It focuses on sodium borohydride (NaBH₄) as a renewable hydrogen carrier. Prior study NaBH₄ regeneration methods using ball milling, which require Mg as a reducing agent, have not resulted in significant cost reduction of NaBH₄. Also in this study, Mg is considered to play an important role in the reduction reaction to NaBH₄. Therefore, we investigated a new regeneration method that can be processed at low temperature and low pressure and does not consume Mg by using the high chemical reactivity of plasma.
