Do two promising structural materials corrode at very high temperatures when in contact with 'liquid metal fuel breeders' in fusion reactors? Researchers now have the answer. This high-temperature compatibility of reactor structural materials with the liquid breeder -- a lining around the reactor core that absorbs and traps the high energy neutrons produced in the plasma inside the reactor -- is key to the success of a fusion reactor design.

Researchers have developed a new type of catalyst material, called a metal hydroxide-organic framework (MHOF), which is made of inexpensive and abundant components. The catalyst speeds up the electrochemical reaction that splits apart water molecules to produce oxygen, which is at the heart of multiple approaches aiming to produce alternative fuels for transportation.

With the federal government planning to hold the largest sale of offshore wind farm leases in the nation's history, a new study could help inform the development of offshore wind farms by providing detailed models characterizing the frequency, intensity and height of low-level jet streams over the U.S. Atlantic coastal zone.

Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software to conduct a series of detailed theoretical studies of simplified airfoils with characteristics reminiscent of owl wings. They applied their findings to suppress the noise of rotating machinery. Improving the flow conditions around the trailing edge and optimizing the shape of the edge suppressed the noise.

Earth's global average surface temperature in 2021 tied with 2018 as the sixth warmest on record, according to independent analyses done by NASA and NOAA. Collectively, the past eight years are the warmest years since modern recordkeeping began in 1880.

A 'macrogrid' that increases the electricity moving between America's Eastern and Western interconnections, two of the biggest power grids on the planet, would more than pay for itself, according to new research.

With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources.

A day before world leaders meet at COP26 to discuss the importance of clean energy, scientists from across the UK say that harnessing the power of the ocean's tidal streams can provide a predictable and reliable means of helping to meet the country's future energy demand.

Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation's buildings entirely with renewable energy, according to a recent analysis.

Meteorologists and emergency workers continue to contest the popular thinking that waiting out a tornado under an overpass is safe. According to the National Weather Service, doing so could actually increase the risk of death, in part because the wind from a tornado is thought to accelerate as it flows under the overpass, in what's known as the wind tunnel effect.

The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in the journal Nature Energy, written by Aleh Cherp, Vadim Vinichenko, Jale Tosun, Joel A.Gordon and Jessica Jewell.

Hydropower is the dominant source of energy in the Amazon region, the world's largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the Amazon's hydropower capacity.

In recent years, much progress has been made in the wind energy industry as the cost of development has declined significantly with emerging technologies and incentive policies. Nevertheless, wind farms can be made more efficient. Researchers now examine diurnal and seasonal patterns of wind speeds and their impact on the adequacy of energy production. The results helped them develop a seasonal adequacy assessment procedure.

Implementing advance wind energy scenarios could achieve a reduction in global warming atmospheric average temperatures of 0.3 to 0.8 degrees Celsius by the end of the century, according to new research.
