Published A 'liquid battery' advance



A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
Published Algae offer real potential as a renewable electricity source



The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Some countries could meet their total electricity needs from floating solar panels



Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Enhancing nanofibrous acoustic energy harvesters with artificial intelligence



Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
Published New method makes hydrogen from solar power and agricultural waste



Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published Wind farms are cheaper than you think -- and could have prevented Fukushima, says global review



Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy.
Published What are the risks of hydrogen vehicles in tunnels?



A team has analyzed the risk and damage potential of hydrogen vehicles in tunnels and derived recommendations. Their conclusion? Any damage would be extensive, but its occurrence is unlikely.
Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency



Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published Subduction zone splay faults compound hazards of great earthquakes



Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis.
Published New data-driven model rapidly predicts dehydrogenation barriers in solid-state materials



Researchers have developed a groundbreaking data-driven model to predict the dehydrogenation barriers of magnesium hydride, a promising material for solid-state hydrogen storage. This advancement holds significant potential for enhancing hydrogen storage technologies, a crucial component in the transition to sustainable energy solutions.
Published More efficient bioethanol production might be possible using persimmon tannin to help yeast thrive



Researchers have found that persimmon tannin, known for its antioxidant properties, improves the growth of yeast in the presence of ethanol.
Published Wind farms can offset their emissions within two years



After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
Published Shedding light on perovskite hydrides using a new deposition technique



Perovskite hydrides are promising materials for various emerging energy technologies, but measuring their intrinsic hydride-ion conductivity is difficult. In a recent study, researchers address this issue using a novel laser deposition technique in an H-radical atmosphere. Using this approach, they grew thin-film single crystals of two different perovskite hydrides and characterized their hydride-ion conductivity. These efforts will bolster research on hydrogen-related materials.
Published Promising new development in solar cell technology



Researchers who contributed to the development of record-breaking solar cells a few years ago, expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells.
Published Scientists generate heat over 1,000 degrees Celsius with solar power instead of fossil fuel



Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000 C (1,832 F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.
Published Manganese sprinkled with iridium: a quantum leap in green hydrogen production



Researchers report a new method that reduces the amount of iridium needed to produce hydrogen from water by 95%, without altering the rate of hydrogen production. This breakthrough could revolutionize our ability to produce ecologically friendly hydrogen and help usher in a carbon-neutral hydrogen economy.
Published Efficacy of solar panels boosted



Solar energy is a crucial asset in the fight against climate change, and researchers have now devised a smart approach to optimize its effectiveness. Their innovative method includes incorporating artificial ground reflectors, a simple yet powerful enhancement.
Published Low-energy process for high-performance solar cells



Finding reliable, eco-friendly power sources is crucial as our world grapples with increasing energy needs and the urgent call to combat climate change. Solar energy offers one solution, with scientists devising ever more efficient materials for capturing sunlight.
Published Lake tsunamis pose significant threat under warming climate



The names might not be familiar -- Cowee Creek, Brabazon Range, Upper Pederson Lagoon -- but they mark the sites of recent lake tsunamis, a phenomenon that is increasingly common in Alaska, British Columbia and other regions with mountain glaciers. Triggered by landslides into small bodies of water, most of these tsunamis have occurred in remote locations so far, but geologists say it may just be a matter of time before a tsunami swamps a more populated place.
Published Path to easier recycling of solar modules



The use of femtosecond lasers to form glass-to-glass welds for solar modules would make the panels easier to recycle, according to a proof-of-concept study.
