China’s polysilicon imports fell by 23% in 2022, says Bernreuter Research

After an interim high in 2021, polysilicon imports into China fell again in 2022, but the country’s share in global output still came close to 90%, according to a new report by Bernreuter Research.


High-capacity energy storage based on affordable, eco-friendly materials

Worldwide Universities Network researchers used cheap and abundant starting materials to synthesize a small molecule organic electrode material and achieved a considerable performance boost with various battery chemistries. The new cathode material exhibited unparalleled cycling stability, ultra-high capacity, and rate capability in aqueous zinc-ion batteries.

BayWa re unit completes floating PV plant in Austria

BayWa re’s ECOwind subsidiary and Austrian energy supplier EVN have finished building a 24.5 MWp floating PV plant in Grafenwörth, Austria. They claim it is the biggest such installation in Central Europe.


Aggreko releases new line of modular, mobile battery energy storage solutions

Aggreko, a UK-based mobile power and cooling solutions supplier, has released a new line of 30 kVA and 60 kVA battery storage modules. The fully integrated systems are developed for commercial and industrial energy storage applications.

Custom-made 3D printed solid-state batteries

US-based Sakuu has announced that it has successfully 3D printed solid-state batteries in custom shapes and sizes at its battery pilot line facility in Silicon Valley, California.

UK power capacity auction delivers 627 MW of battery storage

Britain’s T-1 Capacity Auction for delivery in the 2023-24 period saw battery energy storage technology emerge as the third-biggest winner in terms of secured contracts, following gas and nuclear. Batteries accounted for more than a half of the new build capacity.


Iron-chromium flow battery for renewables storage

Researchers in China have successfully prepared cobalt oxide-modified graphite felt as an electrode material for an iron-chromium flow battery. The electrode performance significantly improved due to the effects of cobalt, which in turn boosted the energy efficiency and overall performance of the battery.

How safe are second-life EV batteries as home energy storage devices?

There is currently no widely accepted test methodology to assess the safety of second-life lithium-ion batteries (LiBs). However, a UK government study reveals two opposing views on their safety, raising concerns over whether such devices should be deployed in homes under any circumstances.


Integration of EV charging stations and renewable energy resources

A new research paper proposes an optimal planning technique to identify the locations and sizes of electric-vehicle (EV) charging stations with controlled charging and hybrid wind and PV systems in a multi-microgrid.


Weekend Read: Dawn of the store-age

Last year was another landmark 12 months for energy storage, with all indicators pointing to a massive surge in demand. Supply chain instability and inflation saw battery prices rise but the industry demonstrated an ability to swiftly react to geopolitical developments. We look at five trends driving the market.
