Most Suitable Future-Proof Energy Supply for a New-Build Semi-Submersible Crane Vessel: Energy Transition-Compliant Energy Supply for Heerema's Sleipnir: A Multi-Criteria Analysis

Currently, our society faces a pressing challenge: global warming. The solution lies in the energy transition, which replaces fossil fuels with clean sources. This requires a global effort across all sectors, including shipping. While a significant portion of shipping relies on polluting fuels, the European Union’s Green Deal aims for climate...

An Ammonia-Fuelled Solid Oxide Fuel Cell - Internal Combustion Engine Hybrid System for Ships

Ammonia (NH3) may reduce CO2 emissions from the marine industry as it is carbon-free and more energy-dense than hydrogen or batteries. Pure ammonia exhibits poor combustion characteristics, so several researchers have already operated small-scale internal combustion engines (ICEs) with ammonia-hydrogen blends. However, nitrogen oxides NOx and...

Solid Oxide Fuel Cell Propulsion System Fueled by Ammonia: Subjected to a vessel from the Watertaxi Rotterdam Company

As a result of the Paris Agreement, energy technologies require to shift from fossil fuel based to carbon neutral. In 2015, the maritime sector was responsible for 2.6 % of the global CO2 emissions. The combination of the solid oxide fuel cell fueled by sustainable synthesized ammonia is seen as a potential solution to<br/>reduce emissions....

Selective Transport of NH₃ by Silica-Based Ceramic Pervaporation Membrane

Nitrogen (N) removal is one of the key tasks for every wastewater treatment plant under the growing pressure of environmental protection. Prevailing applied N treatment technologies are mostly energy-intensive. This dilemma triggers a rethinking of the way to approach N management. “N2kWh-From pollutant to power” is a project that aims at...

Electrodialysis with bipolar membranes for ammonia recovery in wastewater: An innovative concept for the treatment of ammonia residual streams

Municipal and industrial wastewater contains a significant amount of dissolved nitrogen. This is the results of the organic protein degradation and of the large employment of nitrogen (<i>N</i>), usually in the form of ammonia (<i>NH</i>₃), in the industry. Currently, nitrogen is removed in wastewater treatment plant (WWTP) by means...

Optimization of a fuel cell system running on ammonia from a wastewater treatment

The removal of nitrogen from wastewater is a costly and high energy demanded process. Not only in wastewater treatment facilities but also in the livestock sector nitrogen removal is costly. In this study the removal of nitrogen from wastewater by converting to ammonia to be fed as a fuel to a Solid Oxide Fuel Cell (SOFC) is treated. Ammonia is...
