Automatic differentiation gives derivatives and gradients of numerical programs with respect to the input parameters. This is essential when a numerical model is to be fitted to data, updated to new observations and when the model controls are to be optimized for a desired outcome. Numerical models are...
We are working to determine and predict the transport-related and thermodynamic properties of fluids. This knowledge is essential in order to optimize design and operation of processing equipment used in the energy sector. Behind the Scenes from the HPC-PE Rig We work in these areas: Main fluids: CO2...

Over a third of the energy consumed in Norway is...
The vision of smart cities is to facilitate better-informed and optimal preparation and use of the infrastructure services by means of ICT. This provides a potential for significant savings both in terms of cost and energy consumption, which is necessary to ensure sustainability of the modern society...
...parts of the power system. Examples include the integration of renewable power plants, high-voltage direct current (HVDC) transmission and electrification of the oil and gas sector. Commonly, electrical energy must pass through several power electronic conversion stages on its journey from generation to...
Electrification of the transport sector is key to reaching the national and international targets for reduction of local and global emissions. Large-scale electrification of transport on road, rail, sea and in air requires reliable and efficient charging infrastructure. In the future, the demand for charging...
...as temperature, light and nutrient availability, salinity, and oxygen concentrations. Thus, we may compare the suitability of different locations for aquaculture, and in particular avoid sites with particularly adverse conditions and assess different cultivation strategies and scenarios. It is also possible...
An introduction of autonomous vehicles will make the transportation of passengers and freight more efficient and help transition the transport sector towards more environmentally sustainable solutions. Autonomous vehicles are commonly less space-consuming – an important characteristic for the urban environment...
Where should the fisher cast her net to obtain the largest catch of her target species while keeping energy use and expenditures at a minimum? How can we improve the design and operation of fishing vessels to reduce overall CO2 emissions from the fishing fleet? Can we detect illegal or unwanted fishing...
...reason, HVDC transmission is playing a gradually increasing role in modern power systems, exemplified by stable growth in the number of interconnections and levels of installed power. Even more relevant is the application of HVDC conversion systems in offshore settings where the use of subsea cables limits...
...conversion of hydrogen in a fuel cell. Also hybrid solutions are a possibility. Transportation includes conventional passenger cars, heavy cargo, ships and railway. The battery in the vehicles can also be used as mobile storage which is connected to the electrical grid, e.g. if the car charges at home or...
...processes and design of the product, the material technology plays a key role. Mechanics and structural engineering We work with research and development activities in mechanics and structural engineering, where the goal is to find component- and design solutions that utilize material properties and design...
Geothermal energy systems cover systems for both shallow and deep geothermal wells. Shallow geothermal boreholes, 50 - 200 m, are used as heat source or sink for heat pumping systems. Deep geothermal wells, typically 1-10 km, can retrieve heat with higher temperature. Heat with high temperature can be...

The vertical dimension refers to the global arena from the UN to the municipal sphere and the links between these, and the local capacity building that is necessary to translate...
Wind farms are complex dynamic systems and operating them in a smart way requires expertise in various fields to maximise the overall profitability. Wind farm control (WFC) requires multidisciplinary knowledge including aerodynamics, materials and structural responses, electrical components, control...
...more secure, efficient, and accessible transportation system. At SINTEF, we have gained substantial experience in conducting R&D on C-ITS projects for the industry. C-ITS is the technology that specifies how the ITS components (individual road user, local infrastructure, and surrounding environment)...
...learn how to perform complicated tasks through trial and error. The method The method is particularly suited for when the system and the goal can be described with an environment (e.g. a labyrinth), an observer (a sensor), an agent (a control system), and a reward system modelling an objective (get out of...
...leader in the field of improving energy efficiency in shops and other energy-intensive buildings by means of its participation in projects such as 'CREATIV', 'INTERACT' and 'SuperSmart-Rack', among others. Furthermore, SINTEF is preparing new and integrated energy systems for commercial building complexes...
