  Amongst the population of TeV gamma-ray sources detected with the High Energy
Stereoscopic System (H.E.S.S.) in the Galactic plane, clearly identified
supernova remnant (SNR) shells constitute a small but precious source class.
TeV-selected SNRs are prime candidates for sources of efficient cosmic-ray
acceleration. In this work, we present new SNR candidates that have been
identified in the entire H.E.S.S. phase I data set of the Galactic plane
recorded over the past ten years. Identification with a known SNR shell
candidate was successful for one new source, HESS J1534-571. In other cases,
TeV-only shell candidates are challenging to firmly identify as SNRs due to
their lack of detected non-thermal emission in lower energy bands. We will
discuss how these objects may present an important link between young and
evolved SNRs, since their shell emission may be dominated by hadronic
processes.
