Technical Field

The invention relates to the field of hydrogen production and application technology, in particular to a water pumping system for hydrogen production by methanol-water reforming.

Background

Among the numerous new energy sources, hydrogen energy will become the most ideal energy source in the 21 st century. This is because, in the case of burning coal, gasoline and hydrogen of the same weight, the hydrogen generates the most energy and the product of its combustion is water, without ash and exhaust gas, without polluting the environment; the combustion of coal and petroleum produces carbon dioxide and sulfur dioxide, which can produce greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously generate hydrogen and never use up.

There are over 1000 communication base stations in north america that are using fuel cells, which, although representing only a small fraction of the total communication base stations, clearly demonstrates that fuel cells have become an increasingly reliable source of energy for base stations in various locations, such as urban, suburban, rural, off-network, and environmentally sensitive areas.

The water pump using electric power is environment-friendly, low in cost and safe. However, in some remote areas there is no grid available. Furthermore, water pumps are used as equipment commonly used in construction sites, and these scenes are often not provided with these power grid infrastructures. The electric pump also has its own drawbacks.

Therefore, engineering technicians in the field need to develop a methanol-water reforming hydrogen production pumping system which is environment-friendly, low in cost, safe and suitable for remote areas, field construction sites and other environments.
