To extend the life of gear oil - not least for use in offshore wind turbiens - the project aims to investigate whether nano-filtration using CJC filters (cellulose fibres) with zeolites eliminates the
The project constituted a phase of the strategic partnership between Risø DTU and the wind turbine industry on developing an aeroelastic design complex. The project worked with the following issues
IEA task 42 identifies existing biorefineries and process potential, prepares common definitions and standards for classifying and assessing technical, financial and environmental advantages and
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 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
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
The developed CFD model shows qualitative and quantitative correlation between the model and experiments in a lab scale reactor. When the developed model was implemented in the full-scale plant, it
To develop the market for solid biofuels within the EU, standards are urgently needed. Based on a mandate given by the EC, CEN TC 335 "Solid Biofuels" currently develops such standards based on the
Nanotechnology can provide possibilities for obtaining new valuable information regarding performance and corrosion protection in power plants. In general, the desired performance of the contact
Use of cellulose for biofuel production requires the cellulose to be degraded into small molecules. Several different enzymes can be used for this prupose. The project aims to develop a method for
Today, wind turbine control systems are designed separately from its structural, aerodynamic qualities, but to achieve cheaper, more reliable wind turbines, the design phases need to be united into
The project studied sediment bed conditions, scour/erosion, and quick-sand-like conditions that may occur due to the effects caused by wave and current action. Illustration from laboratory experiment
On a hot windy summer day, with beautiful clouds in the sky, the air is full of turbulence, like a hot pot of boiling water. In these unsteady surroundings a bird of prey is hovering, completely still
