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 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.
Published Lignin-based jet fuel packs more power for less pollution
(via sciencedaily.com) An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds added to conventional fuels, according to new research.
Published Cheaper hydrogen fuel cell could mean better green energy options
(via sciencedaily.com) Researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum, enabling greater use of the technology.
Published Study finds offshore wind could drive down energy costs in New England, US
(via sciencedaily.com) While wind power is expected to be a 'saving grace' during extreme winter storms, researchers wanted to look at whether storms could also disrupt power supplies and drive up prices.
Published Key to improved green tech efficiency found in simple acid treatment
(via sciencedaily.com) The development of new, more efficient electrochemical cells could provide a good option for carbon-free hydrogen and chemical production along with large-scale electricity generation and storage. But first, scientists must overcome several challenges, including how to make the cells more efficient and cost-effective.
Published Extract from a common kitchen spice could be key to greener, more efficient fuel cells
(via sciencedaily.com) Researchers have discovered a novel way to combine curcumin -- the substance in turmeric -- and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.
Published You've heard of water droughts. Could 'energy' droughts be next?
(via sciencedaily.com) Drawing on 70 years of historic wind and solar-power data, researchers built an AI model to predict the probability of a network-scale 'drought,' when daily production of renewables fell below a target threshold. Under a threshold set at the 30th percentile, when roughly a third of all days are low-production days, the researchers found that Texas could face a daily energy drought for up to four months straight. Batteries would be unable to compensate for a drought of this length, and if the system relied on solar energy alone, the drought could be expected to last twice as long -- for eight months.
Published Lack of marshaling ports hindering offshore wind industry
(via sciencedaily.com) A new study finds that the nation's existing and planned marshaling ports, the assembly areas critical to building and deploying offshore wind turbines, will be insufficient by 2023 to meet commitments and will fail to meet projected demand through 2050.
Published Collision hotspots for migrating birds revealed in new study
(via sciencedaily.com) New research highlights the areas in Europe and North Africa where the construction of wind turbines or power lines is likely to increase the risk of death for migrating birds.
Published Scavenger nanoparticles could make fuel cell-powered vehicles a reality
(via sciencedaily.com) Engineers have developed a material that could give fuel cell systems a competitive edge over the battery systems that currently power most electric vehicles.
