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.

The International Maritime Organization (IMO) set as objective the reduction of CO2 emissions by 2030 by a margin of 40% compared to 2008. Recent studies showed that, according to the ships and the emission mitigation method applied, only 15–25% of CO2 reduction is de facto needed. Fuel cells represent an answer to meet this regulation. We propose two different solutions: (i) produce with SOFCs instead of engines the minimum power necessary to cut 20% of the emissions, or (ii) reduce the engine power of about 10% balancing the power requirement using MCFCs with CO2 capture. Using Aspen Plus each solution was investigated. The analysis contemplated LNG steam reforming to produce the H2 necessary for cell operation and the separation and liquefaction of CO2. Two case studies were considered comparing existing passenger ships with engines working on HFO and on LNG respectively. Although both...

Recently, a new and green method for carbon capture and sequestration in stable calcium oxalate from oxalic acid produced by carbon dioxide reduction was proposed. The reaction resulted in high-quality weddellite crystals. Assessing the stability of these weddellite crystals is crucial to forecast their reuse as solid-state reservoir of pure CO2 and CaO in a circular economy perspective or, eventually, their disposal. The thermal decomposition of weddellite obtained from the new method of carbon capture and storage was studied by coupling in-situ high-temperature X-ray powder diffraction and thermogravimetric analysis, in order to evaluate the dehydration, decarbonation, and the possible production of unwanted volatile species during heating. At low temperature (119–255 °C), structural water release was superimposed to an early CO2 feeble evolution, resulting in a water...

Le reacteur a granules est concu pour etre utilise dans le traitement de gaz industriels et permet de traiter des gaz industriels et d'eliminer des matieres particulaires desdits gaz tout en maintenant une efficacite constante. De plus, l'invention concerne un procede de traitement des agents polluants presents dans des gaz industriels au moyen dudit reacteur a granules et un reacteur a granules concu pour mettre en œuvre ledit procede de traitement.
