From Lab to Market: Evaluating Performance Metrics for Electrochemical Ammonia Synthesis versus Haber-Bosch

Ammonia (NH3) is a bulk commodity chemical known for its large production volumes and application in the global fertiliser industry, and is more recently being explored for its role as a sustainable energy vector. The industry standard ammonia production method is the century-old Haber-Bosch (HB) process, which is power by fossil fuels, and is...

Utilisation of Heat Released During the Production of Green Hydrogen Using Alkaline Electrolysis

To reduce greenhouse gas emissions and to limit global warming, fossil fuel based energy technologies need to be replaced by clean energy technologies. Renewable energy sources are dependent on weather conditions therefore security of energy supply is not ensured and the need for energy storage is growing. Hydrogen is considered a clean energy...

A 2D Modeling Study on the Heat Generation within Carbon Dioxide Electrolysis Systems for Different Geometries

An energy transition is needed in order to combat climate change. With the rise of intermittent renewable energy, a need for energy storage is also inevitable. Carbon dioxide electrolysis is a potential solution as CO₂emissions can be recycled and subsequently converted for energy storage. However, the technology is rather new and...

Effects of pressure on a sequential cascade system for electrochemcial CO2 reduction: A mathematical model and preliminary design

Within the electricity driven conversion methods, electrocatalysis has been assessed to be the closest to commercialisation. This can only be realised, if the system efficiency is increased in terms of the reaction rate, onset potential and/or selectivity. Current research has shown that, apart from the more widely investigated routes to improve...

Feasibility study of novel seasonal energy storage technologies for residential systems

The growing global energy demand and correlated rise in carbon emissions is forcing us to increase the use of renewable sources. The residential sector represents a large part of the total energy consumption, and European governments are investing in distributed PV to increase the renewable share in this sector. However, on top of the solar...

An Electrochemical Ammonia Synthesis Process: Process Model and Design of a Medium Scale Electrochemical Ammonia Production Plant

One of the greatest concerns of this century is climate change due to rising greenhouse gas emissions. The ammonia industry is responsible for 1.4% of the global CO2 emissions, thereby having a negative climate impact. However, ammonia is an essential ingredient in nitrogen fertilisers and is also considered as a potential energy carrier....
