Ammonia for Green Shipping Corridors

Decarbonization of shipping (responsible for 3% of global greenhouse gas (GHG) emissions) is a complex task due to the scale and complexity of the industry. However, it will not be possible to scale from day one and we need to start somewhere, and this is where Green shipping corridors play and important role. Yara, as the world’s largest ammonia distributor today, is partnering with several players to make this happen. In Scandinavia we have partnered with several players to build a network of ammonia bunkering barges and this summer we also signed a Collaboration Agreement with Pilbara Ports Authority (PPA)…

MAN Energy Solutions 2 stroke Ammonia engine

The marine industry is convinced that Ammonia is not only a very strong candidate as a future fuel, but also that Ammonia will be one of the leading future fuels. MAN Energy solutions has worked since 2019 on the development of a two stroke engine burning Ammonia by using the Diesel principle (as used for other fuels such as Methane , Methanol, Ethane and LPG) In this presentation, we will give an update on the engine design, which we will start testing in Copenhagen in Oct. 2022. The first ammonia engine (with final engine design and combustion process) is scheduled…

Nitrogen Reduction Reaction at High Current-to-Ammonia Efficiency

Apart from its use in the fertiliser and chemical industries, ammonia is currently attracting our community as a potential carbon-neutral fuel and as an energy carrier for worldwide transportation of renewable sources. To achieve this goal, replacements of the conventional hydrocarbon deposit-based technology for NH3 production require to be a green but inexpensive and scale-flexible technology, namely the only genuine electrochemical lithium-mediated nitrogen reduction reaction (Li-NRR). Reported by many research groups around the world, the process had so far been hampered by poor yield rates and efficiencies. At Monash University, we introduced a compact ionic assembly arranged in the electrode-electrolyte…

Global emissions implications from co-combusting ammonia in coal fired power stations: An analysis of the Japan-Australia supply chain

This study considers the emissions implications of co-combusting imported ammonia in coal-fired power stations. The study adopts a supply chain approach, estimating the emissions reduction potential of 20% ammonia co-combustion in coal-fired power stations in the country of use (Japan), and the emissions associated with ammonia production in the country of origin (Australia). The results show co-combustion of ammonia produced with SMR-HB provides no net benefit for the combined country emissions, as ammonia production related greenhouse emissions in Australia are equivalent to the emission reductions in Japan. In contrast, co-firing ammonia produced from fully renewable sources reduces emissions in the…
