In its efforts to reduce the carbon footprint of its 90 vessel fleet, Solstad Offshore has turned to the technology group Wartsila for collaboration. The aim is to achieve a 50 percent reduction in CO2 emissions by 2030. Partnership is seen as being key to finding the right solutions.

The agreement aims to identify, evaluate, and implement solutions that will increase fuel efficiency and significantly reduce greenhouse gas emissions from Solstad offshore vessels. Each vessel will be assessed for appropriate solutions, possible operational improvements and life extension considerations. The company hopes to reach full carbon neutrality by 2050.

“Cooperation is essential if we are to implement the solutions needed to succeed with the green shift that is underway. For this reason, we at Solstad are partnering with forward-looking companies such as Wartsila who have the expertise, experience, and innovative technologies required,” says Tor Inge Dale, Head of Sustainability at Solstad Offshore.

“Solstad has a clear and ambitious strategy to become the owner and operator of the industry’s greenest fleet of vessels. We are happy and proud to have been selected to collaborate in this major decarbonisation project. Since no single solution will be relevant to every ship, by working together we intend to find what works best and most efficiently on a case-by-case basis. We see this as a blueprint for achieving the best possible results,” adds Cato Esperø, Head of Sales, Wartsila Norway.

Solstad has worked systematically to reduce emissions since 2009, both through operational measures, and technical upgrades. These have so far resulted in average fuel consumption per vessel being reduced by more than 20 percent. The further reduction to 50 percent is expected to be reached by optimising energy efficiencies, and by retrofitting the vessels to operate with alternative fuels such as hydrogen, ammonia, and methanol. Additionally, new ship designs must be capable of offering low or zero emissions from the outset.

Wartsila has industry-leading experience in developing and introducing new, environmentally friendly energy solutions for the maritime sector. Some 30 years ago, the company pioneered the use of LNG as a viable marine fuel, which has since been widely adopted.

The company has established itself as a pioneer in the testing of ammonia as a fuel for both marine engines and fuel cells. Wartsila has created a world first by successfully operating a combustion engine on a fuel mix with 70 percent ammonia content. It is currently developing capabilities to use even higher proportions of the fuel.

As a major participant in the EU’s ShipFC project, Wartsila is contributing to the development of the world’s first emissions-free offshore vessel operating with an ammonia-powered fuel cell. Furthermore, in 2021 Wartsila was awarded ‘Best of What’s New’ recognition in the engineering category by Popular Science magazine for its work within the MS Green Ammonia project. This new vessel concept will both transport and be fuelled by green ammonia.

“It is too early to determine which solutions will prove to be the most appropriate for meeting the GHG emission reductions envisioned by Solstad. However, it is extremely likely that future propulsion solutions operating with new alternative fuels, such as ammonia and/or methanol, will be key enablers as these fuels become widely available for bunkering,” says Roy H. Stavland, Senior Sales Manager at Wartsila.

Wartsila will initially be an advisor and technical expert to Solstad. The agreement also allows the company to act as a possible supplier for the decarbonisation solutions selected.

Daimler Truck reaches its next milestone on the road to sustainable transportation also with hydrogen-based drives. Since last year, a Mercedes-Benz GenH2 Truck fuel-cell prototype has been undergoing intensive testing – both on the in-house test track and on public roads. Daimler Truck is now putting another prototype into operation to test the use of liquid hydrogen. Political support for the development program comes from Daniela Schmitt, Minister of Economic Affairs of Rhineland-Palatinate, who opened the regional hydrogen week “WOCHE DES WASSERSTOFFS SÜD” with a test drive in Wörth am Rhein, Germany.

A newly installed prototype filling station at the development and testing centre in Wörth enables the refuelling with liquid hydrogen. Recently, Daimler Truck celebrated the first successful liquid hydrogen refuelling of the truck together with Air Liquide. During the refuelling process, cryogenic liquid hydrogen at minus 253 degrees Celsius is filled into two 40 kg tanks mounted on either side of the chassis. Thanks to the particularly good insulation of the vehicle tanks, the hydrogen can be kept at temperature for a sufficiently long time without active cooling.

Daimler Truck prefers liquid hydrogen in the development of hydrogen-based drives. In this aggregate state the energy carrier has a significantly higher energy density in relation to volume compared to gaseous hydrogen. As a result, more hydrogen can be carried, which significantly increases the range and enables comparable performance of the vehicle with that of a conventional diesel truck. The development objective of the series-ready GenH2 Truck is a range of up to 1,000 kilometres and more. This makes the truck suitable for flexible and demanding applications, especially in the important segment of heavy-duty long-haul transport. The start of series production for hydrogen-based trucks is planned for the second half of the decade.

Comprehensive commitment to hydrogen

At the same time, Daimler Truck is working together with Linde on the development of a new process for handling liquid hydrogen. Among other things, this innovative approach enables even higher storage density and easier refuelling compared to LH2. The companies plan for the first refuelling of a prototype vehicle at a pilot station in Germany in 2023. Daimler Truck and its partners are planning for a high level of transparency and openness around the relevant interfaces of the jointly developed sLH2 technology. The goal is to collaborate with other companies and associations as possible to develop their own refuelling and vehicle technologies that apply the new liquid-hydrogen standard and thereby establish a global mass market for the new process.

When it comes to infrastructure for hydrogen filling stations along important transport routes in Europe, Daimler Truck is planning to work together with the companies Shell, BP and TotalEnergies. Daimler Truck is also a shareholder in hydrogen filling station operator H2 MOBILITY Deutschland. In addition, Daimler Truck, IVECO, Linde, OMV, Shell, TotalEnergies and the Volvo Group have committed to work together to help create the conditions for the mass-market roll-out of hydrogen trucks in Europe as part of the H2Accelerate interest group.

On its path towards a CO2-neutral future Daimler Truck has clearly set its strategic course and is consistently pursuing a dual-track strategy in the electrification of its portfolio with both battery-electric and hydrogen-based drives. The ambition is to offer only new vehicles that are carbon-neutral in driving operation in its global core markets by 2039.

Mitsui O.S.K. Lines, Ltd., Tsuneishi Shipbuilding Co., Ltd. and Mitsui E&S Shipbuilding Co., Ltd. announced the launch of a joint project aimed at developing and building an ocean-going liquefied gas carrier that will use ammonia as its main fuel.

The vessel is envisioned as a mid-size ammonia/LPG carrier equipped with a main engine that can run mainly on ammonia, and targeting to achieve net zero carbon dioxide emissions while underway by using some of its ammonia cargo as fuel. This ship type is in the mainstream of ammonia carriers used for international maritime ammonia transportation, therefore, the vessel is able to call at major ammonia and LPG shipping and receiving ports around the world, meaning it can be used on a broad range of routes. The three companies continue to move toward the joint development and design of the ship, and plans delivery and introduction of the vessel around 2026 as the first “net zero emission ocean-going vessel,” as stated in “MOL Group Environmental Vision 2.1.”

In line with trends toward decarbonization, worldwide interest in ammonia fuel—which emits no CO2 during combustion—is growing as a next-generation clean energy source. So the move to strategically use ammonia as fuel has been accelerating in the maritime industry as
well. The three companies will offer clean ocean transport solutions with net zero emission vessels and play a part in comprehensive efforts to realize a decarbonized society, while anticipating and responding to rising demand for ocean transport of ammonia.

[Outline of the vessel]
LOA: About 180m
Breadth: About 30m
Draft: About 19m
Cargo tank capacity: About 40,000m3
Main engine: MITSUI-MAN B&W type S60 two-stroke dual-fuel ammonia engine
