Using electricity generated by offshore wind turbines as one pathway to split water to produce clean hydrogen may make economic sense, particularly along the U.S. Atlantic Coast and in the Gulf of Mexico, according to researchers at the National Renewable Energy Laboratory (NREL).... Read more

Researchers at Songshan Lake Materials Laboratory have made significant advances in sodium-ion battery (SIB) technology by improving cycling performance of the NaNiO2 cathode. The work has been published in the online edition of Materials Futures.... Read more

Water electrolysis offers an ideal process for hydrogen production, which could play a key role in the global energy transition that increasingly relies on renewable electricity, but whose current production process is extremely carbon intensive.... Read more

The power-conversion efficiencies (PCEs) of organic solar cells based on compounds known as polymer donors and fused ring electron acceptors (FREAs) have recently exceeded 19%. In contrast, organic solar cells based on non-fused ring electron acceptors (NFREAs), more affordable compounds characterized by non-fused (i.e., separate) aromatic rings, have so far... Read more

Researchers at Oak Ridge National Laboratory have opened a new virtual library where visitors can check out waveforms instead of books.... Read more

The element lithium is used widely in batteries because it results in long-lasting, stable energy storage. However, it's a finite resource, so researchers are hard at work trying to identify alternate materials to use in battery production. Using the Canadian Light Source at the University of Saskatchewan, a team from... Read more

Researchers are using AI and satellite technologies to make the continent's renewable energy infrastructure more reliable.... Read more

The artificial intelligence boom has had such a profound effect on big tech companies that their energy consumption, and with it their carbon emissions, have surged.... Read more

Los Angeles residents and businesses will face higher electric bills as the Department of Water and Power transitions to 100% clean energy, according to a report by the city's Office of Public Accountability.... Read more

China is building almost twice as much wind and solar energy capacity as every other country combined, research published Thursday showed.... Read more

Solar energy is critical for a clean-energy future. Traditionally, solar energy is harvested using silicon—the same semiconductor material used in everyday electronic devices. But silicon solar panels have drawbacks: for instance, they're expensive and hard to mount on curved surfaces.... Read more

Solid-state batteries have several advantages: They can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way.... Read more

Ghana is considering bids from five companies for the construction of what would be its first nuclear power plant. The companies are: France's EDF, US-based NuScale Power and Regnum Technology Group; China National Nuclear Corporation; South Korea's Kepco and its subsidiary Korea Hydro Nuclear Power Corporation; and Russia's Rosatom. The... Read more

Silicon dominates the current commercial solar cell industry, offering an attractive combination of low cost, high efficiency and long lifespan.... Read more

A team led by Prof. Wu Zhengyan and Zhang Jia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has synthesized a versatile, broad-spectrum Fe/Cu primary battery-based nanocomposite with photo-induced protonation effect to immobilize diverse heavy metal ions. This system has a large number of active... Read more
