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 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 and our Smart Scrubber are powered by AI to help monitor performance KPIs, improving ship efficiency and fuel savings

  • Carbon  Capture: with our three diversified technologies -Fuel cells, Carbon Capture with and Calcium Hydroxide Lime milk – we can efficiently capture CO from emissions based on shipowners needs and existing set-up.

Our Carbon Capture Solutions


Ecospray is developing an amine absorption technology for CCS in marine onboard application. This solution is widely used for land-based applications and Ecospray is now working on the marinization of the technology, keeping an eye on monitoring the reduction in energy consumption.
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

Another approach Ecospray is studying 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. The suspension of calcium carbonate is harmless for the marine environment; indeed, limestone is a constituent of various marine organisms.
The possibility of discharging the calcium carbonate suspension overboard is currently under evaluation; this could potentially be easily dissolved by the larger volume of seawater.

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 CapLab will be opened in the coming months (in late spring) in Genoa, in the touristic port area.
