The International Maritime Organization has set clear objectives towards drastically reducing greenhouse gas emissions the coming decades in the maritime sector. While different ways to reduce emissions are already proposed, these are not expected to generate high CO2 abatement rates (in the case of fuel saving measures) or to be available and cost competitive in the near future (in the case of alternative fuels). Alternatively, ship-based carbon capture (SBCC) technology could be implemented on the shorter term and has the potential to drastically reduce the CO2 emissions of the maritime sector. This study discusses the advancements made towards the SBCC technology on board of LNG-fuelled ships using the results of the DerisCO2 project. The study covers general design considerations for the SBCC technology (solvent selection, heat integration and effect of ship movement), next to specific design considerations for the Sleipnir ship of Heerema Marine Contractors (analysis of operational profile, conceptual design and high level integration of the SBCC system), which is used as a case study for SBCC in this paper. Simulation of the SBCC technology including a techno-economic analysis on the case studies are included. The SBCC technology is a technically and economically viable solution for the maritime sector to reduce emissions the coming decades, with the cost of CO2 capture for the Sleipnir calculated between 119-133 €/ton CO2. The most important proposed next step for fast development of the SBCC system is on board demonstration of the technology.@en

This chapter presents discussion of four selected case studies for sustainable carbon capture. The first case study is a high-level techno-economic integration study for CO2 capture in the waste to energy (WtE) sector, which may result in negative emissions, as a large part of the CO2 is biogenic. Integration of CO2 capture in this sector is essential when the need for district heating is low and/or heat is available at a relatively low price. The second case study describes a groundbreaking techno-economic integration study for CO2 capture on board ships, also called ship-based carbon capture (SBCC). The study considers the operational profile of the ship and uses the available heat integration options to minimize the costs of the process. The third case study entails the techno-economic evaluation of integrating carbon dioxide capture with a biogas facility for biogas upgrading to biomethane. The integrated cycle offers carbon-neutral energy with the potential for negative emissions by storing carbon dioxide underground. The final case study is related to the carbon capture applications in the cement and iron/steel sector.
