If there was a way for ships to drastically cut carbon emissions, comply with CII, EEXI, Fuel EU Maritime and have the opportunity to benefit from the EU ETS pooling mechanisms, without any significant alterations to engines or onboard systems, would the maritime world not be beating a path to the inventor’s door?
