Conoship carbon capture

Vessel design and engineering firm Conoship on Monday (14 June) issued a statement declaring its stance against World Bank’s view over role of LNG bunker fuel for maritime decarbonisation:

BRIGHT FUTURE FOR LNG FUELED VESSELS WITH CARBON CAPTURE SYSTEMS

In contrary to the World Bank point of view, there is a bright future for LNG in the decarbonization of the shipping industry. The World Bank report seemed to have missed an important recent technical development: Marine Carbon Capture Systems. Recently, great progress has been achieved regarding the capturing of CO2 from the exhaust of LNG-fueled ships.

Among others, R&D in the Netherlands – by Conoship, TNO Delft and other partners – leads to feasible and practical ship-based solutions, utilizing ‘the cold’ of the LNG (-160 dgr. C) to liquefy the CO2 and store it in regular liquid-CO2-tankcontainers on board. The captured CO2 can be unloaded while bunkering LNG, to be stored for example offshore in empty gas fields, for which infrastructure is under development in Norway (Northern Lights), Rotterdam (Porthos), Amsterdam (Athos) and by parties like CarbonCollectors.

As the captured and liquefied CO2 can be ‘food-grade’, wider utilization is foreseen in the future as an important and valuable feedstock for the production of synthetic fuels, like synthetic-kerosine, -diesel, -methanol or -methane. Next to ‘green hydrogen’, the production of synthetic fuels requires vast amounts of CO2, for which ‘direct air capture’ is a very inefficient source.

The same ships that actually are fueled by LNG (= abt. 85% Methane CH4), can be fueled in the future by Liquified Synthetic-Methane (LSM, 100% CH4), using the same existing LNG-infrastructure. A closed carbon-loop can be realized by capturing the CO2 after the combustion of LSM in the ship, liquefying it and providing it as feedstock to the producer of the Liquified Synthetic Methane.

Conoship R&D and design studies show that by future application of onboard CO2-capturing, liquefaction and storage, LNG-driven ships can both be:

  • a good direct economic and ecological alternative to diesel-driven ships, realizing large reductions of SOx, NOx en PM/Sooth and smaller reductions of CO2;
  • a good future-proof economic and ecological solution, increasing the reduction of CO2-emissions (possibly stepwise) to the desired economical & ecological level by application of a CO2-capturing installation.

By integrating the CO2-capturing installation in the initial ship design at Conoship, we reduce the future impact of the modification. However, CCS installations are also suitable for retrofits on board of LNG powered vessels.

The studies we have done tend to show that LNG combined with CO2 capture is the first solution to become economically feasible.

Further R&D on handling the challenge of methane slip is making good progress, both in combustion technology in engines and in after-treatment technology and there is no reason why application of the solutions should be limited to a fraction of the fleet. Furthermore, despite all developments, the quantity of “green hydrogen”, either to be used directly as fuel, or as feedstock for e-fuels, will remain limited. It would make sense to use this scarce quantity for applications for which there are no alternatives, such as in long range aviation.

Introduction, through IMO, of a CO2-levy per ton emitted CO2 will facilitate the economical application of CO2-capturing installations on LNG-driven vessels in the coming years. All in all LNG, when combined with CCS, should therefore still be considered as a more than valuable transition fuel up to 2050, reducing the carbon footprint of shipping and its customers with more than 75% compared to today’s diesel powered operations.

US Representatives Nanette Barragán and Troy A. Carter, Sr., along with Senator Chris Van Hollen, on Friday (26 June) reintroduced the Next Generation Shipping Act. 

The legislation would create a USD 1 billion per year programme through the Department of Transportation’s Maritime Administration (MARAD) to develop the next generation of clean shipping technology and infrastructure. 

The lawmakers said the bill would help to address harmful pollution that comes from the shipping industry, a major but often unrecognised source of greenhouse gas emissions and port pollution. 

Through the development and usage of new technologies— such as zero-emission ships, cleaner marine fuels, and better port equipment— the programme seeks to protect the health of port and coastal communities, and help the US reduce its climate pollution.

They added that the bill would also help the United States keep up with other countries in Europe and Asia that are already investing heavily in clean shipping technology. The bill would ensure that the U.S. leads in the future of shipping, rather than rely on technology from other countries.

“Shipping plays a vital role in our economy, and at the Ports of Los Angeles and Long Beach, but it should not come at the expense of the health of our families,” said Rep. Barragán. 

“The Next Generation Shipping Act is about investing in cleaner technologies, supporting American jobs, making sure the United States leads in the future of maritime innovation, all while making sure we do so in a way that preserves public health. By acting now, we can protect our communities, strengthen our economy, and build a more sustainable shipping industry for generations to come.”

