Engineered bacteria could be missing link in energy storage
23 May 2019 at 10:02am
One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution.
Producing electricity at estuaries using light and osmosis
23 May 2019 at 8:13am
Researchers are working on a technology to exploit osmotic energy -- a source of power that's naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production.
Key insight into solar material's soaring efficiency
23 May 2019 at 6:13am
Researchers have reported a key breakthrough in how the performance of cadmium telluride thin-film solar cells is improved even further by the addition of another material, selenium.
Table scraps can be used to reduce reliance on fossil fuels
23 May 2019 at 6:12am
New technology engineers natural fermentation to produce a biodegradable chemical that can be refined as a source of energy.
Artificial photosynthesis transforms carbon dioxide into liquefiable fuels
22 May 2019 at 12:31pm
Chemists have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess carbon dioxide to store solar energy -- in the form of chemical bonds -- for use when the sun is not shining and in times of peak demand.
Water formation on the Moon demonstrated

A new study has shown chemical, physical, and material evidence for water formation on the Moon.
New material could unlock potential for hydrogen powered vehicle revolution
15 May 2019 at 5:54am
An international team of researchers has discovered a new material made from manganese hydride that would be used to make molecular sieves within fuel tanks - which store the hydrogen and work alongside fuel cells in a hydrogen powered 'system'. The material would enable the design of tanks that are far smaller, cheaper, more convenient and energy dense than existing hydrogen fuel technologies, and significantly out-perform battery-powered vehicles.
Breakthrough in new material to harness solar power
14 May 2019 at 5:15am
Physicists are pushing the performance of solar cells to levels never before reached. They have made a significant breakthrough in the chemical formula and process to make a new material. The ultra-high efficiency material called a tandem perovskite solar cell is being developed to help solve the world energy crisis.
A step for a promising new battery to store clean energy
13 May 2019 at 12:56pm
Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation's power grid and longer-lasting batteries in cell phones and laptops.

Advancements in zero-emission fuel cells could make the technology cheap enough to replace traditional gasoline engines in vehicles.
Experimental device generates electricity from the coldness of the universe
6 May 2019 at 1:36pm
A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work looks to provide a potential path to generating electricity like solar cells but that can power electronics at night.
Public dread of nuclear power limits its use
6 May 2019 at 1:07pm
Nuclear power has been a part of the American energy portfolio since the 1950s, but for a number of reasons, the general public has long felt a significant dread about it.
