Energy Storage

Scientists in the U.S. discovered a promising new battery chemistry based on chlorine and table salt. Batteries based on this chemistry can achieve at least six times the energy density of today’s lithium-ion batteries, according to the group that created it. The prototype battery could already be suitable for small devices such as hearing aids, and with further work could be scaled up to larger applications.

Canadian clean energy company Amp Energy has secured a lease agreement with Indigenous landowners to develop a solar farm and storage system in Whyalla, South Australia. The project is one of three sites which make up the company’s proposed Renewable Energy Hub of South Australia, announced in May.

Australia’s solar uptake is now forecast to reach 8.9 GW by 2025, on top of the 14 GW already installed, according to the Australian Electricity Market Operator.

Genex Power’s latest annual report makes inspiring reading, with its plans for repurposing of the Kidston Gold Mine into a renewable energy hub progressing through stages. Its Jemalong solar farm is also delivering to plan — what then of the write down?

California-based Sakuú Corp. has started work on a 2.5 MWh per year pilot facility to produce 3D-printed solid-state battery tech.

Lithium-ion batteries remain the front-runner to power EVs, but without clearer recycling plans from the European Union and the United States, the balance isn’t yet tipped away from heavy mining of new materials to focus on supplying industry needs, writes Ian Morse.

Researchers at Melbourne’s Monash University have used lessons learned during the development of a solar PV powered microgrid at its Clayton campus to produce an interactive ‘toolbox’ designed to support the uptake of the technology in commercial, industrial and community settings.

Energy Vault secured US$100 million (AU$137 million) in Series C funding for its EVx tower, which stores gravitational potential energy for grid dispatch.

The world’s biggest solar PV and storage project is set to get even larger with the Singapore-based Sun Cable announcing it plans to increase the renewable energy generation and storage capacity of the $26 billion Australia-ASEAN Power Link being developed in northern Australia.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.
