US-based Syzygy Plasmonics announced successful final tests of its light-powered ammonia cracking technology. More than 1,500 hours of testing have validated the production of hydrogen from ammonia in the reactor cell, which is now available to order as a stacked, 5 tons per day capacity system.
Decarbonization of existing steam methane reforming-based ammonia plants is possible, and changes in gas and heat flows can be recovered via alternative technologies. Recap our workshop in Atlanta, where we discussed the use of upstream methane monitoring equipment, electrolysers, carbon capture, hydrogen burners, energy storage and electric heating to achieve decarbonization of conventional ammonia plants.
Solid oxide electrolysis has recently gained traction, and is fast becoming an attractive technology option for new ammonia production projects. This week we will explore a recent ISPT report, the scale-up of Topsoe’s manufacturing capacity, and several project announcements.
In our January episode of Ammonia Project Features, we explored the current commercial status of solid oxide electrolysis, and its potential to be integrated with ammonia production. Rick Beuttel (Bloom Energy) and Jakob Krummenacher (LSB industries) also discussed the utilization of the technology in a new decarbonization project at LSB’s ammonia plant in Pryor, Oklahoma.
Realisation of electrochemical nitrogen reduction to ammonia has proven to be a herculean scientific challenge. Recently, a focus on Lithium-mediated synthesis has delivered promising results. Last year a team from Monash University in Australia unveiled their phosphonium “proton shuttle” method, and this year have reported nearly 100% Faradaic efficiency for the reaction (with promising reaction rates). Late last year, a team from the Technical University of Demark (DTU) reported that addition of small amounts of oxygen gas drastically increased Faradaic efficiencies and production rates. The results push electrochemical synthesis R&D ever-closer to elusive benchmarks set for commercial realisation.
