Technology group Wärtsilä on Wednesday (13 September) said it will supply an integrated hybrid propulsion system for two new hybrid RoRo vessels. 

The ships are being built at the China Merchants Jinling shipyard (Weihai) Co., Ltd for the Swedish shipping company Stena RoRo. The ships will be the world’s first methanol fuelled hybrid RoRo vessels and will operate in the Stena Line Irish Sea system. 

The combination of new sustainable fuels and electrification is in line with the company’s sustainable operations target. Part of the order was booked by Wärtsilä in Q2 2023, while the remaining order was booked in Q3 2023.

Each vessel will be equipped with two Wärtsilä 32M multi-fuel engines capable now of operating on methanol fuel and with ammonia ready notation. 

Wärtsilä will also supply the MethanolPac fuel storage, supply and control system, the gearboxes, two controllable pitch propellers (CPP), three bow thrusters, the NACOS navigation system, three Wärtsilä 20 auxiliary engines, and the hybrid electric system consisting of shore power, batteries, shaft generators, converters, transformers as well as the Energy Management System making it all work together.

Each vessel will also benefit from the Wärtsilä Hybrid Solution, optimising the fuel consumption today and allowing for future full green operation. The vessels will also be equipped with Wärtsilä shore power solution enabling carbon-free operations when the vessels are in port.

“These vessels are a further development of our previous cargo ship concepts where the focus on sustainability and future-proofing with multi-fuel combustion engines are prioritised,” says Per Westling, Managing Director of Stena RoRo. “With the help of Wärtsilä’s advanced technology, we intend to have the greenest Ro-Ro vessels on the market.”

“We are proud to be supporting these innovative hybrid vessels with our methanol fuelled engines and electrification systems. Both Stena RoRo and Wärtsilä share the same commitment to decarbonising shipping operations, and these vessels represent a further step in this direction by being the first methanol hybrid ships in their class. Not only will the emissions be minimised, but they will also have the most efficient energy utilisation during operations,” commented Roger Holm, President of Wärtsilä’s Marine Power business.

The 147 metre long ships will have 2,800 lane metre capacity and will be able to accommodate a total of 37 passengers and crew. They are scheduled for delivery in June and November 2025. The Wärtsilä equipment will be delivered to the yard in 2024.

Wärtsilä said it has a strong relationship with Stena RoRo, and as early as 2015 Wärtsilä converted the Stena Germanica to operate on methanol fuel. 

The two companies are currently cooperating on a number of other Ro-Pax projects.

China: CHIMBUSCO Jiangsu completes methanol bunkering operation in Taizhou

CHIMBUSCO Jiangsu on Tuesday (3 December) said it successfully refuelled the new methanol dual-fuel powered 1,300TEU container ship NCL VESTLAND at Taizhou Sanfu Marine Engineering.

The total amount of methanol bunker fuel delivered to the boxship was 79.5 metric tonnes.

CHIMBUSCO Jiangsu said the implementation of bunkering operation marked a major breakthrough for the company in the application of alternative fuels for ships, marking its ability to supply methanol marine fuel to ships on a regular basis.

A mobile methanol bunkering skid jointly developed by CHIMBUSCO Jiangsu and COSCO (Lianyungang) Liquid Loading & Unloading Equipment was used for the bunkering operation, which was successfully completed in 2.5 hours. 

In a separate statement, COSCO Shipping said the bunkering operation represented CHIMBUSCO Jiangsu’s first marine methanol fuel supply onshore.

The mobile methanol filling skid operates using the pump as its power source to facilitate simultaneous unloading and refuelling tasks. 

This skid includes several key functional modules, each of which is highly integrated. This integration ensures a safe and efficient process for transferring methanol fuel from tankers to a vessel’s fuel bunker, while also enabling seamless operation and intelligent management. 

The mobile methanol filling skid offers flexibility, requires low initial investment, and boasts a rapid bunkering rate of 180 cubic metres (m3) per hour. 

It stands as an optimal solution for methanol bunkering in the era before widespread adoption of methanol bunkering vessels. Additionally, it can provide bunkering support for shipyards to test new vessels and meet the bunkering requirements of the shipyard,” it added.

GAC: Does Sweden’s alternative fuel development risk worsening a maritime Catch-22?

Sweden leads Europe in developing alternative fuels, driven by its 2045 net-zero emissions target and the IMO’s 2050 decarbonisation goal, and it is now making bold advances in renewable fuel options for commercial shipping. 

