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.

A Deep Dive into SIP "Energy Carriers" Ammonia Combustion Research

Bunro Shiozawa September 23, 2020

From 2014 to 2018 Bunro Shiozawa served as Deputy Program Director of the SIP “Energy Carriers” initiative in Japan. Over the last year he has published a ten-part series of articles that describe and reflect on the research supported by the initiative. Part 4 covers ammonia combustion technologies. The first half of the article follows, in Shiozawa's English translation. The second half will be posted in the near future.

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.”

New IEA Report: One Take on the Sustainable Energy Economy

Stephen H. Crolius September 17, 2020

Last week the International Energy Agency released Energy Technology Perspectives 2020. The report has an upbeat tone, envisioning a high degree of feasibility for the development and deployment of relevant technologies. For those working in the sustainable energy field, though, the aspect of greatest interest may be the relative weights placed on fossil fuels, bioenergy, and hydrogen.

Communique from the AEA Australia 2020 conference

John Mott September 09, 2020

AEA Australia’s second annual Ammonia = Hydrogen 2.0 conference took place at the end of August, hosted virtually by Monash University with the support of CSIRO. Alan Finkel, Australia’s Chief Scientist, gave the opening address, “Ammonia — is it a fuel, or is it an energy carrier?” The conference keynote speech was given by Rob Stevens of Yara, entitled “The role of Ammonia in a hydrogen economy.”

Series Presents Japanese Perspective on Ammonia as a CO2-Free Fuel

Bunro Shiozawa September 08, 2020

From 2014 to 2018, I served as Deputy Program Director of SIP “Energy Carriers” under Mr. Shigeru Muraki, Program Director, and alongside my fellow Deputy Program Director, Dr. Ken-ichi Aika. After helping to bring the Energy Carriers' work to a successful conclusion, I decided to write a series of articles that describe prospects for ammonia as a CO2-free fuel and hydrogen carrier, as well as activities to construct a value chain of CO2-free ammonia. The articles were published in the on-line journal of Japan’s International Environment and Economy Institute (IEEI).

Hyundai joins Fortescue and CSIRO to "fast track" ammonia to high-purity hydrogen system

Trevor Brown September 03, 2020

Fortescue recently announced that it has signed a memorandum of understanding (MOU) with Hyundai Motor Company and CSIRO for the “development and future commercialisation” of its metal membrane technology. This technology, which produces high-purity compressed hydrogen from liquid ammonia, was demonstrated in 2018. It enables PEM fuel cell vehicles to refuel using hydrogen that is generated on demand from ammonia. At scale, this technology could enable an ammonia-based hydrogen production, storage, and distribution infrastructure, lowering the barriers to implementation of a national network of hydrogen filling stations. Now, “Hyundai will seek to demonstrate the viability of the technology for renewable hydrogen production and vehicle fuelling in Korea.”

EPRI, GTI Launch Low-Carbon Initiative

Stephen H. Crolius September 03, 2020

Last month the Electric Power Research Institute (EPRI) and the Gas Technology Institute (GTI) announced a new undertaking: the Low-Carbon Resources Initiative (LCRI). According to the organizations’ press release, over the next five years they will work together and with collaborating companies to “accelerate the development and demonstration of low-carbon energy technologies.”

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.

Zero emission aircraft: ammonia for aviation

Trevor Brown August 20, 2020

This week, Reaction Engines announced a “ground-breaking study” on ammonia as a fuel for zero-emission aircraft. This will soon be followed by a demonstration project, “integrating the technology into a ground-based test engine.” The study combines Reaction Engines’ heat exchanger technology with the ammonia cracking technology being developed by the UK’s Science and Technology Facilities Council (STFC). By partially cracking green ammonia to hydrogen, the resulting ammonia fuel mix “mimics jet fuel,” making it possible to adapt existing engines and aircraft to use zero-emission fuels. “This means a fast transition to a sustainable aviation future is possible at low cost.”
