Today wirelessly connected devices are performing an expanding array of applications, such as monitoring the condition of engines and machinery and remote sensing in agricultural settings. Systems known as the “Internet of Things” (IoT), hold much potential for improving the efficiency and safety of the equipment. Yet stumbling blocks remain for IoT, thwarting many potential …

Imagine a vast volume of porous sandstone reservoir, once full of oil and natural gas, now full of a different, carbon-free fuel — hydrogen. Scientists at Sandia National Laboratories are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing this carbon-free fuel. Hydrogen is …

In an era where the quest for sustainable energy sources has become paramount, researchers are tirelessly exploring innovative avenues to enhance fuel production processes. One of the most important tools in converting chemical energy into electrical energy and vice versa is electrocatalysis, which is already used in various green-energy technologies. Electrocatalysis speeds up electrochemical reactions …

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. …

If you imagine an industrial wind turbine, you likely picture the windmill design, technically known as a horizontal-axis wind turbine (HAWT). But the very first wind turbines, which were developed in the Middle East around the 8th century for grinding grain, were vertical-axis wind turbines (VAWT), meaning they spun perpendicular to the wind, rather than …

Researchers in the UNC-Chapel Hill Chemistry Department are using semiconductors to harvest and convert the sun’s energy into high-energy compounds that have the potential to produce environmentally friendly fuels. In the paper, “Methyl Termination of p-Type Silicon Enables Selective Photoelectrochemical CO2 Reduction by a Molecular Ruthenium Catalyst,” published in ACS Energy Letters, the researchers explain …

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A Washington State University-led study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar …

Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels. An international team of researchers from the University of Nottingham’s School of Chemistry, University of Birmingham, University of Queensland and University of Ulm have …

Pairing cryptocurrency mining — notable for its outsize consumption of carbon-based fuel — with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new Cornell University study. “Since current cryptocurrency operations now contribute heavily to worldwide carbon emissions, it becomes vital to explore …

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and the University of North Carolina Chapel Hill (UNC) have demonstrated the selective conversion of carbon dioxide (CO2) into methanol using a cascade reaction strategy. The two-part process is powered by sunlight, occurs at room temperature and at ambient pressure, and employs a recyclable …

The solar energy world is ready for a revolution. Scientists are racing to develop a new type of solar cell using materials that can convert electricity more efficiently than today’s panels. In a new paper published February 26 in the journal Nature Energy, a University of Colorado Boulder researcher and his international collaborators unveiled an …

Scientists are always on the lookout for ways to make our world a better place, and one area they’re focusing on is solar energy. One idea in this area is to make solar cells more efficient by concentrating more solar light onto them. While investigating this recently, a group of scientists at the Cavendish Laboratory …
