Zero Charge Technologies provides DELTΔ‑T®, a flexible polymer thin‑film that converts low‑grade waste heat below 100 °C into electricity using embedded thermoelectric nanostructures. The film can be applied to pipes, hulls, data‑center racks, and building façades, and also functions as a solid‑state refrigerant for heating or cooling, enabling on‑site energy recovery and HVAC integration. The company licenses the material to OEMs and offers a cloud analytics platform for performance monitoring.

Problem
A large proportion of industrial and commercial processes release low‑grade waste heat that is not captured, leading to unnecessary energy loss and higher carbon emissions. Existing thermoelectric solutions are bulky, inefficient, and unsuitable for temperatures below the boiling point.
Solution
Zero Charge Technologies offers DELTΔ‑T®, a flexible, heat‑sensitive thin‑film that directly converts low‑grade waste heat into usable electricity without moving parts. The material conforms to any heated surface—pipes, hulls, or building envelopes—and generates power at temperatures below boiling, delivering carbon‑free electricity on‑site. Because the film also functions as a refrigerant agent, it can simultaneously provide cooling or heating, reducing reliance on conventional HVAC systems. The technology is delivered through a global licensing model, allowing manufacturers to integrate the film into existing products or install it as retrofit panels, while a cloud‑based analytics suite monitors performance and optimizes energy capture.
Target Audience
Primary customers are industrial facilities and utilities that generate waste heat (oil & gas, power generation, data centers), marine vessel manufacturers, automotive and hybrid‑vehicle OEMs, and commercial‑building developers seeking on‑site energy recovery and HVAC integration.
