Upgrading the vanadium redox battery
Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research ...
'Amplified' nanotubes may power the future
Rice University scientists have achieved a pivotal breakthrough in the development of a cable that will make an efficient electric grid of the future possible.
How to choose a catalyst: Predicting which materials will perform best in fuel cells and metal air batteries
MIT researchers have found a new way to predict which materials will perform best as catalysts for oxygen reduction, a core process in metal air batteries and fuel cells, opening up the possibility of faster ...
Applying lessons learned from one of the biggest blackouts in history
(Phys.org) —On a warm afternoon in August 2003, in rural Ohio, a high-voltage power line brushed against some untrimmed tree limbs. The action tripped a relay that immediately shut off the power it was ...
Engineers use brain cells to power smart grid
(Phys.org) —The unmatched ability of the human brain to process and make sense of large amounts of complex data has caught the attention of engineers working in the field of control systems.
Energy storage seen as next step for 'green' power
First, Randy Ross bought a Chevrolet Volt. Faced with the need to charge his car and eager to cut his utility bill, he installed solar panels on the roof of his Pleasanton, Calif., home.
The grid of the future
The outlet in your living room doesn't know a lot—yet. Unaware of whether they are drawing power from wind, solar, gas, or coal plants, the electrical lines that bring us power in many ways still resemble ...
Wireless networks exposed as electricity grid weakest link
Smarter, more efficient electricity meters aim to revolutionise energy distribution but WA researchers fear hackers could easily exploit numerous security flaws and wreck havoc on power grids.
Wind farms can provide society a surplus of reliable clean energy, study finds
The worldwide demand for solar and wind power continues to skyrocket. Since 2009, global solar photovoltaic installations have increased about 40 percent a year on average, and the installed capacity of wind ...
New material holds big energy hope
(Phys.org) —A new material that can store large amounts of energy with very little energy loss has been developed by researchers at the Australian National University.
Biggest solar storm since 2005 pummels Earth
A potent solar flare has unleashed the biggest radiation storm since 2005 and could disrupt some satellite communications in the polar regions, US space weather monitors said Monday.
Satellites help power grid keep its balance
Imagine a generator pumping more electricity than a nuclear power plant into the grid, but inconsistently and without the grid's caretakers being able to see what it was doing. How could they maintain the ...
Green conversion of heat to electricity
Soon, it will be possible to produce electricity from heat over 30 degrees emitted from a waste incinerator, refinery, or data processor. The start-up Osmoblue has just confirmed the feasibility of this new ...
