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.
Published New method purifies hydrogen from heavy carbon monoxide mixtures
(via sciencedaily.com) Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. Chemical engineers have now demonstrated that the process can be simplified using a pump outfitted with newly developed membrane materials.
Published Fuel from waste wood
(via sciencedaily.com) According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation.
Published Researchers investigate development of coastal peatland in Indonesia over thousands of years
(via sciencedaily.com) Tropical peatlands are one of the most efficient carbon sinks. The flipside is that they can become massive emitters of carbon if they are damaged, for instance by land use change, degradation or fire. This can lead to faster climate warming. Researchers now show how peatland in the coastal areas in Sumatra and Borneo in Indonesia developed over thousands of years and how climate and sea level influenced their dynamics throughout.
Published Carbon-coated nickel enables fuel cell free of precious metals
(via sciencedaily.com) A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, researchers have found.
Published The opto-ionic effect: Light may increase performance of fuel cells and lithium-ion batteries
(via sciencedaily.com) Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly. But there a large number of obstacles to such mobility. Researchers have now shown that light can be used to increase the mobility of ions and improve the performance of such devices.
Published Bionic wing flaps improve wind energy efficiency
(via sciencedaily.com) Scientists show a bionic approach combining features of a seagull's wing with an engineered flow control accessory, known as a Gurney flap, can greatly improve wind turbine performance. To achieve the best aerodynamic performance, the scientists simulated the use of the combined flow control accessory in a variety of situations, including high and low angle of attack and pre- and post-stall scenarios. They compared their computational simulations to experimental results for an aircraft wing undergoing a dynamic stall.
Published Wind, solar could replace coal power in Texas
(via sciencedaily.com) A fraction of the wind and solar projects already proposed in Texas could eliminate the state's remaining coal power plants and their emissions, according to engineers.
Published Cheaper, more efficient ways to capture carbon
(via sciencedaily.com) Researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing heat-trapping gases from the atmosphere and converting them into beneficial substances, like fuel or building materials.
Published Making green energy greener: Researchers propose method for wind turbine blades' recycling
(via sciencedaily.com) Wind turbine blades made from glass fiber-reinforced polymer (GFRP) laminate composites can serve for up to 25 years. After that, they end up in landfills which has become a real challenge for the renewable energy industry. Researchers have proposed a method for wind turbine blades' recycling. Using pyrolysis, they broke the composite materials into their constituent parts. According to scientists, the extracted materials can be reused, and the process is virtually waste-free.
