Seabed Sediment as an Annually Renewable Heat Source
Thermal energy collected from the sediment layer under a water body has been suggested for use as a renewable heat source for a low energy network. A prototype system for using this sediment energy was installed in Suvilahti, ...
Feasibility of New Liquid Fuel Blends for Medium-Speed Engines
(Molecular Diversity Preservation International (MDPI), 2019-07-20)
Several sustainable liquid fuel alternatives are needed for different compression ignition (CI) engine applications. In the present study, five different fuel blends were investigated. Rapeseed methyl ester (RME) was used ...
Kinematic viscosity studies for medium-speed CI engine fuel blends
(Estonian Agricultural University, Faculty of Agronomy, 2018)
Engine - driven power plants, run by diesel fuel or gas, will be needed for peaking power to keep the electricity grids stable when the production of renewable electricity, e.g. utilizing wind or solar power, is increased. ...
Seabed sediment : a natural seasonal heat storage feasibility study
(Estonian Agricultural University, Faculty of Agronomy, 2017)
The new discovery among renewable energy resources, seabed sediment, has been utilised as a heat source for 42 houses in Vaasa since 2008. Sediment heat is annually loaded by the Sun. In this study the amount of annually ...
Temperature measurements on a solar and low enthalpy geothermal open-air asphalt surface platform in a cold climate region
Solar heat, already captured by vast asphalt fields in urban areas, is potentially a huge energy resource. The vertical soil temperature profile, i.e., low enthalpy geothermal energy, reveals how efficiently the irradiation ...
