Maritime Ammonia: ready for demonstration

Trevor Brown May 07, 2020

At least four major maritime ammonia projects have been announced in the last few weeks, each of which aims to demonstrate an ammonia-fueled vessel operating at sea. In Norway, Color Fantasy, the world's largest RORO cruise liner, will pilot ammonia fuel. Across the broader Nordic region, the Global Maritime Forum has launched NoGAPS, a major consortium that aims to deploy "the world's first ammonia powered deep sea vessel" by 2025. In Japan, a new industry consortium has launched that goes beyond on-board ship technology to include "owning and operating the ships, supplying ammonia fuel and developing ammonia supply facilities." And the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), which published its roadmap last month, aims to demonstrate ammonia fuel on "an actual ship from 2028" — specifically, a 80,000 dwt ammonia-fueled bulk carrier.

Hydrogen Filling Stations: techno-economic analysis of on-site ammonia reforming and H2 purification

Trevor Brown April 30, 2020

This month, a team of researchers from Fuzhou University in Fujian, China, published a new paper in the journal Sustainable Energy & Fuels that provides a “Techno-economic analysis and comprehensive optimization of an on-site hydrogen refuelling station system using ammonia.” The study concludes that “the H2 production cost of the NH3-fed on-site hydrogen refuelling station was at least 15% lower than other carbon-free routes (such as electrolysis, solar thermolysis, photo-electrolysis, etc.), and comparable to that of a methane steam reforming system with carbon capture and storage.”

Industry consortium announces feasibility study for co-firing ammonia in thermal power plants

Trevor Brown April 16, 2020

In March 2020, IHI Corporation, JERA Co., and Marubeni Corporation announced a feasibility study "to evaluate possible applications for the co-firing of ammonia in thermal power plants." The Japanese companies have contracted with NEDO to deliver detailed technical and economic analysis on the use of ammonia as a direct fuel for power generation. In addition, with support from Woodside Energy in Australia, they "will examine the construction and operation of world-scale ammonia facilities and the optimisation of supply chain costs" to support "large-scale export of hydrogen as ammonia."

Ammonia Included in Japan's International Resource Strategy

Stephen H. Crolius April 09, 2020

Japan’s Ministry of Economy, Trade and Industry has singled out ammonia for the role it can play in the country’s creation of a "carbon-free society." The news was embedded in METI’s New International Resource Strategy which was released on March 30. In the report's framing, ammonia is cited for its association with “the concept of importing renewable energy produced in other countries.” In a departure from the practice found in most reports on the energy transition, the ammonia discussion stands alone and not as one item on a roster of potential renewable energy vectors.

Literature Review: Ammonia as a Fuel for Compression Ignition Engines

Stephen H. Crolius March 23, 2020

The diesel engine, also known as the compression ignition (CI) engine, has been a workhorse of the modern energy economy for more than a hundred years. Its role in the coming sustainable energy economy will be determined by its ability to co-evolve with climate-friendly fuels. Two researchers from the National Institute of Advanced Industrial Science and Technology in Japan have now examined the fit between ammonia and the CI engine. Pavlos Dimitriou and Rahat Javaid arrive at a two-part conclusion in their paper, “A review of ammonia as a compression ignition engine fuel,” published in January in the International Journal of Hydrogen Energy. Part one is good news: “Ammonia as a compression ignition fuel can be currently seen as a feasible solution.” Part two is a dose of qualifying reality: to manage emissions of N2O, NOx, and unburnt NH3, “aftertreatment systems are mandatory for the adaptation of this technology,” which means that ammonia-fueled CI engines are likely to be feasible “only for marine, power generation and possibly heavy-duty applications where no significant space constraints exist.”

Environmental and Economic Assessment of Ammonia as a Fuel for Ships

Trevor Brown March 17, 2020

This month, the Korean Register published a comparative assessment of the environmental and economic merits of using ammonia as a maritime fuel. The work, written in collaboration with researchers at Pusan National University, is published in the open-access Journal of Marine Science and Engineering. It concludes that "ammonia can be a carbon-free fuel for ships," and presents "a meaningful approach toward solving GHG problems in the maritime industry."

Japan Advances SOFCs for the Built Environment

Stephen H. Crolius March 05, 2020

A steady stream of Japanese news reports over the last several months attest to the country’s progress in deploying fuel cells in the built environment. Dubbed “Ene-Farms,” the appliances function as micro-scale combined heat and power units, providing electricity as well as heat for domestic applications. Most of the Ene-Farms deployed so far feature proton-exchange membrane (PEM) technology (which requires high-purity hydrogen). However, two recent developments show that solid oxide fuel cell (SOFC) technology (well suited for ammonia) could play a role, maybe even a large role, in Japan's Hydrogen Society.
