Power Storage in Homes Increases Emission but Storage by Utilities Has Clear Benefits

Written by , on February 7, 2017

Researchers have found that storing solar energy for nighttime use increases a household’s annual energy consumption compared with using solar panels without storage. On the other hand, storage by utility companies significantly reduces the amount of electricity generation capacity required.  Read more »

Storing Solar Energy in Heat Batteries

Written by , on October 24, 2016

Sunamp is storing excess PV energy in a “heat battery” containing the same kind of phase change material used in hand warmers. When hot water is needed, it is passed through the heat battery containing the phase change material. This brings the water up to the required temperature using the energy that would have otherwise gone to waste or been sold to the grid.   Read more »

Engineers at the University of Colorado, Boulder, have developed an innovative bio-manufacturing process that uses a biological organism cultivated in brewery wastewater to create the carbon-based materials needed to make energy storage cells.  Read more »

Battery Charged by Solar Energy

Written by , on September 27, 2016

Scientists at the University of Wisconsin-Madison have developed a single device that uses solar energy to charge a battery without the intermediate step of producing electricity and then using that electricity to charge the battery.  Read more »
