… energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest. Today's existing plants are mainly in Europe and particularly in Germany. These …
… of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system. The purpose of the Master’s thesis is therefore to explore the economic and technical potential for a seasonal heat storage in Tekniska verken’s energy …
… this master thesis has been to investigate if geothermal energy storage with a seasonal storage of heat and cold can be applied within Löwenströmska hospital’s property area using groundwater modeling. A hydraulic groundwater model was constructed in MODFLOW based on a …
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In …

… production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated. What affects the price …
The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk …
en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
… Supply chains with terminal chipping has the ability to meet fluxes due to seasonal changes, bad weather and it to minimise road damage during thawing of frozen gravel roads. A supply system based on a combination of 75 % of the yearly demand from the cheapest supply chain and …
En studie om solvärme med säsongslagring
… if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?
… too much electricity is generated. The spillage can be avoided with modified seasonal planning. There is no seasonal planning in the model since the model only simulates over one week. In the model export of electricity is assumed to be possible, a large wind power generation …

… To be able to do that a simulation were made in NetSim based on different seasonal basis. The results showed that a prosumer does not affect the network in a noticeable way. However, during the summer months, the district heating network already has excess heat due to the use of …

… SMHI (The Swedish Meteorological and Hydrological Institute). The spatial and seasonal variation of snow cover was investigated for the winter seasons from 1999 to 2010. A GIS model was created where the need of plowing was estimated for the logging residue landings within the …
… AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather …
… while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content. The mills have some listed quality criteria, which have to be fulfilled by growers before wheat of bread-quality can be transported to the mills. These …
