Wind turbines are continuously growing in size, and with the increasing focus on offshore installations, accurately analysis of wind loads and intermittency is of great importance.Windfarms typically consists of a large number of such turbines, and the wind interaction between the turbines must be known to be able to optimize the windfarm with respect to electricity production and to low maintenance cost. Such optimization strongly relies on the control systems used to operate the windfarm.
Climate and environment Energy efficiency
SINTEF creates future-oriented and innovative solutions for energy efficiency in industry, transport and buildings.
Energy efficiency is a vital tool for reducing energy consumption and thus the need for new power sources. This is also an important area for reducing greenhouse gas emissions when fossil fuels are the energy source. SINTEF conducts research on energy efficiency in industry, transportation and in the construction industry. An important research area is efficiency in Norway's power-intensive industries, and the utilization of waste heat.
The activity og SINTEF Building and Infrastructure within building physics comprise moisture and heat transmission, pressure ratio, air and rain resistance in materials and constructions, as well as energy use in buildings. Our core expertise is practical building physics, by transferring new knowledge and research findings into solutions for the building industry.
Energy efficiency and increased heating comfort has resulted in modern buildings being more airtight than previous building constructions. Tight buildings have reduced the uncontrolled ventilation, without this being sufficiently compensated through controlled ventilation. Both in existing and future buildings, it is therefore important to install ventilation plants that are satisfactory with regard to air flow rate, reliability, comfort, energy efficiency and usability.
We perform research and development of burners to meet stringent emission limits in various applications from advanced domestic appliances to gas turbines with CCS, using a wide spectrum of experimental and numerical tools, both at lab and pilot scales.
Catalysis is involved in 85-90 % of all chemicals production. SINTEF has extensive experience within both homogeneous and heterogeneous catalysis. Our projects are often directed towards understanding the operation of the catalyst and the interplay between the catalyst and its process. We work closely with partners in academia and Norwegian and international industry.
CO2 has gone through a renaissance as refrigerant due to the need to replace the chemical refrigerants with highly negative environmental impact. The main applications where CO2 systems has been commercialized so far are heat pump water heaters (heat pumps for heating of sanitary water), refrigeration systems for supermarkets and within small size commercial refrigeration. SINTEF-NTNU initiated this development in the end of the 1980s. More than 4 million systems are installed to date, corresponding to a turnover of more than 200 billion NOK.
We have accumulated more than 15 years experience in new combustion processes based on the use of unconventional fuels (rich in hydrogen) and new oxidizers like oxyfuel mixtures which are common in power and industrial technologies with CO2 Capture and Sequestration (CCS). We also support the development of new CCS concepts and bring them to pilot testing as we do for the promising Chemical Looping Combustion (CLC) technology.
The management of water and energy resources is practised by public authorities at municipal, regional and national levels. In special cases, clarification may be required in addition to what is usually needed in more normal management processes. There may be a need for the assistance of experts with special qualifications with regard to a certain method or issue, or with experience from the water system in question.
Drying of food (thermal processing of meat, fish, vegetables and seaweed / kelp) is the most important method of preservation in the world. Drying gives a stable product with a longer shelf life and a product that is easy to distribute. However, drying is energy-intensive, and the quality of the final product depends on the process. Researchers at Process Technology at SINTEF Fisheries and Aquaculture possesses expertise in both chemistry and technology in order best to solve interdisciplinary challenges within drying of foodstuffs. For an energy efficient and environmentally friendly drying process will reuse and utilization of waste heat using heat pumps be highly relevant. Partial drying can be combined with salting for the production of cured meat. During production of cured meat, lamb ribs, cheese and dried fish will optimal management and control of temperature and humidity in the greenhouse stock be important for quality and yield.
Building materials and constructions are supposed to have a very long service life under partly rough circumstances. It is essential that the durability of a product or a component is suitable, whereas reduced durability often may have serious consequences, such as e.g. air or water leakages.
An EPD (Environmental Product Declaration) is a short document that sums up the environmental strain of a product. EPDs are based on life cycle assessments of environmental data from the withdrawal of raw materials, production, application phase and disposal. EPDs are becoming increasingly important for building materials in the Norwegian market.
Production of Ferroalloys (i.e. Ferrosilicon/Silicon- and Ferromanganese) is a strong and significant land-based industry in Norway. The results from the cooperation between the industry and academia (SINTEF/NTNU) in Norway are basic knowledge regarding thermodynamics- and kinetic-data as well as reaction mechanisms within core processes and environmental issues.
