High-Temperature Heat Recovery and Storage System for Industrial Decarbonization

energyTestedTRL 5

Imagine a super-powered heat pump that can take lukewarm waste heat and boost it to temperatures hot enough for industrial cooking or cleaning. It also includes a thermal battery that saves this heat for later, so factories don't have to rely on the sun shining or waste heat being available at that exact moment. An AI brain manages everything to make sure the energy is used as efficiently as possible.

The business problem

What needed solving

Industrial sectors rely on fossil fuels for high-temperature heat, contributing to 552 Mt/a of CO2 emissions. Current renewable options often cannot reach the 150-250 °C required for many processes.

The solution

What was built

A 200 kWth pilot system featuring a Stirling-based high-temperature heat pump, a bio-inspired phase change material storage system, and an AI-driven digital twin for energy control.

Who can put this to work

Food & Beverage

Target: Dairy and fish oil processors

If you are a dairy processor dealing with high energy costs for heating processes — this project developed a Stirling-based heat pump and storage system that provides heat up to 250 °C. This allows you to reuse waste heat and solar energy to reduce CO2 emissions. It targets a COP of up to 2.8 for temperature ratios of 1.2.

Textiles
SME
Target: Fabric and leather manufacturers

If you are a textile manufacturer dealing with heavy reliance on fossil fuels for high-temperature steam — this project developed a heat upgrade system that reaches 150-250 °C. By integrating bio-inspired storage, you can decouple heat production from availability. This helps reduce GHG emissions up to 145 gCO2/kWh.

Chemicals
enterprise
Target: Petrochemical plants

If you are a petrochemical plant dealing with intermittent renewable energy sources — this project developed a Control & Integration Twin (CIT) and thermal storage. This ensures a reliable heat delivery even when solar or waste heat is low. It aims for an annual reduction of 20 million tons of CO2 across the sector.

Frequently asked

Quick answers

What is the cost or price of the system?

Based on available project data, specific pricing or cost per unit is not provided as the project is currently at the validation stage.

Can this be scaled to a full industrial plant?

The project is validating a 200 kWth pilot to emulate industrial needs. It aims to extend findings to sectors like Pulp & Paper and Basic Metals to prove scalability.

How is the IP or licensing handled?

Based on available project data, there is no specific mention of licensing terms or patent ownership in the provided summary.

How does this integrate with existing machinery?

Integration is managed via a Digital Twin (CIT) and AI-driven control systems that optimize energy management and provide self-assessment tools for industrial sites.

What is the timeline for deployment?

The project runs from May 2023 to April 2027, focusing on reaching TRL 5 validation during this period.

Consortium

Who built it

The consortium is heavily weighted toward commercial application, with 15 partners across 11 countries. Notably, 60% of the partners are from industry, and 9 are SMEs, indicating a strong focus on market viability and practical implementation rather than purely academic research.
