South Australia Planning Hydrogen Export Strategy

The state of South Australia earlier this month issued a tender for professional services under the title “Hydrogen Export Study, Modelling Tool and Prospectus.” The tender is a further step in the state’s campaign to become a major exporter of renewable energy in the form of green and/or blue hydrogen. The results of the study are expected to “inform key considerations such as locations for hydrogen production and export, volume of supply potential, the interdependencies of hydrogen supply chain infrastructure, and the landed cost of clean hydrogen exported from South Australia.”

H2U moves forward with 3 GW green ammonia export plant

According to a statement released by the Queensland government last week, the clean infrastructure development firm Hydrogen Utility (H2U) has purchased a 171-hectare site in Gladstone, Queensland, where it intends to build a green ammonia export plant with initial operations beginning in 2025. This "H2-Hub" will be built in stages, scaling up over time to reach up to 3 GW electrolyzer capacity for green hydrogen production, and up to 5,000 tons per day of green ammonia. This is at least twice the size of a conventional natural gas-based world-scale ammonia plant.

Royal Society publishes Green Ammonia policy briefing

This week, the UK's Royal Society published an influential "Green Ammonia" policy briefing on ammonia as a "zero-carbon fertiliser, fuel and energy store." Rather than provide a comprehensive summary here — the Royal Society policy briefing is freely available to download — I want to focus only on four specific figures. These four illustrations repackage previously available data in valuable new ways, communicating key insights around the barriers to and opportunities for ammonia energy.

Australia Issues National Hydrogen Strategy

Last month the Council of Australian Governments Energy Council – “a Ministerial forum for the Commonwealth [of Australia], states and territories and New Zealand, to work together in the pursuit of national energy reforms” – issued a 137-page report entitled Australia’s National Hydrogen Strategy. For those focused on how ammonia energy will go from promising idea to practical reality, this is what the next step – the one after the discovery of ammonia's virtues as a hydrogen carrier – could look like. The Strategy is detailed, comprehensive, and concerned with both practical measures in the near term and the arc of progress over the long term. And embedded within it are three ideas that are likely to have on-going relevance for ammonia energy implementation.

Case Study of Ammonia Production in the Island States Using Ocean Thermal Energy

The world’s oceans are the largest collectors and storage of solar energy and have an enormous potential to supply growing worldwide energy demands, commodity products like ammonia and fresh water. This case study focuses on the island states for implementation of the Ocean Thermal Energy Conversion (OTEC) in the foreseeable future within two decades. Small Island Developing States (SIDS) and other island states exclusively rely on petroleum-liquid based power generation, specifically fuel oil and diesel. For example, power generating capacities of Mauritius, Reunion, St Thomas and St Croix are 480 MW, 435 MW, 200 MW and 120 MW, respectively. Fossil…

Ammonia As Hydrogen Carrier to Unlock the Full Potential of Green Renewables

For decades, grid-scale energy storage has been used to balance load and demand within an energy generation system composed mainly of base load power sources enabling thus to large nuclear or thermal generating plant to operate at peak efficiencies. Energy storage has contributed over the time to meet peak demand and regulate frequency beside peak fossil fuel power plant who usually provided the bulk of the required energy. In the aforementioned context where inherent variability of the power generation asset was mainly a minor issue, energy storage capacity remains nevertheless limited for economic reason storing electricity during low electricity demand…

Ammonia Featured in South Australia’s Hydrogen Action Plan

The Australian state of South Australia took another step into the hydrogen future this week when it unveiled its Hydrogen Action Plan at the International Conference on Hydrogen Safety in Adelaide.  The heart of the Action Plan consists of the practical measures that governments undertake in areas such as infrastructure, workforce, and regulatory framework development.  Zoom out, though, and it is clear that fostering a major export position in green hydrogen is first among equals in the Action Plan's priorities.  And this being the case, it is no surprise that ammonia is singled out for special attention.

Hydrogen Prioritized in New ARENA Investment Plan

On September 11, the Australian Renewable Energy Agency (ARENA) issued its 2019 Investment Plan. The theme of the accompanying press release is “sharpening our focus,” and indeed the agency articulates just three investment priorities: “integrating renewables into the electricity system;” “accelerating the growth of a hydrogen industry;” and “supporting industry to reduce emissions.” The prioritization of hydrogen – and with it, ammonia as a possible hydrogen carrier – is a new development for ARENA.

Engie, Siemens, STFC, and Ecuity awarded funding for green ammonia-to-hydrogen in UK

Last week, the UK Department for Business, Energy and Industrial Strategy (BEIS) announced a "£390 million government investment to reduce emissions from industry," with a focus on low-carbon hydrogen supply and clean steel production. As part of this investment, a consortium led by Ecuity Consulting that includes Siemens, Engie, and the Science & Technology Facilities Council (STFC), has been awarded £249,000 to perform "valuable research on the role of ammonia in the delivery of low cost bulk hydrogen for use in the UK energy system."
