Due to their weak nature, such as low inertia, offshore energy hubs are prone unprecedented fast dynamic phenomena. This can lead undesired instability problems. Recent literature, with main focus on onshore systems, suggests that electrolysers could be an attractive option support wind generators in the mitigation of balancing paper presents Electromagnetic Transient (EMT) model for real-time ...

Cross-linked quaternised Poly(2,6-dimethyl-1,4-Phenylene Oxide) (QPPO)-based membranes were prepared via Friedel-Crafts reactions using SnCl4 catalyst, 1,3,5-trioxane and chlorotrimethylsilane as environmentally-friendly chloromethylating reagents. New equations to calculate the degree of chloromethylation (DC) cross-linking (CLD) proposed. Ionic conductivity 133 mS cm?1 at 80 °C was obtained, ...

Contrary to traditional electrolysers which operate continuously at their nominal load, future alkaline need be able over a wide load range due the variability of renewable electricity supply. We have investigated how residual ripples from thyristor-based power supplies are influenced by operating system, and these affect efficiency electrolysers. For this, simulation tool was developed combine...

Wastewater can contain high amounts of ammonia which pose as a great safety threat if released into natural waters. The electrochemical oxidation offers viable strategy to remove concentrations and provides an attractive method for wastewater treatment. However, finding highly efficient low-cost catalyst is imperative overcoming the sluggish nature reaction. Herein, modified A- B-site perovskit...

Abstract Electrochemical CO 2 reduction reaction (CO RR) technology can reduce emission with converting excess electrical energy to high-value-added chemicals, which however needs further improvement on the electrolyser cell performance. In this work, extensive factors were explored in continuous electrolysers. Gold, one of benchmark materials for RR produce CO, was used as catalyst. Electrolys...

A multigeneration system based on solar thermal energy associated with hot and cold thermal storage is designed and analyzed energetically and exergetically. The system produces electricity, a heating effect, a cooling effect, hydrogen, and dry sawdust biomass as outputs by means of organic Rankine cycles, a heat pump, two absorption chillers, an electrolyser, and a belt dryer. The intermittent...

news & views the eventual transition to homogenous 3ʹ,5ʹ-linked genetic material. T echnologies for generating electricity from renewable resources, such as sunlight and wind, are on a steady trajectory of falling cost. Within the next decade, solar electric power is expected to reach grid parity, the point at which its cost will be equivalent (on a per-watt basis) to that of power generated fr...
