25-Year Fireproof Home Battery: Sodium-Ion Arrives!
17 views1:52
A revolutionary home battery is hitting the European market, promising 25 years of fire-free energy storage. Unigrid's Nekasa sodium-ion system offers a safer, more sustainable alternative to traditional lithium-ion batteries, relying on abundant salt instead of scarce minerals. This marks a significant shift in home power solutions.
This modular system stores 10-30 kWh, is non-flammable, and operates reliably in extreme conditions, backed by a 25-year warranty and 6,000 cycles. Industry analysts predict a massive market growth for sodium-ion, seeing it as a game changer for stationary home storage due to its safety and cost advantages, with US rollout planned for 2026.

A home battery that lasts 25 years without catching fire is now hitting the European market, and a US rollout is already in the works. Unigrid has launched the Nekasa sodium-ion battery system, offering homeowners a safer, more sustainable alternative to lithium-ion, one that relies on abundant materials like salt instead of scarce minerals. The modular system stores 10 to 30 kilowatt hours, is non-flammable, and operates reliably in extreme heat and cold. With over 6,000 cycles at 80% depth of discharge, the 25-year warranty could drastically cut replacement costs. Industry analysts see a massive shift coming. The global sodium-ion battery market is projected to grow from $1.9 billion in 2025 to over $13 billion by 2035. While energy density lags behind lithium, experts say that for stationary home storage, safety and cost advantages make sodium-ion a game changer, especially as geopolitical chaos strains centralized energy grids. Unigrid's debut marks a commercial milestone as sodium-ion moves from labs into living rooms, targeting solar users and off-grid homeowners. Even major players like CATL have unveiled 20-year sodium-ion batteries, signaling industry-wide commitment. The Nekasa is now available in select European markets, with US installations expected in 2026, pending regulatory approval. For homeowners ...
