Published Earth-abundant solar pixels found to produce hydrogen for weeks
(via sciencedaily.com) Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks -- according to new research. The findings could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
Published Ancient ocean floors could help in the search for critical minerals
(via sciencedaily.com) Studying ancient ocean floors could help us discover minerals needed to produce electric cars and solar panels.
Published A 3400-year-old city emerges from the Tigris River
(via sciencedaily.com) Archaeologists have uncovered a 3400-year-old Mittani Empire-era city once located on the Tigris River. The settlement emerged from the waters of the Mosul reservoir early this year as water levels fell rapidly due to extreme drought in Iraq. The extensive city with a palace and several large buildings could be ancient Zakhiku -- believed to have been an important center in the Mittani Empire (ca. 1550-1350 BC).
Published Famous rock art cave in Spain was used by ancient humans for over 50,000 years
(via sciencedaily.com) Original source A cave in southern Spain was used by ancient humans as a canvas for artwork and as a burial place for over 50,000 years, according to a new study.
Published Wind turbines operating without curtailment claim many victims among protected bat species in Germany
(via sciencedaily.com) Protected and rare bats regularly die at wind turbines (WT). This is why the operation of new wind turbines is temporarily curtailed during periods of high bat activity. Old wind turbines run without curtailment, however. A scientific team has now produced an exemplary estimate of bat fatality rates at such old turbines by systematically recording bat carcasses in the vicinity of the turbines. During two months, 70 bats died on average per wind turbine. Even if these figures cannot be extrapolated one-to-one to all 20,000 old turbines in Germany, there is a considerable need for action. The operation of old turbines should be adjusted to the current regulations for new turbines, the authors argue.
Published As the grid adds wind power, researchers have to reengineer recovery from power outages
(via sciencedaily.com) When electric grids go down, there's no way to restore them -- 'blackstart' them -- with power from wind turbines. A team is now working to develop strategies and controllers that would reenergize power grids dominated by wind power. In Iowa, wind turbines now produce 55% of the state's electricity.
Published Archaeologists reveal pre-Hispanic cities in Bolivia with laser technology
(via sciencedaily.com) Original source Several hundred settlements from the time between 500 and 1400 AD lie in the Bolivian Llanos de Mojos savannah and have fascinated archaeologists for years. Researchers have now visualized the dimensions of the largest known settlement of the so-called Casarabe culture. Mapping with the laser technology LIDAR indicates that it is an early urbanism with a low population density -- the only known case so far from the Amazon lowlands. The results shed new light on how globally widespread and diverse early urban life was and how earlier societies lived in the Amazon.
Published Researchers develop new biobattery for hydrogen storage
(via sciencedaily.com) A team of microbiologists has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest of climate protection.
Published Experts forecast the wind plant of the future to be taller and more economical
(via sciencedaily.com) Anticipating key features of wind plants a decade or more ahead of their installation can inform today's investment, research, and energy system planning decisions. Researchers elicited opinions from more than 140 of the world's leading experts about their expectations of future wind plant design in 2035.
Published New tech aims to drive down costs of hydrogen fuel
(via sciencedaily.com) Researchers have developed a new technique for extracting hydrogen gas from liquid carriers which is faster, less expensive and more energy efficient than previous approaches.
Published Hydrogen production method opens up clean energy possibilities
(via sciencedaily.com) A new energy-efficient way to produce hydrogen gas from ethanol and water has the potential to make clean hydrogen fuel a more viable alternative for gasoline to power cars.
Published Sparking sustainable new chemical catalysts
(via sciencedaily.com) New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation.
Published Improved wind forecasts save consumers millions in energy costs
(via sciencedaily.com) Scientists determined that by increasing the accuracy of weather forecasts over the last decade, consumers netted at least $384 million in energy savings. The researchers based their predictions on NOAA's High Resolution Rapid Refresh model, which provides daily weather forecasts for every part of the U.S. These include wind speed and direction data, which utilities can use to gauge how much energy their turbines will produce.
Published Scientists show how to store liquid fuels in polymeric gels to prevent explosions and fires
(via sciencedaily.com) Liquid fuels with high energy density, though used worldwide, are dangerous to transport and store owing to their volatility, which produces explosive gas mixtures. To address this problem, researchers recently investigated the possibility of storing liquid fuel within polymeric gel networks, preventing their fast evaporation, and demonstrating good combustion performance. Their work paves the way for safer transport and storage of liquid fuels.
Published Scientists advance renewable hydrogen production method
(via sciencedaily.com) Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.
Published The mystery solved about the active phase in catalytic carbon dioxide reduction to methanol
(via sciencedaily.com) Researchers have been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. A better knowledge of the catalytic process and the possibility of finding even more efficient materials opens the door for a green transition in the chemical industry.
Published Rapid adaptation of deep learning teaches drones to survive any weather
(via sciencedaily.com) Neural-Fly technology could one day build the future of package delivery drones and flying cars.
