ARPA-E solicits technologies for nitrogen extraction from seawater using seaweed

NEWS BRIEF: On Monday, May 13, the US Department of Energy ARPA-E will close its request for information (RFI) regarding Quantification of Effectiveness of Nutrient Bioextraction by Seaweed.

By using environmental remediation (nitrogen removal) as a mechanism for ammonia production (nitrogen recycling), this novel research area could connect together two phases of industry: production and end-of-life management. Rather than saying that this addresses both ends of a value chain, it might be more appropriate to say that this holds promise for the circular economy of ammonia energy.

ARPA-E request for information: Pre‐pilot and pilot projects to scale, mature, and advance technologies

ANNOUNCEMENT: The US Department of Energy's Advanced Research Projects Agency (ARPA-E) has published a Request For Information (RFI) focused on supporting scale-up demonstrations of ARPA-E technologies. Unlike normal ARPA-E funding agreements, which typically provide 5%-20% of the financing for bench-scale projects within laboratories, this RFI is geared towards industrial pilot projects, for which ARPA-E would provide "at least 50% cost share."

More Progress for Automotive-Oriented Direct Ammonia Fuel Cells

Shimshon Gottesfeld’s paper The Direct Ammonia Fuel Cell and a Common Pattern of Electrocatalytic Processes leads with a big number: “A record power density of 450 mW/cm2 has been demonstrated for a direct ammonia fuel cell [DAFC] using an alkaline membrane electrolyte.”  We know it’s big because it’s 80% higher than the 250 mW/cm2 that Gottesfeld’s team had achieved in the fall of 2017 and that Gottesfeld, Adjunct Professor of Chemical Engineering at the University of Delaware, reported at the November 2017 NH3 Energy+ Topical Conference.

NH3 Energy Implementation Conference: A Brief Report

The 2018 NH3 Energy Implementation Conference, the first of its kind, took place on November 1 in Pittsburgh, Pennsylvania in the U.S. The focus of the Conference was on steps – current and future – that will lead to implementation of ammonia energy in the global economy.  At the highest level, the Conference results validated the relevance and timeliness of the theme.  In the words of closing speaker Grigorii Soloveichik, Director of the U.S. Department of Energy’s ARPA-E REFUEL Program, the Conference strengthened his confidence that “ammonia is a great energy carrier ... with billions of dollars of potential in prospective markets.”

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.

Yara’s N-Tech Platform: Making Strides with Green Ammonia

Yara International, one of the world’s largest ammonia producers, is making strides in its development of green ammonia as a fertilizer, chemical intermediate, and energy carrier.  The progress is documented in the company’s 2017 annual report, released last week, and in more detail in a presentation delivered in late February at the 2018 Nitrogen + Syngas Conference in Gothenburg, Sweden.

Full program announced for the 2018 NH3 Event Europe

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.

Future Ammonia Technologies: Electrochemical (part 3)

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.

Progress for Low-Temperature Direct Ammonia Fuel Cells

Speaking at the NH3 Energy+ Topical Conference last month, University of Delaware Adjunct Professor Shimshon Gottesfeld reported on progress made by the university’s direct ammonia fuel cell (DAFC) project. Evidently, the UDel team is now a big step closer to its goal of establishing the DAFC as a viable automotive power plant.

Improvement of Haber-Bosch: Adsorption vs. Absorption

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.
