Salzstrom is an Austrian clean tech company that develops and sells innovative, safe, and sustainable energy storage systems based on sodium-ion battery technology. The startup targets residential, commercial, and industrial markets with hardware that eliminates the need for critical resources like lithium, cobalt, and nickel. Crucially, the company was among the first to bring a CE-certified sodium-ion home storage system to the European market. Salzstrom secured a seven-figure pre-seed funding round in April 2025 to scale its operations.
