The Geological Survey of Finland (GTK) has published a map of hydrogen discoveries in the Finnish bedrock. According to the map, hydrogen has been found in groundwater in several locations across the country.
"Internationally, the discoveries are better than average when compared to similar types of rocks," said Teppo Arola, Senior Expert at the Geological Survey of Finland.
The finds indicate so-called natural hydrogen, which is produced in the bedrock by natural processes on its own, rather than through artificial means such as electrolysis, making a more efficient source of energy.
The hydrogen map below shows where the largest hydrogen discoveries have been made in Finland.
"The highest concentrations of hydrogen in groundwater have been found in Outokumpu, Nummi-Pusula in Lohja and Pori," Arola said.
In recent years, the world has realised that hydrogen can be sourced from bedrock deposits in such quantities that it could potentially be used as an energy source. This could be of great importance in the transition away from fossil fuels.
Hydrogen is a clean source of energy because it does not produce greenhouse gas emissions when burned.
Much of the hydrogen was mapped by the GTK using older surveys. For example, previous bedrock drilling measurements in search of other materials recorded how much hydrogen was located in a given area as part of the survey. These measurements were then compiled to create the GTK's new map.
