DNV Decarbonisation Insights: Singapore’s future opportunities in the CCUS and shipping value chain

As demand for flexible transportation of liquified CO2 increases, it becomes very apparent that those who are willing to partner with other stakeholders on CCUS projects will be rewarded in the years ahead.

How can the maritime industry respond to the global climate challenge to limit temperature rise to 1.5 °C?

Carbon Capture, Utilisation and Storage (CCUS) is gaining traction around the world as a technological solution which can conceivably reduce the impact of carbon dioxide (CO2) emissions. 

Some governments and energy producers are banking on it as a means to achieve Net Zero Emissions (NZE) in line with both the 2015 Paris Agreement and the most recent COP26 Conference in Glasgow. 

The International Energy Agency (IEA) sees CCUS as an important emissions reduction technology that can be applied across the energy system. Next to its permanent storage deep underground in geological formations, the captured carbon can also be used as a valuable resource to create synthetic fuels, chemicals, and industrial products.

Although the technologies and the industry are very much still emerging, a possible challenge is connecting capture sources to facilities for use or storage sites, especially where pipelines are not an option. As a result, CO2 transport ship technology will be needed if large quantities are to be safely transported economically.

Regional Manager for DNV Maritime Cristina Saenz de Santa Maria, who covers South East Asia, Pacific and India from her Singapore base, points to two fundamental reasons why CCUS may be a prerequisite to keep global emissions well below 2°C and ideally closer to 1.5°C:

  • Without using CCUS, it may be impossible to get emissions to net zero fast enough.
  • There are currently no competitive alternatives to CCUS for certain hard-to-mitigate sectors.

Commercial viability is key

But at this stage CCUS is not seen as being commercially viable and is not currently operating at sufficient scale anywhere in the world to make a big difference, though IEA does acknowledge that “strengthened climate goals and new investment incentives are delivering unprecedented momentum for CCUS”.

Even with more than 100 new facilities announced in 2021, “the planned pipeline of projects would fall well short of delivering the 1.7 billion tonnes of CO2 capture capacity deployed by 2030 in the Net Zero by 2050 scenario”, IEA writes.1

DNV reinforces this by asserting that the cost of emitting CO2 must be higher than the cost of abatement by CCUS.2

Maritime transport, however, can play an essential role in building up an efficient CCUS value chain, which is expected to lead to an increasing demand for specialised liquefied CO2 (LCO2) carriers.

Research undertaken by DNV and its partners, as well as by others in the shipping and energy industries around the world, suggest that there are distinct possibilities that CCUS could well become economically viable as a means to cut emissions, by safely transporting CO2 where it can be best utilised, sequestered or stored. 

Singapore’s role in building a CCUS supply chain

This leads us to the question whether Singapore could play a leading role in the CCUS supply chain – and the answer is certainly “yes”. 

Following a feasibility study on “Carbon Capture, Storage, and Utilisation: Decarbonisation Pathways for Singapore’s Energy and Chemicals Sectors”, the government said it sees the technology as an integral part in the city state’s transition to a low-carbon future.3

Only a few months after this announcement promoting CCUS and other low-carbon technological solutions, a memorandum of understanding (MoU) between Singapore LNG (SLNG) and Linde Gas hit the news. In December 2021, both partners announced they will explore options of a CO2 liquefaction and storage facility, located adjacent to the SLNG Terminal on Jurong Island.4

The CO2 concept project involves using cold energy from SLNG’s own operations to liquefy CO2, which they will store in tanks onsite before they transport it later for end-use. If feasible, this could be the first such facility in Singapore and the region. 

Tan Soo Koong, CEO of SLNG, said at the time that energy security is of utmost importance, and it is also “our vision to catalyse new possibilities in the energy transition and this includes supporting new solutions for a lower carbon future, in step with the government’s Singapore Green Plan 2030.”

Maritime transportation of CO2

Looking into the potential of CCUS for the maritime sector, Dr Sanjay C. Kuttan, Chief Technology Officer at the Global Centre for Maritime Decarbonisation (GCMD), sees significant opportunities: While Singapore most likely will not have sufficient carbon sequestration opportunities within its national boundaries, as a major port and petrochemical centre it could become an important hub to aggregate CO2 captured from vessels and domestic operations to be sequestered elsewhere in the region, using CO2 carriers.

