Comparative studies of ammonia production, combining renewable hydrogen with Haber-Bosch

In recent months, research teams from both Canada and Italy have published comparative analyses of sustainable ammonia production pathways. These projects aim to quantify the costs and benefits of combining Haber-Bosch with a renewable hydrogen feedstock. Both projects examine the carbon intensity of ammonia production but, while the Canadian study broadens its remit to a full life cycle analysis, including global warming potential, human toxicity, and abiotic depletion, the Italian study focuses primarily on energy efficiency.

University of Minnesota’s Ammonia Program

The American Institute of Chemical Engineers (AIChE) will present a Webinar on December 21 on "Distributed Ammonia Synthesis." The presenter will be Edward L. Cussler, Distinguished Institute Professor at the Chemical Engineering and Materials Science Department of the University of Minnesota. Distributed ammonia synthesis is one focus related to ammonia energy at the University of Minnesota - but just one. In fact, UMinn is the locus of a unique and globally significant collection of research efforts that promise to have significant impacts in the ammonia industry and the broader energy sector.

Nuon’s Power-to-Ammonia update, and the first European ammonia fuel conference in 2017

An article in the latest issue of Dutch-language magazine NPT Proces Technologie provides a detailed update on the Nuon project, about which we wrote a few months ago. Nuon's Power-to-Ammonia project looks at grid-scale storage of "seasonal surplus" electricity from wind and solar in the form of ammonia. Proton Ventures, the originators of the Power-to-Ammonia concept in The Netherlands, have also been sharing details of the project in recent conference presentations - and announced that they will be hosting the first European ammonia fuel conference, in Rotterdam, in May 2017.

NH3 Fuel Association President Presents at AIChE Annual Meeting

NH3 Fuel Association President Norm Olson presented his paper “NH3 – the Optimal Liquid Transportation Fuel” on November 9 at the annual meeting of the American Institute of Chemical Engineers (AIChE). The AIChE meeting, held over six days in San Francisco, provided a wide-ranging perspective on the sustainable energy landscape that ammonia energy must compete within.

Ammonia for Green Energy Storage and Beyond

Siemens is participating in an all electric ammonia synthesis and energy storage system demonstration programme at Rutherford Appleton Laboratory, near Oxford. The demonstrator, which will run until December 2017, is supported by Innovate UK. Collaborators include the University of Oxford, Cardiff University and the Science & Technology Facilities Council.

Small Scale Low-Pressure Ammonia Synthesis

Ammonia is one of the most important chemical commodities in the US and will be a key component in helping the world meet the rising demand for food and energy. Ammonia is needed in distributed locations for agriculture (as fertilizer for small grain and corn production), for indirect hydrogen storage1 (transported as a liquid at moderate pressure to hydrogen stations), or as a liquid fuel2 (for internal combustion engines or solid oxide fuel cells). Recently, there has been significant effort to develop scalable technologies for conversion of intermittent energies (e.g., solar, wind) into energy dense carbon-neutral liquid fuels, and ammonia…

Siemens – Green Ammonia

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.

Nuon – Power to Ammonia

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.

Displacing Diesel Fuel with Carbon-Free Anhydrous Ammonia

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."
