Energy Storage

A US-German research group has used above-bandgap light to improve ion mobility in ceramic materials used in lithium-ion batteries and fuel cells. It found that the grain boundary conductance of gadolinium-doped cerium oxide, which is a ceramic used as a solid-state electrolyte in fuel cells, can be improved by a factor of approximately 3.5 at 250 degrees Celsius, by applying the proposed light technique.

Analyst Wood Mackenzie has predicted soaring demand for electric vehicle devices will ensure supply will not keep pace with demand until some point in 2023.

The first Model Y electric cars have rolled off the assembly line at the US electric car manufacturer’s first European factory.

Following the early success of its solar integrated Gannawarra Energy Storage System, Edify Energy has again opted for Tesla Megapack as its preferred battery energy storage system for its combination of storage projects totalling 150MW/300MWh in the Australian state of New South Wales.

Elsewhere, the Fraunhofer ISE research institute has unveiled a new tool for high-resolution power-to-X kinetic analysis, and German entities have signed partnership agreements with the Abu Dhabi National Oil Company.

Scientists in Germany have identified the main challenges that are preventing aqueous zinc-ion batteries (ZIBs) from becoming a mainstream storage technology for power grid applications. According to their analysis, the two main hurdles that must be overcome in future research are the increase of the specific energy of the full Zn-ion cell and the prevention of the parasitic hydrogen evolution reaction occurring during the Zn electrodeposition step.

Australian redox flow battery manufacturer Redflow’s push into the United States market has received a major boost with the company announcing it will work with California-based biowaste technology firm Anaergia on the installation of a solar and 5.5-6MWh battery energy storage solution.

Previously announced plans by the solar developer to pay a deposit to secure gas from a connected business expired on Friday and the company has now said it will focus on a form of the energy carrier powered by renewables.

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-meter facility is being constructed 30 meters below ground and will begin storing green hydrogen next year.

A Dutch-Danish research group has provided a proof of concept for the use of Blatter radicals in electrochemical energy-storage applications. It tested these compounds in a small electrochemical cell that was found to remain stable over 275 charge/discharge cycles.
