Cleaner maritime technologies

GE Power Conversion is marking the success of two innovation projects aimed at reducing maritime greenhouse gas emissions.

GE is helping to make progress towards net zero operations for ship and port operators through cleaner power systems and digital energy management.   At sea and on land, its electric microgrid systems can host integration of new energy sources and smarter digital and control technologies as they develop.

GE’s projects, part of the UK’s Clean Maritime Demonstration Competition, benefitted from partners’ vessel and port applications to accelerate solutions based on ‘real-world’ scenarios.

Power and energy specialists GE have been working on integration of multi-megawatt (MW) solid oxide fuel cell (SOFC) systems into a large ship architecture with partners Ceres, Lloyd’s Register and MSC Cruise Management (UK) Ltd.

The team’s efforts resulted in a major milestone – a collaborative design for up to 10MW on-board solid oxide fuel cell power installations.  At this scale, systems are able to provide electric power for large ships, and replace conventional diesel generating sets.  The system has the potential to reduce CO2 emissions by 47%, and significantly improve air quality and noise pollution when ships are in port. SOFC have the benefit of being able to operate on different types of new, cleaner fuels, a benefit as ship operators look to accommodate the transition to future fuels.

GE has also been working on reducing emissions at ports by helping to manage power and energy more efficiently.  With project partners PD Ports  Ltd, Connected Places Catapult and Teesside University, GE’s cloud-based, integrated digital concept aims to improve situational awareness on energy supply and demand.  Benefitting from PD Ports’ data has enabled the team to create operational scenarios to carry out testing using an emulated digital twin platform.   Digital energy management is part of GE Power Conversion’s range of Port Electrification solutions.
