Synergy eyes system security as work begins on Australian big battery
Construction has commenced on what will be Western Australia’s biggest battery energy storage system. The first of the battery units installed for the 100 MW/200 MWh Kwinana Big Battery will be built at the site of the decommissioned Kwinana Power Station near Perth.
Green car dealership powered by renewable
TC Chevy in Ashland, Oregon, is installing pole-mounted solar on trackers manufactured locally by Stracker Solar.
The weekend read: How does the EU taxonomy set criteria for technologies to be labeled green and provide investors with a classification system?
Despite its faults and shortcomings, the EU’s Taxonomy Regulation is expected to support the energy transition and help redirect capital flows to renewables and green assets. Andreas Walstad examines how the taxonomy sets out criteria for technologies to be labeled green and environmentally sustainable in a bid to provide investors with a classification system that boosts clarity, accountability, and predictability.
The Hydrogen Stream: Hyundai to export heavy-duty hydrogen trucks to Germany
Seven German companies have agreed to put 27 Hyundai heavy-duty fuel cell trucks into fleet service in the coming months. American Airlines has revealed an investment in ZeroAvia, while New Fortress Energy has invested in a 120 MW industrial-scale plant in Texas.
Chinese PV Industry Brief: Daqo’s profits soar by 341%
Daqo posted record revenue of CNY 16.3 billion ($2.3 billion) in the first six months of 2022, while Datang Group announced plans to build 5.58 GW of PV plants in China this year.
N-type solar cell with aluminum-titanium passivating contact achieves 21.9% efficiency
Scientists in Australia have demonstrated a new way to apply a passivating contact layer to silicon cells. They produced an n-type cell with aluminum-titanium passivating contact and 21.9% efficiency, and claimed the technique could open up new possibilities for the use of transition metal oxides in cell passivation.
Solar-plus-storage for LED lighting in commercial buildings
Indian researchers claim that commercial buildings with LED lighting could gain energy independence by installing standalone solar-plus-storage systems. They said a 914.4 kW PV system linked to lithium-ion batteries could be enough to power an entire building with an estimated annual demand of 190,830.7 kWh.
High-performance aqueous calcium-ion battery
Researchers from Rensselaer Polytechnic Institute in the United States have developed a special class of materials for bulky calcium ions, providing pathways for their facile insertion into battery electrodes.
Improving gettering tech for TOPCon solar cells
Scientists in Australia have looked at how gettering technologies could improve passivating contacts based on polysilicon and silicon monoxide (SiOx) for tunnel oxide passivated contact (TOPCon) solar cells. They found that the gettering strength of the P-doped poly mainly depends on the doping concentration.
Australian solar park could generate hydrogen for less than $2/kg
A new study shows that hydrogen could be produced for as little as AUD 2.85 ($1.98) per kilogram, supporting Frontier Energy’s plans to make green hydrogen from a 500 MW solar project it is developing in Western Australia.
