The multi-year programme will in 2007 focus on the following subjects, among others: aerodynamic induction modelling, flow interaction between rotor, tower and nacelle, structural coupling in
The project comprises phase 1 of a fact-finding and development programme to ensure relevant offers of PV lessons. The objective is to offer architects, advisers, designers and craftsmen working with
The project develops components with a new composition of materials and more cost-effective production processes for PEM fuel cells to boost performance and reduce costs. The results are demonstrated
The project will shed light on the role of district heating in a future flexible energy system. Focus will be on reducing loss of energy and dynamic use of familiar and new energy technologies such as
By interviewing energy-intensive companies and power companies, the project aims at establishing how the energy services concept can form part of the work of companies subject to emission allowances
The experience gained in Germany suggests that grid-connected PV units cannot use the standard design optimally under North European conditions. This project collects key data from Danish PV systems
Methods are devised for online control of biofuel pellet quality using, for instance, mechanical durability, fine particles, pellet density and length and particle size as parameters. The new methods
The project focuses on developing an SOFC stack technology which is efficient under realistic operating conditions in both small and large facilities. For this purpose, a test facility, for instance
The project enables Denmark to resume its activities in the IEA implementing agreement on hybrid and electric vehicle (IA-HEV), dealing with, for instance, electric cars with batteries and fuel cells
These two projects continue the publication of the eight-page news magazine Bioenergy Research with six issues a year. The magazine goes over new research results and features debate-triggering and
One of the current topics of the IEA’s cooperation on research in fuel wood chips is forecasts of fuel resources, technical production, wood fuel transport, valuation, long-term storage of decomposed
Being a Danish knowledge centre, Risø National Laboratory-DTU collects and communicates information about Danish energy publications to the IEA database ETDEWEB (www.etde.org/etdeweb). Moreover
The project plans and builds a newly developed standard house of low-energy class 1 (from project ENS-33031-0089), whose energy performance and indoor climate are documented by detailed measurements
At present, there are no safety-technical testing facilities for hydrogen and fuel cells in Denmark, and there is hardly any commercial basis for running such facilities. The project identifies the
The project develops a design complex for a district heating system, which, by using new technologies, materials and operating modes, will be able to lower total costs by so much that tomorrow’s low
The purpose of the project has been to make a book on the best examples of low-energy buildings in Denmark. The book was completed in autumn 2011 with Solar City Copenhagen as publisher and the Danish
Aalborg University and Risø/DTU have developed a model to estimate responses and structural reliability of wind turbines under normal operation. Various Monte Carlo simulation algorithms were tested
Process optimisation is performed at the MaxiFuels pilot plant at DTU in the context of, for instance, membrane distillation of ethanol, separation of the permanent residual fraction from glucose
The Castor plant’s gasification reactor is developed to gasify wood pellets instead of wood chips, and an aesthetic and technically efficient design of the plant is developed for adaptation into a
