Battery storage

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 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.

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 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.

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.

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 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.

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.

Welsh battery breakthrough uses UK-manufactured anode and cathode materials as well as active materials available through local supply chains. Batri plans to scale up material manufacturing and cell building capability.

The Indian manufacturer said its new Geon Gelithium series is an efficient back-up solution for homes, clinics, small retail outlets, offices, and light commercial applications. The system is available in two versions with an inverter rated capacity of 1,250 VA and 2,500 VA, respectively.
