How to build a green shipping corridor

COP27 saw an exciting number of green shipping corridor announcements. But the question remains: how do we actually build them? Earlier this year, the Maersk McKinney Møller Centre for Zero Carbon Shipping launched a Feasibility Phase Blueprint, setting out some key assessment criteria to consider. At the recent annual AEA conference in Phoenix, we took a group of sixty participants through the criteria, asking how and where the ammonia sector should engage.

New report released on environmental hazards of ammonia spills

Ricardo, Lloyd’s Register and the Environmental Defense Fund have used extensive modeling to assess the environmental impacts of large-scale ammonia spills in a variety of maritime scenarios. The study concludes that large-scale spills will have a high impact on certain environmental settings, and in particular fish species. The report also indicates that ammonia is less likely to spread & persist in the environment compared to a spill of conventional maritime fuel, and in some cases will pose less of a threat to certain species. More considerations need to be worked through, including health risks to a ship’s crew.

Safe ammonia bunkering at the Port of Roenne

In our latest episode of Maritime Ammonia Insights, we delved into an exciting new project for maritime ammonia: the Bornholm Bunkering Hub. Maja Bendtsen (Port of Roenne), Jan Gramkov (Rambøll) and Nicklas Koch (DBI) presented the feasibility, safety management & public perception work currently in progress, as well as the steps still required to formalise a plan forward for the hub by 2025. Early & repeated engagement with the local community, rigorous & standardised assessment of potential risks and utilising learnings from other industries were all emphasized by the speakers as key to realising the project.

Key Singaporean safety study releases report

Nanyang Technical University, the Singapore Maritime Institute, ASTI and the American Bureau of Shipping have released their long-awaited report into safety considerations for ammonia bunkering. The report identifies the highest-risk bunkering scenarios, uses theoretical release simulations to determine maximum impact distances, and outlines the key requirements for developing mitigation measures going forward.

Dancing with wind solution for the green hydrogen and green ammonia plant

What renewable energy contradicts the existing traditional ammonia synthesis system the most is fluctuating power output. Envision Group strives to solve this problem. “Dancing With Wind Solution” means with the help of integrated control system and management system, Envision is right now designing dynamic system optimization of the ammonia synthesis process. When the wind speed changes, all the downstream processes and systems will change their power input requirements accordingly.

Ammonia cracker: design and safety considerations

Ammonia cracking is an endothermic reaction with characteristics similar to those of steam methane reforming. As a result, large scale ammonia crackers are likely to more than a passing similarity to the steam-methane reformers which are currently used to convert natural gas to hydrogen. When transferring technology from one industry to another the challenge is to distinguish between know-how which benefits the new application, and which should therefore be applied; and know-how which is detrimental to the new application and therefore needs to be either unlearnt or relearnt. The presentation will cover the choices facing the designer of a large-scale…

Ammonia terminal in port areas: safety and image issues in storage, throughput and transport

Ammonia is an important carrier of hydrogen which is very interesting considering the search for alternative energy sources. The world is looking for ways to reduce our global carbon footprint, and this will give opportunities for ammonia. Preferred location for terminals are port areas, especially in situations where energy is obtained by solar energy and where ammonia is used as a way to transport this energy to less sunny parts where energy is needed. But how about the risks of storage, handling and transportation of ammonia? And what is the public image on the risks of ammonia, and how to…

Ammonia as a marine fuel – bunkering operation and dispersion simulations

Global warming is linked strongly to increased greenhouse gas (GHG) concentration in the earth’s atmosphere. The maritime cluster plays a critical role in reducing GHG emissions by replacing fuels of fossil origin with low-carbon or carbon-free alternatives. As a carbon-free fuel, anhydrous ammonia has received much attention recently due to its established production technology, distribution infrastructure, and satisfactory energy density as a marine fuel. Unlike normal ambient liquid fuels, ammonia relies on refrigeration or pressurization to maintain the liquid phase. Boil-off gas (BOG) can be generated at constant pressure by the addition of heat to saturated liquid and involves significant…

Ammonia Green Corridors – The Opportunity Is Now

Since the Clydebank Declaration was signed last December, the prospect of ammonia-fueled, green maritime corridors has been steadily rising. The Global Maritime Forum has just released a valuable discussion paper on potential definitions and approaches for green corridors. Recent announcements in Europe, Singapore, Australia and the Nordic countries demonstrate growing momentum. For maritime stakeholders to capture early learnings and best manage the complex task of alternative maritime fuel scale-up, the opportune time is right now.

Developing ammonia maritime engines & fuel: a collaborative approach

The latest episode of Maritime Ammonia Insights webinar centred around collaboration, leadership & Singapore: three critical elements in the maritime ammonia transition. Sofia Furstenberg Stott was joined by Peter H. Kirkeby (MAN Energy Solutions) and Yi Han Ng (Maritime and Port Authority Singapore), who discussed timelines for engine development, the benefits of a consortia approach, and the all-important safety & technical progress of maritime ammonia technologies.
