Abstract

Pengembangan Thermal Energy Storage (TES) sebagai teknologi menyimpan energi panas untuk penghematan sumber daya listrik dapat ditingkatkan melalui optimasi komposisi material penyimpan panas. Logam magnesium merupakan material yang menjanjikan untuk digunakan sebagai media penyimpanan hidrogen dengan kapasitas tinggi dan biaya operasional yang efektif. Penelitian ini mengembangkan komposit Mg-Ni dengan variasi Ni untuk meningkatkan kemampuan penyerapan hidrogen. Serbuk Magnesium dengan ukuran 63 mikron diberikan penambahan Nikel dengan variasi 14, 15 dan 16 wt.% menggunakan proses ball milling dengan kecepatan 1000 rpm selama 3 dan 5 jam. Komposit Mg-Ni selanjutnya dilakukan pengukuran ukuran butir dan pengujian volumetrik dengan metode gravimetrik untuk mengetahui kemampuan penyerapan hidrogen. Hasil penelitian menunjukkan bahwa penambahan Nikel sejumlah  16 wt.% di dalam logam magnesium mampu menaikkan temperature dari magnesium hydride. Serbuk komposit hasil proses memiliki hidrogenasi unggul dan waktu penyerapan hidrogen relatif singkat dengan waktu ball-milling selama 5 jam.
