… in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the …
… of doing this were studied. Implementing variable condensation would reduce electrical usage by ca. 15300 kWh per year, which produces ca. 15600 kr of yearly savings. Furthermore, carbon dioxide emissions would decrease by 141 kg per year. Implementing a water cooled condensing …
… performance of the heat system. The electricity measurements show that several electrical loads are unbalanced and that the three phase cooling machines are not fully utilized. The factory is recommended to invest in a new kerosene boiler and a roaster boiler for combustion of …
… discussed.According to the modelling it takes 90 to 105 seconds to reduce the electrical outputfrom a power plant with CCS with one percentage point, depending on whichload the change is made from. A coal fired power plant without the CCS technologyis approximately eight times …
The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a …
… in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types …
The heating of companies premises is today functional with electrical heating and heating of fossil fuel. The energy cost for these kinds of heating in buildings has heavily increased during the last years and the influence on the environment has become more visual. This leads …
