Starfire Energy’s 10 Kg/Day Rapid Ramp NH; System Development

Starfire Energy is building a 10 kg/day NH3 synthesis system using its low pressure Rapid Ramp NH3 process. The system includes hydrogen production by proton exchange membrane electrolyzer, nitrogen production by pressure swing adsorption, NH3 synthesis, and liquid NH3 storage. The tight coupling of the hydrogen, nitrogen, and NH3 processes require minimal reactant buffering. The system design, status, and preliminary performance will be discussed.

High Flow Ammonia Cracking between 400 600C

Traditional ammonia cracking is achieved at 850-950C in the presence of a nickel catalyst. The reaction is highly endothermic, and maintaining these high temperatures at high flow rates of ammonia gas can be difficult. Here, we present work using our advanced ammonia synthesis catalyst in an ammonia cracking setup. We use a metallic monolith catalyst support to minimize pressure drop at high flow rates. Full NH3 cracking occurs at 600C, with the onset of cracking at 400C. An output flame can be achieved with a fully tunable ratio of hydrogen to ammonia, depending on the temperature setpoint of the cracker.

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.”

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.
