Energy Storage Solutions by phelas

We at phelas are developing an electricity storage system to use solar and wind power even when the sun is not shining and the wind is not blowing. Our Aurora Liquid Air Energy Storage (LAES) system is at the heart of this vision, transforming renewable sources into a stable, around-the-clock power supply. Compact, sustainable, and efficient, Aurora is more than just technology; it’s a beacon for a cleaner, renewable future.

Alongside Aurora, Catalyst serves as a decision enabler, guiding energy leaders towards smarter, greener decisions. It’s not just about providing solutions; it’s about providing know-how and empowering a community committed to sustainable energy practices. Together, Aurora and Catalyst aren’t just powering our homes and businesses—they’re powering our collective journey towards a sustainable world.
