About us

Energy research Centre of the Netherlands

Welcome to the Energy research Centre of the Netherlands, the largest research centre in the Netherlands in the field of energy. At this moment ECN employs about 900 people. ECN is situated in the dunes near Petten, a village in the north-western part of Holland. ECN carries out research in the field of energy. In search for sustainable energy supply and consumption, the researchers move between fundamental research at universities and appliance of knowledge and technologies in practice. The technology developed at ECN has a large impact on daily life. For example, solar systems are placed on roofs of houses and modern wind mills are spinning in the field by means of technology developed by ECN. With this the institute exerts an important function for the society of today and tomorrow. The main goal of the program Energy Efficiency in the Industry (EEI) is to develop innovative solutions for the reduction of energy and raw-materials use in industry together with our industrial partners.

 

Since 1998, ECN has been developing nanoporous membranes for gas separation, pervaporation and nanofiltration applications. Over the years, the group has developed an outstanding reputation and has developed a solid intellectual property position. The group has been focused on the scaling up the sol-gel membrane technology. It was among the first to show the productivity of silica and silica based membranes on one meter long tubes.

Twente University, MESA+ institute

The University of Twente offers research and degree programmes in technology, and in the social and behavioural sciences. MESA+ Institute for Nanotechnology is part of the University of Twente. The institute employs 500 people of which 275 are PhD students or postdoctoral researchers. With its NanoLab facilities the institute holds 1250 m2 of clean room space and state of the art research equipment. MESA+ has an integral turnover of 45 million euro per year of which 60% is acquired in competition from external sources.

 
MESA+ combines the disciplines of physics, electrical engineering, chemistry and mathematics, and encompasses multidisciplinary competences in the areas of microsystem technology, materials science, bottom-up chemistry, photonics and biophysical engineering. The institute aims to carry out excellent and relevant research in the field of nanotechnology, and post-graduate education.  The institute also aims to promote the transfer of knowledge to society and new technology, and has been the breeding place for more than 40 high-tech start-ups to date.

How it started

The development of the HybSi® membrane system started as a result of a discussion during the 12th International Sol-Gel Workshop in Sydney, Australia, August 2003. In a small group, Andre ten Elshof and Jaap Vente discussed the issues related to the hydrothermal stability of nanoporous silica based materials and possible ways of how to prolong the longevity of the membrane material. The most reasonable idea was to replace as many Si-O-Si bonds as possible by Si-CnHm-Si bonds. Back at the University of Twente, Ph.D. student Ashima Sah started to work on this topic, supervised by Andre ten Elshof and in collaboration with post-doc Hessel Castricum. After two years and many setbacks, indeed a membrane was formed that was somewhat selective. The recipe was quickly scaled up to a tubular geometry and put to test at high temperatures at Energy research Centre of the Netherlands. Despite some performance decline during the first month of operation, it survived for more than two years of continuous testing in dehydration pervaporation at 150°C. The performance and stability has been further improved and is much superior over any other pervaporation membrane known to date. Therefore the application window is much broader. In the end the implementation of this membrane in the (process) industry will lead to larger improvements in energy efficiency and in lower costs.

Key people


Jaap Vente, group leader Membrane Technology

Jaap Vente studied materials science and engineering at the Unversity of Technology Delft. The topic of his master thesis was molten carbonate fuel cells. Subsequently, he moved to University of Leiden to study the magnetochemical and crystallographic properties of complex iridium oxides. In 1994, he accepted a position of post-doctoral research assistant at the Inorganic Chemistry Laboratory of the University of Oxford. After 4 years, he moved to Mexico to become an investigator at CINVESTAV. He started to work for Energy research Centre of the Netherlands on membrane technology to enhance the industrial energy efficiency in 2003. Since 2007, he is group leader Membrane Technology.


Henk van Veen, senior scientist and project manager Membrane Technology

Henk van Veen obtained a BSc degree in Chemical Engineering in 1986. His graduation work in the field of polymeric membranes for the separation of CO2 from CH4 was performed in the Membrane Technology group at Twente University. Subsequently, he started to work at the Energy research Centre of the Netherlands in the field of ceramic membranes. After being managing several projects he became responsible for the coordination of all activities in the field of membrane applications within ECN in 2000. Since 2007 Henk is deputy Group leader Membrane Technology. The work focuses towards energy and costs savings using membranes including the use of membranes in (bio) conversion processes. Further, Henk is a permanent member of the graduation committee of the Hogeschool Utrecht.


Rob Kreiter, scientist and project manager Membrane Technology

Rob Kreiter studied chemistry at Utrecht University with a minor in inorganic chemistry and catalysis and a major in organometallic chemistry and homogeneous catalysis.

Subsequently he did his Ph.D. on triarylphosphine-based complexes and dendrimers that show positive dendritic effects in C-C bond formation. In 2005 he moved to ECN to work on sol-gel membranes for molecular separations. His current interests are the development of polymer-based and sol-gel membranes and materials. He is actively involved in the search for new generations of HybSi® membranes. Next to the materials science he is responsible for the development of olefin/paraffin separation processes using membranes.