“The Next Generation Shipping Act is forward-thinking legislation that will help revitalise the U.S. maritime industry and boost our economic competitiveness. As the federal government looks to expand commercial shipbuilding capacity, the U.S. must invest in cleaner ships and technologies to compete globally,” said Antonio Santos, Federal Climate Policy Director, Pacific Environment. 

“The bill provides much-needed funding to position the US to be a leader in the development of next-generation vessel technologies and sustainable maritime fuels, while creating good-paying jobs and supporting workforce training. We thank Representative Barragán, Representative Carter, and Senator Van Hollen for introducing this important legislation and call on Congress to pass this bill to spur the market for building the advanced ships of the future.”

DNV: How low‑GHG methane can future‑proof LNG-capable vessels

Classification society DNV on Monday (22 June) published a Maritime Impact article, summarising the key findings of its Methane in shipping paper, helping shipowners of LNG-capable vessels to meet stricter GHG reduction requirements, and optimise LNG‑based fuel strategies for future compliance: 

Excluding LNG carriers, more than 800 ships can run on LNG using mature, proven technology and established infrastructure, with over 600 more on order.

Under the FuelEU Maritime regulation, LNG‑capable ships can remain compliant on fossil LNG until around 2035, depending on engine configuration. Ships fitted with two‑stroke high‑pressure dual‑fuel engines can remain compliant longer than those using four‑stroke low‑pressure dual‑fuel engines, which are more common in cruise ships and RoPax vessels.

Extending LNG compliance with low-GHG options

DNV’s Methane in Shipping white paper indicates that a potential compliance pathway is the use of LNG-compatible low-GHG fuels. LNG ships are compatible with alternatives such as liquefied bio-methane and e-methane. With tightening GHG intensity requirements, these ships are thus well positioned to transition towards lower GHG emission fuels without major retrofits for these alternatives.

“Bio-methane and e-methane can achieve very low, or even negative, life cycle emissions depending on how they are produced. LNG-fuelled vessels can progressively decarbonize by blending in or switching to these fuels,” explains Øyvind Sekkesæter, Senior Consultant at DNV and lead author of the paper.

Demand for low-GHG methane will grow with tightening regulations

According to demand projections outlined in the paper, compliance-driven low-GHG methane demand under FuelEU Maritime alone could reach 2–4 million tonnes by 2040, rising to as much as 40–95 million tonnes under the proposed IMO Net Zero Framework’s base target.

On the supply side, current production of low-GHG methane is limited, but still higher than many other low-GHG fuel alternatives. Global bio-methane production reached around 7 million tonnes in 2024 and is projected to increase to about 15 million tonnes by 2030. E-methane remains nascent, with only 0.01 million tonnes of operational capacity today, but announced projects could lift this to 0.9 million tonnes by 2030.

t3 ind 636 bio methane production in key markets

While there is significant potential to expand the global supply of low-GHG methane beyond today’s production levels, shipping will compete with other sectors for this supply. Most available supply is already absorbed by power generation and road transport, meaning access for shipping will largely depend on its willingness to pay relative to other users.

Dan-Bunkering supports Sallaum Lines with LNG bunkering operation in China

Global bunker supplier Dan-Bunkering on Friday (19 June) said it has recently concluded an LNG delivery in China for Sallaum Lines’ newbuild Pure Car and Truck Carrier (PCTC), Ocean Express

The delivery involved approximately 1,400 metric tonnes (mt) of LNG bunker fuel. 

This delivery is the outcome of a development process that began around April 2025, during which Dan-Bunkering worked with Sallaum Lines to evaluate several LNG supply opportunities in China linked to the company’s newbuild programme. 

Ocean Express is one of six newbuilds in the series and represents the fourth supply opportunity Dan-Bunkering has supported so far.

For this delivery, Dan-Bunkering said it secured a ship-to-ship supply solution aligned with the vessel’s operational requirements. The solution was made possible through close cooperation with supply partner SIPG Energy.

“This is a great example of what it takes to support clients in the transition to alternative fuels,” said James Shiller, Global Lead of New Fuels at Dan-Bunkering, and continues:

“LNG bunkering is not always straightforward, particularly during a first full bunker operation. Success depends on local knowledge and persistent cooperation across teams. Sallaum Lines trusted us and SIPG Energy to keep working the options, and we are proud that all involved teams turned a challenging situation into a successful delivery. We value the relationship and look forward to supporting their remaining newbuild deliveries.”

The company added that the delivery was made possible through close coordination across Dan-Bunkering and the wider Group, including Dan-Bunkering’s Netherlands office, Bunker Holding’s specialists and sourcing team.