Cooling is a crucial aspect of electronics design, all the way from high-power industrial applications to personal computers. We investigate and develop ways of creating more efficient and reliable cooling systems, using magnetic nanofluids (ferrofluids).
We develop specialized models and methods related to the flow of gases and liquids, and which is unavailable in commercial software. We have several in-house 1D and 3D CFD codes. Furthermore, we take part in the design of laboratory set-ups to be used for model development. We deliver data, analyses of models and methods, or software.

In our projects we are using unique infrastructure to investigate biomass gasification, fuel synthesis and heat and power production together with both national and international industry and research partners.
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 utilised directly, e.g. for district heating, or as a heat as source for running a heat-to-power cycle.
We have extensive experience in developing detailed heat exchanger models for various industrial purposes. The models have a level of detail that is suitable for linking and use with various process simulation tools to study how given designs will behave and affect reliability and energy consumption under various conditions. We work with both users and manufacturers of heat exchangers and may also help in developing new concepts and use of new materials.
SINTEF has extensive and versatile competence in development of heat pump technology. We have more than 60 years' experience within research and development of heat pump technology. Through close cooperation with NTNU, engineer and researcher education is integrated in our larger, long term projects to facilitate an efficient knowledge transfer to industry and commerce.
Installations for waterborne heating has been common in both commercial buildings and residences for many years. Such installations provide flexibility in the choice of energy source. Because of constantly stricter regulations regarding energy efficiency, modern buildings require less and less energy supply in the form of heat. One of the challenges in the future is effective operation of heating installations with low temperatures and small quantities of water.
Hydrogen will be an important supplement to electricity as an energy carrier in future sustainable energy systems. In addition to being fuel for the transport sector, hydrogen will contribute to increased utilization of renewable energy sources. The need for energy storage will increase dramatically, and hydrogen will be the preferred option for large amounts of energy, and storage over longer periods.

Our partners include research institutions and industry, both in Norway and abroad.
The purpose of the planning and building legislation is to promote sustainable development in favor of individuals, the society and future generations. Together with the associated regulations and guidance, the Planning and Building Act is one of the most important framing factors for the Architecture, Engineering and Construction industry (AEC). The provisions of the legislation are implemented through governmental, regional and municipal planning and building administration, and put into practice by the professional actors in the building process.
The conversion of electric power by means of power electronics (converters) is playing an increasingly important role in various 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.
Pyrolysis of biomass has grown significantly as a research area the last decade. SINTEF carries out basic and applied research within pyrolysis of biomass for increased process understanding and production of upgraded fuels. We work together with both national and international industry and research partners to develop and improve value chains with pyrolysis oil or biocarbon (charcoal) as the main end product.
Because of world population growth, it is estimated that we must produce 70 % more food on the planet by 2050. In addition, it is necessary that we reduce greenhouse gas emissions dramatically. In this picture, it is important to preserve and utilize all the food being produced. One of the key elements is to gain control of the temperature immediately after harvest and capture, through processing and all the way to the end user. SINTEF Fisheries and Aquaculture is analysing, simulating, measuring and improving refrigeration systems to increase the benefit, increase product quality, reduce the negative impact on the climate, and to provide our customers with better profitability.
Future energy systems will include more production from renewable energy sources and increased consumer flexibility. At the same time future energy systems must be robust and reliable. ICT technology will increasingly be used to monitor, control and automate the grid.
Torrefaction is a thermochemical process for pretreatment of biomass. The treatment results in increased heating value and increased energy density (after compaction), lower grinding energy requirement, smaller particles and narrower particle size distribution after grinding and a hydrophobic nature of the solid product. The hydrophobic nature means that the solid product has much better water repelling properties, which makes it very resistant to biodegradation. Dry torrefaction is often referred to as a mild pyrolysis (200-300 ºC) process, which means that the thermal degradation occurs at relatively low temperature and at inert conditions. Wet torrefaction is also possible, where the biomass is heated in pressurized water. The pressure is high enough to keep the water in liquid form, and lower temperatures are needed compared to dry torrefaction. The additional benefits of wet torrefaction are the possibility to use very wet biomass as well as washing out water soluble ash elements.
The WtE sector is the backbone of the district heat network in Norway. However, WtE faces an array of challenges concerning process stability and energy efficiency, energy utilisation, environmental emissions (and carbon footprint), integration in future flexible energy systems, econimic aspects as well as public perception and regulative framework. SINTEF works on all those aspects both technically and at the value chain level.
Since the beginning of the eighties SINTEF has accumulated an extensive and versatile competence within development of small-scale heating technologies for the residential sector through solid biomass combustion, e.g. within pellets- and wood stove technologies.
