The Energy Research Centre of the Netherlands (ECN) is one of the largest energy research institute in Europe and holds a strong international position. With and for the market, ECN develops knowledge and technology that enable a transition to a sustainable energy system. The main office is located in Petten. ECN also has offices in Amsterdam, Eindhoven, Wieringermeer, Brussels and China. ECN has a staff of about 550 employees. As of April 1, 2018, the Energy Research Centre of the Netherlands (ECN) has joined forces with the Netherlands Organisation for Applied Scientific Research (TNO) and is now 'ECN part of TNO', Our aim is to accelerate the energy transition in The Netherlands and beyond. From January 2020, the name 'ECN part of TNO' will be replaced by TNO Energy Transition, announced officially on October 10, 2019. Activities ECN's research and technology development focuses on: Solar Energy Wind Energy Biomass Environmental research Energy efficiency Policy Studies The total package of sustainable energy generation, clean use of fossil fuels and reduction of total energy use are key topics. ECN also conducts research on future opportunities and economic backgrounds in the field of energy. Publications ECN researchers disseminate their results in publications such as reports, peer reviewed articles in scientific and professional journals, conference contributions and books and chapters in books. In 2011, ECN published 481 reports (public and confidential) and 176 articles in scientific journals. International position ECN participates in international projects, advises authorities and collaborates with the industry in the Netherlands, Europe and worldwide. A number of examples: EERA: together with nine other research organisations in Europe, ECN founded the European Energy Research Alliance (EERA). The aim is to harmonise the research programmes through joint research and optimal deployment of facilities. ADEM: an initiative of ECN and three collaborating Technical Universities (Delft University of Technology, Eindhoven University of Technology, and the University of Twente). They wish to give strong impetus to Dutch materials research in relation to energy technology. FLOW: the FLOW programme enables Dutch businesses to take a leading position on the international market for offshore wind farms. The programme was initiated by RWE, Eneco, TenneT, Ballast Nedam, Van Oord, IHC Merwede, 2-B Energy, XECM Darwind, ECN and Delft University of technology. Solliance: Solliance is a collaboration of TNO, Eindhoven University of Technology, ECN and IMEC, focusing on research and development in the field of thin film solar panels (PV)
