Within the EU, up to one third of energy for industrial thermal processes is lost through waste heat. The potential power generation from this resource through full use of ORC technology would represent around 7,6 million tons of CO2 equivalent saved per year at the European level.

The overall objective of DECAGONE is to develop an innovative technology for the exploitation of industrial waste heat.The proposed key-innovations will make ORC systems (Organic Rankine Cycle)  more efficient, more cost-effective, and adaptable to more diverse sectors for broad industrial uptake. They will be demonstrated by a 2 MW unit integrated into a steel production plant, located in Třinec, Czech Republic and owned by Třinecké železárny, mother company of partner Energetika Třinec.

The project follows three objectives:

  • Increased efficiency
  • Lower Total Cost of Ownership
  • System replicability and market potential

In this project, SINTEF is responsible for:

  1. Developing and evaluating basic system designs, which produces the initial system performance evaluations as well as operating conditions and performance requirements for the main system components
  2. Heat exchanger design – SINTEF is tasked with designing optimal heat exchangers for the demonstrator, and evaluating and comparing alternative technology options that could be applicable in future applications.

You can find more about DECAGON on the project website.

It associates a total of 16 partners from 10 countries in order to demonstrate the potential of the ORC (Organic Rankine Cycle) technology for the recovery of waste heat in all sectors of European industry, and the interest of the ESCO (Energy service company) model to accelerate the diffusion of this technology.
