Sunamp designs and manufactures space-saving thermal storage that makes American homes, buildings and vehicles more energy efficient and sustainable, while reducing carbon emissions and optimizing renewables.
Our thermal batteries support the electrification of heat.
They work with heat pumps, wind and solar, grid and microgrid electricity, waste heat, combined heat and power (CHP) and boilers.
And store 4 to 10 times more energy than conventional materials.
Sustained with Plentigrade
Sunamp’s patented Plentigrade technology stores energy in our high-performance phase change materials and releases it to give hot water, heating or cooling on demand.
Long lifespan with best-in-class reliability rating.
Wide temperature range
Plentigrade discharges at a consistent, controlled temperature.
Reliably, safely and efficiently.
This means our thermal batteries can be used to freeze -22°F (-30°C), refrigerate 41°F (5°C) or warm 136°F (58°C), and even sterilize 244°F (118°C) in many different settings.
Making homes, buildings and industry more energy efficient and sustainable
Combining low-cost materials, exceptional long-life and recyclability, our energy-dense batteries deliver a low-carbon solution for freezing, cooling, heating, steam, and hot water.
About us in the USA
At Sunamp, we make and sell batteries that store heat and discharge it as energy that can be used for hot water, heating and cooling. By doing so, our products cut carbon emissions and help us all meet the challenge of achieving net zero by 2035.
We’re an ambitious company that’s growing fast around the world. We design and manufacture our thermal battery products at our headquarters near Edinburgh, in the UK and recently expanded our operations to include an office in New York.
