Published Scientists discover phenomenon impacting Earth's radiation belts
(via sciencedaily.com) Original source Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm
(via sciencedaily.com) Original source On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published A method that paves the way for improved fuel cell vehicles
(via sciencedaily.com) Original source More efficient and longer-lasting fuel cells are essential for fuel cell-powered heavy-duty hydrogen vehicles to be an alternative to combustion fuelled counterparts. Researchers have developed an innovative method to study and understand how parts of fuel cells degrade over time. This is an important step towards the improved performance of fuel cells and them becoming commercially successful.
Published Win-win potential of grass-powered energy production
(via sciencedaily.com) Original source Researchers modeled the impact of using anaerobic digestion to produce renewable natural gas from grassy biomass in different settings and from varying perspectives, analysis that helps flesh out the system's potential.
Published New dawn for space storm alerts could help shield Earth's tech
(via sciencedaily.com) Original source Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published Study shows new efficiency standards for heavy trucks could boost energy use
(via sciencedaily.com) Original source A new study suggests that the U.S. government's push to increase heavy-duty trucks' energy efficiency could encourage more shipping by truck instead of rail, reducing the policies' anticipated effectiveness by 20%.
Published Hydrogen flight looks ready for take-off with new advances
(via sciencedaily.com) Original source The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.
Published Pinpointing coal plants to convert to nuclear energy, considering both practicality and community support
(via sciencedaily.com) Original source An assessment ranks the feasibility of converting 245 operational coal power plants in the U.S. into advanced nuclear reactors, providing valuable insights for policymakers and utilities to meet decarbonization goals, according to a new study.
Published A 'liquid battery' advance
(via sciencedaily.com) Original source A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
Published Innovative demand strategies for clean energy
(via sciencedaily.com) Original source A perspective piece describes innovative strategies that significantly reduce both resource consumption and fossil fuel emissions.
Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published The origin of the sun's magnetic field could lie close to its surface
(via sciencedaily.com) Original source Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's outermost layers. If confirmed, the findings could help scientists better predict space weather.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published Studying bubbles can lead to more efficient biofuel motors
(via sciencedaily.com) Original source By studying how bubbles form in a drop of biodiesel, researchers can help future engines get the most energy out of the fuel.
Published The price tag of phasing-out coal
(via sciencedaily.com) Original source Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.
Published Methane emissions from landfill could be turned into sustainable jet fuel in plasma chemistry leap
(via sciencedaily.com) Original source Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.
Published Coal train pollution increases health risks and disparities
(via sciencedaily.com) Original source The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.
Published Researchers can help shipowners achieve ambitious climate targets
(via sciencedaily.com) Original source International shipping does not want to be a climate bad guy and is aiming to be emission-free by 2050. A new tool can help shipowners who are searching for green solutions.
Published Subterranean storage of hydrogen
(via sciencedaily.com) Original source Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Published Tracing the largest solar storm in modern times from tree rings in Lapland
(via sciencedaily.com) Original source A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
