Modelling Hydrogen in Power Systems: Optimisation for Investment and Operational Models

The energy transition is one of the major challenges of the 21st century, impacting the way energy is generated, conserved and consumed. Energy generation becomes more and more decentralised, intermittency and fluctuations suddenly are becoming topics of interest within day-to-day life and energy system operators are facing many new obstacles...

Electrified Conversion of Contaminated Water to Value: Selective Conversion of Aqueous Nitrate to Ammonia in a Polymer Electrolyte Membrane Cell

The application of a polymer electrolyte membrane (PEM) electrolytic cell for continuous conversion of nitrate, one of the contaminants in water, to ammonia at the cathode was explored in the present work. Among carbon-supported metal (Cu, Ru, Rh and Pd) electrocatalysts, the Ru-based catalyst showed the best performance. By suppressing the...

From wind to hydrogen: Technical design, analysis and economic study of a hydrogen production and transportation system powered by a nearshore wind farm

This research aims to design and analyse possible system configurations for a system in which wind energy from a Dutch wind farm, supplemented with electricity from the grid, is utilized to produce green hydrogen using an electrolyser, including options for transport of hydrogen to the consumer, and to perform an economic analysis on these...

PEM Electrolysis-Assisted Catalysis Combined with Photocatalytic Oxidation towards Complete Abatement of Nitrogen-Containing Contaminants in Water

Electrolysis-assisted nitrate (NO₃⁻) reduction is a promising approach for its conversion to harmless N₂ from waste, ground, and drinking water due to the possible process simplicity by in-situ generation of H₂/H/H⁺ by water electrolysis and to the flexibility given by tunable redox...

From solar to hydrogen energy: Modelling, design, and construction of a system for hydrogen production using photovoltaic panels.

<br/>Efficiency improvements of solar cells, growth in photovoltaic cells manufacturing, and declining prices of solar modules are just a few of the factors that have allowed solar power to break records (320 GW) in global cumulative installed capacity in 2016. In the energy systems of the future, solar energy will be the predominant energy...
