Hydrogen has long been proposed as a versatile energy carrier that could facilitate a sustainable energy future. For an energy economy centred around hydrogen to function, a storage method is required that is optimised for both portable and stationary applications and is compatible with existing hydrogen technologies. Storage by chemisorption in borohydride species emerges as a promising option because of the advantages of solid-state storage and the unmatched hydrogen energy densities that borohydrides attain. One of the most nuanced challenges limiting the feasibility of borohydride hydrogen storage is the irreversibility of their hydrogen storage reactions. This irreversibility has been partially attributed to the formation of stable dodecahydro-closo-dodecaborates (Mn=1,2B12H12) during the desorption of hydrogen. These dodecaborates have an interesting set of properties that are problematic in the context of borohydride decomposition but suggest a variety of useful applications when considered independently. In this review, dodecaborates are explored within the borohydride thermolysis system and beyond to present a holistic discussion of the most important roles of the dodecaborates in modern chemistry.

The instability of petroleum prices in the world market has caused the price of fuel in Malaysia to increase, especially in the transportation sector. As an alternative, the transition to use hydrogen as fuel was already in the study and research on the ability of hydrogen profit for internal combustion engine in the technical aspect. The governments involvement in the research as source of energy has been undertaken by several government agencies such as MOSTI, universities and automotive manufacturing industries. These agencies are responsible for developing activities, mainly for commercialization. The development of hydrogen energy in this country focuses on the role of hydrogen that includes methods of generating, transporting, storage, production, and long-term planning. Diversity in the use of hydrogen for Internal Combustion Engine (ICE) can be applied through many ways; hydrogen as the primary fuel, hydrogen mixed with gasoline, hydrogen mixed with diesel, and hydrogen mixed with NGV. Compatibility acceptance of ICE with hydrogen as an alternative energy can solve many technical problems such as backfire, knocking, and the reduction of hydrocarbon, carbon monoxide and smoke contaminants during engine ignition delay.
