Amogy: ammonia-powered semi-truck

Julian Atchison January 26, 2023

Amogy has announced successful testing of its new ammonia-powered, Class 8 semi-truck in Stony Brook, New York. The 300 kW ammonia-to-power system powered the semi-truck for several hours, with full track testing to occur later this month. Amogy now has its sights set on a 1 MW demonstration in a retrofitted tugboat later this year.

Fortescue & Deutsche Bahn to develop ammonia-powered trains in Germany

Julian Atchison October 10, 2022

Deutsche Bahn and Fortescue Future Industries will collaborate to modify existing locomotive diesel engines to run on hydrogen & ammonia fuel. The pair will utilise Ammonigy’s ammonia cracking technology in their design, with a prototype, bench-top engine currently undergoing testing in Germany. This week FFI also signed an agreement to develop a new energy import terminal in Wilhelmshaven.

Ammonia as a liquid for the future of aviation

Jayanta Kapat Marcel Otto

Zero-emission aviation initiatives have mainly focused on using hydrogen or drop-in biofuels and sustainable aviation fuels (SAF) to replace fossil-based jet fuels to achieve near-term reductions in carbon emissions with minimal impacts on the global aircraft fleet and supporting infrastructure. Despite significant advances in the production of such fuels, scaling up manufacturing capability to be cost-competitive remains a challenge. This paper discusses ammonia as a carrier of green hydrogen for aviation, with near-zero emission. Ammonia is proposed as both a carrier of hydrogen as fuel and to provide cooling for compressor intercooling and cooled cooling air for core efficiency improvement,…

Sunborne Systems: bringing keystone technologies to market for the global zero-carbon energy infrastructure

Bill David

At Sunborne Systems, we are developing zero-carbon ammonia-based solutions for heavy transport and high-energy industrial applications. Our keystone technologies are initially focussed on early opportunities in the maritime industry and have high disruption potential across multiple other hard-to-abate sectors. Sunborne Systems was announced a year ago at COP26 in Glasgow and is a joint venture technology company formed by STFC, Reaction Engines and IP Group building upon the technical strengths of Reaction Engines and STFC in thermal management and catalyst chemistry and their in-common expertise in system design and optimisation.

Amogy: Ammonia-powered tractor

Julian Atchison June 09, 2022

Amogy have successfully demonstrated a new ammonia-powered tractor in Stony Brook, New York. A 100 kW ammonia-to-power system was successfully integrated into a John Deere mid-size standard tractor, which can operate on liquid ammonia fuel for a period of several hours.

AFC Energy: Power Tower & off road racing

Julian Atchison April 04, 2022

Two updates from AFC Energy:

1. The “Power Tower”, a 10kW, ammonia-fueled, off-grid power was launched last month, with Keltbray and Acciona to deploy modular units on construction sites mid-year.

2. The launch of Extreme-H off road racing, with green methanol and ammonia likely to act as hydrogen carriers for the hydrogen-fueled racing championship.

Ammonigy: Speedboats powered by green ammonia

Julian Atchison March 02, 2022

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.

South Africa launches Hydrogen Society Roadmap

Julian Atchison February 19, 2022

Four "catalytic" projects will provide momentum for the new roadmap, driving the rollout of at least 15 GW of electrolysis capacity between them by 2040. Ammonia is a feature of all these kick-off projects, and the government sees ammonia's primary role in the transition as decarbonising energy-intensive industries in South Africa.

NASA, Boeing, UCF to study zero-carbon ammonia jet fuel

Julian Atchison February 02, 2022

A $10 million, five-year NASA University Leadership Initiative grant will allow an academic-industry team to develop new ammonia-fed jet engines. Researchers at the University of Central Florida will lead a team including collaborators from Georgia Tech, Purdue University, GE and Boeing. The proposed design uses liquid ammonia fuel, which is cracked to release hydrogen, which will be burned by the engine. The team is using the Boeing 737-8 aircraft as a baseline for the design.
