Hyundai joins Fortescue and CSIRO to "fast track" ammonia to high-purity hydrogen system

Trevor Brown September 03, 2020

Fortescue recently announced that it has signed a memorandum of understanding (MOU) with Hyundai Motor Company and CSIRO for the “development and future commercialisation” of its metal membrane technology. This technology, which produces high-purity compressed hydrogen from liquid ammonia, was demonstrated in 2018. It enables PEM fuel cell vehicles to refuel using hydrogen that is generated on demand from ammonia. At scale, this technology could enable an ammonia-based hydrogen production, storage, and distribution infrastructure, lowering the barriers to implementation of a national network of hydrogen filling stations. Now, “Hyundai will seek to demonstrate the viability of the technology for renewable hydrogen production and vehicle fuelling in Korea.”

Zero emission aircraft: ammonia for aviation

Trevor Brown August 20, 2020

This week, Reaction Engines announced a “ground-breaking study” on ammonia as a fuel for zero-emission aircraft. This will soon be followed by a demonstration project, “integrating the technology into a ground-based test engine.” The study combines Reaction Engines’ heat exchanger technology with the ammonia cracking technology being developed by the UK’s Science and Technology Facilities Council (STFC). By partially cracking green ammonia to hydrogen, the resulting ammonia fuel mix “mimics jet fuel,” making it possible to adapt existing engines and aircraft to use zero-emission fuels. “This means a fast transition to a sustainable aviation future is possible at low cost.”

Hazard identification, feedback loops, risk tolerance

Trevor Brown August 13, 2020

There are many lessons to be drawn from the explosion in Beirut last week. Perhaps the most important is that we, as a society, always have a choice: to learn from our mistakes, or to repeat them. We can debate the root cause and find individuals and systems at fault — and we must do these things — but if we don’t make use of those learnings, and change our future behavior, we’ll have missed the point. As one commentator put it, the cause of the Beirut explosion was clear-cut: “Once again, society not learning from its own mistakes. For hundreds of years, there have been situations where too much ammonium nitrate has been kept in the same place at the same time.”

Green ammonia at oil and gas scale: the 15 GW Asian Renewable Energy Hub

Trevor Brown August 06, 2020

The Asian Renewable Energy Hub will be a 6,500 square kilometer wind and solar farm in Australia's Pilbara desert, producing green ammonia for export beginning in 2027/28. This was recently reported as an investment of AU$ 22 billion (US$ 16 billion). As it says on its website, this is "renewable energy at oil and gas scale." Details recently entered the public domain regarding the project's upstream segment (power generation). Now, its downstream segment (green ammonia production) is coming into focus as well. InterContinental Energy, one of the project backers, represents the Asian Renewable Energy Hub as just one project within its $100+ billion, 50 million ton per year, green ammonia and green methanol production portfolio: "the largest and most advanced portfolio of green hydrogen projects worldwide."

Solar ammonia, available in Spain from 2021

Trevor Brown July 30, 2020

Last week, Iberdrola and Fertiberia announced plans to start producing green ammonia for “fertilizantes libres de emisiones” (emission-free fertilizers). Iberdrola will invest EUR 150 million to build the 100 MW “Puertollano II” solar field, with a 20 MW electrolyzer bank to produce renewable hydrogen. Fertiberia will “update and modify” its existing Puertollano plant to consume this green hydrogen, reducing its natural gas use by “over 10%,” and producing green ammonia beginning in 2021.
