FAQ
STEGS™ employs Thermal Energy Storage (TES) blocks that capture and retain heat at high temperatures. This stored heat is then converted into electricity on demand, allowing STEGS™ to operate as a true baseload renewable system. The TES design ensures durability, scalability, and cost-efficiency, with long asset lifespans and low degradation compared to batteries.
The stored thermal energy is used to drive conventional power generation systems, such as turbines, to produce electricity. This use of well-established industrial processes ensures reliability, reduces technical risk, and supports seamless integration into existing grid infrastructure.
STEGS™ is designed with a modular architecture that allows projects to start with smaller footprints and scale up to utility-grade developments spanning thousands of acres. Each module is a self-contained unit capable of generating approximately 1 MW per acre, making the system adaptable for both pilot deployments and large commercial rollouts.
STEGS™ uses proven turbine and generator technology familiar to utilities and grid operators. This reduces integration risk and ensures compatibility with existing transmission systems. Because it produces dispatchable baseload electricity, STEGS™ strengthens grid resilience by filling the gaps left by intermittent renewables such as PV solar and wind.
STEGS™ is built around robust, industrial-grade components with an operational lifespan expected to exceed several decades. Unlike PV panels or wind turbines, the thermal storage blocks and turbine systems require minimal degradation management, lowering lifecycle costs. Routine maintenance is straightforward and leverages well-established power plant service protocols, giving STEGS™ a reliability profile comparable to traditional thermal plants—but without fossil fuels.
