Long-haul aviation, like everything else in the human world, needs to be totally decarbonized, and in the race to zero emissions for international airliners, liquid-hydrogen powertrains look like one of the only viable possibilities.

Airbus is working on a number of hydrogen-powered aircraft, and it’s just found a new angle on cryogenic liquid H2 fuel: using it to supercool the powertrain down to superconducting temperatures, possibly unlocking huge weight and efficiency savings.

Today’s internal combustion engines in aircraft can be modified to run on alternative fuels for improved environmental performance. Now, hydrogen combustion—either via gas or liquid—is emerging as one of the most promising options in this respect. Airbus is exploring the technology’s potential in preparation for its zero-emission aircraft programme.

An attack has crippled the company’s operations—and cut off a large portion of the East Coast’s fuel supply—in an ominous development for critical infrastructure.

We have everything we need here Especially in Texas no one ever needs to freeze again if they come out of the Fossil Fuel stone age.

The idea is that when electric vehicles are not in use, the energy stored in their batteries is going to waste. If you make it possible for that energy to feed back into the grid, then it can help balance out dips in supply as renewables go offline, rather than relying on fossil-fuel plants to pick up the slack.

The technology that can make that happen is still in its infancy, though. When an electric vehicle is charged, the alternating current from the grid is converted to direct current that can be stored in its batteries. But most charging stations and cars don’t have the hardware to allow this process to run in reverse, meaning the power can’t be fed back into the grid.

Top U.S. fuel pipeline operator Colonial Pipeline has shut its entire network, the source of nearly half of the U.S. East Coast’s fuel supply, after a cyber attack that the company said was caused by ransomware.

The shutdown has raised fears of a price spike at the gas pumps ahead of peak demand summer driving season if it persists, and has drawn attention to how critical U.S. energy infrastructure is vulnerable to hackers.

Colonial transports 2.5 million barrels per day of gasoline, diesel, jet fuel and other refined products through 5500 miles (8850 km) of pipelines linking refiners on the Gulf Coast to the eastern and southern United States.

Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.

But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% efficient, and the precious metal catalysts used to accelerate the reaction, like platinum and iridium, are rare and expensive.

Now an international team led by scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory has developed a suite of advanced tools to break through this bottleneck and improve other energy-related processes, such as finding ways to make lithium-ion batteries charge faster. The research team described their work in Nature today.

The “graphene revolution” is almost here. Australian scientists specializing in aluminum-ion batteries are now working with Brisbane-based Graphene Manufacturing Group to commercialize a technology that could transform energy storage.

Coal is a highly polluting and expensive way to generate electricity. This analysis shows that we have economic alternatives to continuing to burn coal for power in the US. Furthermore, analyses such as “The 2035 Report” show that we can fully retire coal, stop building other fossil fuel plants (namely gas), and still reliably meet electricity demand, while providing a host of environmental and societal benefits. There are existing policies that can help policymakers closely examine the cost burden of generation resources used today, procure cheaper and cleaner generation resources going forward, and address current assets on the books. The continuation and intensification of the coal cost crossover demands attention from policymakers and consumers alike.

The costs of most existing US coal-fired power plants are now more expensive than the total costs of wind and solar.

Researchers have demonstrated a record-high laser pulse intensity of over 10²³ W/cm² using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It took more than a decade to reach this laser intensity, which is ten times that reported by a team at the University of Michigan in 2004. These ultrahigh intensity light pulses will enable exploration of complex interactions between light and matter in ways not possible before.

The powerful laser can be used to examine phenomena believed to be responsible for high-power cosmic rays, which have energies of more than a quadrillion (1015) electronvolts (eV). Although scientists know that these rays originate from somewhere outside our solar system, how they are made and what is forming them has been a longstanding mystery.

“This high intensity laser will allow us to examine astrophysical phenomena such as electron-photon and photon-photon scattering in the lab,” said Chang Hee Nam, director of CoReLS and professor at Gwangju Institute of Science & Technology. “We can use it to experimentally test and access theoretical ideas, some of which were first proposed almost a century ago.”
