As a technological niche, CHT represent an alternative to the currently dominating regime technology of diesel-powered trucks. For the successful growth of this niche, growing actor networks are considered a key element in the multi-level perspective (MLP) and strategic niche management (SNM). This paper shows that the actor network around the technological niche of CHT in Germany and Europe has grown and become denser since the initiation of the field trials in Germany but that some network bottlenecks remain.en303600presentation
