
