The interface
Control the Heat with Pyra Pulse.
Transform complex thermodynamics into intuitive management. Our dashboard uses a material 3D render of your silo to show real-time thermal saturation.
Predictive autonomy
Know exactly how many days of heat you have left based on real-time weather forecasts and historical consumption patterns.
Flow optimization
Experience smart, automated routing between high-pressure steam for electricity generation and direct industrial heating.
Grid balancing
Maximize ROI by automatically charging the core when renewable supply is high and market prices are at their lowest.

How It works
Store the power in the heart of the earth.
1 – The charge
Excess wind and solar energy power our patented honeycomb heat exchangers.
2 – The core
The heat is transferred to the sand, creating a massive thermal reservoir with minimal loss.
3 – The release
On-demand energy for district heating, steam turbines, or industrial furnaces.
1 – Call
Type or speak your request, a thought, a task, a question.
2 – Awaken
The assistant weaves the answer, shaping text or insight in seconds.
3 – Embrace
Take what appears — refine it, use it, and move forward with ease.

The Pyra impact
Elemental power at your side delivering sustainable growth.
Cost efficiency
Drastically reduce energy overhead by capturing low-cost renewable surges and storing them for high-demand periods.
Carbon neutrality
Replace traditional gas burners with high-temperature thermal energy. Reach your net-zero targets without compromise.
Grid resilience
Protect your operations from price spikes and grid instability with a reliable, local reserve of high-grade heat.
Absolute safety
Non-flammable, non-toxic, and non-explosive. Inert silica sand is the safest medium for large-scale energy storage.
Operational longevity
A generational asset with 30+ years of life. Unlike chemical batteries, Pyra experiences zero degradation over time.
Versatile output
Seamlessly switch between high-pressure steam for electricity and direct heat for complex industrial processes.
Testimonials
What industry leaders say about the Pyra experience.
Switching to Pyra was the turning point for our carbon-neutral goals. Storing weeks of energy in simple sand felt like magic until we saw the massive cost savings on our steam production.
