Abstract

An apparatus, system, and method are disclosed for capturing electrical energy from a process designed for producing hydrogen. An electrode is placed within a stream of liquid alkali metal that flows through a titration module and interacts with water to produce, among other byproducts, hydrogen. Another electrode is placed within a reaction chamber that houses the water. The electrodes can then be coupled to a terminal, and during the hydrogen generation process (when the liquid alkali metal and water interact) the stream of liquid alkali metal acts as an anode and the electrode in the water as a cathode. Current flows, and energy is captured and made available as electrical energy at the terminal, which can be connected to electrical loads. The terminal may be connected with the terminal of a fuel cell that is consuming the hydrogen that is being produced, thus providing additional voltage and/or current.
