The technology group Wärtsilä has initiated combustion trials using ammonia. The research will help the company to prepare for the use of ammonia as a fuel that can contribute to reducing both the shipping’s and energy sectors’ greenhouse gas emissions.

As part of the tests, ammonia was injected into a combustion research unit to better understand its properties. Based on initial results, the tests will be continued on both dual-fuel and spark-ignited gas engines. These will be followed by field tests in collaboration with ship owners from 2022, and potentially also with energy customers in the future.

“The first tests have yielded promising results and we will continue to optimise combustion parameters,” said Kaj Portin, General Manager, Fuel & Operational Flexibility, Wärtsilä Marine. “This is an important step in making sure that Wärtsilä can provide the engine and fuel systems that ship owners need, whichever fuel they choose in the future.”

Ammonia is a promising, carbon-free fuel as shipping explores how to fulfil the International Maritime Organization’s vision of reducing greenhouse gas emissions from shipping by at least 50% by 2050, while the energy sector is developing optimal paths for 100% renewable energy systems already today. Although ammonia is derived mainly from fossil sources today, in the future ammonia’s greenhouse gas footprint can be nearly eliminated if it is produced using electricity from renewable sources.

The tests are just the latest step as Wärtsilä aims to develop a complete ammonia fuel solution comprising engines, fuel supply and storage. The company is working with ship owners, shipbuilders, classification societies and fuel suppliers to learn more about system and safety requirements, as well as fuel composition, emissions and efficiency.

Wärtsilä is developing ammonia storage and supply systems as part of the EU project ShipFC to install ammonia fuel cells on Eidesvik Offshore’s supply vessel Viking Energy by 2023. The company has also gained significant experience with ammonia from designing cargo handling systems for liquid petroleum gas carriers, many of which are used to transport ammonia.

Ammonia has a number of properties that require further investigation. It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process. A regulatory framework and class rules will need to be developed for its use as a marine fuel.

Wärtsilä is investigating several future fuels, including synthetic methane, ammonia, hydrogen and methanol, with a view to providing complete flexibility across engines and the fuel chain. Internal combustion engines can be adapted to burn any fuel. Dual-fuel or spark-ignited engines are already capable of burning liquified natural gas – from fossil, biomass or synthetic sources – while diesel engines can run on liquid biofuels, biodiesel or e-diesel.

Wärtsilä has extensive experience in converting engines to other fuels, including diesel to dual-fuel, as well as engines capable of burning methanol and volatile organic compounds from crude oil cargoes. The modularity of modern engines means that conversions can be made with a very limited exchange of components. Wärtsilä’s investment in modular engines and in storage and supply systems will enable shipping’s transition from current fossil fuels to bio- and synthetic fuels.

The Global Centre for Maritime Decarbonisation GCMD and MOL announced the signing of a five-year Impact Partnership agreement. On the same day, both parties held a signing ceremony at the GCMD office in Singapore.

Decarbonisation in the maritime industry is a challenge that needs to be achieved through accelerating collaboration and increasing investment by shipping companies, their customers, ports, energy suppliers and public sector actors. As an Impact Partner of GCMD, MOL will utilise its expertise developed over their long history and make various contributions and collaborations through its participation in GCMD’s projects, including providing access to vessels, operating data and evaluation reports so that internal learnings can be shared publicly and used for future trials.

MOL is one of the world’s leaders in the maritime industry and has been leading worldwide discussions on achieving decarbonisation. The carbon budget concept imposes a ceiling to the cumulative amount of greenhouse gas (GHG) that can be emitted globally in order to limit global temperature rise to 1.5 degree Celsius by 2050. Intermediate targets to reduce emissions, in addition to a net-zero target, are necessary. While plans are in place to adopt low or zero emissions vessels in the future, it is important to deploy measures to reduce emissions now. Such measures include the use of low-carbon and transition fuels that are available today, and deploying energy savings devices onboard vessels. MOL will bring its extensive capabilities and experience to bear as it joins GCMD and existing partners to accelerate international shipping’s decarbonisation.

Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation, said: “We are proud to have MOL, one of the leading shipowners in Japan, come onboard as an Impact Partner. We are excited to tap on MOL’s track record in developing technical energy efficiency measures to broaden our perspective as we scope an initiative to help increase industry adoption of measures that can increase fuel efficiency of ships.”

Toshiaki Tanaka, Representative Director, Executive Vice President Executive Officer, and Chief Operating Officer of MOL, said: “We are very pleased to be a partner of one of the most important global coalitions. We will make our biggest effort to contribute and accelerate progress towards the net zero future in maritime industry, together with GCMD and all its partners.”

Hapag-Lloyd has entered into a partnership with DB Schenker for the purpose of decarbonising supply chains. Following the launch of “Ship Green” in May, the renowned logistics provider has selected Hapag-Lloyd’s sustainable transport solution as part of its sustainability initiatives.

