Scaling Ammonia-to-Power Innovation with High-Performance Cloud Simulation

Rescale is proud to feature this customer spotlight highlighting Amogy’s clean-energy innovation powered by their use of advanced engineering methods on Rescale. The blog is guest-written by Chaitanya Wadkar with contributions from Matthew Montgomery and Allison Agre.

Amogy’s mission to decarbonize heavy-duty transportation and stationary power depends on advancing ammonia-to-power systems that can operate reliably at commercial scale. As technology has matured, reactor platforms have expanded significantly in size and throughput, introducing new complexities in fluid dynamics, heat transfer, and reactive behavior. These challenges have elevated the importance of high-fidelity simulation as a core driver of design verification and innovation.

To support this rapid scale-up, Amogy’s engineering team developed a unified multi-physics modeling framework capable of capturing detailed flow characteristics, mixing patterns, thermal gradients, and reaction pathways within a single simulation environment. This integrated approach reflects the tightly coupled nature of the system and enables accurate analysis across a wide range of operating conditions. As reactor geometries grew and operating regimes intensified, this unified workflow became essential in resolving performance-sensitive interactions that influence conversion efficiency, stability, and scalability.

Larger commercial reactor designs required mesh sizes several times greater than earlier prototypes, with computational domains that reflect higher mass-flow rates and increasingly complex internal features. These increases placed substantial demands on solver stability, memory footprint, and parallel performance. At this stage, consistent access to scalable high-performance computing became indispensable. Rescale’s digital engineering platform provided the elasticity and throughput needed to execute these expanded simulations without bottlenecks, queue delays, or resource conflicts. The ability to scale seamlessly allowed the team to iterate rapidly, evaluate multiple design configurations, and uncover insights that would have been difficult to obtain through hardware testing alone.

As reactor development progressed, simulation became tightly coupled with cross-functional engineering workflows. Design iterations required close coordination across mechanical design, manufacturing, and structural analysis teams, all operating against aggressive timelines and evolving regulatory constraints. Simulation results frequently served as gating inputs for downstream decisions, making turnaround time a critical factor in maintaining momentum across teams. In several instances, unanticipated design changes such as geometry refinements, material updates, or operating envelope adjustments required rapid validation to avoid schedule impacts. Cloud-based HPC through the Rescale platform enabled these urgent simulations to be launched immediately at full scale, preserving development timelines while maintaining model fidelity. As a result, product design cycle times were reduced by as much as 60%, despite the increased complexity of unified multi-physics workflows and scaled reactor architectures. This was made possible through interactive workstation capabilities that allowed real-time adjustments to ongoing simulations, combined with high-performance core architectures that reduced per-iteration solve times by up to 50%. Together, these capabilities enabled more frequent design iterations, earlier identification of performance tradeoffs, and faster convergence on commercial-ready configurations.

The high-fidelity modeling framework and scalable simulation infrastructure now central to Amogy’s reactor development program were established via efforts led by Chaitanya Wadkar, one of the senior CFD engineers at Amogy. He said, “These contributions enabled the transition from early-stage prototypes to commercial-scale reactor architectures and created the simulation foundation that supports design decisions across multiple product generations. This framework continues to guide Amogy’s technology roadmap and has become a cornerstone of the company’s ability to accelerate innovation in ammonia-to-power systems.” 

High-performance simulation proved especially valuable during early validation phases, where understanding subtle interactions within the reactor shortened development cycles and reduced prototyping risks. Cloud-scale compute resources allowed the team to explore parameter spaces comprehensively, sharpen predictive accuracy, and converge on design solutions compatible with commercial operating environments. This accelerated feedback loop strengthened the foundation for Amogy’s next-generation systems and helped drive the transition from pilot-scale demonstrations toward larger, market-ready units.

As Amogy continues to expand its technology platform, scalable simulation remains central to accelerating discovery, reducing uncertainty, and guiding system optimization. With the support of Rescale’s cloud HPC environment, the engineering team can pursue increasingly ambitious reactor architectures while maintaining the speed and rigor required for commercialization. This integrated approach to modeling and compute provides a critical advantage as the company works to deliver high-impact, zero-emission energy solutions for a decarbonizing world.
