Sthyr Energy Secures Funding for Long-Duration Energy Storage
Sthyr Energy, a company that came from IIT Madras, got $1 million to build a better way to store energy.
They're making special batteries that can store clean energy for a long time, like storing the sun's energy in the summer to use in the winter.
These batteries use safe materials and can replace old-fashioned power plants.
The money will help them test their batteries and work with other companies.
The goal is to make it easier to use clean energy everywhere and provide reliable backup power.
Sthyr Energy, an IIT Madras-incubated startup, secured $1 million in seed funding.
The funding round was led by Speciale Invest, with participation from Antares Ventures.
The company is developing a long-duration energy storage system using Zinc-Air battery technology.
The technology aims to store clean energy for extended periods and replace fossil fuel plants.
Sthyr Energy plans to use the funding for R&D, pilot systems, and partnerships.
