In a marked departure from years of cautious optimism, merchant battery energy storage systems (BESS) in India have turned profitable. According to a new report from energy think tank Ember, BESS projects commissioned in 2025 could deliver internal rates of return (IRR) of up to 17% by engaging solely in India’s power exchanges—without fixed power purchase agreements (PPAs).

Sulphate Salts May Hold Key to Scaling Aqueous Battery Lifespan for Grid-Scale Storage

As the global market for aqueous batteries accelerates—projected to exceed $10 billion by 2030—a new study from KAUST’s Center of Excellence for Renewable Energy and Storage Technologies (CREST) sheds light on a persistent challenge: short lifespan due to parasitic reactions at the metal-electrolyte interface. The research, published in Science Advances, reveals that the addition of sulphate ions, specifically from salts like zinc sulphate, could increase aqueous battery lifespan by over a factor of ten, while maintaining chemical stability and cost-effectiveness. The finding has implications well beyond academic interest. Aqueous batteries are positioned as safer, more sustainable alternatives to lithium-ion systems…

Electricity

As the world navigates a complex energy landscape in 2025, global electricity demand is poised for significant growth, anticipated to increase by 3.3% in 2025 and 3.7% in 2026. These figures represent some of the most accelerated growth rates witnessed in over a decade, driven by persistent industrial demand, advancements in electrification, expanding air conditioning usage, and the burgeoning requirements of data centers. However, this growth does not come without its challenges. Global CO2 emissions from electricity generation are showing signs of plateauing. Following a modest growth of 1.2% in emissions in 2024, 2025 is expected to see little change,…
