About Azelio

Azelio is a Swedish startup that has carved a niche in the Renewable Energy sector with its innovative thermal energy storage solution. Founded in 2008, the company addresses a growing demand for sustainable and cost-effective energy alternatives.

Azelio's technology offers a storage capacity of 13 hours at nominal power and is designed to be scalable, making it suitable for installations ranging from 0.5 to 20 MW—expandable to 100kW up to 100 MW. This provides a competitive edge, especially in the microgrid segment where cost-effective and sustainable solutions are sparse.

The company's adaptable system can integrate into various applications, serving as a load shift tool, a distributed baseload option, or an off-grid solar system compatible with long-duration energy storage. Notably, Azelio's last known financing was a Venture investment of the Series Unknown on 07 November 2018. This marks a period of investment retention, indicating prudent financial management and a possible need for fresh capital to expand market reach.
