About

EXORA: Waste Heat-Driven Adsorption Cooling with Advanced Metal-Organic Frameworks

EXORA is a Paris-based deeptech startup (TRL 4/5) developing a next-generation adsorption cooling module that recovers low-grade industrial waste heat from 35°C and converts it into useful cold at 5-22°C, with water as the refrigerant and a proprietary advanced material as sorbent.

Technology
Unlike conventional compression chillers, our system requires up to 90% less electrical input, operates with zero fluorinated refrigerants, and can valorize heat sources that existing absorption systems (LiBr, NH3) cannot exploit below ~80°C. The new sorbent represents a significant performance step-change over commercial silica gel or zeolite-based adsorption chillers.

Value proposition
Our system addresses two major decarbonization levers simultaneously: reducing electricity consumption for cooling and valorizing waste heat that is currently dissipated. Target applications include industrial sites with continuous low-grade waste heat (food processing, pharma, datacenters, chemical plants), greenhouses, and district cooling networks.

What we are looking for
We are seeking partners to form a transnational consortium under CM2026-07, specifically:

  • Industrial end-users or site operators able to provide a real waste heat source for demonstration (35-200°C range)

  • Research or engineering organizations with expertise in thermal system integration, heat exchanger design, or sorbent characterization

  • Technology integrators or OEMs in HVAC, industrial refrigeration, or process cooling

The collaboration would aim to advance our system from TRL 4/5 toward TRL 6/7 through real-environment testing, performance characterization, and integration validation.

Why this consortium fits CM2026-07
EXORA's innovation directly addresses the CETPartnership's TRI 4 objective of efficient, zero-emission heating and cooling solutions. Our technology offers a market-ready pathway to decarbonize industrial cooling while exploiting currently wasted thermal energy across European industrial sites.
