The so-called lithium redox-mediated nitrogen reduction reaction presents the only known process enabling genuine electrochemical conversion of N2 to ammonia. Notwithstanding the rapidly increasing investigative efforts, the commonly reported performances of the Li-mediated N2 electroreduction, viz. yield rate, current-to-ammonia (faradaic) efficiency and durability in operation, still pertain to the domain of academic research rather than practical development. Our most recent work focused on redesigning the key components of the electrolytic N2 reduction cell enabled breakthroughs in all the key metrics of the process. Specifically, we have introduced a stable proton shuttle based on the phosphonium cation that delivers protons to…

The quickfire presentation will focus on the direct use of ammonia as an energy carrier. The examples considered here include using ammonia in diesel engines for power generation applications and development of solid oxide fuel cells operating with ammonia.

Australia is lucky. We have bountiful natural resources, buried in the ground, streaming from the sun and coursing through the air. Along with our geographic position on the apex of the vast Asian Pacific trade route we are in the perfect situation to initiate a new industry.   Oceania are connecting together these key aspects of Australia’s DNA. Our ambition is to leverage the abundant energy sources in the north-west of Australia to supply green ammonia, then utilise the best-in-class bunker vessel to deliver sustainable shipping fuel to an industry that’s responsible for 3% of global GHG emissions. To achieve…

To deploy green ammonia projects at the scale and speed required to meet decarbonisation targets, we have to revisit conventional methods. There are numerous challenges in coupling renewable energy with ammonia production. This presentation proposes to use ‘Reference Plants’ as building blocks to closely couple green hydrogen and green ammonia plants.

The move to production of green ammonia using hydrogen produced from renewable energy raises the need to manage a variable production of hydrogen with a demand that has traditionally been constant 24/7. Whilst ammonia plants have some ability to ramp production rates, there are limits to this and any operation at reduced capacity will mean that their annualized cost recovery must be amortised over reduced production. Thus there is an apparent need for buffer storage corresponding to one or two days of hydrogen feedstock. This talk will introduce a new approach to underground storage of hydrogen that is being commercialized…

The Smart Energy Council has established a world leading zero carbon certification for renewable hydrogen, renewable ammonia and renewable metals. This overview of the scheme will include results of the first project being certified under the scheme and the current pre-certification of the Yara renewable ammonia plant being built in the Pilbara, Western Australia.

As green and blue ammonia begin to be utilized as a zero-carbon marine fuel, we will see the need for substantial infrastructure development to support the demand. The green and blue ammonia value chains differ in the hydrogen production method used; green ammonia being generated from water electrolysis and blue ammonia being generated from a conventional pathway, using natural gas, but with the addition of carbon capture. The level of commercialization and the relative total installed costs for green and blue ammonia plants will be discussed.

Ammonia as a Marine fuel is a new introduction to the Bunker industry. In order to be better prepared for setting up the required infrastructure etc for an efficient supply chain, it is important to understand what are the downstream challenges that suppliers can expect. A key aspect of this is to hear it from potential end-consumers and gain their perspective. Maersk is committed to reducing its Co2 emissions by almost 60% (over Y2008 baseline) by 2030 and is exploring Ammonia as a possible pathway to get there. This session will address challenges foreseen in adopting Ammonia by a Dry…
