Technical, economic, and environmental assessment of CO₂ ship transport in carbon capture and storage

Journal of Environmental Management

This article explores the potential of CO₂ shipping to support carbon capture, utilisation, and storage (CCUS) efforts in the UK, introducing a techno-economic and environmental framework evaluating the maritime transportation of 5.9 million tonnes of CO₂ annually from the Solent region. This volume is equivalent to removing approximately 1.3 million cars from the roads. The assessment covers carbon capture, liquefaction, maritime transport, energy utilisation, and storage processes. The research highlights the importance of cost-effectiveness in making CO₂ transport by sea viable. It identifies strategies such as using larger, low-pressure vessels, offering port and energy incentives, and increasing carbon pricing to reduce costs and environmental impacts. By improving maritime CO₂ transport, this study supports scaling up CCUS and addressing climate change challenges.
