Shipbuilding giant HD Korea Shipbuilding & Offshore Engineering has unveiled its design of an ammonia scrubber for the upcoming generation of ammonia-fuelled vessels which will absorb toxic gas while emitting zero carbon.

At what the company dubbed a ‘Global Tech Forum’ for more than 100 clients at a pre-Posidonia meeting on Friday, HD KSOE showed off the new technology which it said reduces toxic gas emissions from ammonia fuel to nearly zero.
