In accordance with national climate and energy policy, GTK’s energy supply and environment segment promotes reduced dependence on imported energy supplies, low-emission modes of energy production and adjustment to the impacts of climate change. Energy research includes application of ground-based heating and cooling to larger structures, identification of stable sites for nuclear power plants and underground storage of spent nuclear fuel, as well as mapping of Finland’s vast peat reserves with a view to suitability as a fuel source and industrial usability. Studies of seabed geology generated reliable data on long-term climate and environmental changes through modelling of climate trends. The work is valuable in development of planning measures to adjust to climate change impacts.
Geoenergy is renewable energy stored in soil, bedrock and waterways. In Finland, most of this energy originates from the Sun and partly from the ground. Geoenergy can be utilised in heating and cooling buildings by using a heat pump. Planning and constructing a geoenergy system is a multi-stage project in which experts from different fields work in cooperation. GTK conducts geological and geophysical research to find out whether the target location is suitable for geoenergy production. GTK then uses the results from the field studies to accurately measure and model the energy field in order to create a durable and cost-efficient system.
