In both the private and public sectors, green hydrogen is treated as a promising alternative to fossil energy commodities. However, building up production capacities involves significant carbon production, especially when considering secondary infrastructure, e.g., renewable power sources. The amount of required capacity well involved calculated in this article. Using Germany an example we show...

Hydrogen has received substantial attention because of its diverse application in the energy sector. Steam methane reforming (SMR) dominates current hydrogen production and is least expensive endothermic reaction to produce grey hydrogen. This technology provides advantages low cost high efficiency; however, it emits an enormous amount CO2. Carbon capture storage (CCS) helps reduce these emissi...

ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...
