World’s largest hydrogen airplane makes first flight
The hydrogen stream: ZeroAvia tested its new 19-seat hydrogen-powered aircraft, Chinese scientists unveiled new tech to promote bubble removal in electrolysers, and Egypt-Japan University of Science and Technology researchers claimed that the most efficient hydrogen production systems are based on waste heat.
China mulling restrictions on polysilicon, wafer exports
The Chinese government is considering the introduction of export restrictions on solar wafers, black silicon, and silicon casting equipment. It has launched a public consultation process on the proposed measures.
Weekend read: Shining a light on supply chains
The drivers for PV supply-chain traceability could rub against a solar industry enjoying a true seller’s market, with demand outstripping supply. However, supply-chain auditing services are gaining support in increasingly regulated environments. pv magazine’s Tristan Rayner has spoken to a number of auditing experts about how they shine a light on often-opaque operations.
Storing renewables via regenerative braking in underground mines
Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.
New method to measure energy yield of bifacial PV systems
Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.
Weekend Read: Deploying a gigawatt scale mindset
pv magazine Australia’s Natalie Filatoff reports on the benefits of planning vast solar project pipelines, and the barriers faced by those who dare to dream big.
Nextracker to go public
Singapore-based electronics giant Flex announced that its subsidiary, Nextracker, has publicly filed a registration statement for an initial public offering.
New modular solar solution counts on ‘slide-together’ system to cut costs
Aspiring modular solar array manufacturer Green Energy Systems has unveiled a new Australian-made prefabricated modular PV solution for large-scale applications that it says offers significant cost reductions by eliminating all stainless-steel nuts, bolts and other traditional fitments in favour of a slide-together aluminium junction system.
Longi plans new 100 GW wafer plant, 50 GW solar cell factory in China
Longi Solar said it will invest CNY 42.5 billion ($9.4 billion) in 100 GW of wafer capacity and 50 GW of solar cell capacity in Shaanxi province, China.
Hoymiles reveals microinverters for high-power PV modules
Chinese manufacturer Hoymiles has developed a new line of microinverters with up to 96.7% efficiency and outputs of up to 2,000 VA. It said they can be connected with up to four high-power solar modules.
