		| Abstract: | 
		Large inhomogeneities in neutral hydrogen in the universe can be detected at redshifts z <= 10 using the redshifted 21cm line emission from atomic hydrogen. This paper reviews the expected evolution of neutral hydrogen and presents estimates for future surveys of HI at z ~3. We also discuss the possibility of detecting neutral hydrogen at higher redshifts. |
