Short summary
Within the Cheap-GSHPs and GEO4CIVHIC projects, innovations were advanced in the field of ground heat exchangers design for shallow geothermal systems. Among these, a metallic type has been proposed that can be installed in direct contact with the underground. As carbon steel is prone to corrosion and corrosivity varies based on site-specific underground conditions, a laboratory assessment methodology was applied to metal samples to assess the corrosion rate and forecast the durability.
