Green hydrogen is a promising energy vector for industrial applications. However hydrogen leaks can occur causing greenhouse effects and posing safety risks for operators and local communities potentially leading to legal liabilities. Industry 4.0 focuses on digital industrial modernization while Industry 5.0 emphasizes collaborative humancentered and sustainable processes. This study developed and analyzed an Industry 5.0 proof of concept as an a Read More

As the pursuit of greener energy solutions continues industries worldwide are turning away from fossil fuels and exploring the development of sustainable alternatives to meet their energy requirements. As a signatory to the Paris Agreement Australia has committed to reducing greenhouse gas emission by 43% by 2030 and reaching net-zero emissions by 2050. Australia’s domestic maritime sector should align with these targets. This paper aims to contrib Read More

Liquid hydrogen has the potential to significantly reduce in-flight carbon emissions in the aviation industry. Among the most promising aircraft configurations for future hydrogen-powered aviation are the blended wing body and the pure flying wing configurations. However their tapered and flattened airframe designs pose a challenge in accommodating liquid hydrogen storage tanks. This paper presents a design guide to tapered conformable pressure t Read More

Integrated energy systems (IESs) are essential for enabling the energy transition in communities and reducing CO2 emissions. This paper proposes a novel IES that combines photovoltaic (PV) and solar thermal energy with coordinated electrical and thermal energy storage to meet the energy demands of residential communities. The system also incorporates hydrogen production for fuel cell vehicles. A dual-objective optimization model was develop Read More

The long term and large-scale energy storage operations require quick response time and round-trip efficiency which is not feasible with conventional battery systems. To address this issue while endorsing high energy density long term storage and grid adaptability the hydrogen energy storage (HES) is preferred. This proposed work makes a comprehensive review on HES while synthesizing recent research on energy storage technologies and integration int Read More

Direct seawater electrolysis (DSE) has emerged as a compelling route to sustainable hydrogen production leveraging the vast global reserves of seawater. However the inherently complex composition of seawater—laden with halide ions multivalent cations (Mg2+ Ca2+) and organic/biological impurities—presents formidable challenges in maintaining both selectivity and durability. Chief among these obstacles is mitigating chloride corrosion and sup Read More

Electrolytic hydrogen from renewable sources is central to many nations' net-zero emission strategies serving as a low-carbon alternative for traditional uses and enabling decarbonisation across multiple sectors. Current stringent policies in the EU and US are set to soon require hourly time-matching of renewable electricity generation used by electrolysers aimed at ensuring that hydrogen production does not cause significant direct or indirect emissions. Wh Read More

With the rapid growth of photovoltaic installed capacity photovoltaic hydrogen production can effectively solve the problem of electricity mismatch between new energy output and load demand. Photovoltaic electrolysis systems pose unique challenges due to their nonlinear multivariable and complex nature. This paper presents a thorough investigation into the control methodologies for such systems focusing on both Maximum Power Point Tracking (MPPT) Read More

Hydrogen tanks (HT) with different connection modes are an integral part of the shipborne hydrogen fuel cell system. To ensure the safe and reliable operation of the shipborne multi-tank cascade system this study innovatively develops 3D models of four different connection modes for the shipborne multi-tank cascade system namely Type-22 Type-211 Type-121 and Type-112. Through computational fluid dynamics (CFD) numerical simulation the vari Read More

Green hydrogen is a promising solution within carbon free energy systems with Sub-Saharan Africa being a possibly well-suited candidate for its production. However green hydrogen production in Sub-Saharan Africa is not yet investigated in detail. This work determines the cost-potential for green hydrogen production within this region. Therefore a potential analysis for PV wind and hydropower groundwater analysis and energy systems optimization a Read More
