Stakeholder and Techno-Economic Assessment of Iceland’s Green Hydrogen Economy
Mar 2025
Publication
Green hydrogen is a promising energy carrier for the decarbonization of hard-toabate sectors and supporting renewable energy integration aligning with carbon neutrality goals like the European Green Deal. Iceland’s abundant renewable energy and decarbonized electricity system position it as a strong candidate for green hydrogen production. Despite early initiatives its hydrogen economy has yet to significantly expand. This study evaluated Icela Read More
Expert Views on the Legitimacy of Renewable Hydrogen Certification Schemes
Feb 2025
Publication
In this article we draw on findings from a mixed-methods international survey of experts in the energy sector (n = 179) to better understand the role of legitimacy theory in informing the development of renewable hydrogen standards certification and labelling (SCL). The investigation is viewed through two conceptions of legitimacy: the sociological legitimacy of increasing the availability of renewable hydrogen technologies and the normative legitima Read More
A Novel Site Selection Approach for Co-location of Petrol-hydrogen Fuelling Stations Using a Game Theory-based Multi-criteria Decision-making Model
Feb 2025
Publication
Proliferation of co-located petrol-hydrogen fueling stations is an effective solution for widespread deployment of hydrogen as a transportation fuel. Such combined fueling stations largely rely on existing infrastructure hence represent a low-cost option for setting up hydrogen fueling facilities. However optimizing the layout of dual petrol-hydrogen fueling stations and their rational site selection is critical for ensuring the efficient use of re sources. Read More
Feasibility of Retrofitting a Conventional Vessel with Hydrogen Power Systems: A Case Study in Australia
Feb 2025
Publication
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
Optimization Research on a Novel Community Integrated Energy System Based on Solar Energy Utilization and Energy Storage
Feb 2025
Publication
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
Modulating Selectivity and Stability of the Direct Seawater Electrolysis for Sustainable Green Hydrogen Production
Feb 2025
Publication
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
