New paper examines hydrogen at high pressure


Hydrogen is the most abundant element found in the universe, making up nearly three-quarters of all matter. Despite its prevalence, questions about the element remain. In a new paper published by Nature Communications, a team of researchers, including scientists from Lawrence Livermore National ...


Researchers move one step closer to sustainable hydrogen production


Splitting water into its hydrogen and oxygen parts may sound like science fiction, but it's the end goal of chemists and chemical engineers like Christopher Murray of the University of Pennsylvania and Matteo Cargnello of Stanford University. They work in a field called photocatalysis, which, at ...

Phosphine as a superconductor?

Sure, but the story may be complicated


Phosphine is one of the newest materials to be named a superconductor, a material through which electricity can flow with zero resistance. In 2015, scientists reported that they had liquefied the chemical and squeezed it under high pressure in a diamond vice to achieve superconductivity. Now, a ...


Speeding up the hydrogen highway

HyStEP device will accelerate hydrogen refueling station commissioning


Drivers are seeing more hydrogen fuel cell electric vehicles (FCEVs) on the road, but refueling stations for those vehicles are still few and far between. This is about to change, and one reason is a new testing device being validated at California refueling stations that will greatly accelerate ...


'Hydricity' concept uses solar energy to produce power round-the-clock


Researchers are proposing a new "hydricity" concept aimed at creating a sustainable economy by not only generating electricity with solar energy but also producing and storing hydrogen from superheated water for round-the-clock power production. "The proposed hydricity concept represents a ...


Using hydrogen to enhance lithium ion batteries

Lithium ion batteries operate longer and faster when 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 for energy storage emphasizes the urgent need for higher-performance batteries. ...


It's solid: Storing hydrogen in a new form


As part of a tri-lab consortium, Lawrence Livermore National Laboratory researchers will develop tools and understanding necessary for designing new solid-state materials for storing hydrogen gas. Storage of hydrogen onboard vehicles is one of the critical enabling technologies for ...

Discovery of a highly efficient catalyst eases way to hydrogen economy


Hydrogen is usually produced by separating water with electrical power. And although the water supply is essentially limitless, a major roadblock to a future "hydrogen economy" is the need for platinum or other expensive noble metals in the water-splitting devices.Noble metals resist oxidation ...

Chemists find new way to do light-driven reactions in solar energy quest

The more efficient method opens another possible pathway to harness sunlight for energy


Chemists have found a new, more efficient method to perform light-driven reactions, opening up another possible pathway to harness sunlight for energy. The journal Science is publishing the new method, which is based on plasmon - a special motion of electrons involved in the optical properties of ...


NIST calculates high cost of hydrogen pipelines, shows how to reduce it


The National Institute of Standards and Technology (NIST) has put firm numbers on the high costs of installing pipelines to transport hydrogen fuel - and also found a way to reduce those costs.Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to ...
