Russian design for vanadium redox flow batteries
Researchers claim to have developed a cheaper, faster method of assembling the field flow plate layers of the membrane electrode assembly used in vanadium redox flow batteries, which they claim outperforms traditional components.
New business model to help utilities own and operate rooftop PV
Scientists from the Lawrence Berkeley National Laboratory in the U.S. have defined a utility-ownership model for rooftop PV they say could raise power company shareholder earnings 2-5%.
Modi loosens the purse strings to help India’s struggling state utilities
Covid-19 hits to demand and bill payment collection have worsened the plight of the nation’s already debt-crippled power distribution companies, prompting the government to order an exceptional relaxation of lending limits.
Consolidation continues for polysilicon makers
While mono-grade polysilicon prices did not decrease much in the first quarter owing to stable demand, multi-grade fell to record lows as its market share diminished. During the second quarter, writes PV InfoLink senior analyst Cooper Chen, the market saw excessive supply. Monocrystalline manufacturers have been running at full tilt and bringing new capacities online as scheduled, while the pandemic rages on overseas.
Strategies to improve rechargeable zinc metal batteries
A lack of standardized protocols is preventing rechargeable zinc metal batteries from complementing lithium-ion storage tech. A U.S. research team is now calling for standardized protocols for columbic efficiencies and greater zinc/electrolyte stability to make the technology viable.
World’s largest battery storage system now operational
It’s a title that is becoming more contentious by the day, but for the time being, LS Power’s 250 MW Gateway project in San Diego, California, is the biggest storage battery in the world.
Airlifting PV modules for C&I solar projects
Is airlifting solar modules the future of commercial and industrial rooftop PV installation? Epho Commercial Solar recently used a helicopter to airlift pallets of modules to 12 rooftops at a Woolworths location in Australia.
New 635-660 W module series from Trina
The latest products in the Vertex series from the Chinese manufacturer, unveiled at the SNEC PV Power Expo in Shanghai, are available in six versions with reported efficiency ranging from 20.4-21.2%.
A battery chemistry schism is imminent
A report from Wood Mackenzie predicts lithium-iron-phosphate will overtake lithium-manganese-cobalt-oxide as the dominant stationary energy storage chemistry within the decade.
Covid-19 weekly round-up: Differing opinions on energy storage fall-out, a trade show update and some surprisingly positive financials
Negative second-quarter updates from China and uber-low new-solar figures from India, however, show the world is far from out of the woods yet.
