An energy generating system for a telecommunications facility includes a hydrogen fuel supply system. The hydrogen fuel supply system includes a source of liquid hydrogen which uses a high pressure expansion tank along with additional storage tanks. The system also incorporates first and second stage heat exchangers. The first stage exchanger is used to benefit from the endothermic reaction created when liquid hydrogen transforms into vapor. The cooling provided from this state change is transferred into a second medium which is delivered into a second stage heat transfer device and then used for air conditioning purposes. The system also includes a hydrogen generator which may be used to create AC power by combusting vaporous hydrogen.
