As the reservoir for star formation, neutral hydrogen (HI) is an important ingredient in the assembly and evolution of galaxies. However, until recently, observations of HI were mostly restricted to z=0. With new radio facilities, including MeerKAT and the SKA, we can observe HI over billions of years of lookback time, incorporating HI into the observational census in a way not previously possible. I will show recent results from a large survey with MeerKAT, which take advantage of the increased sensitivity to probe fainter and more distant galaxies, providing useful benchmarks for simulations and new probes of galaxy environment.
