Babcock International Secures Approval for Innovative Onboard Carbon Capture Solution

Babcock International Group's LGE division has achieved a significant milestone by securing Approval in Principle (AIP) from Lloyd's Register for its innovative onboard carbon capture solution, EcoCptr. This announcement, made during a prominent maritime industry event in Milan, highlights the accelerating focus on carbon reduction technologies within the shipping sector.

The EcoCptr system amalgamates two advanced technologies: Aqualung's membrane-based carbon dioxide capture and separation method, alongside Babcock's proprietary EcoCO2 system. This integrated approach is designed for both new vessels and retrofit projects, offering considerable environmental advantages and operational flexibility that align with the maritime industry's urgent transition towards lower emissions.

Onboard carbon capture systems (OCCs) are increasingly recognized as essential tools in the shipping industry's decarbonization efforts. While alternative fuels such as green methanol, ammonia, and hydrogen face challenges related to production and infrastructure, OCCs enable existing ships to continue utilizing conventional fuels while significantly reducing emissions. Capable of capturing up to 90% of carbon dioxide emissions from engine exhaust, these systems extend the operational lifespan of the current fleet and assist operators in adhering to increasingly stringent environmental regulations—an appealing prospect in an industry known for its slow fleet turnover.

Industry experts, including those from the Global Centre for Maritime Decarbonisation, highlight OCCs as a potential compliance advantage under the International Maritime Organization's net-zero framework. However, challenges persist, including increased operational costs due to fuel penalties, maintenance requirements, and a lack of port infrastructure to efficiently offload and store captured carbon.

Neale Campbell, Managing Director of Babcock's LGE division, emphasized that this AIP signifies not only technological advancement but also the company's dedication to innovation, particularly following its recent investment in Aqualung's funding round. With the growing interest in OCCs, the EcoCptr solution is well-positioned to facilitate immediate decarbonization efforts across global shipping.

Designed to simplify integration across a variety of vessel types, the EcoCptr system merges Babcock's EcoCO2 liquefaction technology with Aqualung's facilitated transport membrane, creating a modular, low-pressure carbon capture solution suitable for both new builds and retrofits. Campbell articulated that this recognition marks a crucial step in the EcoCptr journey, addressing the integration challenges posed by emerging technologies across diverse vessel types.

José Navarro, Global Gas Technology Director at Lloyd's Register, expressed satisfaction in awarding the AIP to Babcock's EcoCptr, acknowledging its potential to streamline onboard carbon capture through the fusion of membrane capture and CO2 liquefaction technologies. This development underscores the critical role of innovation in equipping shipowners with practical strategies to mitigate greenhouse gas emissions and comply with the International Maritime Organization's net-zero requirements.
