In order to use effectively renewable energy Key words sources, we propose a new system, called Advanced Superconducting Power Conditioning System (ASPCS) that is Liquid hydrogen, SMES, renewable energy, fuel cell and composed of Superconducting Magnetic Energy Storage (SMES), electrolyzer, MgB superconductor. Fuel Cell-Electrolyzer (FC-EL), hydrogen storage and dc/dc and 2 dc/ac converters in connection with a liquid hydrogen station for fuel cell vehicles. The ASPCS compensates the fluctuating 1. Introduction electric power of renewable energy sources such as wind and photovoltaic power generations by means of the SMES having It is an urgent issue to reduce carbon-dioxide, and hence characteristics of quick response and large I/O power, and renewable energy, that is environmentally friendly, hydrogen energy with FC-EL having characteristics of moderate response and large storage capacity.
