Silicon Valley-based start-up Gridtential has secured US$12 million (AU$15.5m) in funds to develop what it calls the world’s first factory-ready, single-block, 24V, deep-cycle lead battery. The product is claimed to be ideal for personal mobility vehicles and renewable energy storage in homes and offices.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

New cell and module technologies are boosting power outputs, but they often have implications for quality. A focus purely on cell cracking illustrates just this point, with some approaches proving beneficial, and others potentially problematic – cue Tristan Erion-Lorico from PV Evolution Labs (PVEL).

The solar industry in Europe and the United States is continuing to ramp up the pressure on the use of polysilicon produced in Xinjiang, China – in response to allegations that forced labour is being used in its production. By contrast, the Australian industry’s response has been markedly muted. Although it is true that most global solar industries are heavily reliant on Chinese manufacturing, Australia is overwhelmingly so.


The Chinese manufacturer will begin selling its new products in Australia and Europe. The hybrid inverter has an efficiency of up to 98.4% and the lithium iron phosphate battery features a storage capacity between 9.6 kWh and 102.4 kWh, depending on the number of modules.

Scientists in the UK used the latest imaging techniques to visualize and understand the process of dendrite formation and electrolyte cracking in an all solid-state battery. With new insight into the mechanisms by which these cracks form and ultimately lead to battery failure, the results could help direct the focus of future research into solid-state battery technology.

Australian peak body, the Smart Energy Council, has this morning revealed the details of the initial global and domestic partners for its hydrogen Zero Carbon Certification Scheme. The scheme seeks to provide a guarantee of origin for hydrogen, ammonia and other derivative products like steel, in preparation of Australia becoming a global hydrogen export hub.

Researchers in Germany claim to have overcome the primary hurdle in the development of large-area perovskite PV modules – scaling up from the cell to the module level. They achieved an efficiency of up to 16.6% on a module surface of ​​more than 50 centimetres squared, and 18% on a module with an area of 4 centimetres squared.

In an earnings call, the company said that storage deployments grew 71% YoY and solar installations were its strongest in 2.5 years.

The two new products will be part of the Hi-MO4m panel series for rooftop applications. Their efficiency ranges from 19.2% to 21.2%.
