Pathways to electrolysis success for USA, Australia

Julian Atchison December 16, 2024

In order to achieve the aggressive Hydrogen Shot initiative goal of $1/kg production cost by 2030, the US Department of Energy sets out a series of performance and capital cost targets for established and lower-TRL electrolyser technologies. Meanwhile, Australia's national science agency CSIRO projects that Australia’s hydrogen electrolyser manufacturing sector could generate AU$1.7 billion in revenue annually by 2050.

Decarbonizing existing, SMR-based ammonia plants: workshop recap

Kevin Rouwenhorst November 26, 2023

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.

Electric Heating Solutions for SMR-Based Ammonia Plants

Dave Yeardye

This presentation underscores the well-established and advantageous role of electric heaters in transforming heating processes within ammonia production, with insightful parallels drawn to the broader trend of electrification in various industries. Electric heaters have emerged as a tried-and-true alternative, and this session will delve into their numerous benefits, making a compelling case for their adoption. As industries worldwide are increasingly electrifying their heating processes to combat emissions, we will explore the technical and operational advantages of electric heaters, specifically within the context of ammonia production, utilizing the Haber-Bosch method. With a focus on reducing emissions, enhancing efficiency, and reducing maintenance…

Solid oxide electrolysis: building capacity

Kevin Rouwenhorst May 22, 2023

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.

Coupling solid oxide electrolysis to ammonia production

Kevin Rouwenhorst February 07, 2023

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.

A road ahead via lithium-mediated electrochemical nitrogen reduction?

Kevin Rouwenhorst October 03, 2022

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.

Nitrogen Reduction Reaction at High Current-to-Ammonia Efficiency

Hoang-Long DuAlexandr SimonovDouglas MacFarlane

Apart from its use in the fertiliser and chemical industries, ammonia is currently attracting our community as a potential carbon-neutral fuel and as an energy carrier for worldwide transportation of renewable sources. To achieve this goal, replacements of the conventional hydrocarbon deposit-based technology for NH3 production require to be a green but inexpensive and scale-flexible technology, namely the only genuine electrochemical lithium-mediated nitrogen reduction reaction (Li-NRR). Reported by many research groups around the world, the process had so far been hampered by poor yield rates and efficiencies. At Monash University, we introduced a compact ionic assembly arranged in the electrode-electrolyte…
