Ammonia-powered West Australia to East Asia green corridor in five years

The West Australia – East Asia Iron Ore Green Corridor Consortium has released a study showing the way for a green corridor to use ammonia fuel. The study looked closely at the capability of the ports to provide ammonia bunkering and sources of clean ammonia.

Ammonia-powered ships could be a reality quickly, because the engine architecture is very similar to current marine engines. However, storage of ammonia bunkers at sea is still an issue, and safety standards have not yet been designed.

The consortium started in November of 2021, with major charterers BHP and Rio Tinto, and shipping companies Oldendorff Carriers and Star Bulk Carriers working jointly to make the corridor successful.

I was unsuccessful in finding a copy of the actual report online. but it’s good news, because this route is one of the major world bulk carriage routes, and reductions in emissions will be helpful.

UMAS report details green priorities for shipping

UMAS is an acronym for University Maritime Advisory Service, a commercial advisory service, or consulting firm, focusing on the maritime segment. It makes use of the University College London shipping team as subject matter experts, and takes on relevant projects for the maritime industry.

Recently they’ve released a report entitled A Strategy for the Transition to Zero-Emission Shipping, which tries to spell out ways that a pathway to a 1.5 degree Centigrade increase could be found. It’s an interesting study because it deals with not only the science-based facts about fuels and propulsion systems, and ship designs, but also with the organizational, regulatory, private investment, and geopolitical aspects of a transformation.

The study outlines three scenarios for a fuel transition away from fossil fuels. These are:

  • A spread from a strong first-mover country to others
  • Independent spread from several countries
  • Global actions (such as the IMO) to drive international spread.

The report goes on to identify levers for change in each scenario, covering three phases of the transition to 1.5 degrees C. The phases are Emergence, Diffusion, and Reconfiguration. They are captured in Figure 19, on page 67 of the report. Here you can see the importance of developing new technologies and investing to expand deployment in the first two phases.

The question they address is how to get all the factors necessary to work for the change in each phase. Especially important are the Energence and Diffusion phases, partly because that’s where we are now, and partly because success there largely determines how we reach the final phase.

The report sees a place for all three scenarios in the effort. It’s quite clear about how companies, governments of states, and international organizations could participate and make the transition easier.

One interesting point is the attention paid to constructing green corridors between different ports, both domestic routes and international ones. The green corridor movement is a powerful driver, and there are now lots of examples starting to appear; they are outlined in the report. The analysis is quite detailed, with actual corridor possibilities outlined, and key national players identified. Experience with the difficulties of establishing them will be important to make the process easier in the future.

The report is also positive about the IMO and its role, while acknowledging some of the difficulties relying on it introduces.

It’s quite an exceptional work, and I recommend reading it. I wish I’d been part of it!

ABS simulating green maritime corridors

American Bureau of Shipping (ABS), a US-based classification society, has announced that it is developing simulations of potential green maritime shipping corridors. Such a tool will allow users to determine if a particular corridor is feasible, and what the costs will be.

Simulations will also allow us to determine the range of improvements that will be required, and the sensitivity of costs to many different choices, like size of bunkering facilities for different alternative fuels. These sorts of metrics are very important when deciding how much to invest in a green corridor development.

The article below doesn’t reveal very much. But it’s clear that a major classification society can play a major role to influence the greening of maritime routes.
