STEGS™
STEGS™: Redefining Dispatchable Renewable Power
The Solar Thermal Energy Generation and Storage (STEGS™) system is EVMG’s flagship innovation—an advanced, patented solution to one of renewable energy’s most persistent challenges: intermittency.
STEGS™ captures heat in a proprietary thermal storage block engineered for maximum heat retention. The stored energy is then released in a controlled manner through a turbine generator to produce electricity.
What Sets STEGS™ Apart
Unlike solar PV, batteries, or CSP systems, STEGS™ delivers true utility-scale, dispatchable energy with an exceptionally long operational lifecycle. STEGS™ is superior in terms of capital cost, cost of generation, and acres used per MW of capacity.
Some key advantages include:
STEGS™ encapsulates
- High thermal storage capacity for consistent long-duration output
- Zero reliance on batteries or water
- Modular scalability, from small solutions to 500+ MW deployments
- Zero emissions
- Efficient use of land per MW of generation
- AI-enhanced design modelling via the proprietary DOVET™ platform
Designed for Global Resilience
Whether constructed in arid deserts, humid coastal areas, or temperate zones, STEGS™ is engineered to thrive in diverse environments. Its low-maintenance design reduces operating and maintenance costs, and environmental impact, making it a compelling alternative to fossil-fuel, nuclear, and PV with battery. The STEGS™ system has the additional advantage of having a long life span compared to PV and other renewables.
From Vision to Validation
STEGS™ is the product of years of engineering evolution, building on the thermodynamic foundations of EnviroMission’s Solar Tower. Now, STEGS™ is on track to become a major technology in the global transition to round-the-clock clean energy.
