AEA Technology is working with the Royal Navy to combat harmful diesel emissions. A new plasma system which could bring about substantial reductions in emissions of nitrogen oxide greenhouse gases (known as Nox) from ships is under test.
AEA’s Products and Systems business has been awarded a contract of approximately £1 million to produce a demonstration system one tenth the size required for a typical diesel generator used in a naval application. The Royal Navy has secured rights to use part of AEA Technology’s extensive portfolio of Electrocat intellectual property. This includes a range of plasma-catalyst technologies for exhaust emissions control.
The plasma system could help the world marine industry meet increasingly tough emissions regulations being proposed for the international maritime community. Initially, the AEA Technology system is being considered for use on future warships with indicative designs covering the full range of possible applications to include frigates, submarines, mine hunters and carriers where diesel generators that provide power release Nox. If legislation should necessitate retrofits, the Royal Navy has many ships that could benefit from the new technology, which is also equally applicable to diesel propulsion systems.
