Discover the sustainable path to decarbonization

Ecospray has mapped out a path towards the decarbonization of the Marine sector, with remarkable technologies and innovative approaches to achieving the IMO 2050 zero emissions target.

The Green Deal and Fit for 55 regulation frameworks are pushing the 2030 and 2050 deadlines closer.
Time, lack of clarity in regulations and a constantly changing landscape of new fuels and technologies are making decarbonization the most important priority and a crucial opportunity for Shipowners.

Ecospray is continuously working on decarbonization, following different ways:

  • Carbon negative fuel: with our biomethane liquefaction and CO2 recovery systems, we support the production of clean fuel from waste, agriculture and farming, transforming mobility;
  • Ship efficiency: our technologies for marine are connected with our digital platform One to help monitor performance KPIs, improving ship efficiency and fuel savings;
  • Carbon Capture: with our three diversified technologies – Carbon Capture with Amine and Calcium Hydroxide, Molten Carbonate Fuel Cells (MCFC) – we can efficiently capture CO2 from emissions based on shipowners needs and existing set-up.

Our Carbon Capture Solutions


This technology, based on amine chemical absorption, is conceived for CCS in marine onboard application. Widely used for land-based applications, Ecospray worked on the marinization of the technology, with the main goal of reducing the dimensions and complexity of the system. Considering the power consumption, another particular focus is the process optimization, using the thermal energy available on board.

CO2 is absorbed by the amine solution and, during the process, the amine solution is regenerated by stripping the CO2 out of it. Once separated, the CO2 is then liquefied and stored in specific cryogenic tanks onboard.


Calcium Hydroxide

The other solution is the CO2 adsorption with lime milk, a suspension of calcium hydroxide in water with a solid content ranging from 10% to 30%. Calcium oxide reacts with CO2 to form calcium carbonate, which is only slightly soluble in water, so it will form a solid product.
Particularly interesting in terms of capex and opex, this technology could fit for bulk carrier ships, which necessitates onboard storage of the chemical reagent in bulk, but it does have the advantage of not requiring CO2 storage on board.

Molten Carbonate Fuel Cells

The new generation of Molten Carbonate Fuel Cells (MCFC) combine high efficiency clean power generation and carbon capture in the same equipment. Other advantages of such solutions are negligible pollution and low maintenance as there are no moving parts in the fuel cell.
This technology can be also integrated with other Ecospray environmental solutions such as DeSOx, particle filters, and oxidation catalysts. Molten Carbonate Fuel Cells can be powered by methane (LNG, bio-LNG), hydrogen, ammonia, syngas and other fuels providing the reforming/cracking externally or directly inside the cell.


The CapLab laboratory was established jointly by Ecospray and the Department of Civil, Chemical and Environmental Engineering of the University of Genoa with the aim of developing electrochemical cells for CO2 capture, the production of energy and the promotion of the hydrogen carrier.

The new laboratory is focused on the development of molten carbonate fuel cells, a technology that allows the capture of carbon while producing energy, hence considered strategic in the context of the energy transition, precisely for its ability to capture CO2 from exhaust fumes and generate clean energy.

CapLab is the laboratory dedicated to the development of new technologies to promote decarbonization and energy transition, established jointly by Ecospray and the University of Genoa.

The technology in the R&D phase at CapLab allows, through fuel cells and electrolyzers, to capture the CO2 emitted from other processes and, as a secondary benefit, to produce energy, effectively promoting the transition to a CO2-free future.
