Carbon Ridge achieves shipping industry first with deployment of centrifugal carbon capture system aboard Scorpio Tankers vessel, securing additional funding to accelerate commercialization.
Houston, USA – In a landmark moment for maritime decarbonization, Carbon Ridge, a U.S.-based leader in onboard carbon capture and storage (OCCS) technology, has announced the successful deployment of the shipping industry’s first centrifugal carbon capture system aboard a commercial vessel. This milestone pilot, conducted in partnership with Scorpio Tankers Inc., signifies the first-ever integration of a centrifuge-based OCCS system into a working marine environment — a technological leap expected to reshape carbon management at sea.
The breakthrough installation took place in July at Besiktas Shipyard in Turkey on the STI SPIGA, an LR2 product tanker owned by Scorpio Tankers, a major global operator specializing in the transport of refined petroleum products. The initiative is designed to validate the performance, operational integration, and emissions-reduction capability of centrifugal OCCS in real-world shipping conditions.

Centrifugal OCCS: Designed for Shipping, Not Adapted from Shore
While conventional carbon capture systems deployed at sea often originate from land-based technology adapted for marine use, Carbon Ridge has engineered its system specifically for vessel integration from the outset. This purpose-built approach offers significant advantages in size, efficiency, and adaptability, making it uniquely suited for retrofit and newbuild applications.
Key features include:
- Modular, compact architecture — up to 75% smaller than conventional capture columns
- Flexible orientation — system can be installed vertically or horizontally, accommodating space constraints
- High capture efficiency — enables over 90% CO₂ capture from exhaust streams
- Multi-pollutant removal — eliminates over 99% of particulate matter, NOₓ, and SOₓ
- Fuel-agnostic design — compatible with conventional and alternative fuels
Captured CO₂ is compressed, liquefied, and safely stored onboard for the duration of the voyage, supporting future offloading and sequestration via Carbon Ridge’s logistics partnerships.
“Unlike other CCS solutions, which were designed for land-based use and retrofitted to fit vessels, our centrifugal system is engineered from the ground up for maritime,” said Chase Dwyer, CEO and Founder of Carbon Ridge. “It’s modular, efficient, and scalable — providing shipowners with a practical, near-term path to compliance and decarbonization without a total propulsion overhaul.”
Scorpio Tankers: Pioneering Carbon Capture at Sea
The deployment represents a strategic collaboration with Scorpio Tankers Inc., which operates one of the world’s largest fleets of product tankers. The company has committed to exploring innovative pathways to meet its environmental and regulatory goals, including through practical emission-reduction technologies.
“We’re proud to be part of this pilot with Carbon Ridge,” said Cameron Mackey, Chief Operating Officer of Scorpio Tankers. “Their approach to carbon capture is tailored to our industry’s operational realities. We believe this pilot will generate meaningful data that will help shape the next phase of maritime decarbonization.”
The STI SPIGA deployment will serve as a testbed for validating key operational metrics including capture efficiency, integration impacts, maintenance requirements, and compliance alignment with IMO and regional policies — including the EU Emissions Trading System (ETS) and FuelEU Maritime.
End-to-End Carbon Management: Beyond Capture
Carbon Ridge’s platform goes beyond onboard systems, offering a full value-chain solution for maritime CO₂:
- Transportation and offloading of captured CO₂
- Permanent sequestration partnerships
- Carbon credit monetization support
- Regulatory compliance guidance
This end-to-end model provides shipowners and charterers with a turnkey decarbonization package — reducing both emissions and administrative complexity.
“Decarbonization isn’t just about capture — it’s about storage, compliance, and economics,” Dwyer added. “We’re building an ecosystem that gives vessel owners a clear, cost-effective path forward.”
Funding Milestone: $20M+ Raised to Accelerate Scale
In parallel with the pilot launch, Carbon Ridge also confirmed the successful closing of a new funding round led by Katapult Ocean and Alfa8, with participation from Crosscut Ventures and Berge Bulk. This latest investment brings the company’s total funding to over $20 million USD, enabling further pilots, R&D, and commercial-scale deployments.
“This capital allows us to accelerate our commercial roadmap and expand pilot programs across vessel types and geographies,” said Dwyer. “It’s a strong signal from the market that our approach resonates with the needs of shipowners navigating an increasingly complex regulatory environment.”
Scalable, Future-Proof Solution for a Global Fleet
Carbon Ridge’s OCCS technology is engineered for global applicability across fleet types, sizes, and operational models. Its fuel-agnostic nature, compact footprint, and retrofit-friendly design offer a future-proof pathway that minimizes operational disruption while maximizing environmental benefit.
With IMO, EU, and regional regulators setting aggressive climate targets — including net-zero emissions for shipping by 2050 — centrifugal OCCS offers a realistic and deployable decarbonization strategy that aligns with both current regulations and long-term climate goals.
