Scientists in the United States developed a computer simulator that can calculate the conversion efficiency of different solar cell materials and configurations – helping to guide research and optimisation of new cell designs. The simulator is available to researchers as an open-source tool to save time and spot the best opportunities for optimisation of any given approach.

The hype surrounding green hydrogen is real, but does the cost-reduction outlook for its production technologies live up to it? Christian Roselund looks at the technology, transportation, application and enabling policies behind the promising green energy carrier.

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

Large-scale renewable energy generators, including wind and solar PV farms will ramp up to 140 GW from the current 15 GW, more than doubling every decade to 2050 while rooftop solar is expected to increase from 15 GW to 70 GW over the same period as the “accelerating” transformation of Australia’s energy sector continues.

The impression of another big battery being installed on the site of one of Australia’s recently decommissioned “coal clunkers” was lost on few. Battery system provider Fluence says the Hazelwood Battery Energy Storage System’s business case was bolstered by recent reforms and new technology to take advantage of rapidly changing wholesale electricity market dynamics.

Scientists have developed a new model based on fault tree analysis to evaluate the frequency of fires caused by rooftop PV systems and assess system safety and reliability. They claim that the new tool has the potential to identify fault linkages in systems, highlight failure patterns before they arise, and compare multiple designs for safety.

A consortium including Australian concentrated solar thermal power company Vast Solar has filed to patent a new tank design for thermal energy storage systems. The new design, it says, substantially mitigates the risk of tank failures which have been identified as one of the key shortcomings of the economical storage technology.

Australian hydrogen research and development company, Star Scientific, has announced its technology will be used to provide heat for industrial-scale sanitation in a pilot with Mars Food Australia.

Sydney-based solar pioneer 5B has today announced it will acquire IXL Solar’s Adelaide-based manufacturing business, with pv magazine Australia told the purchase will see 5B buy everything but the name, effective immediately.

Floating PV is a growing niche in the solar sector, but its offshore segment has proven more difficult to activate, largely because of the difficulty of open-water energy generation. Nevertheless, the potential of offshore floating PV is almost unlimited, and one Singaporean firm, G8 Subsea, is looking to leave the safety of harbours and reservoirs.
