ADVANTAGESHydrogen gas may contribute effectively in reducing pollution in Jeju Island. Interestingly enough, hydrogen fuel cells in electric cars operate silently and much more efficiently than gasoline in energy produced for every given mass of fuel. They also offer 3 times the potency of fossil-based sources of fuel and does not cause harm to the health of humans compared to nuclear energy, therefore being ideal sources of fuel of aviation vehicles or space exploration space ships. Aside from astronomical applications, hydrogen fuel can be used in Jeju in electric cars or segways, thence reducing air pollution and noise pollution in Jeju Island.Conclusively, the settling of this project significantly cuts the costs of transporting not only chlorine gas(Cl2(g)), hydrogen gas(H2(g)), and a sodium hydroxide solution(NaOH(aq)), the products, but other heavy goods that need sufficient supply of these products such as building material and dry-cleaning and sterilising material. In addition, the number of rock salt deposits, although small, outnumber the whole of the mainland, providing wider access and supply to brine extraction/mining.DISADVANTAGE(S)Surely, limitations are inevitable. From groundbreaking to the establishment of the plant up and running, noise and air pollution will fill the nearby region. Simultaneously, organisms lose their habitats, and the order of ecology is to be disturbed and to some extent reorganised. This potential limitation can be resolved by sitting the plant in a deconstructed, formerly used-up area.The occupation of space is another problematic factor to the project. The storing of gas and liquid can occupy large spaces. To decrease the occupying space, we can integrate compression engineering of hydrogen and chlorine gas produced in electrolyzers, which produce, store, and utilize the products in an industrial-scale electrolysis process. Consequently, less volume will be required to store larger amounts of gas produced. Further, the storage of liquid can be placed underground to maximise the efficiency of space used. The supply of electricity is another setback to the efficiency of the plant. The standard grid electricity, supplied by power lines, are not the ideal source of electricity to perform electrolysis in an industrial scale. Hence, obtaining energy from renewable resources, like solar energy, ocean-wave energy, and wind energy, all of which are attainable especially in an island like Jeju, will allow for ideal running of industrial-scale electrolysis.ConclusionIn a macro perspective, the project ultimately contributes to the whole of South Korea and lengthens the longevity of Jeju island’s supply of natural resources along with its picturesque landscapes whilst achieving commercial profit. As aforementioned assertions have clearly evinced the advantages and exemplar solutions to the limitations the project may possess, the project must be accepted.
