The massive natural gas leak at Aliso Canyon shined a light on California’s aging natural gas infrastructure. And five years of extreme drought also exacted its toll on transmission pipelines. Now the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has been awarded $4.6 million by the California Energy Commission for two projects aimed at improving the safety and reliability of the state’s natural gas system.

U.S. energy production could increase with the help of an improved carbon capture technology that use about half the energy of today's standard technologies. Emissions captured at fossil fuel power plants could in turn be used to harvest more crude by injecting it into underground oil fields.

Modern batteries power everything from cars to cell phones, but they are far from perfect – they catch fire, they perform poorly in cold weather and they have relatively short lifecycles, among other issues. Now researchers from the University of Houston have described a new class of material that addresses many of those concerns in Nature Materials.

Simon Fraser University researchers are developing a tiny power source that activates with only a few drops of water and can provide instant power up to 100 minutes before being tossed away.

The patent-pending biodegradable PowerPAD (Power: Portable And Disposable) is a single-use disposable battery—a mere inch in diameter—in which water stimulates a chemical reaction that changes the oxidization of its atoms.

The long range of airborne drones helps them perform critical tasks in the skies. Now MIT spinout Open Water Power (OWP) aims to greatly improve the range of unpiloted underwater vehicles (UUVs), helping them better perform in a range of applications under the sea.

Recently acquired by major tech firm L3 Technologies, OWP has developed a novel aluminum-water power system that’s safer and more durable, and that gives UUVs a tenfold increase in range over traditional lithium-ion batteries used for the same applications.

Engineers at the University of California San Diego have developed a breakthrough in electrolyte chemistry that enables lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance — in comparison, today’s lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as low as -80 degrees Celsius — their current low temperature limit is -40 degrees Celsius. While the technology enables extreme low temperature operation, high performance at room temperature is still maintained. The new electrolyte chemistry could also increase the energy density and improve the safety of lithium batteries and electrochemical capacitors.

In the UK alone, some 1.5 million homes are equipped with solar panels, and it has been estimated that by 2020 the figure could soar to 10 million, with the prospect of lower energy bills for consumers and massive reductions in CO2emissions. Now, a University of Huddersfield researcher is developing new technologies that could enable clusters of houses to share their solar energy, rather than simply exporting surplus electricity to the national grid. Also, new systems for fault detection will enable householders to monitor and maintain the efficiency of their panels.

Hundreds of built and proposed hydroelectric dams may significantly harm life in and around the Amazon by trapping the flow of rich nutrients and modifying the climate from Central America to the Gulf of Mexico. These findings, published in Nature, emerge from a multidisciplinary, international collaboration of researchers from 10 universities, led by scientists at The University of Texas at Austin.

To meet energy needs, economic developers in South America have proposed 428 hydroelectric dams, with 140 currently built or under construction, in the Amazon basin — the largest and most complex network of river channels in the world, which sustains the highest biodiversity on Earth. The rivers and surrounding forests are the source of 20 percent of the planet’s fresh water and valuable ingredients used in modern medicine. 

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles.

Now Stanford University scientists have overcome a major hurdle to such a future by wirelessly transmitting electricity to a nearby moving object. Their results are published in the June 15 edition of Nature.

“In addition to advancing the wireless charging of vehicles and personal devices like cellphones, our new technology may untether robotics in manufacturing, which also are on the move,” said Shanhui Fan, a professor of electrical engineering and senior author of the study. “We still need to significantly increase the amount of electricity being transferred to charge electric cars, but we may not need to push the distance too much more.”

Global consumption of coal fell by a record amount last year, driven by a rise in natural gas, increasing deployment of wind and solar power, and a shift in China away from heavy industry, according to BP’s global review of energy trends.
