Study finds OCCS could reduce up to 20% CO2 emissions on “Stena Impero”

Engineering project found that the technology could reduce the vessel’s carbon dioxide (CO2) emissions by as much as 20% per year, with a fuel consumption penalty of just under 10%.

Study finds OCCS could reduce up to 20% CO2 emissions on “Stena Impero”

A project assessing the technical feasibility of onboard carbon capture and storage (OCCS) in the shipping sector has concluded that the technology has the potential to help maritime transport significantly reduce its greenhouse gas emissions, according to a joint statement on Thursday (10 October).

The engineering project analysed the design and cost implications of retrofitting a carbon capture system on the medium-range tanker Stena Impero. It found that the technology could reduce the vessel’s carbon dioxide (CO2) emissions by as much as 20% per year, with a fuel consumption penalty of just under 10%.

The project was carried out by the Oil and Gas Climate Initiative (OGCI), the Global Centre for Maritime Decarbonisation (GCMD) and Stena Bulk together with a consortium of maritime organisations.

The project, Realising Maritime Carbon Capture to Demonstrate the Ability to Lower Emissions, (REMARCCABLE) was supported by a consortium comprising American Bureau of Shipping, Alfa Laval, Deltamarin, Lloyd’s Register, Seatrium, and TNO. It aimed to assess the viability of deploying carbon capture systems on vessels with minimal impact on operational constraints.

The cost of building and installing the full system on the Stena Impero is estimated at USD13.6 million, with an abatement cost of avoided CO2 for the first-of-a-kind prototype evaluated at USD 769/tonne CO2.

However, the consortium believes that further research and development will drive down costs, making OCCS increasingly viable for the shipping industry.

The study also looked at incorporating OCCS on newbuild vessels, with the findings that improvements to capture rate and fuel penalty may be achieved using more efficient engines, heat pumps, and alternative solvents.

Professor Lynn Loo, CEO of GCMD, said: “OCCS has gained traction in recent years as a feasible approach to meet the 2023 IMO revised GHG emissions reduction targets. However, its adoption faces numerous hurdles, including the need to balance the tension between maximising CO2 capture rates while maintaining commercially acceptable CapEx and OpEx. This study provides quantitative insights on managing the trade-offs between the actual cost of operating OCCS and its emissions reductions potential.

“For OCCS systems to be practical, the industry needs to manage captured CO2 effectively. To this end, GCMD has previously completed a study to define the operational envelope for offloading onboard captured CO2, contributing to the whole-of-system approach to emissions reduction via carbon capture.”

ZeroNorth and Veracity by DNV launch end-to-end emissions reporting, verification service

Maritime technology solutions provider ZeroNorth on Friday (16 May) said it has partnered with Veracity by DNV to launch a fully integrated emissions reporting and verification service for the maritime industry.

Teekay is the first customer that will be implementing the service across its fleet, following successful testing and development.

As regulatory requirements tighten, ZeroNorth said maritime operators face growing demands for emissions transparency and reporting integrity. At the same time, poor data quality remains an industry-wide challenge.

“The new offering combines ZeroNorth’s Vessel Reporting and Emissions Analytics platform with the Veracity platform and DNV’s Emissions Connect verification services to deliver an end-to-end compliance solution,” the company said in a statement.

“The offering simplifies compliance by integrating automated data reporting with expert validation, reducing administrative burdens and improving data reliability.”

A key differentiator is the multi-layered data quality feedback loop, which ensures emissions data undergoes rigorous validation at multiple stages. Verification warnings from Veracity by DNV are automatically flagged to ZeroNorth’s data quality team, which then works directly with vessel crews to resolve discrepancies before final submission to authorities.

This reduces compliance risks and enhances regulatory confidence while supporting continuous monitoring of EU MRV, IMO DCS, CII ratings, EU ETS and FuelEU Maritime compliance.

Teekay, a long-standing customer of ZeroNorth, participated in early testing of the solution and providing operational feedback. Since its successful implementation with Teekay, the service has been rolled out to two additional customers, and further deployments are underway.

Anders Schulze, Chief Operations Officer at ZeroNorth, said: “The maritime industry faces growing pressure to ensure emissions data is not just reported, but verified to the highest standards. Yet fragmented systems and manual processes continue to undermine data quality and increase compliance risk.

“By combining ZeroNorth’s data and analytics capabilities with Veracity by DNV’s verification expertise, we are directly addressing this challenge. Our goal is to build trust in emissions data and reduce complexity for shipowners and charterers. We’re especially pleased that Teekay, a long-time partner, played a central role in shaping and validating the service.”

Mikkel Skou, Managing Director at Veracity by DNV, said: “At Veracity by DNV, the value of our ecosystem is built on strong partnerships, exemplified by our collaboration with ZeroNorth.

“By integrating trusted data and solutions like ZeroNorth’s Vessel Reporting and Emissions Analytics platform, we create a robust network that supports collaboration and drives sustainable growth in the maritime industry.

“We look forward to continuing working towards our ambition to deliver trust and connectivity to the industry through this partnership with ZeroNorth.”

Mikkel Seidelin, Chief Commercial Officer at Teekay, said: “Partnering with ZeroNorth improves our ability to navigate complexities seamlessly, leveraging on data and technology to optimise our performance and reduce inefficiencies.

“When we are equipped with verified, end-to-end data, it empowers us as owners towards seamless decision-making, resulting in real sustainable and operational target-achievements.”

Shipergy expands global presence with two key hires in Hong Kong and New York

Tech-driven marine fuel trading company Shipergy on Tuesday (13 May) announced the appointment of two seasoned industry professionals to strengthen its global presence and enhance its service capabilities.

Kingsley Chan joins the company’s operations in Hong Kong, while Michael Bergendorff takes on a key role in New York, marking significant steps in Shipergy’s ongoing expansion strategy.

“We are delighted to welcome Kingsley and Michael to our growing team,” said Michael Stig Nielsen, CCO of Shipergy.

“Their extensive industry experience and regional knowledge will be invaluable as we continue to expand our global footprint and deliver exceptional value to our clients across key maritime hubs.”

Bergendorff has over 17 years of experience in the shipping, logistics, and bunkering industry to Shipergy. Most recently serving as Managing Director and Partner at The Bunker Firm, where he oversaw operations in the Americas and APAC regions, Bergendorff’s expertise in developing effective strategies that optimize operations and enhance customer satisfaction aligns perfectly with Shipergy’s client-focused approach.

Chan joins Shipergy with 20 years in sales, account management, and business development. Previously a Bunker Trader at Baseblue, Shipergy said Chan’s experience in the Hong Kong market and understanding of marine products and services will strengthen the company’s presence in the Asian region.

The company has its proprietary technology platform, The Wave, which uses real-time data, AI, and machine learning to provide visibility into fuel quality, availability, and decarbonisation potential.
