In April 2016, the United States Department of Energy (DOE) released a Funding Opportunity Announcement (FOA) for its Renewable Energy to Fuels through Utilization of Energy-dense Liquids (REFUEL) program. The focus of the program is carbon-neutral liquid fuels (CNLFs). In the DOE’s formulation, CNLFs are to be produced “from air and water using electrical or thermal energy from renewable sources.”
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."
On September 1st, academic journal Energy & Fuels published a new paper that features research coming out of the UK's Cardiff University and Ireland's University of Limerick. This study demonstrates a "reduced mechanism" for simulating the "robust numerical analyses with detailed chemistry" necessary for the "industrial implementation" of ammonia in gas turbine combustion for "future power generation." Here's the abstract:
South Korean researchers have successfully road-tested a dual fuel passenger car that runs on a mixture of ammonia and gasoline. It is called the AmVeh and was developed by members of the Ammonia Research Group at the Korean Institute for Energy Research. The prototype vehicle uses a fuel ratio of 70% ammonia to 30% gasoline to power a spark ignition engine. As ammonia contains no carbon, this fuel ratio results in a corresponding 70% reduction in carbon dioxide emissions, compared to pure gasoline. The AmVeh team is now focused on improving the fuel system and the exhaust after-treatment system. Once these are optimized, they aim to develop an engine system that runs on ammonia alone, without any support from gasoline.
A new sports car that uses ammonia fuel is touring the motor shows of Europe. The Marangoni Toyota GT-86 Eco-Explorer is an ammonia / gasoline hybrid, designed by Italian tyre-maker Marangoni, which claims 111 miles of zero-emission driving from one tank of ammonia. This month the car is completing a press tour of the UK.
Following last year’s field trials of Diverse Energy’s PowerCube technology in Africa (and AFC Energy’s subsequent acquisition of assets from Diverse), an EU-funded project to commercialize ammonia-fed fuel cells for stationary power generation continues to gather momentum under the title “Project Alkammonia".
