Tensor networks are making rapid progress in the efficient simulation of open quantum systems with non--Markovian interactions with particle reservoirs or heat baths. One such scenario is quantum transport through impurities, where external reservoirs---the environment---drive particles through a junction region, which requires both a machinery to handle many--body interactions (tensor networks), a representation of the reservoirs, and a computational paradigm that properly embodies the physical scenario. I will discuss all three of these pillars of accurate simulation of many-body quantum transport, as well as current challenges and applications.
