Energy Storage

Australian company Natural Solar has seen a 400% increase in battery installs across Australia within two years. The company’s CEO Chris Williams told pv magazine Australia that Victoria has led demand, growing 350% in the second half of 2021 alone. Williams believes the surge has been driven by several compounding factors.

Australian concentrated solar thermal power company Vast Solar has been shortlisted as a finalist for BNEF’s Pioneers 2022 program.

Conceived by scientists in China, the battery was built with a special hydrogel electrolyte made of polyacrylamide (PAM), zinc sulfate (ZnSO4), glycerol (GL), and acetonitrile (AN). The device showed high cycling stability of over 3,000 cycles, a high reversibility thanks to a Coulombic efficiency of up to 99.5%, and electrochemical performance of 185 mAh·g over 10,000 cycles.

Chinese manufacturer Bslbatt has unveiled a modular lithium-ion battery that can be used for the off-grid storage of solar energy. The device has a storage capacity ranging from 5.1 to 30.7 kWh and is claimed to provide steady operation for up to 6,000 charge cycles.

Origin Energy’s announcement that it is accelerating the closure of Australia’s largest coal-fired power station has triggered calls for the Federal Government to develop a nationally co-ordinated approach to manage the retirement of fossil fuel generation as well as support investment in new clean energy generation.

The Moss Landing Energy Storage Facility Phase II in the United States set off fire alarms that activated a fault water suppression system, triggering a cascading set of events that resulted in roughly 10 battery packs melting down.

One of Australia’s largest residential and commercial solar PV retailers and installers has announced it will exit the market, declaring low margins and once-in-a-generation disruptions to the supply chain brought on by the Covid-19 pandemic have taken a toll.

Renewable energy investors have again shattered the New South Wales Government’s expectations with more than 80 clean energy projects representing more than $100 billion of potential investment registering for the Hunter-Central Coast Renewable Energy Zone.

Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm2, an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm2. The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than US$100/kWh (AU$140).

A bill which would make home batteries up to $3,000 cheaper nationwide has been tabled by Independent MP Helen Haines. Haines proposes making home batteries eligible for Small-scale Technology Certificates, the same scheme behind Australia’s thriving rooftop solar sector.
