Reliable Renewable Hybrid Energy Solutions
(SWEDES Centre, 2019)
- article
Worldwide studies, including the Paris agreement, show that it is necessary to reduce dependency on the non-renewable energy sources and fossil fuels such as oil and coal. Transition to renewable energy is evident, and ...
Thermal Response of Multiple Pipes and Fluids Using COMSOL for Geothermal Energy System Application
(NAUN, 2014)
- article
A geothermal system is modeled using COMSOL. The purpose is to study and evaluate the thermal response of the pipes and the fluids. The model is designed for a low energy network. A part of this network is used to collect ...
Statistical Investigation of Climate Change Effects on the Utilization of the Sediment Heat Energy
(MDPI, 2022-01-07)
- article
Suvilahti, a suburb of the city of Vaasa in western Finland, was the first area to use seabed sediment heat as the main source of heating for a high number of houses. Moreover, in the same area, a unique land uplift effect ...
Ecological governance in rural areas : Finnish approaches and practices
(Academic Journals, 2014-08-15)
- article
Along with the development of rural areas, rural ecological issues caused by inappropriate anthropogenic activities have not been drowned in the contexts of global environmental problems. The acceleration of rural development ...
Effects of sulphur on the storage stability of the bio and fossil fuel blends
(Estonian Agricultural University, Faculty of Agronomy, 2017)
- article
In this study, the aim was to find out if mixing two common fuels together could be beneficial for both the environment and storage stability of fuel. It is obvious, that adding biodiesel to fossil fuel will decrease its ...
Seabed Sediment as an Annually Renewable Heat Source
(MDPI, 2018-02-15)
- article
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, ...
Microalgae Chlorella vulgaris biomass harvesting by natural flocculant : effects on biomass sedimentation, spent medium recycling and lipid extraction
(BMC, 2018)
- article
Background: Microalgal biomass harvesting using traditional chemicals is costly for the production of biofuels, hindering the scale-up process of the technology. Thus, the search for a cost-effective microalgal harvesting ...
Analysis of ground heat exchanger for a ground source heat pump : A study of an existing system to find optimal borehole length to enhance the coefficient of performance
(World Scientific and Engineering Academy and Society (WSEAS), 2017)
- article
Ground Source Heat Hump is one of the emerging technic to utilize the reservoir of geothermal
energy in Europe. The crucial factor is to find the optimal length of the borehole to successfully design a heating system. The ...
Seabed sediment : a natural seasonal heat storage feasibility study
(Estonian Agricultural University, Faculty of Agronomy, 2017)
- article
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 ...
Evaluating heat current through concrete crush for heat storing application : a preliminary study using polynomial fitting for heat current curves
(IEEE, 2020-02-13)
- conferenceObject
The purpose of this paper is to study heat current through concrete crush as the crush is considered a possible material for heat storage. The heat current parameter is important for heat storages as it describes how ...
