Project Summary
This project addresses de-carbonisation of marine transport. Its objective is to develop and validate a prototype carbon capture process for marine diesel engines. The team will add essential pre-treatment components and evaluate the performance of the A3C process in carbon capture trials using real engine exhaust gases.
Project Achievements
- Defined the trial application including exhaust gas flows, temperatures and composition. Sized conventional and unconventional elements of the process to handle the thermal and chemical duties.
- Identified and procured components to handle the small gas flows (<10 l/s).
- Designed and manufactured custom components for moving bed heat exchanger process.
- Experienced difficulties and delays in the manufacture of critical gas injectors which introduce the gases into the slow-moving bed of the cooler-drier and other custom components.
- Despite this, the process proved highly effective in cooling and cleaning the gases, reducing inlet temperatures of up to 300°C to -100°C.
Next Steps
- The clean-up unit will form part of a complete end-to-end demonstration of the A3C process scheduled for later this autumn. PMW Technology will be seeking investment partners to support a prototype demonstrator for A3C carbon capture using this cleanup process, first onshore and then onboard for sea trials. The aim is for the prototype to capture carbon dioxide from an auxiliary engine of up to 1000 kW rating.
- The ambition is for the A3C process to support the use of methanol as a hydrogen carrier, capturing carbon dioxide to be returned to the green methanol plant.
