Korean bank backs Guam’s largest solar project
The Export-Import Bank of Korea is investing in a 132 MW solar plus 325 MWh battery energy storage project in Guam, under development by a consortium of Korean developers.
PV redox flow battery with 4.2% solar-to-electricity conversion efficiency
Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one sun, the device achieved an average solar-to-electricity conversion efficiency of 4.2%.
New York Power Authority renewables plan shows financial challenges for building solar
The levelized cost of building a solar project in New York far exceeds the expected revenue from selling solar power, says a NYPA plan, with project success potentially depending on the sale of renewable energy credits at a satisfactory price.
Solar and storage program forecast to save all Massachusetts ratepayers $313 million per year
Solar plus storage can also offer winter reliability improvements and limit gas consumption, finds a report from Synapse Energy Economics and the Solar Energy Industries Association.
Carmaker uses repurposed EV batteries to help power production plant
Repurposed electric vehicle batteries have been used for the energy storage component of a solar and battery project that is now helping power operations at carmaker Nissan Australia’s aluminium casting plant in Victoria.
Researchers find sodium-ion batteries using hard carbon anodes can intrinsically charge faster
Researchers at Tokyo University of Science showed that sodium-ion batteries with hard carbon anodes can charge faster than lithium-ion batteries by using a diluted electrode method that reveals sodium insertion is intrinsically quicker than lithium.
Solar, wind and storage: stable prices, stable grid
In its latest monthly column for pv magazine, the International Solar Energy Society (ISES) explains how Australia’s rapid expansion of solar and wind energy has not increased wholesale electricity prices, which have remained stable since 2016. Rooftop solar, now widespread and highly cost-effective, provides the country with resilient, low-emission power, making all-electric homes increasingly independent from the grid.
Ambrion launches new all-in-one storage solutions
The Australian firm has introduced single-phase 5 kW and 6 kW AC output storage systems, as well as three-phase 10 kW and 12 kW models. Storage capacities of the new products range from 5 kWh to 40 kWh.
Canon testing solar at Japanese data center
Canon IT Solutions has begun testing a solar PV system to power its Tier 4 data center in Nishitokyo, aiming to boost renewable energy use and reduce costs. The system is expected to generate around 69 MWh annually and enhance power resilience during emergencies.
Greek solar producers petition EU over repowering and storage rules
Two complaints to the European Commission allege Greek repowering policies and high performance bonds for battery storage projects block upgrades, raise costs, and hinder energy transition, according to industry association Pospief.
