An interesting article this week went behind the scenes at CSIRO to show how the Australian R&D lab is developing energy management systems to link renewable generation with storage technologies - including ammonia, as a chemical energy storage medium, for export to Asia.
I wrote last week about ARPA-E's "transformative" ammonia synthesis technologies, describing three technology pathways under development: low pressure Haber-Bosch, electrochemical processes, and advanced electrolysis. ARPA-E's ambitious R&D program might imply that a meaningful, commercial market for sustainable ammonia is still decades away. It represents, however, only the slow American tip of a fast-moving global iceberg. In Japan, where there's no debate about climate science, the national effort is already well underway, with three programs to develop low-carbon ammonia synthesis under the Cross-ministerial Strategic Innovation Promotion Program (SIP), 'Energy Carriers.'
The US Department of Energy's Advanced Research Project Agency (ARPA-E) is funding projects with a view to commercializing low- and zero-carbon ammonia synthesis technologies. Grigorii Soloveichik, ARPA-E Program Director, described the aims and challenges of his agency's initiative and introduced the technologies currently in development in his keynote presentation at the recent NH3 Fuel Conference, in September 2016.
Solar ammonia' could be the key to the sustainable energy economies of two nations. During his talk at the 2016 NH3 Fuel Conference, Keith Lovegrove, Head of Solar Thermal at IT Power Group in Australia, said that Japan and Australia have the opportunity to move their trade in energy onto a climate-friendly foundation. This would involve development of Australia's solar resources in a way that helps Japan ramp up its Strategy for Hydrogen & Fuel Cells in the coming decades.
The ammonia energy community has an opportunity to provide input to the United States Department of Energy (USDOE) as it defines priority areas for its new "H2 @ Scale" initiative. The USDOE posted a Request for Information (RFI) on September 9. Interested parties are invited to comment on all aspects of the H2 @ Scale concept. The deadline for comments is November 4. A link to the RFI is provided below.
In March 2016 the Dutch utility Nuon announced that it will study the possibility of storing "seasonal surplus" electricity from wind and solar in the form of ammonia. The study by Nuon and Delft University of Technology (TU Delft) is part of the project "Power to Ammonia." The study will be conducted at Nuon's Magnum power station.
In April 2016, Siemens AG announced that it will construct a plant at the Rutherford Appleton Laboratory in Oxford to demonstrate the production of ammonia in an electrochemical reactor. The technology is seen as a facilitator of the use of ammonia synthesis as a method for storing renewably generated electricity. It involves lower pressures and temperatures than conventional synthesis with the Haber Bosch process. The project will test two different electrolyte chemistries using its 30 kilowatt electrochemical reactor.
The team at the University of Minnesota announced last month the award of funding for a demonstration project entitled "Clean Vehicles Fueled by Hydrogen from Renewable Ammonia." This project builds on years of research and investment in renewable ammonia at University of Minnesota, most visibly the prototype wind-to-ammonia production plant operating since 2014 at West Central Research and Outreach Center. Their focus now, however, is shifting to the use of ammonia as a fuel. "The overall objective of the project is to displace up to 50% of the diesel fuel used in tractors with anhydrous ammonia produced from renewable resources."
