An improved emergency power system is disclosed for providing electrical power to a load such as a blowout preventer of a petroleum drilling apparatus. The improved emergency power system comprises a thermal battery having an anode and a cathode with a separator containing an electrolyte disposed therebetween. An internal heat layer is located in proximity to the separator containing the electrolyte. A squib is provided for activating the internal heat layer. The thermal battery remains dormant until the squib is energized to ignite the squib enabling the heat layer to render the electrolyte molten thereby activating battery to provide electrical power to the load. The squib may be energized remotely, mechanically or electrically.
