New Twists for Japanese Ene Farms

Over the last two months, Japan’s Ministry of Economy, Trade and Industry (METI) has selected at least four natural gas utilities to participate in “verification projects” under its Building Virtual Power Plant Using Customer-Side Energy Resources program. Participating utilities so far include Osaka Gas, Tokyo Gas, Seibu Gas, and J Power. The program is intended to facilitate the development of renewable electricity in Japan and is shining a new light on the deployment of fuel cells in the country's built environment.

Environmental and Economic Assessment of Ammonia as a Fuel for Ships

This month, the Korean Register published a comparative assessment of the environmental and economic merits of using ammonia as a maritime fuel. The work, written in collaboration with researchers at Pusan National University, is published in the open-access Journal of Marine Science and Engineering. It concludes that "ammonia can be a carbon-free fuel for ships," and presents "a meaningful approach toward solving GHG problems in the maritime industry."

Viking Energy to be retrofit for ammonia fuel in 2024

This morning, it was announced that the "Viking Energy," a supply vessel for Equinor's offshore operations, will be modified to run on a 2 MW direct ammonia fuel cell. This will be a five year project: the technology will be scaled-up on land before being installed on the vessel, which will begin a year of GHG emission-free operations in 2024. The Norwegian partners leading this "world's first" project include shipowner Eidesvik, contractor Equinor, and ammonia producer Yara, as well as Wärtsilä (Wärtsilä Norway), responsible for power technology and ammonia storage and distribution systems, and Prototech, delivering the fuel cell system.

Tri-State announces clean energy plan, retires coal assets

Yesterday, Tri-State Generation & Transmission Association launched its "transformative" Responsible Energy Plan, which will "dramatically and rapidly advance the wholesale power supply cooperative’s clean energy portfolio." Last week, the utility announced the retirement of its last coal-fired power plants in New Mexico and Colorado. These two announcements provide context for a presentation at the Ammonia Energy Conference in November 2019, entitled Market Integrated Ammonia. Its conclusion — highly relevant for a utility that is closing its coal plants and increasing renewables to 50% by 2024 — is that in a wholesale electricity market with increased volatility, renewable ammonia could be produced at the extremely low cost of $96 per tonne.

Green Ammonia Production Integrated into US Wholesale Power Markets

The High Plains and Rocky Mountain regions of the United States have some of the best renewable energy resources in the world. As more non-dispatchable wind and solar generation is integrated into the power system, it is impacting wholesale power markets. Average wholesale electricity power prices are falling while their volatility is increasing. This creates opportunities for large flexible loads that are capable of consuming energy while prices are low and not consuming energy when prices are high. Result from an analysis of dispatchable fully electric ammonia production integrated into the power system are presented.

Safe and Effective? New Study Evaluates Ammonia as a Marine Fuel

In mid-June the Dutch naval architecture firm C-Job released "Safe and effective application of ammonia as a marine fuel," a thesis written by the firm’s Lead Naval Architect Niels de Vries for the Marine Technology Master of Science program at the Delft University of Technology in the Netherlands. While the thesis delivers an extensive assessment of ammonia's potential effectiveness as a marine fuel, it breaks new ground in its consideration of ammonia's safety in this context.

Green ammonia: Haldor Topsoe’s solid oxide electrolyzer

Haldor Topsoe has greatly improved the near-term prospects for green ammonia by announcing a demonstration of its next-generation ammonia synthesis plant. This new technology uses a solid oxide electrolysis cell to make synthesis gas (hydrogen and nitrogen), which feeds Haldor Topsoe's existing technology: the Haber-Bosch plant. The product is ammonia, made from air, water, and renewable electricity. The "SOC4NH3" project was recently awarded funds from the Danish Energy Agency, allowing Haldor Topsoe to demonstrate the system with its academic partners, and to deliver a feasibility study for a small industrial-scale green ammonia pilot plant, which it hopes to build by 2025. There are two dimensions to this technology that make it so important: its credibility and its efficiency.

Ammonia for Fuel Cells: AFC, SOFC, and PEM

In the last 12 months ... IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.

Ammonia for Fuel Cells: a literature review

I wrote earlier today about a new literature review on "Ammonia for Power," published in November 2018. As a companion piece to that article, I'd like to highlight another open-access literature review, this one published a few years before we launched Ammonia Energy, which focuses completely on the (perhaps unexpectedly) broad subject of direct ammonia fuel cells. The mini-review, "Ammonia as a suitable fuel for fuel cells," was published in the August 2014 edition of Frontiers in Energy Research, written by Rong Lan and Shanwen Tao of the University of Strathclyde in the UK.

Toyota, 7-Eleven to Cooperate on Low-Carbon Convenience Stores

Last month, one Ammonia Energy post discussed Toyota’s participation in a Low-Carbon Hydrogen Project in its home prefecture -- including implicit support for ammonia as a hydrogen carrier.  Another post discussed Japanese manufacturer IHI’s plans to commercialize a small-scale combined heat and power system (micro CHP) based on direct ammonia solid oxide fuel cell technology.  Now, according to a June 6 Toyota Motor Corporation press release, Toyota and micro CHP have converged. The announcement served as the unveiling of a “joint project” by Toyota and the convenience store chain 7-Eleven to develop “next-generation convenience stores aiming to considerably reduce CO2 emissions.”  The two companies initially agreed to cooperate in August 2017 on "considerations toward energy conservation and carbon dioxide emission reduction in store distribution and operation.”
