Abstract The conversion of electricity into hydrogen (H 2 ) gas through electrochemical water splitting using efficient electrocatalysts has been one the most important future technologies to create vast amounts clean and renewable energy. Low-temperature electrolyzer systems, such as proton exchange membrane electrolyzers, alkaline anion electrolyzers are at forefront current technologies. Their performance, however, generally depends on costs system efficiency, which can be significantly improved by developing high-performance enhance kinetics both cathodic evolution reaction anodic oxygen reaction. Despite numerous active research efforts in catalyst development, performance electrolysis remains insufficient for commercialization. Ongoing innovative an understanding catalytic mechanisms critical enhancing their activity stability electrolyzers. This is still a focus academic institutes/universities industrial R&D centers. Herein, we provide overview state directions H production. Additionally, describe detail technological framework production utilized relevant global companies. Graphical

Abstract Though first-generation biofuels threaten the world’s food supply, biomass-derived green hydrogen is becoming an alternative to conventional fuels. Rice straw (RS) a non-edible and good feedstock for producing because it has significant levels of carbohydrates, which are easily converted into fermentable sugars. Xylooligomers (XOS) most prevalent oligomers in hemicellulose can be obtained via chemical biological hydrolysis xylan. In this study, XOS were prepared from rice xylan (RS-based xylan) using modified acid process, produced XOS, specifically xylotriose (X 3 ), was used production cell-free synthetic enzymatic pathway (SythP) compared commercial X . This study reported first-time extracted RS-based The results showed great pattern upon addition 5 µl 4% sulfuric 2% xylan, followed by autoclaving at 121 °C 30 min. synthesized generate through water splitting 50 SythP. generation rates 2.948 2.68 mmol/l, respectively, energized , respectively. Accordingly, rate utilizing one slightly higher, confirms that made do not inhibit enzymes efficiently produce hydrogen. Consequently, lignocellulosic biomass synthesize valuable their further application as energy carrier promising sustainable approach (SythP).
