A High-Energy Density And Long-Life Initial-Anode-Free Lithium Battery by Ingrid Fadelli

Lithium-metal batteries (LMBs), an emerging type of rechargeable lithium-based batteries made of solid-state metal instead of lithium-ions, are among the most promising high-energy-density rechargeable battery technologies. Although they have some advantageous characteristics, these batteries have several limitations, including a poor energy density and safety-related issues. In recent years, researchers have tried to overcome these limitations […]

Making Clean Hydrogen Is Hard, But Researchers Just Solved A Major Hurdle by University of Texas at Austin

For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source—splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low […]

May Gales Help Britain Set Record For Wind Power Generation by Julia Kollewe

In early hours of Friday, windfarm turbines provided nearly two-thirds of Britain’s electricity. Powerful gusts of wind sweeping across Britain have helped the country reach a new all-time high for electricity generated from wind turbines. A new record was set in the early hours of Friday for the share of wind power in the generation […]

First Nanoscale Look At A Reaction That Limits The Efficiency Of Generating Clean Hydrogen Fuel by Glennda Chu

Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen. But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% […]

Better Solutions For Making Hydrogen May Lie Just At The Surface by Christina Nunez, Argonne National Laboratory

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That’s because, even though hydrogen is abundant, it must be derived from another substance that contains it—and today, that substance is often methane gas. Scientists are seeking ways to isolate this energy-carrying element without using fossil […]

This Hydrogen Fuel Machine Could Be The Ultimate Guide To Self-Improvement by Lawrence Berkeley National Laboratory

Three years ago, scientists at the University of Michigan discovered an artificial photosynthesis device made of silicon and gallium nitride (Si/GaN) that harnesses sunlight into carbon-free hydrogen for fuel cells with twice the efficiency and stability of some previous technologies. Now, scientists at the Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab)-in collaboration […]

Agriculture And Fossil Fuels Are Driving Record-High Methane Emissions by Maria Temming

Africa and Asia have seen releases of the heat-trapping gas surge In 2017, human activities pumped about 364 million metric tons of methane into the atmosphere, compared with 324 million tons per year, on average, in the early 2000s. About half of that 12 percent increase was the result of expanding agriculture and landfills, while […]
