Low cost CO2 capture for shipping study receives DfT funding

Apr 01 2020

A six month study of PMW Technology's marine cryogenic CO2 capture solution has been awarded funding under the UK Department for Transport’s (DfT) T-TRIG programme.

PMW Technology will continue a successful long-standing collaboration with the University of Chester and teams up with naval architects Houlder Limited and the Tees Valley Combined Authority to deliver the study.

The international shipping industry has reduced carbon emissions through improved designs, the use of liquid natural gas as fuel and in enhanced operating practices. Despite this, current technology alone cannot reduce marine carbon emissions to the committed 50% of 2008 levels by 2050. Zero carbon liquid ammonia has been proposed as a fuel. However this would require a trillion dollar investment in new fuel production facilities and vessel designs, with extra hazards for crews and the environment. 

PMW Technology’s process removes 95% of the carbon dioxide from engine exhaust gases, retaining existing fuels and engine technology. The liquefied carbon dioxide would be delivered to ports for transfer to geological storage. This alternative approach could cut costs substantially while accelerating the transition to low carbon shipping. The T-TRIG study will address the feasibility and economics of the concept for shipping; a positive outcome would be game-changing.

PMW Technology is a specialist process development company which has developed and patented the Advanced Cryogenic Carbon Capture (A3C) process. Based at Thornton Science Park in the UK, the company has worked closely with the University of Chester on a series of projects to validate and characterise the process and its components.

The A3C process uses a moving bed of fine metallic beads to cool gas mixtures so that the carbon dioxide deposits as a frost and can be separated. Intensive heat transfer in the bed results in a compact and energy efficient process.
