Abstract

Hydrogen is one of the transition energy sources and has an important role in the decarbonization of the global energy system. There are several methods of generating hydrogen such as reforming hydrocarbon, electrolysis of water as well as chemical reactions between active metals such as aluminum or primary hybrid solution. Hydrogen production from aluminum can provide an alternative way to produce hydrogen on demand. Hydrogen generator on demand is a generator that can produce hydrogen as needed, in other words the generator will only produce hydrogen when there is a demand. This research aims to design a hydrogen on demand generator with a more minimalist dropping mechanism to reduce blockage of aluminum powder so that it can overcome the weaknesses of the previous system. The method used in this research is the VDI 2221, which is a method with a systematic approach to solving problems and optimizing the use of materials and technology which is expected to facilitate a design. The result of this research is the design of a hydrogen on demand generator with a minimalistic dropping mechanism. From the results, it can be concluded that the VDI 2221 method is very helpful and facilitates of the design process and the realization of a hydrogen on demand generator design with minimalistic dropping mechanism, namely an automatic opening system supported by spring.
