Technology and R&D

Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.

Commissioning of one of Australia’s first solar-powered utility scale vanadium flow batteries has commenced with developer Yadlamalka Energy confirming that construction of its $22 million Spencer Energy Project in South Australia is now complete.

Critical energy minerals company Vecco Group has celebrated the official opening of Australia’s first commercial-scale vanadium battery electrolyte manufacturing facility in Townsville by announcing it has secured a contract to provide Energy Queensland with the state’s first grid-scale vanadium flow battery.

The research group led by Professor Martin Green has published Version 62 of the solar cell efficiency tables. There are 21 new results reported in the new version, a record number for the Tables.

The International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) has published a report to help the solar industry to choose appropriate surface radiation models and data providers based on location and application requirements.

Scientists in Belgium are exploring the potential of recycled silicon in solar modules at the end of their life cycle for reuse in low-cost, higher-energy-density storage technologies. They claim EV batteries using this silicon may allow faster recharging and travel longer distances on a single charge.

China’s Bslbatt says its new batteries have 10.24 kWh of storage capacity and a nominal voltage of 51.2 V. It measures 700 mm x 980 mm and is 100 mm thick.

Sydney company Key Energy has installed a three-phase flywheel energy storage system at a residence east of Perth, WA. The 8 kW / 32 kWh system was installed over two days in an above-ground enclosure, dramatically cutting the time needed to install the flywheel system.

Canadian Solar is offering six versions of its 132-cell TOPBiHiKu7 solar modules, with power outputs ranging from 675 W to 700 W and efficiencies ranging from 21.7% to 22.5%. They have an efficiency range of 26.1% to 27.0%, with a bifacial gain of 20%.

SolarEdge’s new bidirectional DC-coupled electric-vehicle (EV) charger enables vehicle-to-home and vehicle-to-grid applications and can seamlessly integrate with its home energy systems. It is scheduled for release in the second half of 2024.
