Contributions to the development of a strategy for the green hydrogen introduction into the energy system of the Republic of Croatia

S ciljem prilagodbe klimatskim promjenama donesen je Europski zeleni plan putem kojeg su propisane smjernice postizanja klimatski neutralne Europe do 2050. godine. Europska unija svoje je ambicije povećala gdje joj je cilj, do 2030. godine, smanjiti emisije stakleničkih plinova, u odnosu na 1990. godinu, za 55% (do sada je bilo 40%). Prilikom postizanja toga cilja, potrebno je smanjiti, odnosno potpuno ukinuti dobivanje energije korištenjem, a kao jedno od mogućih rješenja koje će u tom procesu pomoći predstavlja energija dobivena preko zelenog vodika. Sukladno time, prateći ambicije Europske unije, u ovom radu prikazana je projicirana potrošnja energije Republike Hrvatske do 2050. godine po svim sektorima. Uzimajući u obzir energiju dobivenu iz fosilnih goriva i deficit energije, proračunata je potrebna količina zelenog vodika za zadovoljavanje potreba u svim sektorima Republike Hrvatske. U konačnici, na temelju tih brojki, izračunata je snaga vjetroturbina i fotonaponskih modula preko kojih bi se proizvodila sva električna energija kao i snaga potrebnih elektrolizatora putem kojih bi se proizvodio sav zeleni vodik.The European New Green Deal, which gives guidelines for achieving a climate – neutral Europe by 2050, was adopted aiming to adapt to climate changes. The European Union has increased its ambitions with the goal to reduce greenhouse gas emissions by 2030., compared to 1990., by 55% (so far it was 40%). In achieving this goal, the energy production using fossil fuels must be reduced, i.e. eliminated, and as one of the possible solutions is the energy obtained through green hydrogen. Accordingly, following the ambitions of the European Union, this work presents the projected energy consumption of the Republic of Croatia until 2050. in all sectors. Taking into account the energy obtained from fossil fuels and the energy deficit, the required amount of green hydrogen was calculated to meet the needs in all the sectors of the Republic of Croatia. In the end, based on these figures, the required power of wind turbines and photovoltaic modules through which all the necessary energy is produced, as well as the power of the nedeed electrolyzers through which all green hydrogen would be produced, was calculated
