Water for the production of hydrogen and potable water can be from any source such as pond, stream, sea, well and even waste. The primary water is pumped to the plant and stored for processing of both the potable and distilled water. If there is a waste water component in the plant, it is separated and used only for creating distilled water for hydrogen production.
Very little water is needed for the creation of hydrogen gas. If potable water is to be provided to the community, a larger water source may be required.
