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...

Design of a Large-Scale Electrochemical CO2 Reduction Process

<br/>The rise of CO2 concentration in the atmosphere is a leading cause of global warming. Utilizing CO2 ob- tained from point sources, such as chemical industries, as a feedstock to produce high energy density fuels and chemicals could mitigate the emission of CO2 as well as provide various economic bene- fits. One promising technology is the...

Smart Home Energy Efficiency: Application of machine learning on smart meter power data to improve efficient electric energy usage in households

Nonintrusive Load Monitoring (NILM) can be used to disaggregate household energy<br/>usage collected from a central meter to the level of individual appliances, but has so far mostly been applied in controlled, small-scale settings. Further potential such as the application for energy efficiency classification and management have remained...

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....

A Decision Support Tool for Implementing District Heating in Existing Cities, Focusing on Using a Geothermal Source

In the context of climate change mitigation strategies in urban environments and reducing reliance on carbon-based energy sources, the Netherlands is gradually taking steps towards modification of its thermal energy system. Geothermal energy, widely used in agriculture, has recently emerged as a local, clean, and sustainable energy source able...

Fuel cell electric vehicle as a power plant: Fully renewable integrated transport and energy system design and analysis for smart city areas

Reliable and affordable future zero emission power, heat and transport systems require efficient and versatile energy storage and distribution systems. This paper answers the question whether for city areas, solar and wind electricity together with fuel cell electric vehicles as energy generators and distributors and hydrogen as energy carrier,...

A prediction method for the underwater acoustic signature of steel surface vessels, allowing for a quick approximation during the design stage.

This paper describes a prediction method for the contribution of the main onboard machinery to the underwater acoustic signature of steel surface vessels that can be used during the design stage. There are two reasons for the development of this method. Firstly, a small acoustic signature is important for naval and research vessels, due to...
