Fortescue’s ammonia locomotive one step closer

R&D for ammonia-powered locomotives is full steam ahead in Perth, as Fortescue Future Industries moves onto converting two four-stroke, diesel locomotives to run on ammonia fuel. Deployment of an ammonia-powered demonstration locomotive within their current rail operations is planned for later this year. In other FFI news this week, a technical feasibility study has given the thumbs up for FFI to convert Incitec Pivot's existing Gibson Island ammonia production plant to a green ammonia facility, and a new agreement between Australian energy giant AGL and FFI will see the pair turn the current Liddell and Bayswater coal power stations into a huge green hydrogen hub near Newcastle, NSW.


Piloting a Combined Heat and Power / Distributed Generation System, Powered by Carbon-Free, Renewable-Based Anhydrous Ammonia

UCLA-STPP is an interdisciplinary science / policy research unit, enjoining faculty in schools of engineering, public health, law, business, and medicine. The two-part mission of UCLA-STPP is to: (1) evaluate the viability of safer, cleaner, greener, more sustainable substitutes for existing hazardous services, processes, systems, and/or technologies, and (2) employ diffusion analysis to identify institutional, policy, and regulatory barriers to the adoption of viable safer substitutes and prescribe policy changes to overcome key barriers. UCLA-STPP has taken leadership in developing and institutionalizing “alternatives analysis” as policy/regulatory tool as a method to evaluate and identify safer, cleaner, greener, more sustainable substitutes.…


A Hybrid Vehicle Powered by Hydrogen and Ammonia

A partnership of Research and Industry entities has developed a fully working hybrid electric vehicle equipped with a 15 kW IC engine fuelled with liquid ammonia as a range extender of the lithium batteries pack on board. The entire vehicle powertrain (ie, the IC engine, the electric generator coupled with the engine, the electric motor, the electronics etc.) has been studied and designed. Regarding the IC engine, as is known, ammonia combustion is characterized by a high activation energy and a low flame velocity, therefore a small amount of hydrogen is requested as igniter and combustion promoter. The necessary amount…


Making and Treating NOx formed in NH3 Engines

Ammonia has real promise as a green renewable fuel; however its use is not without some of the drawbacks endemic to high temperature combustion processes. Chief among them is the potential for NOx formation in nitrogen-rich oxidizing environments. Nitric and nitrous oxides are prime culprits that plague both entrenched hydrocarbon internal combustion technology but also emerging technologies like ammonia-as-a-fuel. Nitric oxide is implicated in photochemical ground-level ozone production in urban areas. Nitrous oxide is its own double-edged environmental sword, being both a potent tropospheric green-house gas as well as a principle agent in renewed stratospheric ozone-depletion (Science 2009, v326, p.…
