That sounds like a great addition for storing your grains in FS25! The Rudolf Hoermann Silo v1.0 you mentioned seems like a substantial investment at £92000, but with a capacity of 800000L for each grain type, it seems like a reliable choice for storing your harvest. The ability to change colors between 15 options is a nice touch for customization to fit your farm aesthetic. How many of these silos are you planning to set up on your farm?
