The aim of the present study is to assess techno-economic viability integrating biomethanation into power gas systems in a real waste water treatment plant (WWTP). research first attempt several scenarios based on technology that include both in- and ex-situ as well utilisation on-site renewable electricity grid transient mode. Five were designed evaluated calculated LCOE lies between 127.8 159...

More abundant and economically friendly Sr-doped praseodymium ferrites show an increase in the electrocatalytic activity as amount of Sr dopant increases that is linked to increasing concentration oxygen vacancy.

Chromium poisoning of the air electrode is a primary degradation mechanism for solid oxide cells (SOCs) operating under fuel cell mode. Recent experimental findings show that reversed pulse operation SOCs operated as electrolyser can reverse this and extend lifetime. Here, we use multiphysics model an SOC to investigate effects alleviating chromium electrode. We study time fraction electrolysis...

The co-electrolysis of CO2 and H2O at an intermediate temperature is a viable approach for the power-to-gas conversion that deserves further investigation, considering need green energy storage. commercial solid oxide electrolyser promising device, but it still facing issues concerning high operating temperatures improvement gas value. In this paper we reported recent findings simple have sugge...

Massive investments in offshore wind power generate significant challenges on how this electricity will be integrated into the incumbent energy systems. In context, green hydrogen produced by emerges as a promising solution to remove barriers towards carbon-free economy Europe and beyond. Motivated recent developments Denmark with decision construct world's first artificial Offshore Energy Hub,...

In the established technologies, use of classic depressants pyrite, such as lime represents one main problems in flotation gold-bearing copper (Cu) ores. Lime addition leads to depression noble metals - gold (Au) and silver (Ag) that end up tailings. Thus, operator incurs economic losses. The current paper presents research aimed at replacing pyrite ore, bearing silver, classical depressor with...

H2 production from solar electricity in the region of Atacama Desert – Chile has been identified as strategical for global hydrogen exportation. In this study full supply chain investigated 2018 and projected to scenarios 2025-2030. Multi-year hourly electrical profiles data have used real operating PV plants simulated Concentrated Solar Power “CSP” with Thermal Energy Storage “TES” well commer...
