Tai Chong Cheang Steamship (TCC), Hong Kong, and the University of Southern California (USC), the United States, have developed a new system for improving fuel efficiency and reducing Nitrogen Oxides (NOx) emissions. The technology uses tailored electrical nano-pulses to change the underlying chemistry, either at the point of exhaust or during combustion. The group’s experiments both in laboratories, and via a series of recent sea trials, consistently cut nitrogen oxide emissions at the point of exhaust by almost 90% and reduced particulate matter by up to 75%.
The dramatic improvement in efficiency was achieved using the radically different and more cost effective approach of nano-pulse power, compared to the standard scrubbers typically used on vessels that require training for crews and maintenance, said the researchers, who have also conducted tests using the same technology towards improving the combustion efficiency in marine diesel engines so that they can operate at their optimal continuous rating output.
