Actions & Deliverables

The project aims to deliver answers to some major issues in ORC technology and also aims at developing methodology to further develop industrial realisations and prototypes of technological components. These methods will be used in development projects after this project.

In order to create the next generation of Organic Rankine Cycles and to facilitate market penetration of this technology, a multi-disciplinary approach will be used focusing on 5 major challenges identified from the market survey and the industrial contacts.

  • challenge 1 – Improving the efficiency
  • challenge 2 – Control over dynamic behavior
  • challenge 3 – Reducing the design time
  • challenge 4 – Test-infrastructure
  • challenge 5 – Economical analysis

In a first step the multi-disciplinary research team will optimise existing systems by better understanding ORC systems from both the thermodynamic, control and economic point of view. Secondly the project aims at pushing the boundaries of technological development by introducing new components into the cycles and design the cycles for new applications. In this step all components of the cycle are targeted: heat exchangers and expanders, but also their interaction and control. Throughout the project, technological advances will be put against financial and economical boundary conditions.

The ORCNext objectives are explained in more detail in the 6 work packages:

During the course of the project the abstracts of the different deliverables achieved of every workpackage will be put online in the subfolders of this webpage. The full reports can be requested by sending an e-mail to