“These carriers can either be dedicated for CO2, or LNG carriers modified in order to take advantage of available ullage – or surplus space onboard – on their return journey,” Dr Kuttan explains.

It’s also possible that Singapore could function as a final port to consolidate captured CO2 within a regional network, where such aggregation can be achieved from a “milk-run” like operation between other ports to Singapore before heading out to the sequestration fields within regional waters. This would require the optimisation of vessel sizes for differing amounts of captured CO2 to be transported.

Dr Kuttan expects that sequestration will be operationally and commercially viable in the future with the increasing volumes of captured CO2, as it will benefit from the economies of scale. 

“In the interim, as we explore and ramp up deployment of on-board carbon capture (OBCC) solutions, Singapore can create impact by having in place utilisation pathways for the captured CO2 to close the CO2 emission loop and make the effort to decarbonise the vessel more effective,” he says.

The initiatives by government agencies in Singapore, over the decade and more recently, with the example of the Low-Carbon Energy Research (LCER) Funding Initiative, could prove advantageous as they also target the production of aggregates and synthetic chemicals. 

Coordination across all sectors is needed

However, Dr Kuttan does think that there is a need for better coordination between governments and the private sector to scale up these solutions at a system level across sectors.

There’s no doubt that moving CO2 across national boundaries poses legal and liability challenges that need to be addressed collectively by nations where their borders are in play.

Accounting and assignment of carbon abatement to the right parties is also required, and the complexity of business agreements between the parties in capturing, storing, transporting, and sequestering is not trivial. Also, standards and procedures need to be clearly articulated for safe operations.

Looking ahead, GCMD sees a good opportunity for Singapore to orchestrate a robust system of integrated solutions around CCUS and shipping. This would include onboard CCUS technology, as well as the delivery and off-loading of CO2 to utilisation or sequestration assets (land-based or floating). 

Dr Kuttan also believes that Singapore based shipyards can “up the ante” by playing a more active role in retrofitting or building vessels with on-board CCUS systems.

Significant abatement potential for the maritime sector

In summary, GCMD considers carbon capture and sequestration as a solution that could create significant abatement potential for the maritime sector. It could also extend the runway of current carbon fuels to reduce the carbon load on the environment as green ship fuels ramp up to scale. In the case of green fuels, for example bio-derived fuels, CCUS could provide even negative emission opportunities. 

“We need a coordinated and collaborative approach to ensure that CCUS delivers a sustainable decarbonisation platform, as it is complex and, furthermore, requires those who will benefit the most commercially from the execution to invest equitably in realising the full value of CCUS,” Dr Kuttan concludes.

Cristina Saenz de Santa Maria DNV MT

DNV, a founding member of the GCMD, shares the same views. Ms Saenz de Santa Maria reinforces incentives are needed to get the investment required to build the infrastructure – on land and on water – and all parties must work together: “Public private partnerships are vital, along with having the necessary regulations in place, as well as committing to maintain the highest possible safety standards. There cannot be a trade-off between decarbonisation and safety.”

She also notes that DNV has played a pioneering role in the transportation of liquified CO2, as the company has offered class services to CO2 carriers since 1988.

Developing low-pressure solutions for the transportation of CO2

While shipping represents an alternative to pipelines, there are certainly some technical challenges that need to be addressed. 

Martin Cartwright, DNV’s Business Director Gas, Carriers & FSRUs, explains that to efficiently transport CO2 at industrial scale, the industry needs to look into different options, including high-, medium-, and low-pressure solutions, which will help integrate seaborne transportation into the CCUS value chain.

“Through our work with various partners, we have developed expertise specific to vessel design, specialised tanks, piping and refrigeration systems for the transportation of liquified CO2,” he reports.  

Ms Saenz de Santa Maria points to a recent example where DNV is involved with four other significant players – Equinor, Shell, Total Energies, and Gassco – in a new Joint Industry Project (JIP) to develop low-pressure solutions for the transportation of CO2 by ships.5

The CETO (CO2 Efficient Transport via Ocean) project will carry out the technology qualification of a low-pressure ship design and identify solutions to scale CO2 transportation volume, while reducing the associated risks, to support the development of opportunities in CCUS.

