High efficient hydrogen generation with green engergy powers

Abstract

A novel system and method for generating hydrogen by electrolysis of water from a green power source. Electricity generated by solar panel or wind mill is measured and connected with plurality of electrolysis stacks. The number of operating electrolysis stacks are constantly controlled by a controlling mechanism that calculates an optimal operating number of electrolysis stacks using the measured electricity parameter and the operating parameter of an electrolysis unit.

Description

CROSS-REFERENCE[0001]Priority is claimed from the U.S. Provisional Application No. 61 / 313,711, filed on Mar. 13, 2010, and the entirety of which is hereby incorporated by reference.DESCRIPTION OF RELATED ART[0002]The present application relates to a hydrogen generation system, and more particularly to a high efficient hydrogen generation system that adjusts to fluctuations and variations of the input power source, thus efficiently converting a green energy source into hydrogen fuel energy.[0003]Note that the points discussed below may reflect the hindsight gained from the disclosed inventions, and are not necessarily admitted to be prior art.[0004]Hydrogen has long been regarded as a clean fuel source alternative to fossil fuel energy sources. Hydrogen is non-polluting, transportable, storable, more efficient than petrol, and can be convertible directly to heat and electricity for both mobile and other applications.[0005]Hydrogen can be generated by a number of ways, the cleanest wa...

Problems solved by technology

However, traditionally wind and solar energies used in hydrogen electrolysis have inherent disadvantages that prevent them from being effectively and fully utilized.

Because their powers are intermittent and non-dispatchable, for example, when winds are strong, the output would be higher than power demands of a traditional electrolysis system, a great portion of generated energy would be wasted.

Because of this low conversion efficiency, producing hydrogen from water is of high cost, preventing hydrogen from being used as a fuel source of any significance.

However, this design dramatically increases the complexity in safety control of the elec
