Ammonia Energy Live April: low-carbon innovation at Hazer Group

Julian Atchison May 31, 2021

This April we presented a new episode in our monthly webinar series: Ammonia Energy Live. Every month we’ll explore the wonderful world of ammonia energy and the role it will play in global decarbonisation - with an Australian twist. For this episode we welcomed Geoff Ward, CEO of the Hazer Group. Hazer has been steadily developing their novel methane pyrolysis technique in Western Australia with a new low-carbon hydrogen production facility to begin construction later this year. Geoff joined us to reflect on Hazer’s journey so far, familiarise our audience with their processes and give his thoughts on what needs to be put in place for similar decarbonisation projects to succeed. And - of course - we asked Geoff where ammonia fits into Hazer’s future plans! Geoff was interviewed by Andrew Dickson (Development Manager of the Asian Renewable Energy Hub at CWP Global), and Darren Jarvis (Vice President of Strategic Project Development at Incitec Pivot).

Ammonia cracking: when, how, and how much?

Josh Makepeace

Cracking ammonia to produce hydrogen underpins many of the fuel-based uses of ammonia, and as such is a lynchpin technology in the case for ammonia energy. While in many ways ammonia cracking is a mature technology, systems which are designed specifically for these applications are less common. In this presentation, a general overview of the potential roles of ammonia cracking in facilitating the use of ammonia for energy applications will be outlined, including a survey of established and emerging cracking and purification technologies. A forthcoming project to produce an AEA Ammonia Cracking Technical Paper will be introduced.

Starfire Energy's ammonia cracking and cracked gas purification technology

Joseph Beach

Ammonia cracking is important for both combustion and fuel cell applications. Starfire Energy has verified that a blend of 70% ammonia + 30% cracked ammonia can burn well in a conventional natural gas burner with very low ammonia slip and acceptable NOx using a stoichiometric fuel-air mixture. A 10 MW turbine or internal combustion engine using such a blend will need about 1.44 tonnes of cracked ammonia per hour. Starfire Energy’s monolith-supported cracking catalyst may be ideally suited for this application. Fully cracked ammonia retains several thousand parts per million of ammonia due to thermodynamic limitations. Residual ammonia can damage…

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.”

Engie, Siemens, Ecuity, and STFC publish Feasibility of Ammonia-to-Hydrogen

Trevor Brown June 18, 2020

The UK’s Department for Business, Energy and Industrial Strategy (BEIS) recently published the feasibility study for its Ammonia to Green Hydrogen Project. This studies the techno-economic feasibility of importing green ammonia in order to supply large volumes of high-purity low-carbon hydrogen in the UK. The project has been designed and delivered by a heavyweight consortium of ENGIE, Siemens, Ecuity Consulting, and the UK’s STFC. The feasibility study, which is publicly available, represents the conclusion of Phase One of this project. Phase Two is demonstration: “to raise the TRL of a lithium imide based ammonia cracker from 4 to 6/7,” meaning that the technology is ready for deployment.

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.”

Ammonia Decomposition and Separation Using Catalytic Membrane Reactors

Sai P. Katikaneni Stephen N. Paglieri Aadesh X. Harale Aqil Jamal Koichi Eguchi Hiroki Muroyama Toshiaki Matsui

Hydrogen is the primary fuel source for fuel cells. However, the low volume density and difficulty in storing and transporting hydrogen are major obstacles for its practical utilization. Among various hydrogen carries, ammonia is one of the most promising candidates because of its high hydrogen density and boiling point and ease in liquefaction and transportation. The reaction temperature of ammonia cracking into nitrogen and hydrogen is about 500˚C or higher. The hydrogen can be effectively separated by the membrane based on Pd alloy about 500˚C. Currently, the extraction of hydrogen from ammonia is carried out by two step process involving…

HIAlba-IDEA: think tank launches in Scotland to deploy CSIRO technology, become green energy exporter

Trevor Brown April 04, 2019

NEWS BRIEF: A new policy think tank was launched last month that will focus on "why and how Scotland could benefit from being an early adopter of renewable hydrogen." Its "core starting point" is CSIRO's hydrogen-purification membrane, which enables ammonia to be used and exported as an efficient hydrogen carrier; for this use, green ammonia would be produced from offshore wind. According to the founders, this could lead to "Scotland becoming one of the largest global energy exporters in the world ... it could be the country’s main source of energy and create a knowledge economy."

Ammonia-to-Hydrogen System for FCEV Refuelling

Michael Dolan

Ammonia can play a significant role in fuelling the world’s growing fuel cell electric vehicle (FCEV) fleet through technologies which allow the decomposition of NH3, and subsequent extraction and purification of H2. CSIRO has recently demonstrated a pilot-scale ammonia-to-hydrogen system, incorporating an ammonia decomposition stage with a subsequent membrane-based hydrogen purification stage, at a rate of several kilograms of H2 per day. Through partnerships with an industrial gas producer and two FCEV manufacturers, the resulting H2 has been compressed and dispensed into FCEVs. System design, materials, performance and strategies for scale-up and demonstration will be discussed.
