International Chamber of Shipping endorses “Reducing CO2 Emissions to Zero,” with ammonia as a maritime fuel

The International Chamber of Shipping has published a short but powerful report to "endorse" the International Maritime Organization's Initial Strategy on Reduction of GHG Emissions from Ships, adopted in April 2018. The ICS report calls the IMO's Initial GHG Strategy "a historic agreement which the global industry, as represented by ICS, fully supports," and discusses four fuel technologies that could deliver the IMO's targets: batteries, hydrogen, ammonia, and nuclear.

The ICS report also demonstrates four realities, which apply, perhaps uniquely, to the maritime sector. First, corporations are driving change, in advance of government legislation. Second, these corporations are looking for more than incremental reductions in emissions and instead targeting total sectoral decarbonization with the ambition "to achieve zero CO2 emissions as soon as the development of new fuels and propulsion systems will allow." Third, they realize that LNG and other low-carbon fuels cannot meet these targets: "the ultimate goal of zero emissions can only be delivered with genuine zero CO2 fuels that are both environmentally sustainable and economically viable." Fourth, they recognize that, because ships are long-lived assets, the need to invest in zero CO2 fuel technologies is urgent and immediate.

What drives new investments in low-carbon ammonia production? One million tons per day demand

Last week, the International Maritime Organization (IMO) formally adopted its Initial GHG Strategy. This means that the shipping industry has committed to "reduce the total annual GHG emissions by at least 50% by 2050," and completely "phase them out, as soon as possible in this century."

This also means that a global industry is searching for a very large quantity of carbon-free liquid fuel, with a production and distribution infrastructure that can be scaled up within decades. The most viable option is ammonia. How much would be required? Roughly one million tons of ammonia per day.

P2X, Ammonia Highlighted for Long-Haul Road Transport, Shipping

The International Renewable Energy Agency (IRENA), in partnership with the International Energy Agency (IEA) and Renewable Energy Policy Network for the 21st Century (REN21), released a report this month entitled "Renewable Energy Policies in a Time of Transition." The 112-page document is a comprehensive survey of technologies, policies, and programs that have current or prospective roles in the global transition to a sustainable energy economy. 

For the ammonia energy community, one of its conclusions stands out in vivid relief:

"Developing P2X is crucial because it plays a key role in decarbonising long haul road transport, aviation and shipping sectors that are difficult to decarbonize ... The overall recommendation for developing P2X is to focus on the development of ammonia for the shipping sector as well as long haul road transport, where few or no competing low carbon technologies exist and P2X is expected to be economically viable."

Decarbonising Maritime Transport: OECD report sees ammonia fuel enabling carbon-free shipping by 2035

Twelve months ago, I wrote here that "the shipping industry is beginning to evaluate ammonia as a potential 'bunker fuel,' a carbon-free alternative to the heavy fuel oil (HFO) used in maritime transport." Around that time, I described the obstacle to adoption of ammonia fuel as an information gap, rather than a technology gap, because no new technology was required: the industry simply did not know about ammonia. This information gap had allowed the industry to believe that "CO2 reduction objectives will only be achievable with alternative marine fuels which do not yet exist." I'm glad to announce that this information gap is closing, and fast.

According to a report published last week by the International Transport Forum, the OECD's "think tank for transport policy," the use of "currently known technologies could make it possible to almost completely decarbonise maritime shipping by 2035." This conclusion requires the adoption of ammonia as a zero-carbon fuel.

Pilot project: an ammonia tanker fueled by its own cargo

Last month, an important new consortium in the Netherlands announced its intention to research and demonstrate "the technical feasibility and cost effectiveness of an ammonia tanker fuelled by its own cargo." This two-year project will begin with theoretical and laboratory studies, and it will conclude with a pilot-scale demonstration of zero-emission marine propulsion using ammonia fuel in either an internal combustion engine or a fuel cell.

Bunker Ammonia: new report quantifies ammonia as “the most competitive” fuel for zero-emission maritime vessels in 2030

This week, Lloyd's Register published the most significant comparative assessment so far of ammonia's potential as a zero-emission maritime fuel.

The new report compares ammonia, used in either internal combustion engines (ICE) or fuel cells, to other low-carbon technologies, including hydrogen, batteries, and biofuels, estimating costs for 2030. It concludes that, of all the sustainable, available options, ammonia "appears the most competitive."

The Maritime Industry Begins Assessment of Ammonia as a Fuel

In the last 12 months ...
The maritime industry has begun assessing ammonia as a carbon-free fuel, for internal combustion engines and fuel cells. This marks the first time since the 1960s, when NASA used ammonia to fuel the X-15 rocket plane, that industry players have seriously considered ammonia for transport applications.

Bunker Ammonia: momentum toward a “sus­tainable and future-proof” maritime fuel

The maritime industry is beginning to show significant interest in using ammonia as a "bunker fuel," a sustainable alternative to the highly polluting heavy fuel oil (HFO) currently used in ships across the world.

In recent months, a firm of naval architects and a new maritime think tank have both been evaluating ammonia as a fuel. This includes a road map for future research, and collaborations for a demonstration project that will allow them to design and build a freight ship "Powered by NH3."

Bunker Ammonia: carbon-free liquid fuel for ships

The shipping industry is beginning to evaluate ammonia as a potential "bunker fuel," a carbon-free alternative to the heavy fuel oil (HFO) used in maritime transport.

International trade associations are leading the effort to decarbonize the sector, in alignment with targets set by the Paris Climate Agreement. Their immediate challenge is simple to state but hard to solve: "ambitious CO2 reduction objectives will only be achievable with alternative marine fuels which do not yet exist." In the long-term, however researchers recognize that "fuel cell-powered ships are likely to dominate, drawing their energy from fuels such as hydrogen and ammonia."
