“…This energy input eliminates the need for additional external energy sources, such as electricity or fossil fuels, making the process more sustainable and cost-effective. Moreover, the carbon dioxide present in flue gas can act as a reactant in the production of high-quality charcoal, further enhancing the efficiency of the process [4]. The integration of flue gas as an energy source for charcoal production offers several environmental benefits.…”

This research suggests a unique way to produce charcoal utilizing industrial flue gas as an energy source. The process entails gathering, cleaning, and transporting the flue gas to a pyrolysis reactor where it is used to carbonize and heat biomass. The paper outlined the design of various components, such as the heat exchanger, pyrolysis reactor, and flue gas filter. It specified that the flue gas temperatures in the glass, pulp and paper, and alcohol industries typically range from 400-500°C, 200-500°C, and 150-300°C, respectively. Furthermore, the chemical compositions of these industries were analyzed at the factory. The study emphasized the importance of these design considerations and temperature ranges for efficient operation and optimal performance in the respective industries. The resultant charcoal has several uses and is a sustainable and renewable fuel. In addition, the technique lessens greenhouse gas and flue gas emissions into the atmosphere, protecting the environment and slowing down climate change. The average chemical composition of flue gas from three industries was ascertained, together with the temperature range necessary for pyrolysis and the mechanical layout of the system used to produce charcoal. Upon determining the characteristics of industrial flue gas, the mechanical design of the charcoal production process was incorporated essential components. These include a temporary storage tank, a pyrolysis reactor, and a flue gas filter. This comprehensive design aims to ensure the production of quality charcoal while addressing environmental concerns related to pollution from flue gas treatment. The integration of these components is crucial for optimizing the production process and enhancing environmental sustainability by mitigating the impact of flue gas emissions on the environment. The project report emphasizes the significance of these design considerations in achieving efficient and environmentally friendly charcoal production. The paper also discusses the environmental and economic benefits of using flue gas as an energy source for charcoal production. The paper concludes that this method is a feasible and promising solution for efficient resource utilization and sustainable development.

Hydrogen plays an essential role in the energy‐transition process. Even though currently almost 80–96% of hydrogen is produced from fossil fuel sources in the world, the exciting feature of hydrogen is that it can be produced from renewable sources by splitting water molecules through electrolyzing, and then it can be re‐electrified without any emissions by‐products. Hydrogen is the secondary source of energy as well as an energy carrier that stores and transports the energy produced from other sources such as water, biomass, and fossil fuels. It is a clean‐burning fuel; when oxidized in a fuel cell, it produces heat, electricity, and water vapor as a by‐product, without any carbon emissions. Despite these exciting characteristics of hydrogen, there are still a variety of challenges, such as cost‐effective hydrogen production and its technological challenges, storage, safety, transportation, and cost issues. This article aims to overview the challenges and opportunities in hydrogen production, storage, and transportation along with some future perspectives on hydrogen.

In this paper, mixed integer nonlinear programming (MINLP) optimization algorithm integrated with kriging surrogate-model is newly formulated to optimize the dispersion characteristics of photonic crystal fibers (PCFs). The MINLP is linked with full vectorial finite difference method (FVFDM) to optimize the modal properties of the PCFs. Through the optimization process, the design parameters can take real and/or integer values. The integer values can be used to selectively fill the PCF air holes to control its dispersion characteristics. However, the other optimization techniques deal with real design parameters where the PCF can be optimized using none or predefined infiltrated air holes. The MINLP algorithm is used to obtain an ultra-flat zero dispersion over a broadband of wavelength range from 1.25 to 1.6 μm using silica PCF selectively infiltrated with Ethanol material. To show the superiority of the proposed algorithm, nematic liquid crystal selectively infiltrated PCFs are also designed with high negative flat dispersion over wide range of wavelengths from 1.25 to 1.6 μm for the quasi transverse magnetic (TM) and the quasi transverse electric (TE) modes. Such designs have negative flat dispersions of − 163 ± 0.9 and − 170 ± 1.2 ps/Km nm, respectively over the studied wavelength range. Therefore, the MINLP algorithms could be used efficiently for the design and optimization of selectively filled photonic devices.
