1. A wind turbine rotor blade spacer for the transportation and storage of wind turbine rotor blades having a longitudinal axis and comprising a root end and a tip, and two halves bonded together forming an outer shell, the wind turbine rotor blade spacer comprising:
a guide adapted to guide a second blade assembly comprising a second blade which in turn comprises a second root end supported on a second root frame, with respect to a first blade assembly comprising a first blade which in turn comprises a first root end supported on a first root frame, the first blade assembly joined to the second blade assembly with a separation between the first blade assembly and the second blade assembly,
wherein the first root frame and/or the second root frame comprise a first width, the first width being measured in a direction perpendicular to a longitudinal axis of the first blade of the first blade assembly at a widest portion of the first root frame and/or the second root frame, respectively,
wherein the first root end of the first blade and/or the second root end of the second blade comprise a first diameter, wherein the first width is smaller than the first diameter.