DNV’s VP Special Projects-Gas, Johan Petter Tutturen, makes it very clear that it was essential that CO2 ship designs need to be reliable and meet accepted safety standards: “That is why we are very pleased to be working together with this strong consortium of CCUS stakeholders to identify the technical risks and challenges to enable safe and economical operations going forward.”

Safety first, while balancing cost and operational complexity

Mr Tutturen also draws attention to DNV’s participation in several further Joint Industry Projects evaluating alternatives for transporting CO2 at both high and low pressures. “Factors being considered, among others, include choice of material for the containment system, effect of impurities in the cargo, transport volumes, safety considerations, and achieving the optimal balance between cost and operational complexity,” he states. 

Ms Saenz de Santa Maria highlights the Northern Lights project funded by the Norwegian Government, which involves DNV, along with other industry parties, in a full scale “Longship” demonstration for the capture, transportation, and storage of CO2.

Announced in December 2020, in the first phase it will capture CO2 from industrial sources in the Oslofjord region and ship it in liquid form to an onshore terminal on the Norwegian west coast. From there it will be carried by pipeline to an offshore storage complex in the North Sea.

In October 2021, the project announced the construction of two dedicated CO2 carriers, with a cargo size of 7,500 cubic metres (CBM).

DNV acknowledges that the Northern Lights project shows how a public private partnership can be leveraged to make a carbon, capture and storage concept a reality and inspire other groups to develop their own CO2 projects.

Shipyards launching CO2 carrier designs

Considering the future market potential, more and more shipyards are getting active, too.

In September 2021, DNV and the Liberian International Ship & Corporate Registry (LISCR) announced they awarded an Approval in Principle (AiP) to Hyundai Heavy Industries (HHI) and Korea Shipbuilding & Offshore Engineering CO (KSOE) for a new 40,000 CBM liquified CO2 carrier design. 

“We are delighted to work with HHI, KSOE, and LISCR, and to be able to approve this innovative LCO2 carrier design,” commented Vidar Dolonen, Regional Manager Korea & Japan at DNV Maritime. “Our role is to support bringing these ship designs to life for a safer and more sustainable future.”

The planned 40,000 CBM class LCO2 carrier is 239m long, 30m wide, and has a depth of 21m. The vessel will be equipped with seven IMO type-C cargo tanks. It is designed to carry LCO2 cargo only, but multi-cargoes, such as LPG or ammonia, can also be considered.

“Obtaining the AiP for this innovative large scale LCO2 carrier is a meaningful technological milestone. We believe our self-developed LCO2 carrier will contribute to global decarbonisation efforts by providing tailor-made designs according to each ship owner’s specific requirements,” said Mr. Won-Ho Joo, Senior Executive Vice President and Chief Technical Officer at HHI.

What all these CCUS and shipping projects confirm for Ms Saenz de Santa Maria and others at DNV Maritime is that while the technology won’t be a showstopper it will require collaborative action involving regulators, politicians, ship managers, ports, yards, suppliers, and classification societies to make a real difference.

As demand for flexible transportation of liquified CO2 increases, it becomes very apparent that those who are willing to partner with other stakeholders on CCUS projects will be rewarded in the years ahead.

It’s worth drawing attention to the essence of what DNV concludes in its “Pathway to Net Zero Emissions” report released in October 2021: Carbon capture and removal technologies are a must if the world has any chance of meeting the 1.5 °C limit for temperature rise.6

Singapore-based Eastern Pacific Shipping (EPS) on Thursday (22 February) said it signed a contract for its first ever wind-assisted propulsion system, partnering with bound4blue to install three 22-metre eSAILs® onboard the Pacific Sentinel

The turnkey ‘suction sail’ technology, which drags air across an aerodynamic surface to generate exceptional propulsive efficiency, will be fitted later this year, helping the 183-metre, 50,000 DWT oil and chemical tanker reduce overall energy consumption by approximately 10%, depending on vessel routing.

Suitable for both newbuilds and retrofit projects, the system delivers energy efficiency and cost savings for a broad range of vessels, regardless of their size and age.

Singapore: EPS orders its first wind-assisted propulsion system for tanker

José Miguel Bermudez, CEO and co-founder at bound4blue, said: “Signing an agreement with an industry player of the scale and reputation of EPS not only highlights the growing recognition of wind-assisted propulsion as a vital solution for maximising both environmental and commercial benefits, but also underscores the confidence industry leaders have in our proven technology.”

