Energy demand and pollution problem, these both concepts linked to the fuel that our world wants for its survival. Improvements in technology and science in both aspects brought a number of ways to solve the situations. However, implementation on large scale is challenging for any government authority. If so these thoughts, in the minds of engineers and scientist drove them towards design a process that can produce hydrogen a clean fuel from water.
How many technologies are present for this process is unknown and even these processes do real work is a question part for many organizations. We know that hydrogen gives out water when burnt in air and do not affect the atmosphere. The energy obtained from it is so clean and pure. Nevertheless, to get hydrogen from water the process need more energy than what it gives out. Entropy is the factor, maybe.
For energy engineer and pollution control engineer this concept will be so interesting to do a project work in their academics. The idea needed for hydrogen production from water can give a better design. For instant designing a portable device, that develops hydrogen from water using solar energy that can installed on the roof of the house. The process of electrolysis, pervaporation, and membrane separation are some of the technologies that work for this science project.
An engineering model of photoelectochemical water splitting mechanism called as water photolysis absorb the sunlight and generate hydrogen and oxygen, need lots of research to establish it commercially.
Optimized energy balance will be the only criterion to judge the best process in competition. Designing an electrolytic cell is major equipment design in the project.
