Built to Solve a Problem That Has Been Ignored for Decades

Industrial facilities — steel mills, cement plants, glass furnaces, chemical processors — operate at temperatures that dwarf anything in the built environment. A significant fraction of the energy they consume leaves as heat through exhaust stacks, cooling systems, and radiated surfaces. Most of it has no economic use.

Existing waste heat recovery technologies work well at the high end of the temperature spectrum. Below roughly 500°C, the options narrow sharply. The equipment is expensive, the efficiency drops, and the economics rarely close without subsidies. That gap is where most industrial waste heat actually lives.

NISO Energy was founded to close that gap. We are developing a modular system designed specifically for the mid-range temperature conditions that existing solutions handle poorly — and doing it under a commercial model that removes the capital barrier for host facilities.

We are a deep-tech company, which means we are solving a hard engineering problem before we scale a business. Our first priority is demonstrating that the system performs as designed under real industrial conditions.

We are pursuing a single, well-defined pilot in the steel sector. Steel was chosen because it presents the clearest combination of heat availability, operational continuity, and willingness to engage with new technology. A successful steel pilot is the foundation for everything that follows.

We do not make performance promises we cannot yet support with data. We are transparent about what we know, what we are testing, and what remains to be proven.
