The Green Marine project will develop retrofitting protocols, a software tool catalogue and demonstrate innovative carbon capture, energy-saving, and fuel consumption reduction technologies. The solutions will be tested on land-based engines before being demonstrated on a waterborne vessel. The consortium includes 10 partners from 7 countries, consisting of 6 SMEs, 3 research institutes, and a major ferry operator.
Objectives of the project:
- Develop and validate retrofitting protocol tools suitable for adapting engines, flue gas carbon capture and utilisation, and integrated energy-saving solutions for ships.
- Tailor a (nano)particle and virus removal solution and demonstrate the significant HVAC energy savings that can be achieved by reusing virus-free air in enclosed areas.
- Tailor commercially available gas-gas separating membranes for CO2 and water capture.
- Develop and implement a carbon capture solution based on an alkaline solution with Ca and Mg from seawater.
- Develop and validate a software tool containing an up-to-date catalogue of suitable solutions for a wide variety of ship types and operation scenarios.
- Replicate project learnings and stimulate the use of the developed software tools to further enrich its data.
- Firmly position our retrofitting, software tools as a sustainable solution for Carbon Capture Utilisation and Storage (CCUS) market.
Membrane separation is a promising decarbonization technology suitable for application on ships, where footprint, weight and space limitations are important design constraints to be considered. Membrane installations for CO2 capture can overcome the constraints imposed by ship operation and design due to the intrinsic simplicity of installation, modularity, low weight, and footprint. Cleaning diesel exhaust from ships imposes additional challenges represented by a low and variable 3- 8 % CO2 content depending on the ship, engine type and engine loading leading to a low driving force for separation.
SINTEF role Is to develop a CO2 capture membrane pilot has been designed for testing at TRL 6 onboard a ship. Our focus is on upscaling both flat sheet and hollow fiber geometry membranes from laboratory scale to small pilot scale modules membranes tested with real diesel exhaust. The Green Marine project will demonstrate a capture rate of > 35% CO2 from diesel exhaust ships using a single stage membrane concept. Recovery rates in the range up to 90% will be explored theoretically using simulation models of multistage systems.
