    A theoretical analysis of hydrogen-natural gas blends in slab tundish heating systems for green steel revolution
    (2025) Arat, Hüseyin Turan; Baltacioglu, Mustafa Kaan; Has, Seyit Mustafa
    The transformation of the iron and steel industry toward carbon neutrality is a global priority under Net Zero 2050 strategies and the European Green Deal. Recent investigations have emphasized that hydrogen–natural gas (H₂/NG) blending represents a technically feasible and near-term approach for the partial decarbonization of high-temperature steelmaking operations. This study theoretically investigates hydrogen-natural gas blending for tundish preheating in slab casting, with a focus on İSDEMİR, one of Türkiye’s largest steel producers. A fuel mixture containing 10% hydrogen and 90% natural gas by volume is evaluated in terms of energy equivalence, CO₂ emissions reduction, and economic feasibility. The analysis assumes continuous operation, negligible heat losses, and 100 % combustion efficiency to isolate the effects of hydrogen blending. The results indicate that a 10 % hydrogen substitution yields a 3.2 % reduction in CO₂ emissions compared with the pure natural gas process, which aligns with previous combustion studies reporting 3-5 % CO₂ mitigation for similar H₂ fractions. The required hydrogen is produced on site with solar photovoltaic (PV) powered polymer electrolyte membrane (PEM) electrolysis system, achieving a 6.2 year payback period, consistent with economic evaluations from the International Renewable Energy Agency and the IEA Hydrogen Review. Beyond its numerical outcomes, this study provides a strategic model for Türkiye’s Green Steel transition, aligning with national decarbonization goals and the EU Carbon Border Adjustment Mechanism (CBAM). Similar frameworks across Europe and the UK illustrate the compatibility of existing natural gas infrastructure with blended fuels. The İSDEMİR case exemplifies how conventional gas systems can be progressively adapted for hydrogen integration, offering a replicable framework for other steel plants in developing economies. Additionally, the safety aspects of the H₂/NG mixture, such as flame stability, flashback risk, and potential impacts on burner components and refractory materials, are highlighted as subjects for future investigation to support practical application.

    Electric vehicles and future of transport sector
    (CRC Press, 2022) Arat, Hüseyin Turan; Baltacioglu, Mustafa Kaan; Conker, Caglar
    Humankind lives in this last century where their habits and technology requirements have rapidly changed and evolved. The increasing unbalanced population and energy necessity have pushed researchers and technology-oriented argument owners into searching for different and more efficient energy sources. It has also updated its direction with the "electricity" option in the change of transportation technologies, which is the main cause of depleting oil resources and increasing emissions. For the last 50 years, vehicles used in transportation sectors (land, air, marine) adapted themselves either to hybrid or pure electrical power systems. Especially in the last 20 years, with an increasing trend and social favorable, the values and effects of "electric vehicles" (EV) have increased positively and have taken their place in the sector. In this book section, among the topics that the authors promised their readers, the state of the art and short history of EV technology, reasons for its emergence and development, advantages and disadvantages, technologies that evolved in its development process, and preliminary information about supply-demand situations and costs are given. In more detail, EV types, components, structures, topologies, hybrid EVs; battery EVs; fuel cell EVs differences and comparisons; battery and material technologies; energy efficiency; charging and filling stations/capabilities; control strategies, and reachable market data issues were covered. The last chapter of this book section, where recent works are mentioned in detail, is devoted to ideas about the future predictions of EVs in technology, environmental, and sociological terms. Since it is believed to be much more sustainable than oil and its derivatives with limited resources of electrical energy obtained in different ways and "near limitless", EVs will continue to use both in terms of performance, efficiency, and supply-demand trends over the next decades. Besides, transportation vehicles (ships, planes) that need "huge power" with the further development of materials and battery technology will tend to be electrified. As a result; in the energy family, EVs will be talked about more in the next century and will be the main subject in engineering life in terms of many types of research and products. © 2023 selection and editorial matter, Muhammad Asif.

    Experimental and theoretical fuel property comparison of four different waste biomass with a commercial counterpart
    (2025) Arat, Hüseyin Turan; Baltacioglu, Mustafa Kaan; Başar, Mustafa Tunahan; Doğan, Yaren
    The study focused on determining the fuel properties of apple pulp, pomegranate seeds, pomegranate peel and orange peel wastes to convert them into pellet fuel. The organic wastes were crushed and pressed into pellets, and solid fuel characterization process was conducted to analyze moisture content, ash content, volatile matter determination, fixed carbon content, total sulfur content, hydrogen content, lower heating value and higher heating values. The experimental analysis showed that the dry pomegranate seed pellet had 4244 kcal/kg, which was lower than the commercial pellet with 4759 kcal/kg calorific value under the same conditions. The moisture content of the commercial pellet and pomegranate seed samples were also different, with the commercial pellet having a higher moisture content at 5.42% compared to pomegranate seed samples at 1.83%. With low moisture content, production costs can be reduced and processing time can be shortened, making it easier to process low moisture samples than dry ones. Using organic wastes in the combustion process is also promising from an environmental and economic perspective.
