IHI Corporation pushes its ammonia combustion technologies closer to commercialization

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)."

Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.

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.”

SIP “Energy Carriers” video: ammonia turbines, industrial furnaces, fuel cells

To demonstrate the progress of the SIP "Energy Carriers" program, the Japan Science and Technology Agency last week released a video, embedded below, that shows three of its ammonia fuel research and development projects in operation.

R&D is often an abstract idea: this video shows what it looks like to generate power from ammonia.

As it turns out, fuel cells aren't hugely photogenic. Nonetheless, if a picture is worth a thousand words, this will be a long article.

Ammonia-Fueled Solid Oxide Fuel Cell Advance at Kyoto University

Earlier this month the Eguchi Laboratory at Kyoto University announced advances in ammonia-fueled solid oxide fuel cell technology.  The lab was able to produce a functioning fuel cell with a power output of one kilowatt.  The device attained “direct current power generation efficiency” in excess of 50% and reached 1,000 hours of continuous operation.
