Meet Yara and Fertilizers Europe, two organisations currently exploring the potential for renewable fertilizer in Europe.
Join BLG and the Green Hydrogen Organisation to explore equitable development & climate justice considerations for ammonia project developers, with examples from Canada and global certification development.
US-based Mainspring Energy has announced successful testing of pure ammonia fuel in its Linear Generator technology. Running on pure (anhydrous) ammonia, the overall system efficiency was 1% higher than conventional gas fuels, and Mainspring indicates that “off-the-shelf” technology available for current gas turbine models can yield NOx emissions that “meet any permitting standard”. Mainspring aims for its product to displace diesel-powered backup generators in a variety of applications.
As part of a new round of funding announcements, the US Department of Energy will contribute nearly $10 million to three significant ammonia energy initiatives:
In order to demonstrated ammonia-fueled solutions in a variety of applications, Stuttgart-based organisation Ammonigy has developed two patented technologies: a modular cracking unit that provides hydrogen to act as an “igniter” for the ammonia fuel, and an exhaust treatment system to minimise NOx emissions from the engine. But, while the principles behind Ammonigy’s technology solutions are very familiar to our readers, using them to convert a speedboat to run on ammonia fuel is certainly new! This week we explore results from testing on the GREEN AMY: the world’s first ammonia-powered speedboat.
The South China Morning Post reports that China Energy Investment Corporation has successfully demonstrated co-firing 35% ammonia with coal at a power generation unit in Shandong Province. Further technical details emerged from additional Chinese media outlets, including that the pilot test occurred in a 40 MW coal boiler at the Huaneng Yantai coal power plant, and that NOx emissions were reportedly lower than burning pure coal fuel.
This week we explore four updates in ammonia combustion R&D:
1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.
2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.
3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.
4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.
The journey from the laboratory bench to the shop floor continues apace in 2021, as researchers deepen their understanding of ammonia combustion within engines. The team at Université d’Orléans has published several pieces of research already this year, with interesting results on operating limits, spray characteristics and flame propagation.
