Title:
HYDROGEN GENERATION AND CHEMICAL ENERGY STORAGE
Document Type and Number:
WIPO Patent Application WO/2023/220518
Kind Code:
A3
Abstract:
Two phased production of hydrogen involving an electrolytic cell containing first and second electrodes and a solution comprising a metal salt. The first and second electrodes are connected to an external electric energy source during a charging phase, which deposits the metal of the metal salt on the first electrode and evolves oxygen on the second electrode. Once the charging phase has been completed the first and second electrodes are disconnected from the external electric energy source with the cell containing the deposited metal kept in a standby condition until hydrogen production is required. During a discharging phase, the first and second electrodes are short circuited, whereby the metal is dissolved from the first electrode and hydrogen is evolved from the second electrode without any appreciable simultaneous withdrawal of electrical energy. The production of hydrogen is thereby increased accordingly. Variations of the above are also provided.
