Kunyangwe sekuchengetedza simba remwaka kana vimbiso huru ye zero-emission aviation, hydrogen yagara ichionekwa senzira yakakosha yetekinoroji yekusarerekera kabhoni. Panguva imwecheteyo, hydrogen yatove chinhu chakakosha cheindasitiri yemakemikari, iyo parizvino inonyanya kushandisa hydrogen muGermany. Muna 2021, zvidyarwa zvemakemikari zveGerman zvakapedza 1.1 miriyoni matani ehydrogen, iyo yakaenzana ne37 terawatt maawa esimba uye zvikamu zviviri kubva muzvitatu zvehydrogen inoshandiswa kuGermany.

Maererano neongororo yakaitwa neGerman Hydrogen Task Force, kudiwa kwehaidrojeni muindasitiri yemakemikari kunogona kukwira kupfuura 220 TWH isati yatangwa kabhoni yekusarerekera tarisiro yazadzikiswa muna 2045. uye Biotechnology (DECHEMA) neNational Academy of Science and Engineering (acatech), yakapihwa basa rekugadzira mugwagwa wekuvaka hupfumi hwehydrogen kuitira kuti bhizinesi, manejimendi, uye vezvematongerwo enyika vanzwisise pamwe chete tarisiro inogona kuitika yehupfumi hwehydrogen uye matanho anodiwa kugadzira imwe. Chirongwa ichi chakawana rubatsiro rwemamiriyoni mana nemazana maviri emadhora kubva mubhajeti rebazi redzidzo yeGerman neKutsvagisa uye nebazi reGerman reEconomic Affairs uye Climate Action. Imwe yenzvimbo dzakafukidzwa nepurojekiti iyi indasitiri yemakemikari (kunze kwekunatsa), iyo inoburitsa anenge 112 metric matani ecarbon dioxide yakaenzana pagore. Izvi zvinotora chikamu che15 muzana chezvinobuda muGermany, kunyange zvazvo chikamu ichi chichitora chikamu chimwe chete kubva muzana chesimba rose rinoshandiswa.

Iko kusawirirana kuri pachena pakati pekushandiswa kwesimba uye kuburitswa muchikamu chemakemikari nekuda kwekushandiswa kweindasitiri kwemafuta ezvipfuyo sechinhu chakadzika. Indasitiri yemakemikari haingoshandisi marasha, oiri, uye gasi rechisikigo sezvitubu zvesimba, asi zvakare inopwanya zviwanikwa izvi sezvipfuyo kuita zvinhu, kunyanya kabhoni nehydrogen, kuitira kuti zvibatanidzwe zvakare kugadzira zvigadzirwa zvemakemikari. Aya ndiwo magadzirirwo anoita indasitiri zvinhu zvekutanga zvakaita seammonia nemethanol, izvo zvinobva zvazogadziriswazve kuita mapurasitiki uye marezeni ekugadzira, mafetireza nependi, zvigadzirwa zvehutsanana, kuchenesa nemishonga. Zvese zvezvigadzirwa izvi zvine mafuta ezvicherwa, uye zvimwe zvakatogadzirwa zvachose nemafuta ezvicherwa, nekupisa kana kupedza magasi egreenhouse anoverengera hafu yekubuda kweindasitiri, imwe hafu ichiuya kubva mukutendeuka maitiro.

Green hydrogen ndiyo kiyi kune yakagadzikana indasitiri yemakemikari

Naizvozvo, kunyangwe kana simba reindasitiri yemakemikari richibva zvachose kubva kune zvakagadzikana, raizongoita nepakati nepakati kuburitswa. Indasitiri yemakemikari inogona kudarika nehafu yekubuda kwayo nekuchinja kubva kufossil (grey) hydrogen kuenda kune inogoneka (yegirini) haidrojeni. Parizvino, haidhirojeni yave ichigadzirwa ingangoita kubva kumafuta efossil. Germany, iyo inowana inenge 5% yehydrogen yayo kubva kune inogona kuwanikwazve, mutungamiri wenyika dzakawanda. Pakazosvika gore ra2045/2050, kudiwa kwehydrogen kuGermany kuchawedzera zvakapetwa katanhatu kusvika pa220 TWH. Peak inodiwa inogona kunge yakakwira se283 TWH, yakaenzana ne7.5 times kushandiswa ikozvino.
