Iceland's Atmonia innovates ammonia production by using a single-step electrochemical method, aiming for decentralized systems that minimize energy demands.
Ammonia plays a pivotal role in modern agriculture, yet traditional methods — particularly the Haber-Bosch process — are energy-intensive and require large-scale industrial infrastructure. In response to this challenge, Atmonia, an Iceland-based company, is pioneering a single-step electrochemical process designed to simplify ammonia production and significantly reduce carbon emissions.
Founded in 2016, Atmonia has spent the last decade refining patented catalysts that facilitate ammonia production directly from nitrogen and water at ambient temperature and pressure. This technique eliminates the need for hydrogen production and storage, streamlining the process into a more compact and efficient framework.
Innovative Electrolyzer Technology
Atmonia employs a specially adapted nitrogen electrolyzer that functions akin to an anion exchange membrane (AEM) aqueous electrolyzer. This device integrates a membrane electrode assembly allowing nitrogen gas to access the catalyst directly via gas diffusion. The scalability of electrolyzers is one of their key attributes; Atmonia’s approach follows a two-dimensional scalability model rather than a three-dimensional one, which is typical in larger setups.
Currently, the company is using an electrode size of 10 square centimeters, with plans to scale up to 400 square centimeters, followed by the introduction of stacked cells similar to existing AEM systems. This phased scaling strategy enhances their capacity to generate ammonia while maintaining efficiency.
Predictions for Scaling and Efficiency
Co-founder and CEO Helga Dögg Flosadóttir expressed optimism regarding the predictability of scaling: “To a certain degree, yes. We can demonstrate it on a small scale. Then we can use computational fluid dynamics to simulate how it will function on a larger scale.” However, she acknowledged the presence of unknown factors that will require optimization as they progress to handle larger operations.
Atmonia’s competitive edge in a burgeoning green ammonia market stems largely from its efficiency. The company is targeting decentralized ammonia production close to end-users, particularly small-scale farmers. By presenting a less energy-demanding and flexible solution, Atmonia aims to carve out a niche in what they predict will be a diverse marketplace catering to varying agricultural needs.
Developing Effective Catalysts
At the heart of their process lies a specialized catalyst developed through quantum chemical simulations. This focus on selectivity allows the catalyst to efficiently reduce nitrogen while minimizing the formation of unwanted hydrogen. Traditional catalysts tend to favor hydrogen production, which complicates ammonia synthesis, but Atmonia’s innovation seeks to overturn this tendency.
In a bid to further their mission, Atmonia plans to concentrate its business model on catalyst synthesis and electrode manufacturing while collaborating with other manufacturers for hardware and scaling. The catalysts are crafted from readily available materials, potentially lowering costs and enhancing sustainability compared to conventional methods.
Addressing Technical and Economic Bottlenecks
Despite having established the ammonia-producing chemistry, Dögg Flosadóttir mentioned that the key technical hurdles now involve fine-tuning energy demands. The optimization of both the catalyst and the overall reaction environment within the electrolyzer is essential for reaching economically viable production levels.
The company envisions scaling up to a compact 40-foot containerized production system capable of delivering approximately 150 tons of ammonia annually. This system is designed to ensure viability even under current electricity pricing, making it an attractive option for farmers.
A Targeted Business Model
Atmonia's business model focuses on being a producer of catalysts and electrodes while forming partnerships with hardware manufacturers. With Iceland's limited market saturation potential for their technology (estimated at 80 containers), they aim to expand globally, enhancing local production to meet the needs of farmers.
To lower the entry costs for farmers, Atmonia is also considering a leasing model, allowing users to access their systems without substantial upfront investments, which can discourage adoption in the agricultural sector.
Funding and Future Growth
The company's growth and research have heavily relied on grant funding from Icelandic research institutions, the European Innovation Council, and Horizon Europe. Additionally, Atmonia has attracted support from Icelandic venture capitalists as well as Canadian agricultural investors.
Currently, they have initiated a seed investment round, seeking to attract agritech and deep tech investors who understand the long-term horizons necessary for their endeavor. Achieving a technology readiness level (TRL) of 6 remains a priority, which would involve demonstrating a working prototype in a farm setting.
As the agricultural sector increasingly turns its attention toward sustainable practices, Atmonia's approach offers promising advancements in ammonia production that could help meet both current and future demands without the associated carbon footprint.
