TY - GEN AB - Majority of the present-day technology for production of hydrogen utilizes Electrolysers, which are energy intensive and with a large carbon foot print. In order to provide a cost effective and efficient production process, Green Keplerate Laboratory, at Banaras Hindu University (BHU) in India has developed a novel and sustainable Quantum-derived technology for the bulk production of Solar Green Hydrogen from water through cost-effective photocatalytic based process. This team at BHU, led by Dr. rer. nat. Somenath Garai, has designed a Quantum Confinement Technology, wherein the confinement of the reaction systems inside the space with sub-Bohr radius, leads not only an accelerated kinetics but also alters the overall thermodynamics of the reaction. The Quantum Thermodynamics will reign inside the compartmentalized Quantum Containers, also amounting for the unusually high photo-conversion-efficiency. This team has effectively simulated the industrial waste material-based electron donor system and through progressive upgradation of the prototypes (from generation-I to generation-III), they have ultimately accomplished the optimum green H2 generation rate, with a peak production rate of approximately 50 Litres/hr (YouTube Link for Lab-Scale Demonstration: https://youtu.be/uIKdd_5Uzfw). Similarly, they have rigorously tested their technology with saline water, simulated seawater and even artificially polluted water. The team is confident that with abundance of sea water in the maritime domain, they can cost effectively directly harness sea-water for green hydrogen production, subsequently employing it as a marine and naval fuel, representing a promising and eco-friendly technological endeavour. In addition to the pure solar energy as an input to this process, the team has also demonstrated production of hydrogen with LED lights as an input, should there be a challenge in availability of direct sunlight in certain circumstances such night time or poor weather conditions or inside closed compartments. The team has ensured that the design and assembly of the production unit is carried out in such a manner that they can produce hydrogen with maximum purity, thereby alleviating the need for additional purification. Hydrogen thus produced can be directly injected into the IC Engines, which they have successfully demonstrated in a two-wheeler, portable power generators and recently in river boat (https://youtu.be/-jLBpJ3GOHk). They have also successfully adapted the legacy IC Engines, by suitably redesigning the fuel manifold system, adhering to the safety standards, to power the river boat. Notably, the legacy of hydride storage free IC-Engines with minimum modifications have been shown to run on the pure hydrogen produced with this new technology. These engines powered by green hydrogen minimizes energy loss due to heating, thereby elevating performance and durability. In view of the above experiences, the authors feel that this technology can be utilized in the marine and naval sectors. This paper begins with the introduction to the modern Quantum technology application for green routes of energy generation and will discuss the challenges (safety, storage, metal-embrittlement etc.) and the mitigating solutions for adapting to the marine/naval sector.
