Esikhathini esedlule, ubunzima bokuwa buye kwabangela amazwe ukuba amise izinhlelo zokusheshisa ukwakhiwa kwezimboni zenuzi futhi aqale ukuvala ukusetshenziswa kwazo. Kodwa ngonyaka odlule, amandla enuzi aphinde akhula.
Ngakolunye uhlangothi, ukungqubuzana kweRussia ne-Ukraine kuye kwaholela ekushintsheni kulo lonke uchungechunge lokuhlinzekwa kwamandla, okuye kwakhuthaza "abaningi abalahla izikhali zenuzi" ukuba balahle omunye ngemva komunye futhi banciphise isidingo esiphelele samandla endabuko ngangokunokwenzeka ngokuqala kabusha amandla enuzi.
I-hydrogen, ngakolunye uhlangothi, ibalulekile ezinhlelweni zokunciphisa imboni enzima eYurophu. Ukukhula kwamandla enuzi nakho kukhuthaze ukuqashelwa kokukhiqizwa kwe-hydrogen ngamandla enuzi emazweni aseYurophu.
Ngonyaka odlule, ukuhlaziywa kwe-OECD Nuclear Energy Agency (NEA) enesihloko esithi "Indima Yamandla Enuzi Emnothweni We-Hydrogen: Izindleko Nokuncintisana" yaphetha ngokuthi uma kubhekwa ukuguquguquka kwentengo yegesi yamanje kanye nezifiso zenqubomgomo iyonke, ithemba lamandla enuzi emnothweni we-hydrogen liyithuba elibalulekile uma kuthathwa izinyathelo ezifanele.
I-NEA iveze ukuthi ucwaningo nentuthuko yokuthuthukisa ukusebenza kahle kokukhiqizwa kwe-hydrogen kufanele kwandiswe esikhathini esimaphakathi, njengoba “i-methane pyrolysis noma i-hydrothermal chemical cycling, okungenzeka ihlanganiswe nobuchwepheshe be-reactor yesizukulwane sesine, ithembisa izinketho zekhabhoni ephansi ezinganciphisa isidingo sokuqala samandla sokukhiqizwa kwe-hydrogen”.
Kuyaqondakala ukuthi izinzuzo eziyinhloko zamandla enuzi ekukhiqizeni i-hydrogen zihlanganisa izindleko eziphansi zokukhiqiza kanye nokunciphisa ukukhishwa kwegesi. Nakuba i-hydrogen eluhlaza ikhiqizwa kusetshenziswa amandla avuselelekayo ngesilinganiso somthamo wamaphesenti angama-20 kuya kwangama-40, i-hydrogen ebomvana izosebenzisa amandla enuzi ngomthamo wamaphesenti angama-90, inciphise izindleko.
Isiphetho esimaphakathi se-NEA ukuthi amandla enuzi angakhiqiza ama-hydrocarbon aphansi ngesilinganiso esikhulu ngenani elincintisanayo.
Ngaphezu kwalokho, i-International Atomic Energy Agency ihlongoze umhlahlandlela wokusatshalaliswa kwezentengiselwano ukukhiqizwa kwe-nuclear hydrogen, futhi imboni ikholelwa ukuthi ukwakhiwa kwesizinda sezimboni kanye nochungechunge lokuhlinzeka okuhlobene nokukhiqizwa kwe-hydrogen yenyukliya kusesendleleni.
Njengamanje, amazwe amakhulu athuthukile emhlabeni aqhuba ucwaningo nokuthuthukiswa kwephrojekthi yokukhiqiza amandla enuzi, ezama ukungena emphakathini wezomnotho we-hydrogen energy ngokushesha ngangokunokwenzeka. Izwe lethu ligqugquzela ukuthuthukiswa kobuchwepheshe bokukhiqiza i-hydrogen kusuka kumandla enuzi futhi selingene esigabeni sokubonisa ukuhweba.
Ukukhiqizwa kwe-hydrogen kusuka kumandla enuzi kusetshenziswa amanzi njengempahla eluhlaza akukwazi nje ukubona ukuthi akukho kukhishwa kwekhabhoni ngesikhathi sokukhiqizwa kwe-hydrogen, kodwa futhi kwandise ukusetshenziswa kwamandla enuzi, kuthuthukise ukuncintisana kwezomnotho kwezitshalo zamandla enuzi, nokudala izimo zokuthuthukiswa okuvumelana kwezitshalo zamandla enuzi namandla avuselelekayo. Imithombo kaphethiloli yenuzi etholakalayo ukuze ithuthukiswe emhlabeni inganikeza amandla angaphezu kuka-100,000 angaphezu kwamafutha ezinsalela ezimbiwa phansi. Ukuhlanganiswa kwalokhu okubili kuzovula indlela yentuthuko esimeme kanye nomnotho we-hydrogen, futhi kukhuthaze ukuthuthukiswa kohlaza kanye nendlela yokuphila. Esimeni samanje, inamathemba abanzi okusebenza. Ngamanye amazwi, ukukhiqizwa kwe-hydrogen kusuka kumandla enuzi kungase kube yingxenye ebalulekile yekusasa lamandla ahlanzekile..