“It’s exciting to secure our first contract in Singapore, particularly with EPS, a company known for both its business success and its environmental commitment.”

“We see the company as a role model for shipping in that respect. As such this is a milestone development, one that we hope will pave the way for future installations across EPS’ fleet, further solidifying our presence in the region.”

Cyril Ducau, Chief Executive Officer at EPS, said: “EPS is committed to exploring and implementing innovative solutions that improve energy efficiency and reduce emissions across our fleet.” 

“Over the past six years, our investments in projects including dual fuel vessels, carbon capture, biofuels, voyage optimisation technology and more have allowed us to reduce our emissions intensity by 30% and achieve an Annual Efficiency Ratio (AER) of 3.6 CO2g/dwt-mile in 2023, outperforming our emission intensity targets ahead of schedule. The addition of the bound4blue groundbreaking wind assisted propulsion will enhance our efforts on this path to decarbonise.”

“With this project, we are confident that the emission reductions gained through eSAILs® on Pacific Sentinel will help us better evaluate the GHG reduction potential of wind assisted propulsion on our fleet in the long run.”

Pacific Sentinel will achieve a ‘wind assisted’ notation from class society ABS once the eSAILs® are installed.

LNG Bunkering

Galveston LNG Bunker Port joins SEA-LNG coalition

SEA-LNG said move will further enhance its LNG supply infrastructure expertise and global reach, while giving GLBP access to the latest LNG pathway research and networking opportunities.





Galveston LNG Bunker Port joins SEA-LNG coalition

Galveston LNG Bunker Port (GLBP), a joint-venture between Seapath Group, one of the maritime subsidiaries of the Libra Group, and Pilot LNG, LLC (Pilot), a Houston-based clean energy solutions company, has joined SEA-LNG, according to the latter on Wednesday (21 February). 

SEA-LNG said the move will further enhance its LNG supply infrastructure expertise and global reach, while giving GLBP access to the latest LNG pathway research and networking opportunities.

GLBP was announced in September 2023 and will develop, construct and operate the US Gulf Coast’s first dedicated facility supporting the fuelling of LNG-powered vessels, expected to be operational late-2026.

The shore-based LNG liquefaction facility will be located on Shoal Point in Texas City, part of the greater Houston-Galveston port complex, one of the busiest ports in the USA. This is a strategic location for cruise ship LNG bunkering in US waters, as well as for international ship-to-ship bunkering and cool-down services. GLBP will offer cost-effective turn-key LNG supply solutions to meet growing demand for the cleaner fuel in the USA and Gulf of Mexico.

Jonathan Cook, Pilot CEO, said: “With an initial investment of approximately $180 million, our LNG bunkering facility will supply a vital global and U.S. trade corridor with cleaner marine fuel. We recognise that SEA-LNG is a leading partner and a key piece of the LNG bunkering sector, and will give us access to insights and expertise across the entire LNG supply chain.

“LNG supports environmental goals and human health by offering ship operators immediate reductions in CO2 emissions and virtually eliminating harmful local emissions of sulphur oxides (SOx), nitrogen oxides (NOx) and particulate matter.”

President of Seapath, Joshua Lubarsky, said: “We are very pleased to be supporting the decarbonization of the maritime industry through strategic, and much needed, investments into the supply of alternative fuels.  We are also happy to be a part of SEA-LNG which has done a wonderful job in advocating for advancements in technology in this vital sector.”

Chairman of SEA-LNG Peter Keller, said: “We’re proud to welcome another leading LNG supplier to the coalition and are looking forward to a mutually beneficial relationship. With every investment in supply infrastructure in the US and worldwide, the LNG pathway’s head start increases. Global availability, alongside bio-LNG and e-LNG development, makes LNG the practical and realistic route to maritime decarbonisation.

“All alternative fuels exist on a pathway from grey, fossil-based fuels to green, bio or renewable fuels. Green fuels represent a scarce resource and many have scalability issues, so we must start our net-zero journey today with grey fuels. LNG is the only grey fuel that reduces greenhouse gas emissions, well-to-wake, so you need less green fuel than alternatives to improve emissions performance.”
