US Senators Show Strong Interest in Ammonia-Fueled Shipping

Jonathan Lewis October 08, 2020

The Senate Energy and Natural Resources Committee, led by Chairman Lisa Murkowski (R-Alaska) and Ranking Member Joe Manchin (D-West Virginia), recently hosted a hearing on offshore energy technologies. I was invited to testify on technology and policy options for eliminating greenhouse gas emissions from the marine shipping sector, and I used the opportunity to spotlight ammonia's central role in that effort.

Picking bunker winners: the mono-fuel / dual-fuel duel

Trevor Brown September 24, 2020

This week, DNV GL published its annual Maritime Forecast to 2050, concluding that “e-ammonia, blue ammonia and bio-methanol are the most promising carbon-neutral fuels in the long run.” DNV GL’s assumptions that determine this long run, however, suggest a significant mid-term reliance on fossil LNG. This risks locking the industry into a long-term emissions trajectory incompatible with the IMO’s 2050 GHG targets, in part because of significant fuel supply and infrastructure investments. These investments could become more ‘sticky’ than expected. A host of alternative opinions have been published in the days before and after DNV GL published its report. These suggest that, for ammonia, the long run could begin this decade. Among others, MAN ES has announced that its ammonia engine will be available for retrofits by 2025.

Japan's NYK and partners to develop ammonia fueled and fueling vessels

Trevor Brown September 17, 2020

In recent weeks, the Japanese shipping company NYK Line has announced a series of high-profile research and development collaborations that aim to establish ammonia fueled vessels and fuel supply. Its partners in these projects include classification society Class NK, engine manufacturer IHI Power Systems, and shipbuilder Japan Marine United Corporation. Three vessel types have been announced, so far, including an ammonia-fueled ammonia gas carrier, an ammonia barge for offshore bunkering, and an ammonia-fueled tugboat (for navigating the barge). Pushing beyond the initial research phase, these collaborations aim for commercialization and to put these vessels “into practical use.”

Ammonia as a future marine fuel - bunkering safety and potential issues

Koh Eng Kiong

Bunkering is an indispensable operation to supply fuel to ships. Currently in marine industry, ammonia has been a bulk commodity frequently loaded/unloaded from terminal to ship or ship to terminals. The operation is similar to bunkering, the difference being that ammonia is transferred to a dedicated storage tank instead of fuel tank. The future adoption of green ammonia as a marine fuel will need to be developed taking reference of the existing industry practice, of which the bunkering operation is carried out for heavy fuel oil, diesel oil, marine gas oil, lube oil and LNG. There is also a need…

How to get approval of an ammonia fuelled vessel

Rene Laursen

“How to get approval for an ammonia fueled vessel” It is well known that ammonia as a fuel is inherently carbon and sulphur free. Compared to fossil fuels, combustion of ammonia reduces CO2, CO, particulates/soot, unburnt hydrocarbons and sulphur oxides by at least 90%. With ongoing research and development to investigate the modifications needed for existing marine diesel engines to combust ammonia, there is a potential of fast adoption by the maritime industry through new builds and perhaps also through retrofits. Today, there are no prescriptive rules and regulations in place for the use of ammonia as fuel in marine…

Haldor Topsøe and Partners Issue Ammonfuel Report

Stephen H. Crolius August 20, 2020

Earlier this month Haldor Topsoe and four partners issued Ammonfuel - an industrial view of ammonia as marine fuel. According to the accompanying press release, the 59-page report provides “a comprehensive and up-to-date overview of the applicability, scalability, cost, and sustainability of ammonia as a marine fuel.” The partners include Vestas, Siemens Gamesa, Hafnia, and Alfa Laval.

Wärtsilä, Repsol, and Knutsen to test ammonia four-stroke engine

Trevor Brown July 01, 2020

This week, engine manufacturer Wärtsilä announced “the world’s first long term, full-scale, testing of ammonia as a fuel in a marine four-stroke combustion engine.” The project will begin in the first quarter of 2021, at the Sustainable Energy Catapult Centre’s testing facilities at Stord, Norway. It is supported by a NOK 20 million (USD 2 million) grant from the Norwegian Research Council.

Maersk and partners launch Center for Zero Carbon Shipping

Trevor Brown June 25, 2020

This morning, the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping was announced. Launched with a “start-up donation” of DKK 400 million (USD 60 million) from the A.P. Møller Foundation, this new research institute intends “to develop new fuel types and technologies,” to decarbonize the maritime sector. Behind the Center for Zero Carbon Shipping is a significant industrial consortium with seven founding members (actively seeking additional partners): ABS, A.P. Moller – Maersk, Cargill, MAN Energy Solutions, Mitsubishi Heavy Industries, NYK Lines, and Siemens Energy.

Vopak joins Itochu on feasibility of ammonia fueling at Port of Singapore

Trevor Brown June 17, 2020

Last week, Itochu Corporation announced an agreement with Vopak, the oil and chemical storage tank and terminal operator, "to jointly study the feasibility of developing an infrastructure" at Vopak's Banyan Terminal, leading to the "establishment of supply chain of ammonia marine fuel in Singapore."
