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.

Ammonia technology portfolio: optimize for energy efficiency and carbon efficiency

Earlier this month, I had the pleasure of speaking at the International Fertilizer Association's (IFA) conference on the subject of Innovations in Ammonia. A key point was the benefit of technology diversification: as with any portfolio, whether an investment account or a global industry's range of available technologies, concentration in any area represents risk, and diversification represents resiliency. Unfortunately, the ammonia industry has grown highly concentrated, and its dependency upon one technology and one feedstock represents significant risk in tomorrow's markets.

This article features five charts that aim to demonstrate why energy efficiency is insufficient as the only measure of technology improvement, why it is better to optimize instead of maximize, and why market evolution is necessary to support investment decisions in sustainable ammonia synthesis technologies.

On the Ground in Japan: Hydrogen Activity Accelerates

A recent Ammonia Energy post mentioned that in December 2017 “the Japanese government . . . approved an updated hydrogen strategy which appears to give ammonia the inside track in the race against liquid hydrogen (LH2) and liquid organic hydride (LOH) energy carrier systems.”  While this news is positive, the hydrogen strategy remains the essential context for economic implementation of ammonia energy technologies in Japan; ammonia’s prospects are only as bright as those of hydrogen.  This is why Ammonia Energy asks from time to time, how is hydrogen faring in Japan?

Ammonia Flash Cracking and Energy Development in Southern Africa

New ammonia production capacity is being built in southern Africa. The outputs will support agricultural development in the region – but could also support development of ammonia as a universal energy commodity. A British start-up company is currently at work to develop a beachhead use case for ammonia energy.

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.

H2@Scale in California: A Role for Ammonia?

The U.S. Department of Energy H2@Scale program’s November 2017 workshop in California included mention of ammonia as a constituent of a future hydrogen economy. It also highlighted the relevance ammonia energy could have in California.

California stands out globally as a large economy that is strongly committed to development of a hydrogen economy. The state’s strategy for hydrogen-powered transportation involves reducing the production cost of renewable hydrogen and the capital and operating costs of hydrogen fueling stations. It does not explicitly address the cost of intermediate hydrogen logistics.

The question of cost is of utmost importance because California has so far put $120 million of public funds into hydrogen fueling stations and intends to invest an additional $20 million per year through 2022. The state’s aspiration is to move to a point where hydrogen that is used as a motor fuel is free of public subsidy. So it clearly behooves the state to investigate how ammonia could be used as a cost-reducing energy carrier.

Toyota is active in California’s hydrogen movement and has announced plans to build a renewable hydrogen plant that will use cow manure as a feedstock. A project with a different conception, one that draws upon the solar and wind resources of the Mojave Desert to produce renewable hydrogen and logistically advantaged ammonia, would align better with the state’s sustainability objectives.

Sustainable Energy for Wales: Tidal and Wind with Ammonia Storage

As part of the sustainable agenda of the UK, the government, research institutions and various enterprises have looked for options to reduce the carbon footprint of the country while ensuring energy independence for several years. As a response, one of the alternatives has been to introduce the use of marine energy via the implementation of a barrage in the Severn Estuary or the development and implementation of Tidal Lagoons located around the Welsh coast. From these alternatives, the tidal lagoon concept seems to be most feasible.

Hybrid tidal and wind energy systems will produce vast amounts of energy during off-peak hours that will require the use of energy storage technologies - the size of each proposed tidal lagoon ranges close to ~1.5 GW. Currently, companies involved in the development of these complexes are thinking of batteries, pumped hydro, and ammonia as the potential candidates to provide storage for these vast amounts of energy.

Green ammonia demonstration plant in The Netherlands

Last month, a heavyweight consortium of local and global companies announced plans to collaborate on a project to design, build, operate, and evaluate a demonstration plant to produce "green ammonia" from water, air, and renewable energy in The Netherlands.

This is one practical outcome of last year's Power-to-Ammonia study, which examined the economic and technical feasibility of using tidal power off the island of Goeree-Overflakkee in Zuid-Holland to power a 25 MWe electrolyzer unit, and feed renewable hydrogen to a 20,000 ton per year green ammonia plant.

This new demonstration plant phase of the project will still be led by the original developer, Dutch mini-ammonia plant developer Proton Ventures. However, its partners in the venture now include Yara and Siemens, as well as speciality fertilizer producer Van Iperen, and local sustainable agricultural producer, the Van Peperstraten Groep.
