Consortium partners

The EELS project is carried out by the following partners:


The mission of ECN is to develop innovative technologies for sustainable energy system in cooperation with and for the market. In this project the role of ECN consists of the development and testing of the absorber system, project management and dissemination of the results to the public. ECN will also supply support in sorbent development in the form of lab measurements.


Friesland Campina is world-leading producer of dairy products. One of their most energy-intensive processes is the spray drying of milk(powder). This process would greatly benefit from the proposed system, provided the system performance meets the requirements and can be integrated in the process. The role of Friesland Campina is therefore to provide the requirements for the system and identifying process integration challenges.

DOW Benelux

DOW has developed various chemicals for application in sustainable energy systems. These include sorbents for capturing carbon dioxide and heat storage materials. In this project, their focus will be on the development of a liquid sorbent to remove water vapor and supply hot, dry air.


Unilever is world-wide producer of food-related products. Many of their products require to be dried under well-controlled conditions. These drying processes could benefit from the liquid sorption drying system. The role of Unilever is to provide requirements for the system and identifying process integration challenges. Unilever also has an experimental setup for closed loop drying which can be adapted for liquid sorbents.

Bronswerk Heat Transfer

Bronswerk Heat Transfer is a manufacturer of heat exchangers and related equipment and are constantly looking for opportunities to strengthen their position in the field of sustainable technologies. Their role in the project is to monitor the proposed solutions regarding manufacturability and costs. This leads to a global design of a full-scale system and a first cost-estimate of such system.

Third parties involved:

Institute for Sustainable Process Technology

The Institute for Sustainable Process technology (ISPT) is a co-operation between industry, universities, and knowledge institutes, which aims at speeding up innovation processes and make them more efficient than they are at present. Apart from developing knowledge, the institute aims at the development, demonstration and application of breakthrough technology with a special focus on process technology. The role of ISPT is to disseminate results to the public and relevant partners.

Dutch Working Party on Drying (NWGD)

The NWGD is the forum in The Netherlands for exchange of knowledge and experience regarding drying and all related aspects. This exchange can take place between companies or between companies and knowledge providers such as universities, institutes and advisors. This leads to optimization and innovation of drying processes and yields clarity regarding priorities for research and development. The NWGD will organize a workshop as part of the dissemination of the project results to the relevant parties active in drying.
