Published Hurricanes and power grids: Eliminating large-scale outages with a new approach



Large scale-power outages caused by tropical cyclones can be prevented almost entirely if a small but critical set of power lines is protected against storm damages, a new study finds. Scientists developed a new method that can be used to identify those critical lines and increase the system's resilience.
Published Improving energy security with policies focused on demand-side solutions



Energy systems essential to supporting our everyday activities face increasing threats from wars, pandemics, climate change, and other unexpected events. An international team of researchers found that demand-oriented solutions have a significantly greater potential to reduce our vulnerability to energy crises compared to supply measures.
Published Researchers look at environmental impacts of AI tools



As artificial intelligence (AI) is increasingly used in radiology, researchers caution that it's essential to consider the environmental impact of AI tools.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops



In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency



Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published Imaging grain boundaries that impede lithium-ion migration in solid-state batteries



A research team has developed a new technique to image grain boundaries obstructing lithium-ion migration in solid-state batteries -- a promising type of next-generation battery.
Published What will it take for China to reach carbon neutrality by 2060?



To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.
Published New world record for CIGS solar cells



A new record for electrical energy generation from CIGS solar cells has been reached. Scientists have achieved a 23.64 percent efficiency.
Published Researchers harness 2D magnetic materials for energy-efficient computing



Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.
Published A new vibrant blue pottery pigment with less cobalt



Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Published Method identified to double computer processing speeds



Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.
Published New water batteries stay cool under pressure



A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
Published Road to better performing batteries using less critical raw materials



Researchers are developing batteries that can charge faster, offer more stable storage and are made of sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2 -footprint.
Published Physicists develop more efficient solar cell



Physicists have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the increase in efficiency.
Published Electrification or hydrogen? Both have distinct roles in the European energy transition



A key step to achieving climate neutrality in the European Union is to rapidly shift from fossil fuels to electric technologies powered by renewable energies, a new study shows. At the same time, hydrogen produced from electricity will also be indispensable in hard-to-electrify sectors such as aviation, shipping and chemicals. By 2050, electrification and hydrogen are the key strategies to reach climate neutrality based on renewable power.
Published New chip opens door to AI computing at light speed



Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.
Published Discovery of new Li ion conductor unlocks new direction for sustainable batteries



Researchers have discovered a solid material that rapidly conducts lithium ions. Consisting of non-toxic earth-abundant elements, the new material has high enough Li ion conductivity to replace the liquid electrolytes in current Li ion battery technology, improving safety and energy capacity. The research team have synthesized the material in the laboratory, determined its structure and demonstrated it in a battery cell.
Published 'Scientists' warning' on climate and technology



Throughout human history, technologies have been used to make peoples' lives richer and more comfortable, but they have also contributed to a global crisis threatening Earth's climate, ecosystems and even our own survival. Researchers have suggested that industrial civilization's best way forward may entail embracing further technological advancements but doing so with greater awareness of their potential drawbacks.
Published Benefits of heat pumps



Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition.
Published Eco-friendly way to generate power from waste wood



A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
