A project of fracture stimulation and secondary heat recovery from the metamorphic reservoir of the Larderello geothermal field could be developed in a next future. Geological and geophysical data suggest that the stimulation can enhance permeability and that the water injection can be recovered as steam. In particular, the area of the project is characterized by the presence of an important seismic reflector which has been explained assuming the presence of fractured rocks filled with high pressure fluids. Extensional and hydraulic fractures can present at temperatures of 300-350{degrees}C, and this makes the experiment of extreme interest.
