Ammonia bunkering - simulation of hypothetical release scenarios in Singapore
Presentation

Ammonia bunkering - simulation of hypothetical release scenarios in Singapore

Liu Ming

Ammonia has the potential to be a low carbon fuel for shipping. As an important step for ships to adopt the fuel, the bunkering operation of ammonia shall be established. Ammonia bunkering can be characterized by different infrastructure and operation requirements from that of conventional marine fuel. The study presents potential bunkering concepts and configurations. The dispersion pattern due to accidental ammonia release is investigated by far-field simulation using PHAST software. The impacts of various factors on the dispersion patterns are explored to provide preliminary understandings of future ammonia bunkering safety in Singapore. Slides: please see the attached file.

Certifying renewable ammonia

Certifying renewable ammonia

Scott Hamilton

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.

Highlights from the EU debate on H2 certification

Highlights from the EU debate on H2 certification

Raffaele Piria

Climate mitigation is key driver for H2 roadmaps and policies. Regulatory framework still in its infancy, but it will evolve dynamically. In 1st phase, H2 GHG emission (and other sustainability) standards must take into account the still high level of power sector emissions in EU and elsewhere, and the need to get the clean H2 market up and running. But in the medium term, GHG emission standards will get closer and closer to true climate neutrality. I personally would anticipate this and would not advise to make long term investments in “grey-green” or “grey-blue” H2 => It might be accepted…

Hydrogen Certification

Hydrogen Certification

Fiona Simon

The ability for consumers to have certainty with regard to the origin of their energy products is crucial if Australia is to meet its potential to be a top exporter of clean hydrogen. The hydrogen industry is on a journey towards the development of a certification scheme to allow this. Alignment on key concepts and close engagement with the Federal Government has allowed the industry to progress towards a scheme which will meet the needs of producers and consumers. The process to date could provide a blueprint as ammonia producers embark on the same journey.

A new hydrogen storage technology for buffering the input to green ammonia plants

A new hydrogen storage technology for buffering the input to green ammonia plants

Keith Lovegrove

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…

Ammonia trade and embedded emissions pricing

Ammonia trade and embedded emissions pricing

Emma Aisbett

Emissions (carbon) pricing has been theoretically and empirically proven to be the most efficient means of correcting the market failure caused by greenhouse emissions externalities. None-the-less, political constraints have prevented emissions pricing from forming a stable component of Australian climate and energy policy. For export-facing industries such as ammonia, however, emissions pricing in export markets is likely to matter more than Australian policy. In particular, the European Commission is set to propose a carbon-border adjustment mechanism in July 2021. The US is also considering ways of ensuring their industries are not disadvantaged as a result of its substantially ramped up…
