Potentials of Hydrogen Technologies for Sustainable Factory Systems

Recent progress, trends, and new challenges in the electrochemical production of green hydrogen coupled to selective electrooxidation of 5-hydroxymethylfurfural (HMF)

“…This is a potential pathway to move factories towards carbon neutrality. 49 As an example, in 2018, the steelmaking factory consumed 3.75 GW h of energy from coal, which corresponds to 32.5% of the total coal consumption. 50 Therefore, the use of renewable energy in this industry will significantly reduce greenhouse gas emissions.…”

“…Due to the high volatility of power generation and the dynamically related interdependencies within a factory system, a valid technical, economic and environmental assessment of the benefits induced by H 2 technologies can currently only be achieved using digital factory models. 49 It is also necessary to improve the quality of the electrochemical production methods of H 2 and FDCA in large volumes to be scaled at an industrial and commercial level, optimizing the reaction media, and minimizing the energy costs of the production of FDCA (according to the materials of the electrocatalysts used). In order to guarantee both the circular economy and the decarbonization of the industry, it is interesting to study and evaluate the use of H 2 as a fuel to generate energy and/or heat on an industrial scale and use it, for example, in the same factories where bioplastics (PEF) are produced from FDCA.…”

Recent Advances in Nanoscale Engineering of Ternary Metal Sulfide-Based Heterostructures for Photocatalytic Water Splitting Applications

“…More importantly, the carbon-free nature of solar H 2 technologies can achieve the decarbonization of the energy sector, thus enabling a clean energy transition. 3,4 Among the solar-based technologies, photocatalysis is widely regarded as a prominent approach for H 2 production attributed to its inexpensiveness, simplicity, as well as its independence from wiring connections and external applied bias. 5−7 By utilizing renewable solar energy to split water molecules in the presence of semiconductor photocatalysts, solar H 2 is produced and potentially applied into fuel cell technologies for energy generation.…”

“…One of the pragmatic solutions is to utilize highly abundant solar energy and water to generate hydrogen (H 2 ) as a sustainable energy medium. More importantly, the carbon-free nature of solar H 2 technologies can achieve the decarbonization of the energy sector, thus enabling a clean energy transition. , …”

Economic Optimization of Local Australian Ammonia Production Using Plasma Technologies with Green/Turquoise Hydrogen

“…Table shows the technologies considered for both H 2 and NH 3 production at two levels of centralization which are national-scale plants and regional plants in state-wide farm areas. Data on steam methane reforming, − thermal plasma methane pyrolysis, − and water electrolysis to produce H 2 − were collected from the literature review. We also introduced in this article an oxygen credit of $1/kg of O 2 in case water electrolysis is applied for H 2 production, while a carbon credit of $1/kg carbon black (CB) will also be given to the scenarios where thermal plasma methane pyrolysis is used to produce turquoise hydrogen. − The price for $1/kg is conservative as typical carbon black prices are above $1.3/kg.…”
