Actually, a gapped inductor stores most of its energy in the airgap
believe it or not. You can saturate a non-gapped inductor at quite a
modest flux level but the reluctance of the gap vastly increases
its storage ability. This technique is commonly used in SMPS chokes
where high energy storage requirements are the norm. The thing that
makes iron powder inductors a great choice in forward converters is
the inbuilt distributed airgap with a relatively small volume to
boot.
