Energy Storage

Researchers from Australia’s Monash University have created a new generation of lithium-sulfur batteries that they say provides a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing.

Developed by Germany-based hydrogen specialist Enapter, the EL 4.0 electrolyser is based on a patented anion exchange membrane (AEM) technology. Commercial production is currently being prepared at the company’s Italian plant and the first shipments should be made in the summer.

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.

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.

Long thought of as adversaries to renewable energy, fossil fuel assets and infrastructure also present opportunities for solar, its green-hydrogen output, and smart energy storage. Natalie Filatoff reports on the opportunities and approaches the miners are taking.

Fortescue Future Industries has acquired Williams Advanced Engineering for $310 million as it looks to capitalise on its critical battery technology to cut emissions from its mining vehicles. An offshoot of the Williams Formula 1 Team, Williams Advanced Engineering has already helped to develop an electric mining haul truck for Fortescue in 2021.

Anglo-Australian mining giant Rio Tinto’s ambition to become one of the world’s largest lithium suppliers has taken a battering with the Serbian government pulling the plug on the company’s $3.3 billion ($US2.4 billion) Jadar lithium-borates project.

Current price signals to distributed battery owners “do not align with grid value,” says a study from the Lawrence Berkeley Laboratory.

The investment is planned to support development and construction of Hydrostor’s 1.1GW, 8.7GWh of Advanced Compressed Air Energy Storage projects that are well underway in California and Australia, and help expand Hydrostor’s project development pipeline globally.

Western Australia’s state-owned electricity company Horizon Power has installed 19 solar + battery standalone power systems for farmers in Esperance on the state’s southern coast.
