Weekend read: BESS lessons learned

Taking a rigorous approach to inspection is crucial across the energy storage supply chain. Chi Zhang and George Touloupas, of Clean Energy Associates, explore common manufacturing defects in battery energy storage systems (BESS) and how quality-assurance regimes can detect them.

Solar-plus-storage outperforms diesel in US military survival analysis

The US Department of Energy’s National Renewable Energy Laboratory (NREL) has determined that Antora Energy’s solar-plus-storage system meets the US military’s stringent standards, as it significantly outperforms emergency diesel generators in survivability probabilities.

Novel algorithm estimates global maximum power point in partially shaded PV systems

Developed by scientists in India, the global maximum power point (GMPP) technique is based on the voltage and current of strings in a PV array. The research group tested it in computer simulation, as well as through an experimental setup.

Australian researchers delve into lithium microstructures causing catastrophic battery failures

Researchers from the Australian Nuclear Science and Technology Organisation (ANSTO) have used advanced neutron scattering techniques to better understand what leads to catastrophic failures in lithium ion batteries.

Queensland Bouldercombe battery fire ignited on grid side, not within Megapack, analysis finds

Genex Power, owner of the 50 MW / 100 MWh Bouldercombe battery which caught fire in Queensland on September 26, says its preliminary root cause analysis found the fault occurred at the grid side of the Tesla Megapack battery unit.

New research suggests renewables may not necessarily foster democracy, peace

Researchers in Germany have found that there is “no evidence” to support the notion that renewable energy generation fosters peace through prosperity. The trio of academics came to this conclusion after empirically testing the assumption that distributed renewable energies may reduce international conflicts and promote democratic values.

New survey shows ‘massive’ increase in PV module microcracks

A new study from Clean Energy Associates (CEA) shows that 83% of sites tested as part of a global survey had line cracks, 78% had a soldering anomaly and 76% had complex cracks. The survey involved visual inspections combined with electroluminescence testing across 148 sites in 16 countries.

Strategies to develop ‘solar neighborhoods’

Researchers from the Australian PV Institute are part of an international group of scientists that have devised a list of recommendations to support the creation of solar neighborhoods. In a recently published study they highlight the importance of legislative frameworks and advanced computing.

Belgians beat wind to claim World Solar Challenge

Belgian Solar Team Innoptus has claimed back-to-back Bridgestone World Solar Challenge titles, beating home dozens of competitors from around the world to win the 3,000 kilometre race through Australia’s outback.
