Real Zero, Not Just for Australia
The December issue of Maritime Reporter magazine includes a feature story on Australian mining company Fortescue’s pioneering ammonia fuel trial on the platform supply vessel Green Pioneer.The Green Pioneer was named one of TIME’s Best Inventions of 2025.The conversion journey of its diesel-electric power system to dual-fuel ammonia started in 2022, on land, when Fortescue converted a four-stroke Cummins…

Is There a Viable LNG to Ammonia Fuel Pathway?
Is LNG to ammonia a viable pathway for helping shipowners get to net zero?From an engine point of view there is a pathway, but there are two points to consider, says Lars Tingbjerg Danielsen, Two-Stroke Promotion Manager – Newbuildings at Everllence. First, the case where an engine is capable of burning both methane and ammonia; second the case where an engine starts its service burning methane and…

Rejected Livestock
The recent rejection of around 2,900 dairy cattle on the Spiridon II raises animal welfare and pollution concerns when, after a long sea voyage, the laden vessel has again had to return to sea.The 52-year-old livestock carrier has left Turkey after its cargo was rejected by local authorities. Court transcripts translated by Animal Welfare Foundation indicate that 58 cows died in transit to Turkey, 140 cows had miscarriages in transit…

LNG: Greenwashing or Realism
The October delay at IMO of its Net Zero Framework continues to spark debate, and enthusiasm, about net zero fuel choices, including what LNG’s role should be.Debate is expected to continue too, as shipowners face a more complicated regulatory landscape now. Despite the uncertainty created by the delay, regulations continue to force emissions reductions, including existing IMO regulations such as CII…

In the Search for Ship Energy Efficiency, Don't Forget Waste Heat
Fuel-agnostic and suitable for newbuilds and retrofit, Organic Rankine Cycle waste heat recovery systems are making headway as an energy-efficiency measure.Market prospects are looking so good for waste heat recovery systems that Orcan Energy recently expanded its industry relationships by partnering with Goltens on installations.Andreas Sichert, CEO of Orcan Energy, said: “Waste heat recovery is one of the most powerful and underutilized tools for improving energy efficiency.

Money Pours in for Hull Cleaning Technology
In April this year, the IMO Marine Environment Protection Committee approved guidance on in-water cleaning of ships' biofouling and also approved a proposal for the development of a legally binding framework for the management of biofouling.The move comes in recognition that biofouling is a key contributor invasive species and to greenhouse gas emissions. Biofouling can increase fuel consumption by up to 30%…

The Great Lakes BWMS Regulation Scrum
There hasn’t been an invasives species introduced to the Great Lakes from ballast water since 2006. So, what’s the problem now?As far as Transport Canada is concerned: “Scientific sampling to date consistently shows that ballast water management systems (BWMS) used in the Great Lakes reduce organism densities in ballast water discharges by over 99%, consistent with global evidence. As crews gain experience in operating these systems…

Safeguarding Security on Nuclear-Powered Ships
No civilian maritime nuclear facilities have been commissioned in over four decades, but there’s been three major reports released this month on their future potential.DNV’s latest report, Maritime nuclear propulsion: Technologies, commercial viability, and regulatory challenges for nuclear-powered vessels, provides a regulatory perspective on security, one of the key challenges for future adoption. As it says: Safety, security and non-proliferation remain paramount.

Innovators Tackle Cruise Hotel Loads With and Without Fuel Cells
The Cruise Lines International Association (CLIA) reported in September that the number of member cruise line ships with the ability to use shore power has nearly doubled since 2018.Today, 166 ships are able to plug in at port, a 12% increase from the prior year. These ships represent 58% of the fleet and 65% of capacity.By 2036, 273 ships that can connect are expected to be in service.As part of the EU’s Fit for 55 decarbonization regulations…

Energy Storage and New Fuels Work Together as One on Vessels
There’s an obvious fuel saving advantage, but partnering energy storage systems with new fuels brings other advantages too.There’s a new generation of vessels emerging which is exemplified by Grimaldi’s PCTC Grande Shanghai, claimed to reduce fuel consumption by 50% compared to previous-generation car carriers, and the NCL Vestland, a container feeder vessel similarly claimed to reduce energy consumption…

A Step Forward for Direct Air Capture
Like new fuels and onboard carbon capture, direct air capture (DAC) needs to be scaled up to become an effective decarbonization pathway.This week, German shipowner NSB Group demonstrated its willingness to step forward by entering into a partnership with Phlair, a German direct air capture company.The CO2 removal credits will be produced by capturing CO2 from the atmosphere at Phlair’s direct air capture facility “Dawn” and permanently storing it underground.

Mega Hydrogen Projects Could Make or Break the New Fuel Agenda
This week, RWE withdrew from a $10 billion Namibia green hydrogen project, the latest example of companies considering such investments.The German power utility said on Monday that it had withdrawn from Namibia's Hyphen green ammonia project because demand for hydrogen and hydrogen derivatives such as ammonia is developing slower than expected in Europe.The lack of new fuel availability for shipping…

Bent But Not Broken: Lighter Icebreakers
After developing the technique some five years ago, Aker Arctic has now completed the research required to get its new design methodology for icebreaker hulls accepted into the Finish-Swedish Ice Class Rules. The method has also been adopted to Polar Class rules of several Class Societies (LR, ABS, DNV).Although the research focused on vessels typically sailing the Baltic Sea, Aker Arctic has also used the methodology in many of its recent newbuilding designs including…

Batteries: Looking Beyond Spinning Reserve
Mia Elg, R&D Manager at Deltamarin, says there’s not many of the company’s new designs, no matter what the vessel type is, that don’t include batteries.Installing smaller battery capacity to a diesel engine driven vessel with electrical power train can enable spinning reserve. Here, an optimal number of engines can be kept online, and the batteries can work as a black out preventer. This can save, depending on the type of the ship and operation…
