The EU-funded DECAGONE project is launched

DECAGONE will develop a cutting-edge process to recover waste heat into electricity based on the Organic Rankine Cycle technology

Paris, 21st July 2022: The “DECAGONE” project - DEmonstrator of industrial CArbon-free power Generation from ORC-based waste-heat-to-Energy systems – started officially on 1st June 2022. The project is funded by the European Union’s Research and Innovation Framework Programme Horizon Europe with a budget of €14 million and a duration of 4 years.

The ambition of DECAGONE is to develop state-of-the-art technological solutions to increase energy efficiency in industry and reduce Greenhouse Gas (GHG) and air pollutant emissions from industry by recovering and converting excess industrial heat (waste) into electricity.

The solution, developed by a consortium of 16 partners from 10 European countries, is based on the Organic Rankine Cycle (ORC) technology. It will achieve scalability to higher power levels, improve cost-effectiveness, wider input temperature ranges, and a significant reduction in system size, allowing wider take-up of heat recovery and its conversion to electricity from more industrial processes. The solution will be demonstrated in the TŘINECKÉ ŽELEZÁRNY steel Mill in the Czech Republic with a 2 MW installation.

“Heat, and more broadly the lost energy in industrial processes, represents a significant under-exploited source of energy. DECAGONE enables the recovery of waste energy in the industrial plants by its conversion into heat and electricity”, says Gilles David, CEO of the project coordinator Enertime.

The ORC-based system will use enhanced heat recovery designs and disruptive turbomachinery. The proposed break-through architecture of the turbine is tailored for increased compacity, higher availability and safety, and cost reduction with near-zero maintenance. The consortium will also improve organic fluids or mixtures for higher stability and improved transposability to other industries. The project ensures an efficient and smart integration of advanced monitoring using innovative probes, the Internet of Things (IoT), and machine learning algorithms for real-time efficiency improvement. The potential of self-consumption in industrial plants at a large industrial scale will be fully exploited.

Within the scope of the project, the potential of this technology will be evaluated in six other heat-intensive industrial sectors. Market potential and Europe-wide transposability for potential use cases (aluminum, glass, gas-energy, oil & gas and refineries, LNG terminals, and cement) will be evaluated. New financing and business models will also be explored, to support long-term operations of the erected assets, coping with long-lasting and resilient industrial processes. The use of the ESCO model to contract, finance, and operate energy efficiency facilities will be part of this project, preparing for the future operation of the facility by a specialized company. Lastly, the project consortium will disseminate the project results across Europe by relying on their European partners and in coordination with regional energy agencies.