It is also investing heavily in infrastructure to support the development of biofuels, liquefied biogas and natural gas, and synthetic fuels like eMethanol. Many of these projects, although relatively nascent, showcase the country’s bold vision to lead the alternative fuel development pack.

Groundbreaking

In May 2023, Sweden broke ground on the FlagshipONE facility in Örnsköldsvik, targeting annual production levels of 50,000 tonnes of carbon-neutral eMethanol by combining carbon dioxide and green hydrogen for commercial shipping.

In February 2024, Jämtkraft AB launched NorthStarH2, with the goal of producing up to 100,000 tonnes of eMethanol each year to support Sweden’s green electricity supply and maritime needs.

But the development of alternative fuels goes beyond eMethanol. In August 2024, ScanOcean partnered with Vegoil to introduce a marine fuel derived from hydrotreated vegetable oil produced in Sweden. The tanker vessel Key Fjord successfully took on that product as bunker fuel at the Port of Oskarshamn, marking a step towards making biofuels commercially viable for maritime use.

Such developments highlight Sweden’s leadership in the development of greener fuel options for maritime use. But supply issues could put the brakes on by limiting their market reach.

The risk of oversupply

Shipping faces a ‘Catch-22’ scenario with alternative fuels: low adoption limits the infrastructure development while companies delay investing in newbuilds or retrofits until fuel supply chains expand. 

This production-market access disconnect risks oversupply in Sweden’s alternative fuel market, restricting access to the wider European maritime sector.

Nils Igelström, Managing Director at GAC Sweden, highlighted the challenge of balancing production and demand for renewable marine fuels: "Sweden is producing some of the most advanced renewable marine fuels, but cargo owners are unwilling to pay higher freight costs. Without buyers, the environmental benefits remain unrealised, stalling progress towards decarbonisation."

Despite interest from shipowners, low demand highlights the need for better market access. 

“Companies like Preem, lead the development of alternative fuels, but oversupply persists,” added Igelström. “With heavily investments in refineries and fuel development, these facilities will continue producing fuels regardless of current demand. However, the priority now is ensuring these fuels reach the market effectively.”

Beyond the Baltic

Supply chain bottlenecks of alternative fuels, including logistical challenges and limited port infrastructure in other parts of Europe, hinder the export of surplus alternative fuels and can lead to higher costs and regulatory complexities. This uneven distribution particularly affects vessels that do not have easy or regular access to the North and Baltic seas. 

“If a vessel calls at Gothenburg regularly, fuel supply isn’t an issue,” said Igelström. “But in areas lacking necessary infrastructure, accessing Sweden’s alternative fuel supplies is challenging. With availability limited to Sweden or Finland or Germany, shipping companies hesitate to invest in greener vessels without certainty of supply.” 

Igelström also emphasised the need to improve accessibility across Europe to encourage investments and support the maritime sector’s green transition. 

The cost factor

Logistical challenges raise costs, with bunkering accounting for up to 50% of a vessel’s daily operating costs. Greener alternatives, according to the World Economic Forum, can cost up to four times more than traditional heavy fuel oil. For an industry with tight margins and volatile freight rates, zero-emission shipping significantly increases the cost of goods. 

A study by Drewry estimated that switching to green methanol would increase fuel costs by 350%, equivalent to an additional US$1,000+ per 40 feet container shipped from Asia to Europe.

“There is a big price gap between renewables and fossil fuels. Exporting Sweden’s alternative fuels further increases costs, but that’s a necessary step to achieve shipping’s green potential,” Igelström said.

Collaboration and clarity

Shipping thrives on clarity, but gaps in regulatory goals, infrastructure, and environmental policies hinder the development of an effective green fuel supply chain.

“Shipping companies need certainty,” Igelström noted. “With tight margins, they can’t risk fuel unavailability, especially where delivery points are scarce. Collaboration across Europe is essential to build a uniform supply chain that ensures renewable-powered ships can operate globally. Policymakers, industry leaders, and international organisations must unite to create conditions for renewable fuels to succeed.”

Sweden is working with partners in Finland, Iceland and the Faroe Islands, leading the charge in devising a supply chain that can support the maritime sector’s access to green fuels. 

In May 2024, the Nordic Maritime Transport and Energy Research Programme launched the STORM project to address supply barriers, assess fuel suitability, and propose solutions to accelerate the green transition. Sweden’s leadership in this initiative highlights its commitment to not only fuel development, but also market accessibility. 

“Sweden is doing its part to drive shipping’s fuel transition through fuel development and regulatory frameworks. However, Europe must collaborate to efficiently distribute surplus renewable fuels across the continent,” Igelström concluded.
