Professor models system using baking soda filled capsules to capture CO2 emis...
12 Dec 2018 at 10:44am
Coal and natural gas represent the majority of the US energy supply. Even with pollution controls, burning these fossil fuels for energy releases a tremendous amount of carbon dioxide into the atmosphere. Research uses microcapsule technology that may make post-combustion carbon capture cheaper, safer, and more efficient.
Low-cost catalyst boosts hydrogen production from water
12 Dec 2018 at 9:18am
A future powered by carbon-free fuel depends on our ability to harness and store energy from renewable but intermittent sources, such as solar and wind. Now, a new catalyst gives a boost to a number of clean energy technologies that depend on producing hydrogen from water.
How will the winds of climate change affect migratory birds?
10 Dec 2018 at 12:18pm
Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.
Fighting smog supports solar power
6 Dec 2018 at 8:59am
Model calculations by researchers show that if China fought smog more aggressively, it could massively increase solar power production.
'Sun in a box' would store renewable energy for the grid
5 Dec 2018 at 2:19pm
Engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a small city not just when the sun is up or the wind is high, but around the clock.
Fine-tuning renewables could help Texas balance energy resources
5 Dec 2018 at 11:27am
A new study analyzes Texas' mix of wind and solar energy resources, and how to achieve better balance between them going forward.
Wind power vulnerable to climate change in India
5 Dec 2018 at 11:27am
The warming of the Indian Ocean, caused by global climate change, may be causing a slow decline in wind power potential in India, according to a new study.
Global carbon dioxide emissions rise even as coal wanes and renewables boom
5 Dec 2018 at 10:39am
Renewable energy capacity has hit record levels and global coal use may have already peaked. But the world's carbon dioxide emissions from fossil fuels increased in 2018, and the trend places global warming targets in jeopardy.
Brilliant iron molecule could provide cheaper solar energy
30 Nov 2018 at 8:16am
For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.
New catalyst produces cheap hydrogen fuel
29 Nov 2018 at 7:00am
Chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.
Coordinated development could help wind farms be better neighbors
26 Nov 2018 at 10:43am
New research highlights a previously underexplored consequence: A wake effect from upwind wind farms that can reduce the energy production of their downwind neighbors.
Explaining the plummeting cost of solar power
20 Nov 2018 at 4:38am
The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop? A new analysis has pinpointed what caused the savings, including the policies and technology changes that mattered most.
Renewable energy cooperatives, an opportunity for energy transition
12 Nov 2018 at 10:15am
Researchers have explored how renewable energy cooperatives have evolved. They have found that these cooperatives have developed a significant capacity to survive and adapt in response to the hostile context brought about by the economic and political regime.
Making wind farms more efficient
9 Nov 2018 at 9:26am
With energy demands rising, researchers have completed an algorithm -- or approach -- to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their customers.
Solar power: largest study to date discovers 25 percent power loss across UK
9 Nov 2018 at 7:14am
Regional 'hot spots' account for the power slump and these are more prevalent in the North of England than in the south.
