The global energy demand is expected to increase by 30% within the next two decades. Plastic thermochemical recycling is a potential alternative to meet this tremendous demand because of its availability and high heating value. Polypropylene (PP) and polyethylene (PE) are considered in this study because of their substantial worldwide availability in the category of plastic wastes. Two cases were modeled to produce hydrogen from the waste plastics usi Read More

Hydrogen is increasingly recognized as a pivotal energy storage solution and a transformative alternative to conventional energy sources. This review summarizes the evolving landscape of global H2 production and consumption markets focusing on the crucial role of photothermal catalysts (PTCs) in driving Hydrogen evolution reactions (HER) particularly with regards to oxide selenide and telluride-based PTCs. Within this exploration the mechanisms of Read More

Hydrogen is set to become an important energy carrier in Germany in the next decades in the country’s quest to reach the target of climate neutrality by 2045. To meet Germany’s potential green hydrogen demand of up to 587 to 1143 TWh by 2045 electrolyser capacities between 7 and 71 GW by 2030 and between 137 to 275 GW by 2050 are required. Presently the capacities for electrolysis are small (around 153 MW) and even with an increase in el Read More

Due to its low NOx emission index the micromix burner technology is a promising alternative for using hydrogen in combustion. Various universities and research centers in Germany England and Spain have documented and studied this technology. However the number of studies on micromix burners is limited which hinders their implementation on an industrial scale. The present study aims to review developed works focused on micromix combus Read More

Hydrogen production has recently attracted much attention as an energy carrier and sector integrator (i.e. electricity and transport) in future decarbonized smart energy systems. At the same time power production is highly valued in energy systems as other sectors like transport and heating become electrified. This work compares two different low-emission systems to produce electricity hydrogen and heat. The proposed systems are based on chemical l Read More

Green hydrogen holds potential for decarbonizing the energy sector but high production costs are a major barrier. This study provides a comprehensive techno-economic-financial-environmental analysis of PV-based grid-connected hydrogen production plants targeting hard-to-abate industries having constant hydrogen demand across all Italy. Using real hourly data the Multi Energy System Simulator (MESS) an in-house developed rule-based tool was em Read More

This paper explores the current scope and direction of the emerging global governance of hydrogen within the broader context of the energy transition where technological innovation and institutional change intersect. Hydrogen as a critical yet complex energy vector requires coordinated governance efforts to navigate its development effectively. To this end we critically engage with key challenges facing the hydrogen sector and examine how institutio Read More

The lack of clarity and uncertainty about hydrogen’s role demand applications and economics has been a barrier to the development of the hydrogen economy. In this paper an optimisation model for the integrated planning and operation of hydrogen and electricity systems is presented to identify the role of hydrogen technologies and linepack in decarbonising energy systems improving system flexibility and enhancing energy system security and re Read More

Demand response (DR) is a crucial element in the optimization of integrated energy systems (IESs) that incor porate distributed generation (DG). However its inherent uncertainty poses significant challenges to the eco nomic viability of IESs. This research presents a novel economic dispatch model for IESs utilizing information gap decision theory (IGDT). The model integrates various components to improve IES performance and dispatch efficiency. With a foc Read More

The storage of excess electrical generation enabled through the electrolytic production of hydrogen from water would allow “load-shifting” of power generation. This paves the way for hydrogen as an energy carrier to be further used as a zero‑carbon fuel for land air and sea transportation. However challenges in hydrogen storage and transportation ultimately pose restrictions on its wider adaption along horizontal and vertical vectors. This pap Read More
