Achieving room temperature superconductivity has always been the dream of mankind pursuing for a long time. Finding and synthesizing new materials with room temperature superconductivity is the ”Holy Grail” of condensed matter physics. Since the theoretical and experimental discovery of H3S and LaH10 with high superconducting critical temperature above 200 K, the hydrogen-based superconductors became the best candidate for achieving room temperature superconductivity, which is also one of the hot areas of multi-disciplinary research in physics, materials science etc. In this work, we outline the development history of superconductors, introduce several typical superconducting materials, focus on the current progress and challenges of hydrogen based superconductors under high pressures, discuss the design ideas of hydrogen based high-temperature superconductors in the middle and low pressure range, and look forward to the possibility of hydrogen-based superconductors with high critical temperature and even room temperature under low pressure or ambient pressure.

Key words: high pressure, hydrides, superconductivity
