Abstract

Biovodik (bioH2) je vodik proizveden održivim i ekološki prihvatljivim biološkim procesima koji uključuju mikroorganizme poput bakterija i algi. Jedan od najpoznatijih bioloških procesa za proizvodnju bioH2 je fermentacija. Tijekom fermentacije bakterije razgrađuju organsku tvar (šećer ili celuloza) u anaerobnim uvjetima proizvodeći pri tome bioH2 kao metabolički nusprodukt. Sama proizvodnja bioH2 privukla je pažnju kao potencijalni obnovljivi izvor energije jer se bioH2 može proizvesti iz organskih materijala poput poljoprivrednog otpada, otpadnih voda ili biomase. Obzirom na način proizvodnje, bioH2 se smatra čistim i održivim izvorom energije što ga čini konkurentnim tradicionalnim izvorima energije. BioH2, uz to što se može koristiti kao gorivo, je i vrijedna sirovina u proizvodnje električne energije, pročišćavanju vode te proizvodnji amonijaka i gnojiva, sinteze metanola i polimera, rafiniranju nafte (hidrokreking i hidroobrada), proizvodnji farmaceutika itd. U okviru ovog završnog rada napravljen je literaturni pregled bioloških procesa proizvodnje bioH2 kao obnovljivog i alternativnog izvora energije.

Abstract (english)

Biohydrogen (BioH2) is hydrogen produced by sustainable and environmentally friendly biological processes involving microorganisms such as bacteria and algae. One of the best-known biological processes for BioH2 production is fermentation. During fermentation, bacteria break down organic material (such as sugar or cellulose) under anaerobic conditions, producing BioH2 as a metabolic byproduct. The production of BioH2 has attracted attention as a potential renewable energy source because it can be produced from organic material such as agricultural waste, wastewater, or biomass. Because of the production method, BioH2 is considered a clean and sustainable energy source that can compete with conventional energy sources. In addition to its use as a fuel, BioH2 is
a valuable resource for electric power generation, water treatment, ammonia and fertilizers production, methanol and polymer synthesis, petroleum refining (hydrocracking and hydrotreating), pharmaceutical production, and more. This final thesis includes a literature review of biological processes for the BioH2 production as a renewable and alternative energy source.
