Thermal storage units that repair themselves

In the future, paraffin wax could help to make underground thermal storage units more durable. Such systems are used, for example, to store solar energy over a longer period of time. In a new study, geologists from Martin Luther University Halle-Wittenberg (MLU) investigated the extent to which paraffin wax can be incorporated into the shell of the storage tanks and whether this can prevent heat loss and close fissures. The research team reports on its findings in the journal PLOS ONE.
