Why 25-cent electricity makes off-grid solar-plus-storage a smart investment in US
Once electricity prices hit $0.25/kWh, disconnecting from the grid with residential solar-plus-storage starts to become financially viable, with sunny places making strong financial arguments. Recent drops in battery prices make the case for leaving the grid even stronger.
UCB to deploy sodium-ion batteries for remote Amazon community
The project involves 48 V sodium batteries, each capable of storing the equivalent of 38.4 kWh. The stored energy will power a school, health center, and community leisure areas for around 30 families. UCB will produce the batteries in Brazil's Manaus Free Trade Zone.

Offgrid PV-driven hydrogen vs. standalone solar-plus-storage
A German research team has compared the economic performance of an offgrid PV-electrolyser-fuel cell system with that of a standalone solar-plus-storage counterpart in a building in Niger. Its analysis showed that decentralized PV-driven hydrogen could achieve considerable lower levelized cost of energy and levelized cost of storage than the PV-battery system, with these values reaching €0.12 ($13.1)/kWh and €0.35/kWh, respectively.
Battery storage secures energy for remote Australian community
An 8.5 kW rooftop solar array and 21 kWh battery energy storage solution have been installed on the remote Australian Northern Territory Mumathumburru, or West Island, providing energy security to a community of people disrupted by unreliable, expensive power since 2021.
India can leverage its solar and storage edge to avoid power shortages
Large-scale solar-plus-storage is the main option left to avoid power shortages as such systems can be deployed much faster than new thermal and hydro assets. Recent gigawatt-scale solar-plus-storage auction results, with a record low price of INR 3.40 ($0.04)/kWh, show that such deployment will be highly economical, according to a new study from the University of California’s India Energy and Climate Center.
