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?
This week, the government of South Australia announced a "globally-significant demonstrator project," to be built by the hydrogen infrastructure company Hydrogen Utility (H2U). The renewable hydrogen power plant will cost AUD$117.5 million ($95 million USD), and will be built by ThyssenKrupp Industrial Solutions with construction beginning in 2019.
The plant will comprise a 15 MW electrolyzer system, to produce the hydrogen, and two technologies for converting the hydrogen back into electricity: a 10MW gas turbine and 5MW fuel cell. The plant will also include a small but significant ammonia plant, making it "among the first ever commercial facilities to produce distributed ammonia from intermittent renewable resources."
Japan and Saudi Arabia are together exploring the possibility of extracting hydrogen from Saudi crude oil so that it can be transported to Japan in the form of ammonia.
According to a synopsis of the planned effort, “one option for Japan’s material contribution to reducing greenhouse gas emissions [would be] a supply chain for carbon-free hydrogen and ammonia produced through CCS from Saudi Arabian fossil fuels.” The synopsis emerged from a September 2017 workshop sponsored by Saudi Aramco and the Institute of Energy Economics, Japan (IEEJ).
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.
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).”
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.”
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.
This series of articles on the future of ammonia synthesis began with a report on the NH3 Energy+ conference presentation by Grigorii Soloveichik, Program Director at the US Department of Energy's ARPA-E, who categorized the technologies as being either improvements on Haber-Bosch or electrochemical (with exceptions).
ARPA-E invests in "transformational, high-risk, early-stage research," and recently began funding ammonia synthesis technologies, not to make renewable fertilizer but to produce "energy-dense zero-carbon liquid fuel." This article will introduce the six electrochemical technologies currently in development with funding from ARPA-E.
At the recent NH3 Energy+ Topical Conference, Grigorii Soloveichik described the future of ammonia synthesis technologies as a two-way choice: Improvement of Haber-Bosch or Electrochemical Synthesis.
Two such Haber-Bosch improvement projects, which received ARPA-E-funding under Soloveichik's program direction, also presented papers at the conference. They each take different approaches to the same problem: how to adapt the high-pressure, high-temperature, constant-state Haber-Bosch process to small-scale, intermittent renewable power inputs. One uses adsorption, the other uses absorption, but both remove ammonia from the synthesis loop, avoiding one of Haber-Bosch's major limiting factors: separation of the product ammonia.
During our NH3 Energy+ Topical Conference, hosted within AIChE's Annual Meeting earlier this month, an entire day of presentations was devoted to new technologies to make industrial ammonia production more sustainable.
One speaker perfectly articulated the broad investment drivers, technology trends, and recent R&D achievements in this area: the US Department of Energy's ARPA-E Program Director, Grigorii Soloveichik, who posed this question regarding the future of ammonia production: "Improvement of Haber-Bosch Process or Electrochemical Synthesis?"
