Ecospray is actively working on projects for carbon capture in the marine sector, using three different technologies for removing CO2 from exhaust gases: fuel cells, amines scrubbing and calcium hydroxide scrubbing. These different approaches can meet the requirements that are characteristic of different ship types, proposing specific solutions for each case to allow an effective retrofit and to be compliant with the limits imposed by IMO for the next years. The activity, partially carried out in collaboration with the University of Genoa, also led to the establishment of a new joint laboratory devoted to optimize fuel cell performance, while deadlines for onboard or prototypes in Ecospray laboratories are all fixed for middle 2022.
