Recent Advantages on Waste Management in Hydrogen Industry

Abstract

The turn to hydrogen as an energy source is a fundamentally important task facing the global energetics, aviation and automotive industries. This step would reduce the negative man-made impact on the environment on the one hand, and provide previously inaccessible power modes and increased resources for technical systems, predetermining the development of an absolutely new life cycle for important areas of technology, on the other. The most important aspect in this case is the development of next-generation technologies for hydrogen industry waste management that will definitely reduce the negative impact of technology on the environment. We consider the approaches and methods related to new technologies in the area of hydrogen storage (HS), which requires the use of specialized equipment equipped with efficient and controlled temperature control systems, as well as the involvement of innovative materials that allow HS in solid form. Technologies for controlling hydrogen production and storage systems are of great importance, and can be implemented using neural networks, making it possible to significantly improve all technological stages according to the criteria of energy efficiency reliability, safety, and eco-friendliness. The recent advantages in these directions are also reviewed.

Exploring the Role of Additives in Enhancing the Performance of Limestone-Based Thermochemical Energy Storage: A Review

“…As mentioned in the previous section, energy storage is crucial for maintaining a stable and reliable energy supply, especially as we integrate more renewable energy sources with intermittent generation patterns [20]. Energy storage technologies can be categorized into five types based on the process through which energy is stored: mechanical [21,22], electrochemical (or batteries) [23,24], thermal [25,26], electrical [26,27], and hydrogen storage technologies [28][29][30]. Figure 1 summarizes these types of energy storage technologies along with their sub-categories.…”

Effects of Copper(II) Oxide on the Co-Pyrolysis of Waste Polyester Enameled Wires and Poly(vinyl chloride)

“…The collection device consists of five bottle units. The empty bottle 1 ⃝ was set to cool and collect the pyrolyzed oil and prevent reverse suction. Bottles 2 ⃝ and 3 ⃝ were filled with 250 ml 0.1mol/L NaOH solution and were capable of collecting the chlorine-containing gases.…”

“…The peak areas of chloride ions in standard solutions with concentrations of 0.00005, 0.00025, 0.0005, 0.0025, and 0.005 mol/L were obtained according to the peak height of chloride ions in the chromatograms, as summarized in Table 1. A linear regression line of chloride ion concentration and peak area was fitted as shown in Figure 2, with its regression equation shown in Equation (1), and the fitting correlation coefficient was up to 0.9989, implying a high correlation and high confidence of the fitted curve. y =( 11198 ± 181)c − (0.545 ± 0.455)…”

“…Thermal processing via pyrolysis is widely used to solve problems involved with plastic waste [ 1 ]. For example, pyrolysis is demonstrated to be a promising technology for recovering copper via removing the polymer paint of waste enameled wires [ 2 ].…”

The Cost Reduction Analysis of Green Hydrogen Production from Coal Mine Underground Water for Circular Economy

“…Hydrogen can be produced from both renewable and non-renewable sources. Global hydrogen production in 2020 will rely almost entirely on fossil fuels [9,10]. Commercial hydrogen production is currently based primarily on steam reforming of natural gas and partial oxidation of coal.…”
