Canjewar zuwa hydrogen sabu-sabu ta kama da adadin dabi’u da yunƙurin siyasa ta duniya

Sabuwar hydrogen sabu-sabu, da yawa a bayyana a matsayin maƙasar gaban don ƙare karbon mai zuwa a cikin sanadi da tafiya, yana da muhimman alaka da adadin dabi’u kamar neodymium, dysprosium, da terbium. Wadannan abubuwa suna inganta aiki na electrolyzers, fuel cells, da magnets mai ƙarfi a cikin fasaha na hydrogen. Amma samun wadannan adadi ke da wani babban shafi: karuwa 70% na samunsu da kusan 85% na gyara a duniya yana a Sin. Wannan dogaro yana bayar da matsalolin siyasa ga kasashe masu sayar da shi, kamar yadda aka nuna a cikin yunƙurin sayar da kaya da suka gabata ko yunƙurin da suka faru a cikin teku na Babban Ruwa da Myanmar.

Sakamakon binciken ya nuna cewa ƙaruwar farashin terbium ko neodymium zai iya ƙara farashin hydrogen sabu-sabu daga 5 zuwa 9%, yana sa wani irin ayyuka su zama ba su da amfani. Kasashe ba su da iya gyara adadi a cikin gida kamar su Afrika ta Arewa ko Yammacin Arewa, suna da matsalolin tsada da ƙaruwar farashi.
