Ammonia - from pollutant to power: Removal and recovery of total ammoniacal nitrogen from residual waters for electricity generation

Ammonia (NH3) is one of world’s most-produced chemicals and is mostly used as a raw resource for fertilisers. From the used NH3-based fertilisers, almost half of the NH3 ends up in receiving water bodies, leading to eutrophication, eventually resulting in species diversity loss in the aquatic environment. To minimise environmental damage, total...

Combined gas engine-solid oxide fuel cell systems for marine power generation

Modern marine diesel engines operating on conventional marine fuels are unable to further reduce the adverse impact of ship emissions on the environment. Integration of a solid oxide fuel cell (SOFC) and internal combustion engine (ICE) equipped with an underwater exhaust (UWE) can provide the opportunity for mitigating ship emissions and...

Solid oxide fuel cells for ships: System integration concepts with reforming and thermal cycles

For decades, ships have been propelled by diesel engines. However, there are increasing concerns about their environmental impact. Fuel cells can provide an alternative to convert fuels directly into electricity, with high efficiencies and without hazardous emissions.<br/>Solid oxide fuel cells have a ceramic membrane, which functions at high...

Investigating nickel and ceria anode electrochemistry in multifuel environments

Conventional energy technologies and fossil fuels are causing irreversible damage to the environment. A transition from conventional to sustainable technologies is inevitable to address the environmental concerns. Solid oxide fuel cells (SOFCs) can play a key role in this transition because of their high efficiency and fuel flexibility – SOFCs...
