The potential trillion dollar cost of decarbonising international shipping using zero carbon fuels was highlighted to world leaders at the recent Davos summit. An alternative solution promising much lower costs has been developed by SME PMW Technology. A six month study of its marine application has just been awarded funding under the Department for Transport’s T-TRIG programme.
PMW Technology continues a successful long-standing collaboration with the University of Chester and teams with naval architects Houlder Limited and the Tees Valley Combined Authority to deliver this study.
Jonathan Strachan, director ship design & engineering at Houlder, said: “Houlder is delighted to be working with PMW Technology on this important study that we hope will offer a world-leading low carbon solution for shipping.”
The international shipping industry has reduced carbon emissions through improved designs, the use liquid natural gas as fuel and in enhanced operating practices. Despite this, current technology alone cannot reduce marine carbon emissions to the committed 50 per cent 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 per cent 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.