DB Schenker and Hapag-Lloyd have signed an agreement for emission-reduced container transports with a waste- and residue-based biofuel. By end of 2023, DB Schenker plans to claim approximately 3,000 metric tonnes of carbon dioxide equivalent (CO2e) emissions avoidance. This is based on at least 1,000 tonnes of pure biofuel.

“We are excited about this new partnership with DB Schenker as we share the common goal of making logistics more sustainable. Collaborations like these set a clear signal in the industry and are another example of a step-by-step approach to further decarbonise supply chains”, said Henrik Schilling, Managing Director Global Commercial Development at Hapag-Lloyd.

“I am very pleased that together with Hapag-Lloyd we are setting another example for sustainability in our industry. This partnership further enlarges our global biofuel offer in ocean freight. With this commitment we are one step closer to our goal of becoming carbon-neutral”, said Thorsten Meincke, Global Board Member for Air & Ocean Freight at DB Schenker.

Hapag-Lloyd has launched the Ship Green product to offer its customers emission-reduced ocean transports. Based on biofuel, customers of Hapag-Lloyd can add Ship Green as an additional service to their existing bookings – thereby avoiding CO2e emissions. Using the so-called “Book & Claim” chain of custody, Hapag-Lloyd can attribute avoided emissions to all ocean-leg transports, regardless of the vessel and route used. Ship Green is available for all shipments containing standard, hardtop or tank equipment. By offering Ship Green, Hapag-Lloyd is continuing along its path towards achieving climate-neutral fleet operations by 2045.

EU Member States cleared the way to bring sustainable renewable fuels into maritime transport. They approved the “FuelEU Maritime” regulation. The EU Parliament had also voted in favour of the agreement reached in the trilogue procedure.

The new requirements will apply to ships with a gross tonnage of more than 5,000 entering, leaving or staying in ports in the territory of an EU Member State. In addition, shore-side electricity will be mandatory for container and passenger ships from 2030. The use of synthetic fuels from renewable energies will be specifically promoted for shipping.

Federal Minister of Transport Dr Volker Wissing:
After we were recently able to achieve a breakthrough for maritime climate protection at UN level, we are now pushing the actual transformation towards climate-neutral shipping at European level with the “FuelEU Maritime” initiative. The draft regulation is open to technology and takes into account the special competitive conditions in the maritime transport sector. The main objective is to increase the demand for renewable and low-carbon fuels and their consistent use, thereby decisively reducing greenhouse gas emissions in maritime transport. The initiative is thus expected to play a fundamental role in the implementation of the European Climate Change Act for shipping.

Federal Environment Minister Steffi Lemke:
Today the EU has set a decisive course for more climate protection and the use of renewable fuels in maritime transport. Shipping companies will continue to rely on fuels in the future, because electric drives are not yet an option for long-distance transport. In maritime transport, e-fuels from renewable energies are therefore a sensible climate-friendly alternative. With the new requirements, the EU is giving manufacturers and shipping companies the necessary planning security, driving forward the development of modern technologies and making renewable fuels for maritime transport ready for the market. But there are also shadows: The fact that fuels from fossil sources and nuclear energy are also permitted as a compliance option is regrettable. The German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) will continue to advocate the use of predominantly synthetic fuels from renewable energy sources in order to make maritime transport climate neutral.

FuelEU Maritime lays down uniform EU-wide rules for limiting the greenhouse gas intensity of the energy used on board a ship, and thus above all the fuels. The regulation from the Fit for 55 package stipulates that shipping in the EU must reduce its emissions by 2 percent from 2025, 6 percent from 2030, 14.5 percent from 2035, 31 percent from 2040, 62 percent from 2045 and 80 percent from 2050. The GHG intensity reduction targets are set against the 2020 average GHG intensity of energy consumed on board ships. The greenhouse gas emissions of all fuels are assessed on the basis of a life cycle assessment (so-called well-to-wake (WtW) approach that includes the greenhouse gases carbon dioxide, methane and nitrous oxide). All fuels are permitted as a compliance option; the legislative initiative is thus technology-neutral.

The use of synthetic fuels is encouraged by a special mechanism: if the share of synthetic fuels from renewable energy sources (so-called “renewable fuels of non-biological origin, RFNBO) in the fuel mix does not exceed one percent in 2031, a mandatory minimum quota of two percent for these RFNBO fuels will automatically come into force from 2034. Beyond the use of alternative fuels, the FuelEU Maritime Regulation obliges container and passenger ships in ports in the territory of a Member State to use shore-side electricity or alternatively zero-emission technologies for on-board energy supply.

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. It shall apply from 1 January 2025, with the exception of certain Articles which shall apply from 31 August 2024.
