First Centrifugal on Board Carbon Capture System Launches 

Carbon Ridge claims to have launched the first on board centrifugal carbon capture system on a commercial vessel.

The installation of the fuel-agnostic system took place on board the STI Spiga, a vessel operated by Scorpio Tankers, in conjunction with risk management and assurance provider DNV, Spitzer Industries, Endress + Hauser Group, and Besiktas Shipyard.

Instead of relying solely on gravity for separation, as in traditional columns, the system uses a rotating component to create a strong centrifugal force, leading to more efficient CO2 absorption. It is also a more compact option, occupying 75% less space than traditional units.

DNV recently released a new service specification for the verification and certification of carbon capture, utilisation and storage (CCUS) facilities.

DNV-SE-0696 provides a structured methodology to de-risk CCUS projects across design, construction, and operation – unblocking a key industry need as carbon capture scaling rates remain slow globally.

Shipowners should consider onboard carbon capture and storage at the newbuilding stage to reduce potential retrofit costs, according to DNV.

Key factors that affect the technical feasibility of onboard carbon capture are size, operational profile and trading pattern, machinery capacity for power and heat production, and space available.

It acknowledges scaling up of the maritime carbon capture network "will take time" and is expected to reach a broader uptake after 2030.

By April 2024, 35 carbon storage projects were in operation worldwide with a total storage capacity of 37 million tonnes per annum, most of them related to natural gas processing and enhanced oil recovery.

"The application and uptake of onboard carbon capture technology depends on the relevant cost elements of the system, in addition to the regulatory and competitive landscape," it states.

"In general, as long as decarbonisation of shipping is enforced through regulations and market-based mechanisms, onboard carbon capture may be a commercially attractive solution if high capture rates, low fuel penalties, and low CO2 deposit costs can be achieved."
