IHI Commits to Ammonia Energy. Big Time.
Article

During his presentation at the November 2017 NH3 Energy + Topical Conference, Shogo Onishi of IHI Corporation described the progress made by IHI and Tohoku University in limiting NOx emissions from ammonia-fired gas turbines (AGTs).  Regular attendees of the annual NH3 Fuel Conference identify IHI with its work on AGTs since the company also addressed this topic at the 2016 and 2015 events.  However, a scan of published materials shows that AGTs are just one aspect of IHI’s activity in the ammonia energy arena.  In fact, IHI is also looking at the near-term commercialization of technologies in ammonia-coal co-firing in steam boilers and direct ammonia fuel cells.  This level and breadth of commitment to ammonia energy is unique among global capital goods producers.

Full program announced for the 2018 NH3 Event Europe
Article

The second annual European Conference on Sustainable Ammonia Solutions has announced its full program, spread over two days, May 17 and 18, 2018, at Rotterdam Zoo in the Netherlands. The international cadre of speakers, representing a dozen countries from across Europe as well as the US, Canada, Israel, and Japan, will describe global developments in ammonia energy from the perspectives of industry, academia, and government agencies.

Process Superstructures and the Production of Cost-Advantaged Ammonia
Article

At the 2017 NH3 Energy+ Conference, graduate student Doga Demirhan reported on an ongoing investigation at the Energy Institute at Texas A&M University. The work involved evaluation of options for an ammonia production system and concluded that biomass could be an economically viable feedstock under current, real-world conditions. This is a notable outcome. Just as notable is how it was reached.

Ammonia from Offshore Wind: a techno-economic review on the US East Coast
Article

A new study examines the technologies needed to produce renewable ammonia from offshore wind in the US, and analyzes the lifetime economics of such an operation. This is the latest in a years-long series of papers by a team of researchers from the University of Massachusetts, Amherst, and Massachusetts Institute of Technology (MIT). And it is by far the closest they have come to establishing sustainable ammonia as being cost-competitive with fossil ammonia.

H2@Scale in California: A Role for Ammonia?
Article

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.

The capital intensity of small-scale ammonia plants
Article

The list of investment drivers for building new ammonia plants in the US over the last few years was short, beginning and ending with cheap natural gas. Markets change, however, and the investment drivers for the next generation of new ammonia plants might include low cost electrolyzers, low cost renewable power, carbon taxes, and global demand for ammonia as a carbon-free energy vector. For this to make sense, however, ammonia needs to be produced without fossil fuel inputs. This is perfectly possible using Haber-Bosch technology with electrolyzers, but today's wind and solar power plants exist on a smaller scale than could support a standard (very big) Haber-Bosch plant. So, to produce renewable ammonia, small-scale ammonia production is essential. This time series chart shows the capital intensity of today’s ammonia plants. Together, the data illustrate competitive advantages of alternative investment strategies, and demonstrate a shift away from the prior trend toward (and received wisdom of) monolithic mega-plants that rely on a natural gas feedstock.

Australian Renewable Energy Agency Issues H2 Fuel Carriers RFP
Article

One of Ammonia Energy’s “top ten” stories of 2017 described Australia’s early steps toward export of renewable hydrogen in the form of green ammonia.  The story said that “Agencies such as the Australian Renewable Energy Agency (ARENA) made it clear during the year that the country intends to build on [its historical] position” as a supplier of fossil energy to countries such as Japan.  ARENA took a tangible step in this direction on December 20, 2017 with the release of a Request for Proposal for a AUD$20 million (USD$16 million) renewable hydrogen R&D funding program.  Included in the scope, per ARENA’s 2017 Investment Plan, could be “demonstration of renewable production methods for transportable energy storage options (such as hydrogen or ammonia).”

Sustainable Energy for Wales: Tidal and Wind with Ammonia Storage
Article

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.

Ammonia Positioned for Key Role in Japan's New Hydrogen Strategy
Article

The Japanese government has 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. The announcement was made on December 26, 2017, by the Agency of Natural Resources and Energy (ANRE), the lead agency on energy policy within the Ministry of Energy, Trade, and Industry (METI). Perhaps the most important indicator of ammonia’s positioning as the lead energy carrier can be seen in the development timelines that are assigned to each energy carrier. The Strategy calls for “CO2-free ammonia” to come into use “by the mid-2020s.”

Green ammonia demonstration plant in The Netherlands
Article

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.
