Green Financing Sighted in Australia's Ammonia Industry
Article

Last month the Commonwealth Bank of Australia (CBA) announced that it has “signed an AUD $400 million [USD $256 million] three-year bilateral sustainability-linked loan” with Australian conglomerate Wesfarmers. This represents at least the second occasion on which an ammonia producer has linked its cost of capital to progress in meeting sustainability goals. In July 2019, Yara announced that it had signed a USD $1.1 billion revolving credit facility with a group of 13 lenders whose margin “will be adjusted based on Yara’s progress to meet its carbon intensity target by 2025.”

Ammonia Included in Japan's International Resource Strategy
Article

Japan’s Ministry of Economy, Trade and Industry has singled out ammonia for the role it can play in the country’s creation of a "carbon-free society." The news was embedded in METI’s New International Resource Strategy which was released on March 30. In the report's framing, ammonia is cited for its association with “the concept of importing renewable energy produced in other countries.” In a departure from the practice found in most reports on the energy transition, the ammonia discussion stands alone and not as one item on a roster of potential renewable energy vectors.

Wärtsilä Tests Internal Combustion of Ammonia
Article

Last week Wärtsilä, the Finnish engine and energy equipment manufacturer, unveiled the latest stage in its engagement with ammonia as an energy vector. In a press release headlined “Wärtsilä advances future fuel capabilities with first ammonia tests,” the company described a test program aimed at exploring ammonia’s properties as an internal combustion fuel. Kaj Portin, General Manager of Fuel & Operational Flexibility in Wärtsilä’s Marine division, commented that “the first tests have yielded promising results.”

South Australia Planning Hydrogen Export Strategy
Article

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.”

Literature Review: Ammonia as a Fuel for Compression Ignition Engines
Article

The diesel engine, also known as the compression ignition (CI) engine, has been a workhorse of the modern energy economy for more than a hundred years. Its role in the coming sustainable energy economy will be determined by its ability to co-evolve with climate-friendly fuels. Two researchers from the National Institute of Advanced Industrial Science and Technology in Japan have now examined the fit between ammonia and the CI engine. Pavlos Dimitriou and Rahat Javaid arrive at a two-part conclusion in their paper, “A review of ammonia as a compression ignition engine fuel,” published in January in the International Journal of Hydrogen Energy. Part one is good news: “Ammonia as a compression ignition fuel can be currently seen as a feasible solution.” Part two is a dose of qualifying reality: to manage emissions of N2O, NOx, and unburnt NH3, “aftertreatment systems are mandatory for the adaptation of this technology,” which means that ammonia-fueled CI engines are likely to be feasible “only for marine, power generation and possibly heavy-duty applications where no significant space constraints exist.”

Japan Advances SOFCs for the Built Environment
Article

A steady stream of Japanese news reports over the last several months attest to the country’s progress in deploying fuel cells in the built environment. Dubbed “Ene-Farms,” the appliances function as micro-scale combined heat and power units, providing electricity as well as heat for domestic applications. Most of the Ene-Farms deployed so far feature proton-exchange membrane (PEM) technology (which requires high-purity hydrogen). However, two recent developments show that solid oxide fuel cell (SOFC) technology (well suited for ammonia) could play a role, maybe even a large role, in Japan's Hydrogen Society.

ARPA-E Issues RFI for Next-Gen Ammonia System Integration
Article

This week the United States Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) issued a Request for Information under the title “Next Generation Ammonia System Integration Project.” This is a strong signal that ARPA-E intends to see the ammonia energy technologies in its portfolio through to commercial fruition.

Gigastack Phase 2 Receives Funding in the UK
Article

Earlier this week the United Kingdom’s Department for Business, Energy & Industrial Strategy (BEIS) announced that a group led by ITM Power has been awarded GBP 7.5 million (USD $9.7 million) for the second phase of a renewable hydrogen project dubbed “Gigastack.” According to the BEIS announcement, “Gigastack will demonstrate the delivery of bulk, low-cost and zero-carbon hydrogen through ITM Power’s gigawatt scale polymer electrolyte membrane (PEM) electrolysers . . .” with the goal of “dramatically reduc[ing] the cost of electrolytic hydrogen.” The hydrogen produced will be used for petroleum refining, although the project partners have their eyes on opportunities that go well beyond desulfurization of oil.

USDoE Issues H2@Scale Funding Opportunity Announcement
Article

Last month the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) issued a USD$64 million funding opportunity announcement (FOA) on behalf of the H2@Scale program. H2@Scale was launched in 2016 by representatives of several U.S. national laboratories with the goal of moving hydrogen energy technologies toward practical implementation. It is certainly one of the United States’ main vehicles for advancing the hydrogen economy. Given this, the program’s investments will do much to determine whether the U.S. is a leader or follower in ammonia energy. In June 2017, Ammonia Energy reported that “ammonia energy had started to move from the extreme periphery of the H2@Scale conceptual map toward its more trafficked precincts.” The EERE FOA shows that while progress is being made, the journey is not yet complete.
