Engineers Perfecting Hydrogen-Generating Technology

The engineers are researching on the production of hydrogen by adding water to an alloy. The Purdue researchers are thinking of ways to create particles of the alloy that could be positioned in a tank such that they react with water to produce hydrogen on demand. This technology makes use of water which is added to the alloy of aluminium and gallium; thus, producing hydrogen gas. Professor Jerry Woodall, the brain behind the whole process stated that gallium is used because it prevents oxidation from occurring. The storage and transport of hydrogen is not necessary in this case due to the generation of hydrogen on demand. Acquisition of raw materials, aluminium and gallium, is not of an issue as both can be easily and cheaply obtained. This is useful for large scale production of this technology. Continuation of this research has produced an alloy that gives a more efficient reaction, liberating hydrogen at a faster rate. This technology has the potential to apply in various aspects of our life, such as in vehicles or for commercial use. Hydrogen can be used to run internal combustion engines or even submarines as soon as the technology has been fully developed. The emission of water from the usage of hydrogen is a plus factor for the technology to be fully internalized into our daily life. The Purdue researchers discovered that making the process competitive with conventional energy sources, would require alumina to be recycled back into aluminum using a dedicated infrastructure. However, the recycling of the alumina using the current technology would cost less. The researchers mentioned that further research has to be done to improve the alloy. Furthermore, develop systems for the controlled delivery of hydrogen needs perfecting.
