Ultracapacitor sonar seeking grid with 100% solar, wind
Reactive Technologies uses an ultracapacitor to send signals to the grid that help managers determine the level of system inertia, supporting power grid stability – and they’re coming to the United States.
The weekend read: The financial risk of investing in PV systems and the ‘Peter PAN’ files
The financial risk of investing in photovoltaic systems is increasing. This is because the yield forecasts on which profitability audits are based are increasingly too optimistic. One reason for this could be the handling of so-called PAN files, reports pv magazine Deutschland’s Marian Willuhn.
Chinese PV Industry Brief: Longi, Zhonghuan raise wafer prices
A Chinese industry group has reported rising polysilicon prices and supply chain problems ahead, but GCL Technology said this week that strong polysilicon and wafer prices were the reason its business performed strongly in 2021.
The Hydrogen Stream: High-pressure PEMEL electrolyzers for lower hydrogen costs
Elsewhere, Lotte Chemical and Air Liquid Korea will establish a joint venture to build a hydrogen supply chain in South Korea and the US Department’s Loan Programs Office (LPO) offered a conditional commitment for a US$504.4M loan guarantee to the Advanced Clean Energy Storage Project in Utah, which combines alkaline electrolysis with salt cavern storage for grid scale energy conversion and storage using hydrogen as the energy carrier.
Cyprus launches PV, battery funding scheme as Greece turns to gas
Cyprus has launched a new scheme to fund installations of PV arrays and battery systems, with a specific focus on owners of electric vehicles. Greece, meanwhile, has devised a subsidy scheme to support the use of gas for conventional cars.
EPFL achieves 29.2% efficiency for tandem solar cell with fully textured silicon
Scientists in Switzerland made significant progress with an approach to perovskite-silicon tandem cell design that they say could eventually be integrated into existing silicon PV manufacturing. They have announced the achievement of a 29.2% cell efficiency – not far from the overall record for tandem cells, and verified by Germany’s Fraunhofer ISE.
