1. An H2 cycle for producing electricity with no accompanying carbon emissions, comprising a small modular nuclear reactor (SMR) as a heat source to drive the cycle, a Steam Generator to phase change water to steam using heat from the SMR, an Underground Coal Gasifier (UCG) to react this steam with in-situ coal to generate H2, Solid Oxide Fuel Cells (SOFCs) to generate electricity using the UCG-produced H2 as a fuel, and a recycle of the SOFCs' byproduct H2O back to the steam generator to repeat the cycle, where the cycle uses H2 as its working element, and wherein water supplied from the SOFCs to the Steam Generator is the sole water source for the cycle.
