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.

Ammonia, Hydrogen P2X2P Demonstrations Slated for Europe

Stephen H. Crolius May 28, 2020

At this early point in the energy transition, many groups are formulating big-picture concepts for the design of a sustainable energy economy, and many more are developing discrete technologies that will be relevant as the transition advances. The multi-stakeholder H2020 European project known as “FLEXibilize combined cycle power plant through Power-to-X solutions using non-CONventional Fuels” (FLEXnCONFU) is coming from a different direction. Its premise is that construction of a bridge to the future should start now, and should be anchored in aspects of the current energy system that are likely to endure over the long-term.

Ammonia Combustion and Public Perception

Albert Lanser

Introduction Duiker Combustion Engineers is located in Wateringen-NL (main office) and has a branch office in Beijing (PRC). The core business of Duiker Combustion Engineers consists of development, engineering, supply & servicing of combustion- & process equipment. Duiker is market leader in the engineering & supply of combustion equipment for sulphur recovery units (SRU’s) in oil refineries & gas treatment plants. Combustion of ammonia In recent years, the stoichiometry-controlled oxidation (SCO) concept has been developed by Duiker Combustion Engineers to handle the ammonia-rich streams from sulphur recovery units within refineries. Several full-scale commercial SCO units have already been designed, delivered,…

Cardiff University Launches Ammonia Gas Turbine Project

Stephen H. Crolius April 23, 2020

Last week Agustin Valera-Medina, Associate Professor at Cardiff University in the United Kingdom, told Ammonia Energy that work is underway on a £1.9 million (USD $2.3 million) project that will advance the frontiers of ammonia-gas turbine (AGT) technology. Valera-Medina is serving as the Principal Investigator of the Storage of Ammonia for Energy (SAFE) – AGT Pilot, a four-year effort that hopes to develop “a unique, competitive technology that can be implemented to support the hydrogen transition.”

Analysis of an Ammonia/Ammonium Nitrate Fuel's Thermal Decomposition By Mass Spectrometry and Thermogravimetric Analysis

Bar Mosevitzky Gennady E. Shter Gideon S. Grader

Research on renewable synthetic fuels has become a hot-topic in recent years. This is due to the long-term energy storage capabilities of chemical bonds and their potential compatibility with current energy infrastructure. Specifically, nitrogen-based fuels offer a carbon-free solution to wide scale implementation of renewable energies. Therefore, the inherent chemistry involved in the utilization of these fuels for stationary and mobile power generation is of prime interest. Unlike ammonium nitrate, ammonia suffers from unstable combustion characteristics. Therefore, adding ammonium nitrate to ammonia combustion may stabilize the process. However, while ammonia’s gas-phase reaction mechanism is well studied, ammonium nitrate’s is poorly…

Ignition Delay Times of Diluted Mixtures of Ammonia/Methane at Elevated Pressures

C. Filipe Ramos Bo Shu Ravi Fernandes Mário Costa

The present worldwide concern with global warming has stimulated the development of carbon-neutral energy technologies in order to mitigate the need of fossil fuels and the emission of greenhouse gases. In this sense, ammonia (NH3) is regarded as one of the most viable alternatives to produce carbon-free energy, presenting high energy density and ease of storage and handling [1]. Furthermore, due to the long-lasting use of ammonia in the fertilizer and refrigerant industries, its possible implementation as a fuel presents an unmatched economic feasibility, when compared to other carbon-free alternatives [2]. However, ammonia has proven to be more resilient to…

Duiker Combustion Engineers BV Stoichiometry-Controlled Oxidation (SCO) Technology for Industrial Ammonia Combustion

Albert Lanser

In recent years, the stoichiometry-controlled oxidation (SCO) concept has been developed by Duiker Combustion Engineers to handle the ammonia-rich streams from sulphur recovery units within refineries. These ammonia rich streams are considered as waste streams that need to be destroyed with low NOx emissions. Several full-scale commercial SCO units have already been designed, delivered, installed and put in operation on refinery sites across the world, firing pure ammonia or rich ammonia-containing flows. The SCO technology has been based upon staged combustion and turns out to be a robust process, which is easy to operate and responds fast to upset conditions.…

Ammonia in the Mix as an Industrial Energy Source

Stephen H. Crolius October 25, 2019

ANNUAL REVIEW 2019: The generation of heat for industrial processes accounts for approximately 10% of global greenhouse gas emissions – which means that finding ways to eliminate this climate footprint is among the pressing technology tasks on our societal to-do list. Developments over the last 12 months suggest that ammonia could play an important role in meeting this challenge.

IHI Corporation pushes its ammonia combustion technologies closer to commercialization

Trevor Brown October 11, 2019

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)." Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.

Maritime ammonia engines in Japan; ammonia shipbuilding in South Korea

Trevor Brown September 27, 2019

This week, Japan Engine Corporation (J-ENG) announced the launch of a new R&D program, in collaboration with the National Maritime Research Institute, that focuses on engine development for "combustion of carbon-free fuel (e.g. hydrogen and ammonia)." Five hundred miles across the Sea of Japan, DSME has completed a techno-economic feasibility study comparing three fuels: HFO (with scrubber), LNG, and ammonia. The results of this study will be presented at the Ammonia Energy Conference, in Orlando, FL, on November 13. DSME is one of the three big shipbuilders in South Korea, and its business case for ammonia is strong enough that now "DSME is planning to expand our technology and business to NH3 engineering and systems for commercial ships."
