An electricity generation system comprising electrical generation means (34, 35) that generates electricity from cryogenic fuels stored in tank (33). Power electronics system (32) conditions the electrical output of generation means (34, 35) to provide an output having a fixed voltage and frequency. Heat-exchanging means (37, 38) is arranged to cool electrical generator (35) and/or electronics system (32) by absorbing waste heat resulting from the electricity generating process and using this waste heat is to change the phase of the stored fuel to produce a gaseous fuel for use in turbine (34). The efficiency of electronics system (32) is increased by operating at the cryogenic temperatures present during the phase change of the fuel. Electrical generation means (34, 35) may comprise a fuel cell. |
