VTT: Finland explores crystalline bedrock for large-scale underground hydrogen storage
VTT and GTK have studied Finland's bedrock suitability for large-scale underground hydrogen storage. The research is part of Europe's growing renewable hydrogen production efforts.
VTT Technical Research Centre of Finland and the Geological Survey of Finland (GTK) have investigated the suitability of Finland's crystalline bedrock for large-scale underground hydrogen storage. This research is a key component of Europe's efforts to scale up renewable hydrogen production and ensure its availability.
The project specifically examined how underground storage impacts groundwater and bedrock. The objective is to identify safe and efficient solutions for hydrogen storage, which is essential for balancing production and consumption. The findings are expected to provide valuable insights for building future energy systems.
Finland possesses the potential to utilize extensive underground spaces for hydrogen storage. The research focuses on aspects such as how storage affects the physical and chemical properties of the bedrock and groundwater. Finland's geological conditions offer opportunities for constructing such facilities.
Successful underground hydrogen storage could, in the future, support the energy transition and reduce reliance on fossil fuels across Europe. The work by VTT and GTK lays the groundwork for developing this technology within Finland.
