SINTEF is performing research on the whole battery value chain, from development of new materials for existing batteries and new battery systems to evaluation of performance and lifetime of commercial batteries for various applications. Other electrochemical energy storage systems such as supercapacitors and redox flow batteries are also areas of research.
Building and infrastructure Energy efficiency and renewable energy
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.
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.
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.
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.
The HTL conversion process occurs in liquid phase, with water used as the reactive medium. During the process, the feedstock decomposes forming solids, a liquid phase, consisting of aqueous and oily streams and a small amount of gas. It is ideal for processing wet biomass since large thermal energy savings can be achieved by avoiding the drying step that is required in conventional thermal processes. Moreover, the energy used to heat up the feedstock in the HTL process can be recovered effectively from product streams. This leads to high energy efficiencies from raw feedstock to the biocrude of the HTL step.
SINTEF Energy Research is a 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 Energy Research is preparing new and integrated energy systems for commercial building complexes with the aim of reducing both energy consumption and operational and investment costs.
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.
Transport is crucial to the society. Freight transport provides citizens and businesses with the goods, and free mobility for persons is a human right in most countries. However, transport has significant negative effects like pollution, causalities, space consumption, reduction in urban life quality, etc. ICT applied in infrastructures, vehicles, fleet management, user applications and traffic management can mitigate the negative effects and facilitate sustainable transport.
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.
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.
