Jupiter Power has secured $1.4 billion in financing to support 10 US battery energy storage system projects totaling 3,600 megawatt-hours (MWh) of capacity, with individual projects ranging from 360-1,200 MWh each.

China's electric grid releases vast quantities of the world's most potent greenhouse gas, known as sulfur hexafluoride (SF6), which is a climate super-pollutant cooking the planet. Recycling efforts could slash emissions at little cost, according to an analysis by Inside Climate News. SF6 has no natural sources and is released mainly from China's high-voltage power transmission equipment.

Nova Scotia is planning a massive offshore wind project that could provide clean power to the US, contradicting Trump's efforts to reduce renewable energy in Canada. The project exceeds the province's electricity demand and has significant implications for access to clean power in the region. It could also serve as a counterpoint to Trump's "America First" energy policy.

Brazil imported 5.48 GW of PV modules in the first half of 2026, down 48% from 10.57 GW in the same period of 2025, due to a sharp slowdown in demand for PV equipment, particularly from utility-scale projects. The contraction was driven by curtailment, which reduced projected project revenue and increased perceived risk for new investment. Module imports declined in nearly every month of the six-month period, with only May seeing an increase.

A 144 Tesla Megapack system powers Australia's first 8-hour grid battery, called the Limondale battery in New South Wales, which can discharge for a full eight hours. This is four times longer than typical two-hour batteries on the Australian grid. The project marks the country's first of its kind.

Chinese battery manufacturer EVE Energy has signed a framework agreement with U.S.-based energy storage supplier Fluence to deliver up to 206 GWh of batteries between 2027 and 2031. The deal covers a committed delivery volume of 16 GWh for 2027, with an additional 190 GWh reserved for the following years. Specific product details will be determined through subsequent purchase orders, but changes in industry policy or market conditions may impact implementation.

Researchers at Nanyang Technological University have developed an artificial leaf that uses solar energy to produce hydrogen from contaminated seawater via electrolysis, while also degrading toxic hydrazine contaminants. The device features a perovskite cathode and an anode with a catalyst that breaks down hydrazine into hydrogen and nitrogen. The invention has been shown to generate hydrogen at a rate comparable to similar solar-powered devices for over 72 hours under sunlight equivalent to the Earth's surface on a clear day.

Anker's SOLIX E10 Whole-Home Backup System is on sale starting from $3,799, while a Heybike ALPHA mid-drive e-bike can be purchased at its lowest price of $1,099. Additionally, the EcoFlow 3072Wh DELTA 3 Ultra Plus Power Station with a 500W solar panel is available for $1,899, and other deals include robot mowers and smart home devices.

Microsoft is preparing to appeal a decision by the Virginia State Corporation Commission regarding direct assignment of transmission costs, which could impact its ability to challenge data center transmission costs. The company has until November to formally submit its appeal. Dominion Energy must also propose compliant policy changes by October.

China has commissioned a 600 MW compressed-air demonstration project, and Hydrostor has developed a large-scale compressed-gas storage system. These developments demonstrate the potential of compressed-gas electricity storage, but also highlight the ongoing challenges with economics. The sector's growth does not seem to be driven by improvements in economic viability.
