Abstract

Hydrogen is an alternative energy that has a very abundant amount in nature, three-fourths of all elements in nature are hydrogen. Abundance can be developed because it can be converted into electrical energy and is expected to be able to replace fossil materials that are increasingly depleting in the future. For the management of hydrogen, a very safe storage is needed. One of the efforts by inserting hydrogen in certain metals. Magnesium is one material that is able to absorb hydrogen. But it has a disadvantage, namely the absorption and release time is very slow, this is due to the strong bond between hydrogen and magnesium. Several attempts have been intensively studied to improve the properties of Magnesium including the use of materials in the form of nanocrystals with Mechanical alloying techniques and efforts to add certain catalysts are now being actively studied. Research on the addition of Hematite (Fe2O3) catalysts to hydrogen storage materials has been carried out through Mechanical alloying techniques based on MgH2-Fe2O3. Hematite purely derived from nature has been successfully extracted chemically (precipitation method). The milled MgH2-Fe2O3 alloy samples were then analyzed by XRD and showed that the MgH2-Fe2O3 material was successfully reduced to the nanocrystal scale. The addition of catalysts and extended milling time also showed a decrease in desorption temperature.

Abstract

In the current era of the industrial revolution 4.0, the need for time, labor, and cost efficiency is a basic requirement for human life, especially regarding electrical energy sources. The supply of commercial electricity is still using electricity cables to deliver electricity to the load. Therefore, one of the ways of sending or transferring electrical power that continues to be developed today is wireless electricity transfer. The wireless transfer of electric power has several advantages compared to the use of cables, which can increase the convenience in the use of electrical equipment and can reduce the amount of electronic waste. This research will study the techniques or methods of near-field wireless energy transfer systems, namely the inductive coupling method, the magnetic resonance coupling method and the capacitive coupling method. The results of this study propose an optimal modeling of wireless power transfer so that results and quality are better, taking into account the distance between the sender and receiver because the work efficiency of wireless power transfer decreases with respect to distance. And the signal transmission frequency is low for inductive coupling, while the resulting frequency will be high on magnetic resonance coupling and capacitive coupling.
