Rio Tinto and AngloEastern have announced they will develop Newcastlemax class, ammonia-powered bulk carriers. The dry cargo vessels will be the maximum size allowed to dock in the Port of Newcastle, Australia: an important coal & iron ore port in global maritime trade. Both AngloEastern and Rio Tinto are members of an Itochu-led maritime fuel study investigating the use of ammonia. In Japan, a "greener ships" consortium has produced its first-ever ammonia-powered design: a Panamax-class bulk carrier. And the China State Shipbuilding Corporation will develop two 93,000 m3 ammonia-powered ammonia carrier vessels, with Bureau Veritas granting AiP for the vessel design.

3rd generation ammonia synthesis: new catalysts & production pathways
We look at four new developments this week:
1. A team from DTU Energy and the Dalian Institute of Chemical Physics have uncovered a new class of alternative catalysts for mild condition ammonia synthesis. The ternary ruthenium complex hydrides Li4RuH6 and Ba2RuH6 avoid the energy-intensive pathway of nitrogen dissociation in a "synergistic" manner.
2. A team from the Korea Institute of Machinery and Materials reported a highly selective (95%) plasma ammonia synthesis method.
3. A team from Delft University of Technology has presented an present an "unconventional electrochemical design" that physically separates hydrogen and dinitrogen activation sites.
4. A team at the Max Planck Institute for Coal Research has demonstrated a new mechanochemical ammonia synthesis system that operates at room temperature and pressures as low as 1 bar.
The Ammonia Academic Wrap: a new breakthrough for eNRR research and more
This week: a new breakthrough for eNRR research, ammonia production from food waste and brown-water, the huge potential of green ammonia production from hybrid solar-wind across the globe, predicted cost dynamics of electrolyser technology, and hydrogen production using selective ion membranes.
The Emerging Ammonia-Methanol Dialectic
Based on recent press reports, ammonia has a new friend: methanol. With the two upstart fuels being mentioned together with increasing frequency, they seem poised to develop on parallel paths as each seeks market applications where it can become a mainstay solution.
